FDA approval on 12/1/2017 of Amgen’s evolocumb (Repatha) a PCSK9 inhibitor for the prevention of heart attacks, strokes, and coronary revascularizations in patients with established cardiovascular disease

Reporter: Aviva Lev-Ari, PhD, RN

 

Evolocumab was first FDA approved in 2015 for patients with

  • familial hypercholesterolemia and
  • others who fail to achieve LDL cholesterol lowering through diet and maximally-tolerated statin therapy.

In the Repatha cardiovascular outcomes study (FOURIER), Repatha reduced the risk of

  • heart attack by 27 percent, the risk of
  • stroke by 21 percent and the risk of
  • coronary revascularization by 22 percent.2

 

U.S. Repatha Indication

Repatha is a PCSK9 (proprotein convertase subtilisin kexin type 9) inhibitor antibody indicated:

  • to reduce the risk of myocardial infarction, stroke, and coronary revascularization in adults with established cardiovascular disease.
  • as an adjunct to diet, alone or in combination with other lipid-lowering therapies (e.g., statins, ezetimibe), for treatment of adults with primary hyperlipidemia (including heterozygous familial hypercholesterolemia [HeFH]) to reduce low-density lipoprotein cholesterol (LDL-C).
  • as an adjunct to diet and other LDL‑lowering therapies (e.g., statins, ezetimibe, LDL apheresis) in patients with homozygous familial hypercholesterolemia (HoFH) who require additional lowering of LDL‑C.

The safety and effectiveness of Repatha have not been established in pediatric patients with HoFH who are younger than 13 years old.

The safety and effectiveness of Repatha have not been established in pediatric patients with primary hyperlipidemia or HeFH.

Eligible patients with high cholesterol (LDL-C ≥70 mg/dL or non-high-density lipoprotein cholesterol [non-HDL-C] ≥100 mg/dL) and established cardiovascular disease at more than 1,300 study locations around the world were randomized to receive Repatha subcutaneous 140 mg every two weeks or 420 mg monthly plus high- or moderate-intensity effective statin dose; or placebo subcutaneous every two weeks or monthly plus high- to moderate-intensity statin dose. Statin therapy was defined in the protocol as at least atorvastatin 20 mg or equivalent daily with a recommendation for at least atorvastatin 40 mg or equivalent daily where approved. The study was event driven and continued until at least 1,630 patients experienced a key secondary endpoint.

About Repatha® (evolocumab)
Repatha® (evolocumab) is a human monoclonal antibody that inhibits proprotein convertase subtilisin/kexin type 9 (PCSK9). Repatha binds to PCSK9 and inhibits circulating PCSK9 from binding to the low-density lipoprotein (LDL) receptor (LDLR), preventing PCSK9-mediated LDLR degradation and permitting LDLR to recycle back to the liver cell surface. By inhibiting the binding of PCSK9 to LDLR, Repatha increases the number of LDLRs available to clear LDL from the blood, thereby lowering LDL-C levels.1

About Amgen in the Cardiovascular Therapeutic Area
Building on more than three decades of experience in developing biotechnology medicines for patients with serious illnesses, Amgen is dedicated to addressing important scientific questions to advance care and improve the lives of patients with cardiovascular disease, the leading cause of morbidity and mortality worldwide.8 Amgen’s research into cardiovascular disease, and potential treatment options, is part of a growing competency at Amgen that utilizes human genetics to identify and validate certain drug targets. Through its own research and development efforts, as well as partnerships, Amgen is building a robust cardiovascular portfolio consisting of several approved and investigational molecules in an effort to address a number of today’s important unmet patient needs, such as high cholesterol and heart failure.

Homozygous Familial Hypercholesterolemia (HoFH): In 49 patients with homozygous familial hypercholesterolemia studied in a 12-week, double-blind, randomized, placebo-controlled trial, 33 patients received 420 mg of Repatha subcutaneously once monthly. The adverse reactions that occurred in at least 2 (6.1 percent) Repatha-treated patients and more frequently than in placebo-treated patients, included upper respiratory tract infection (9.1 percent versus 6.3 percent), influenza (9.1 percent versus 0 percent), gastroenteritis (6.1 percent versus 0 percent), and nasopharyngitis (6.1 percent versus 0 percent).

Immunogenicity: Repatha is a human monoclonal antibody. As with all therapeutic proteins, there is a potential for immunogenicity with Repatha.

Trends in HealthCare Economics: Average Out-of-Pocket Costs, non-Generics and Value-Based Pricing, Amgen’s Repatha and AstraZeneca’s Access to Healthcare Policies

Reporter: Aviva Lev-Ari, PhD, RN

 

1.   AstraZeneca’s access to healthcare strategy is made up of three elements:

  • Provide high-quality, effective and appropriate medicines to those who need them. Improve affordability, particularly among the growing middle class in Emerging Markets.
  • Bring down healthcare barriers, particularly in developing countries. Our strategy helps us to address affordability and other healthcare barriers, while ensuring we continue to provide high-quality medicines to those who need them.
  • Key Target exceeded Full target achieved Ongoing progress Target not achieved, some progress AstraZeneca has extensively expanded and updated their access strategy identifying those areas where they are best placed to provide support and are now well positioned for future progress.”
  • Access to Medicine Index Access to healthcare Goals Target progress Progress highlights Expand sustainable patient access to our medicines to reach 3 million patients by 2016 4.49 million patients in Emerging Markets served by patient access programmes
  • Young Health Programme After exceeding initial goal to reach 1 million people through the Young Health Programme by 2015, aim to renew in five markets and expand into three markets by 2018 Renewed in Canada, Germany, China and India and expanded into Kenya
  • Total reach in 2016 of 166,000 and 1.6 million youth since 2010
  • Proposals for expansion are in development for Brazil and Australia and for renewal in Portugal
  • Healthy Heart Africa Reach 10 million hypertensive patients across Sub-Saharan Africa by 2025 Since 2014, we have conducted over 2.7 million screenings and started treatment for over 100,000 hypertensive patients

2.   Co-Development and Commercialization by Territory

AstraZeneca has paid $45 million and committed to up to $2.1 billion in milestones to team with Pieris Pharmaceuticals. The agreement sets Pieris up to move respiratory candidate PRS-060 into the clinic on AstraZeneca’s dime and pull in milestones as it and other pipeline prospects advance.

Tiny Pieris is due to receive the first, $12.5 million milestone when it moves moderate to severe asthma candidate PRS-060 into phase 1. AstraZeneca will fund clinical development of the interleukin-4 receptor alpha-targeting protein. If the asset reaches phase 2a, Pieris has the option to codevelop and commercialize it in the U.S., bumping up the royalties or gross margin share it receives in the process.

Pieris has a similar codevelopment option on other assets covered by the agreement. The biotech will develop four other proteins against undisclosed respiratory targets. If Pieris wants, it can sign up to codevelop and commercialize two of these programs in the U.S. Milestones and commercial payments across the deal could ultimately total $2.1 billion.

3.  Prescriptions Dispensed at Zero Patient Out-of-Pocket Cost Reached Thirty Percent in 2016

29.9% of prescriptions have been dispensed at zero patient out-of-pocket cost, including brands and generics, up 1.5% since 2015, all due to increased use of zero cost generics.
The total share of prescriptions where patients paid some amount less than $50 declined by 1.3% to 67.8% in 2016.
The proportion of claims with patient cost exposure greater than $50 increased also declined slightly from 2.5% to 2.3% in 2016.

Since 2013, Average Out-of-Pocket Costs for All Brand and Generic Prescriptions has Decreased by $1.19

Average patient out of pocket costs declined from $9.66 in 2013 to $8.47 in 2016, with 2016 brand costs declining to $28.31 from $32.36 in 2013 and generics dipping to $5.54 from a high of $6.05 in 2013.
The list prices of brands continue to be far higher than the average paid by patients, as few patients are exposed to those costs in their insurance plans.
The average list price for brands averaged 12 times higher than the average out of pocket cost for patients in 2016 compared to 3 times higher for generics.

4.   Harvard Pilgrim Signs Second Groundbreaking Contract with Amgen For Repatha

HPHC and its members will receive full refund if a cardiac event occurs while on the drug

(WELLESLEY, MA) – Harvard Pilgrim Health Care has entered into a first-of-its-kind contract with Amgen for its LDL cholesterol lowering drug, Repatha, that guarantees the health plan and its members will receive a full refund of their costs for the drug if a member is hospitalized for a myocardial infarction or stroke after taking Repatha for six months or more and maintaining an appropriate level of compliance on the drug.

Repatha is one of a new class of biotechnology medicines known as PCSK9 inhibitors that have demonstrated a promising new approach for treating elevated LDL cholesterol in patients whose levels are not able to be controlled by current treatment options. The medication is designed to target a protein that prevents the body from removing artery-blocking LDL cholesterol from the bloodstream. Repatha works differently than statin drugs that prevent the liver from making cholesterol.

Given by injection every two or four weeks, Repatha is intended for patients who have an inherited disorder resulting in high levels of LDL cholesterol or have high-risk atherosclerotic cardiovascular disease conditions, such as heart attack or stroke, that have been resistant to treatment.

“Repatha has been shown to have a significant outcome on reducing cardiovascular morbidity for high risk individuals with elevated LDL cholesterol,” said Harvard Pilgrim Chief Medical Officer Michael Sherman. However, there have been concerns raised about the cost of this new drug relative to existing statin treatments. We hope to negotiate more contracts of this type, in which a pharmaceutical company truly has ‘skin in the game’ going forward. This agreement is the first we have signed in which there is a full refund of all costs related to the medication if the patient experiences a heart attack or stroke while taking it.”

“Cardiovascular disease is the largest public health concern in the world and for high-risk patients who have already had a cardiovascular event or whose genetics puts them at risk, it is important that these patients have access to an effective treatment shown to lower their

elevated LDL cholesterol in addition to their current lipid lowering regimen,” said Joshua J. Ofman, M.D., MSHS, senior vice president of Global Value, Access & Policy. “Amgen’s agreement with Harvard Pilgrim demonstrates our commitment to seeking innovative approaches that help break down the barriers of access to Repatha.”

This is the second patient-focused outcomes contract Harvard Pilgrim has negotiated with Amgen for Repatha. In the fall of 2015, the health plan signed an outcomes guarantee through which Amgen provided HPHC with an enhanced discount if the reduction in LDL levels for Harvard Pilgrim members is less than what was observed during Repatha’s clinical trials. In addition, the agreement provides for additional discounts if the utilization of the drug exceeds certain levels. This enables those patients who can most benefit from the drug to receive it while continuing to encourage utilization of lower cost statins for the majority of patients.

Regulatory MicroRNAs in Aberrant Cholesterol Transport and Metabolism

Curator: Marzan Khan, B.Sc

Aberrant levels of lipids and cholesterol accumulation in the body lead to cardiometabolic disorders such as atherosclerosis, one of the leading causes of death in the Western World(1). The physical manifestation of this condition is the build-up of plaque along the arterial endothelium causing the arteries to constrict and resist a smooth blood flow(2). This obstructive deposition of plaque is merely the initiation of atherosclerosis and is enriched in LDL cholesterol (LDL-C) as well foam cells which are macrophages carrying an overload of toxic, oxidized LDL(2). As the condition progresses, the plaque further obstructs blood flow and creates blood clots, ultimately leading to myocardial infarction, stroke and other cardiovascular diseases(2). Therefore, LDL is referred to as “the bad cholesterol”(2).

Until now, statins are most widely prescribed as lipid-lowering drugs that inhibit the enzyme 3-hydroxy-3methylgutaryl-CoA reductase (HMGCR), the rate-limiting step in de-novo cholesterol biogenesis (1). But some people cannot continue with the medication due to it’s harmful side-effects(1). With the need to develop newer therapeutics to combat cardiovascular diseases, Harvard University researchers at Massachusetts General Hospital discovered 4 microRNAs that control cholesterol, triglyceride, and glucose homeostasis(3)

MicroRNAs are non-coding, regulatory elements approximately 22 nucleotides long, with the ability to control post-transcriptional expression of genes(3). The liver is the center for carbohydrate and lipid metabolism. Stringent regulation of endogenous LDL-receptor (LDL-R) pathway in the liver is crucial to maintain a minimal concentration of LDL particles in blood(3). A mechanism whereby peripheral tissues and macrophages can get rid of their excess LDL is mediated by ATP-binding cassette, subfamily A, member 1 (ABCA1)(3). ABCA1 consumes nascent HDL particles- dubbed as the “good cholesterol” which travel back to the liver for its contents of triglycerides and cholesterol to be excreted(3).

Genome-wide association studies (GWASs) meta-analysis carried out by the researchers disclosed 4 microRNAs –(miR-128-1, miR-148a, miR-130b, and miR-301b) to lie close to single-nucleotide polymorphisms (SNPs) associated with abnormal metabolism and transport of lipids and cholesterol(3) Experimental analyses carried out on relevant cell types such as the liver and macrophages have proven that these microRNAs bind to the 3’ UTRs of both LDL-R and ABCA1 transporters, and silence their activity. Overexpression of miR-128-1 and miR148a in mice models caused circulating HDL-C to drop. Corroborating the theory under investigation further, their inhibition led to an increased clearance of LDL from the blood and a greater accumulation in the liver(3).

That the antisense inhibition of miRNA-128-1 increased insulin signaling in mice, propels us to hypothesize that abnormal expression of miR-128-1 might cause insulin resistance in metabolic syndrome, and defective insulin signaling in hepatic steatosis and dyslipidemia(3)

Further examination of miR-148 established that Liver-X-Receptor (LXR) activation of the Sterol regulatory element-binding protein 1c (SREBP1c), the transcription factor responsible for controlling  fatty acid production and glucose metabolism, also mediates the expression of miR-148a(4,5) That the promoter region of miR-148 contained binding sites for SREBP1c was shown by chromatin immunoprecipitation combined with massively parallel sequencing (ChIP-seq)(4). More specifically, SREBP1c attaches to the E-box2, E-box3 and E-box4 elements on miR-148-1a promoter sites to control its expression(4).

Earlier, the same researchers- Andres Naars and his team had found another microRNA called miR-33 to block HDL generation, and this blockage to reverse upon antisense targeting of miR-33(6).

These experimental data substantiate the theory of miRNAs being important regulators of lipoprotein receptors and transporter proteins as well as underscore the importance of employing antisense technologies to reverse their gene-silencing effects on LDL-R and ABCA1(4). Such a therapeutic approach, that will consequently lower LDL-C and promote HDL-C seems to be a promising strategy to treat atherosclerosis and other cardiovascular diseases(4).

Europeans Mull PCSK9i Post-FOURIER Fallout on Clinical Practice

Patrice Wendling, May 04, 2017

But it was panelist Dr Stephen Nicholls (University of Adelaide, Australia) who took aim at the elephant in the packed auditorium. At an annual cost of about $14,100 for evolocumab and $14,600 for alirocumab (Praluent, Sanofi/Regeneron), the important question facing cardiologists is who will be eligible for these drugs “in a world where we can’t just write a scrip for every FOURIER-type patient; we won’t be allowed to.”

He suggested initially this will include patients with familial hypercholesterolemia and only those with established atherosclerotic CVD whose LDL-C remains unacceptably high despite therapy. Future FOURIER subanalyses may define other eligible high-risk groups.

PCSK9 Inhibitor Access Snarled in Red Tape, Rejections

Patrice Wendling, March 21, 2017

To determine whether this experience is happening nationwide, Navar and colleagues examined first PCSK9 prescriptions in 45,029 patients (median age 66 years; 51% female) between August 1, 2015 and July 31, 2016 in the Symphony Health Solutions database, which covers 90% of retail, 70% of specialty, and 60% of mail-order pharmacies in the US.

Nearly half (48%) of prescribers were cardiologists, and 37% were general practitioners. Most patients (52%) had government insurance, typically Medicare, and 40% had commercial insurance.

In the first 24 hours after being submitted to the pharmacy, 79.2% of prescriptions were rejected. Ultimately, 52.8% of all PCSK9 prescriptions were rejected.

Of special note, 34.7% of prescriptions for the pricy lipid-lowering drugs were abandoned at the pharmacy.

How 2 Drugs Lower Cholesterol Remarkably — and Reverse Heart Disease

Study shows promise for combination of newer drug and statins

How 2 Drugs Lower Cholesterol Remarkably --- and Reverse Heart Disease

Newer cholesterol-lowering drugs combined with more conventional medicine reduces bad cholesterol to incredibly low levels, a new study shows. Perhaps even more important, the combination also reduces the heart-attack-inducing plaque that forms inside the arteries, the study says.

The study was led by cardiologist Steven Nissen, MD, Chairman of Cardiovascular Medicine at Cleveland Clinic. Results appeared recently in the Journal of the American Medical Association (JAMA).

The study looked at the use of a drug called evolocumab by people who took statins to lower the amount of LDL, or bad, cholesterol in their blood. Evolocumab is a drug called a PCSK9 inhibitor. This is a newer kind of medicine that can make LDL cholesterol levels plummet.

The people who took statins and evolocumab had greater reductions in atherosclerosis compared with people who took statins and a placebo.  Atherosclerosis is  a disease in which plaque builds up inside your arteries.  The condition can lead to serious problems, including heart attack, stroke, or even death.

The results are an intriguing indicator — rather than definite proof — that evolocumab may have benefit for patients taking statins, Dr. Nissen says. Researchers are still awaiting the results of large clinical trials investigating whether evolocumab is safe and will prevent heart attack, stroke or death. The first results of these studies are expected in April 2017.

Special ultrasound

In the study, researchers treated for 18 months 968 high-risk people who had extremely high levels of blood cholesterol.

Participants were randomly assigned to take either a statin and a placebo, or a statin and evolocumab.

Researchers monitored the participants’ cholesterol levels. They also used a special ultrasound probe to measure the amount of plaque in their arteries at the beginning and the end of the study. 

“We were able to show that getting the bad cholesterol levels down to really low levels, down to the 20s and 30s, can actually remove plaque from the coronary arteries,” Dr. Nissen says. “This going to levels that we’ve never been able to achieve before.”           

Low cholesterol, less plaque

Results show the group treated with statins and a placebo reduced their LDL cholesterol levels to 93 on average. At the same time, the group treated with the combination of the statin plus evolocumab got down to an average bad cholesterol level of 36.6.

“No one’s ever reached levels that low in a clinical trial,” Dr. Nissen says.

Participants who took evolocumab also had less plaque in their arteries at the end of the study — essentially reversing their heart disease.

“We, for the first time now, have shown that this new class of drugs, the PCSK9 inhibitors, has a favorable effect on the development of plaques on the coronary artery and can actually regress those plaques,” Dr. Nissen says. “And it turns out about two-thirds of patients actually had less plaque at the end of 18 months than they started with.” 

PCSK9 inhibitors, which are expensive, are not for everybody, Dr. Nissen says. Currently, the drug is used in addition to statins for the highest-risk patients with particularly high cholesterol.

8:40 Non-Alcoholic Steatohepatitis and Cardiovascular Disease: Modulation by Novel PPAR Agonists

Bart Staels, Ph.D., Professor, INSERM, University of Lille, Pasteur Institute

Peroxisome proliferator-activated receptors (PPARs) are ligand-activated nuclear receptors which regulate lipid and glucose metabolism as well as inflammation. In this presentation, we will review recent findings on the pathophysiological role of PPARs in the different stages of non-alcoholic fatty liver disease (NAFLD), from steatosis development to steatohepatitis and fibrosis, as well as the preclinical and clinical evidences for potential therapeutical use of PPAR agonists in the treatment of NAFLD. PPARs play a role in modulating hepatic triglyceride accumulation, a hallmark of the development of NAFLD. Moreover, PPARs may also influence the evolution of reversible steatosis towards irreversible, more advanced lesions. Large controlled trials of long duration to assess the long-term clinical benefits of PPAR agonists in humans are ongoing.

Non-Alcoholic Steatohepatisis and CVD – Meta inflammatory disease

  • NAFL — abnormal Lipid accumulation
  • NASH >> Balooning, FIbrosis inflamation
  • Resolution of NASH is associated with reduction of Fibrosis (Golden – 505 trial)

CVD is linked to NAFLD: Lipids elevated and therosclerosis

10:25 Targeting Fibroblast Activation Protein (FAP) and FGF21 to Treat Fatty Liver Disease

Diana Ronai Dunshee, Ph.D., Department of Molecular Biology, Senior Scientific Researcher, Genentech, Inc.

FGF21 is a hormone with anti-obesity and hepatoprotective properties. However, the beneficial effects of FGF21 are limited by a relatively short half-life in circulation. We discovered that fibroblast activation protein (FAP), an endopeptidase overexpressed in liver with cirrhosis, cleaves and inactivates FGF21. Pharmacological inhibition of FAP increases endogenous levels of active FGF21, thus making FAP a promising target for the treatment of non-alcoholic-steatohepatitis (NASH).

  • Medical complications of obisity: NASH and DM-2
  • energy consumption
  • white adipose tissue – energy storage
  • brown adipose tissue matochondia’s energy
  • FGF21 – Human activation of protein cleavage: A Homone beneficial on metabolic health circulation, weigh loss
  • it suppreses hepatic Steatohepatitis
  • One singleinjection in mice — leads to energy expenditure induced weigh loss and metabolic improvement in Obese Humans
  • Negative FGF21 is Rapidly Eliminated from the body – renal degradation and Inactivation of FGF21 Endopeptidase Cleavage Site – Fibroblast Activation Protein Matched FAP Endopeptidease Specificity
  • Closest relative of DPP4 upregulted during tissue injury in NASH
  • FAP is SUfficient to Cleave FGF21
  • Recombinant FGF21 with Recombinant FAP in Serum or Plasma
  • FAP Protease – Serum Immunodepleted Ablates FGF21 Cleavage Activity: Peptide IgG vs anti-FAP
  • FAP Cleavage Inactivates Human FGF21 dependent on KLB-FGFR1c placed on the site
  • hFGF21 in Not Cleaved in FAP KO Mice
  • Fc-hFGF21 is more stable in FAP KO mice
  • FAR cleaves Endogenously Produced FGF21 In Vivo in monkeys and in dogs
  • The FAP Cleavage Consensus GLY-Pro is COnserved in most mammalian FGF21
  • FAP Does not Cleave the C-Terminal Residues of Mouse FGF21
  • Human: FAP, DPPIV
  • Mouse: FAP, DPP4
  • FAP INhibition

10:55 Thyroid Hormone Receptor Beta (THR-ß) Agonist for NASH: Correcting a Primary Deficiency in NASH Livers

Rebecca Taub, M.D., Ph.D., CEO, Madrigal Pharmaceuticals

NASH patients typically have metabolic syndrome including diabetes, dyslipidemia, obesity, and primarily die of cardiovascular disease. Hypothyroidism at the level of the thyroid gland and liver-specific hypothyroidism are common in NASH. Based on clinical and preclinical data, Thyroid receptor beta agonists decrease insulin resistance, reduce LDL-C, triglycerides fatty liver, inflammation and fibrosis in NASH. The target will also provide CV benefit to patients with NASH. MGL-3196 is a highly THR-ß selective liver-directed once daily oral medication that has shown excellent safety and lipid-lowering efficacy in humans; unlike prior thyroid receptor agonist(s), no cartilage findings in chronic toxicology or ALT increases in human studies. MGL-3196 is being advanced in Phase II studies in patients with genetic dyslipidemia or NASH.

Madrigal Portfolio of drugs:

  • MGL-3196: First-in-Class THR-Beta Agonist – discovered first at ROCHE – THR-beta selective targeted to the Liver – regulated by THR-Alpha  – in Phase II – no side effects on bone
  • Large & underserved Markets in NASH
  • Phase 2 HeFH Patients
  1. Hypothyroidism common in NASH patients
  2. Liver-specific Hypothyroidism present in human NASH degradation of thyroid hormone increases deiodised 9DIO) 3 produced by Stelllate cells in NASH liver
  3. Treating NASHrather than fibrosis is key in addressing the disease – approvable endpoint
  4. THR – Thyroid hormone reduces Cholesterol
  5. Thyroid hormone T3 thyroxine – treatment amy cause osteoporosis
  6. MGL 0 3196: Liver size, Live Triglycerides, Improve Insulin tolerance, decrease ALT
  7. Reduction of key NASH, Fibrosis Pathway Genes at Human Comparable Drug levels
  8. THR-beta: Decreased Liver Fibrosis, Apoptosis in mice:

Gene Therapy Breakthroughs

New Strategies for Better Specificity and Delivery

 

2:05  Chairman’s Remarks

Joseph Gold, Ph.D. Director Manufacturing Center for Biomedicine and Genetics, Beckman Research Institute City of Hope

 

  • CBG (center for biomedicine and Genetics) 20000 sq feet
  • CTPC (center therapy production) mainly CART
  • CBG 16 years operation do all stem cells and >400 products
  • New stem cell Beta cell progenitor
  • Do oncolytic VSV
  • CTPC is investigator driven CART islet cells,
  • Like to do novel work so work with CIRM
  • Banking of modified stem cells
  • Adherent scale out limitations: cost,inefficient; solution can be suspension
  • Establish hESC; plate on CELLstart > Accutase>StemPRO SFM>differentiation process; defined reagents — they use this for cardiomyocyte differentiation: they are functional (inotropy, chronotropy response to isoproterenol) can freeze back cells
  • Create a bank of intermediate cells and when you need it for surgery they will put on their matrix, enrich, expand and ship out
  • Allogeneic cells: project where take allogeneic neural stem cells to deliver a chemotherapy payload as they like to migrate to brain tumors
  • Allogeneic cells: for ALS modified to express GDNF
  • HIV resistance with engineered CCR5 negative blood stem cells
  • Release assay considerations: viability, sterility, if cryopreserved then can determine identity, viral insertions, VSV-G copy number, endotoxin and potency (FDA is wanting phase I potency assays) for CART potency is % transduced
  • Good in vivo activity of the neural stem cells loaded with chemotherapeutic

 

ALS  

  • If deliver GDNF to muscle  using genetically modified myoblasts
  • Best to use fetal stem cells – less issues

 

Canavan disease: progressive fatal neurologic disorder that begins in infancy and don’t make it past teenage years

  • Rossbach is taking autologous cells reprogramming generating iPS cells and then modifying by CRISPR but the CRISPR issues of off target effects persist as well the time required for process and verification; also don’t want to use a selectable marker and put in patients; so you can differentiate the cells and hit them with a lentiviral vector system

 

They have been named a PACT Center Production Assistance for Cell Therapy where you can apply for a project grant.  Applicable for startups up to larger mature companies

www.pactgroup.net

 

They do a standard panel of tests for viral infections.

They work with investigators or companies at all stages of manufacturing processes.

2:15 Large-Scale Production of Cell Therapies for Regenerative Medicine

Joseph Gold, Ph.D. Director Manufacturing Center for Biomedicine and Genetics, Beckman Research Institute

 

2:45  Directed Evolution of New Viruses for Therapeutic Gene Delivery

David Schaffer, Ph.D.  Professor of Chemical and Biomolecular Engineering, BioEngineering, Molecular and Cell Biology and Neuroscience;

 

AAV is very safe as many people already infected with it

 

  • Spark (Leber’s cogenital anaurosis
  • Hemophilia B
  • Lipoprotein lipase deficiency
  • Spinal muscular atrophy
  • Challenges: are we just getting the ‘low hanging fruit’ eg Spark therapy must be injected after retinal therapy, hemo B needs to be given at high doses
  • Their theory was AAV had been evolving for its own purposes so hence the limitations of AAV;
  • Utilized 25 different techniques to generate variants of AAV in a library then packaged (each will have its own barcode)
  • Broad platform technology: retina, lung, brain and spinal cord

Retinal:  AAV may be too large to get through layers of the eye, problems; subretinal injections and damage or retinal detachment.  Then they used their whole library in an in-vivo screen (as hard to recapitulate the multi cell layers of the retina).  

 

Cystic Fibrosis

  • AAV2H22 variant worked very well to supply the CFTR gene in pig model of cystic fibrosis and increases chloride transport and reduce bacterial load
  • Then found pig variant AAV did not work well on human tissue so designed a human variant and worked well in human tissues
  • The variant AAV2.5T surrounds sialic acid binding pockets and increases binding and endocytosis

 

Brain and Spinal Cord:  Sanfilippo B trial  8 holes drilled into skull followed by 16 AAV injections

 

  • Injected a generated AAV variant (by evolution process) : engineered AAV2 is 100 fold better getting through blood brain barrier… novel variant undergoes retrograde transport to cortex ; made a cas9 to remove a tdTomato gene overexpressed in mouse and found 90% knockdown
  • Also interesting point: the porcine variant did not work in human and the human variant did not work in porcine.  Implication for FDA safety and efficacy testing must do in monkeys

They started a spinout 4D Molecular Therapeutics

 

4:25 Lentiviral Vectors for Gene Therapy

 

Munapaty Swani, Ph.D. Texas Tech Health Science Center

 

  • Can express multiple shRNA under a separate promoter but toxic so if expressed in miRNA backbone could be safer under a pol II
  • How much of flanking sequence is needed?
  • 30 nt flanking sequence is enough for Drosha processing
  • Constructed 1 to 7 shRNA-miR targeting CCR5 and 6 viral genes; all constructs were functional
  • Problem with pol ii promoter
  • These 7 shRNA miRNA protect against HIV entry if against CCR5 and the 7 viral elements
  • Used the non-integrating lentivirus for transient to see if infect T cells or not versus integrating lentivirus ; results non-integrating lentivirus did not infect t cells so safer to use
  • CCR5 disruption reduced HIV infection in T cells in vitro;
  • ZFN treatment of HIV+ PBMC prevents activation of HIV
  • Encapsulted CAS9 within LV; cas9 protein is incorporated within LV and is functional
  • First transduce then come in with the Cas9 so made all in one lentivirus with Cas9 and an sgRNA expression vector *******
  • This shows that it is possible to put all in a nanoparticle based lentivirus and an all in one may make it easier and safer (supposedly)

 

4:55 AAV Capsid Design

Miguel Seria Esteves, PhD Associate Professor Neurology, Gene Therapy Center University of Massachusetts Medical School

 

-AAV replication dependent no known human disease with native AAV

  •  Multiple barriers to get across blood brain barrier
  • AAV9 preferentially target neonatal neurons and adult astrocytes
  • Multiple capsids can be used for AAV9 infection in brain but not complete
  • Can we design better capsids to give it better tropic properties and better penetration to blood brain barrier
  • Using a polyalanine in the 5’ end of the caspid was most efficeint
  • Increases gene transfer efficiency especially IN SELECT CELL TYPES; Glial transduction and increased in striatum: increase is structure specific so little in thalamus but good in cerebellum and spinal cord
  • AAV9 tranduces also in peripheral tissues with or without modified capsid

 

Huntington’s Disease

  • Polyglutamate disease polyy glu on huntingtin protein
  • They get a 40 to 50% reduction of huntingtin but not significant between capsid design
  • They did a directed evolution of AAV capsid and generated capsid gene delivery diversity: DNA shuffling and in vivo selection
  • AAV-B1 is a new tropic capsid showing transduction of different structures
  • Five fold reduction in tropism to the liver but massive increases in muscle and beta exocrine cells and lung
  • Presence of neutralizing antibodies is a problem with AAV therapy
  • In conclusion unknown mechanisms by whivh a highly hydrophobic string of 19 alanines modifies the CHS tropism of AAV9 kvariants
  • Chimeric capsids identified from in vivo screen can reveal interesting patterns of tropism

8:20 AAV for Gene Therapy and Genome Editing

James Wilson, M.D., Ph.D., Professor, Department of Pathology and Laboratory Medicine, Perelman School of Medicine; Director, Orphan Disease Center and Director, Gene Therapy Program, University of Pennsylvania

AAV delivery for CNS can be direct into brain or into CSF but AAV are big and vectors usually don’t cross BBB

Mucopolysaccharidoses a lysosomal storage disease including Hunter, Morquio

  • There are canine models for these diseases
  • Data show that intrathecal delivery has good distribution to the CSF not the serum
  • With IV you only get spinal distribution but IT you get good distribution to cerebellum and frontal cortex
  • Intrathecal superior for clearing lesions in cortex of dogs
  • In the dog the disease is more skeletal and less neurologic so with IT dogs were better than control but still some problems
  • Avaxis: AAV9 gene therapy for SMA and ALS but trials are very small but seems to be dose dependent effect ; phase I/II done; Pfizer, Esteves and REGENEXBIO have trials
  • Liver transduction of AAV has always been a success; early vectors were not efficient for uptake but AAV9 hemophelia B (factor 9) was
  • OCTD disease of urea acid cycle (neonatal versus late onset); proteins altered metabolism
  • Have to create a metabolic sink to detoxify metabolites; not lie a gene replacement therapy
  • They got stable expression in mouse adult  model of OCTD with AAV and had rapid onset of expression; but when done in newborn mice they saw transient expression
  • Newborn liver is proliferating so gene vector may be diluted out versus the adult liver
  • So turned to gene editing (ZFN:NEHJ, TALEN:HR gene correction, CRSPR:transgene addition by HR
  • Staph aureus cas9 is smaller than most and can fit in a 4.79kb vector*****
  • Put in 2.6 kb doner OCTD gRNA
  • With a CRSPR-Cas9 mediated deliverycould maintain the expression of OCTD for over a week in newborn mice
  • BUT in adults the gene corrected animals started to die; they were losing their ability to break down protein
  • In newborns you got 10% gene editing with 30% indels but with adults 30% resulted only in 1% gene editing
  • There is a propensity to create large (>50bp) indels in the adult
  • NGS was needed to fully detect the target transgene integration, PCR is not good enough
  • Says that large animal models are needed for safety/efficacy studies
  • Problem with Rhesus monkey: started with a humanized mouse in Rag mice because did not want to do monkey studies; but did not get good expression in the monkeys (it was not the vector which was the problem)
  • AAV may be good enough of a donor to cause the HR recombination

 

Summary:  AAV vectors combined with a CRSPR CAS9 system is effective in neonatal delivery however 1) AAV by itself may be a good delivery system by itself but need the crsipir guide RNA to make the break to promote HR and get the best efficiency of integration 2) use of CRSPR CAS9 may direct the proper integration you want to deliver the OCTD exons to correct gene loci

9:20 Using CRISPR/Cas9 to Target and Destroy Viral DNA Genomes; Inactivating HBV

 

Bryan R. Cullen, Ph.D., James B. Duke Professor of Molecular Genetics and Microbiology and Director, Center for Virology, Duke University

 

The CRISPR array is an evolutionary record of the bacteriophage that the bacteria have encountered.

  • Incredible that a bacteria that never encountered a chromosomal structure would scan the genome with these gRNAs and then initiate HR and NEHJ (error prone in mammalian cells usually 3 nt
  • HBV is a very confused retrovirus because it first goes into the nucleus then becomes a template for RNA synthesis to make the particles that reinfect the cell and invisible to immune response
  • Although they do not produce infectious virus it still remains in genome
  • sgRNA screening: use a luciferase based assay to correct or knock out luc so looking for decrease of luciferase activity
  • In a model of HBV infection where they have an inducible HBV cccDNA in a single integrated copy the cas9 reduced the DNA but protein was not decreased that much (if you hit episomal DNA you see loss and the disintegration of cut out DNA but if you hit integrated DNA you see repair
  • In their case the integrated DNA was just mutated (A or AA insertion) so in essence a frameshift mutation
  • Future strategies: use two guide RNAs to permit deletions or allow use of nickase. Currently these gRNA use polIII which is very large
  • They are editing the VEGF loci using Sau Cas9 and two sgRNAs
  • In mice with HBV integrated in their genome get some cutting but they need to go to higher doses of Cas9 system
  • Potential future success if reduce viral load as HBV continually release antigen which results in T cell anergy and if reduce the viral load may help to reduce anergy and wake up the immune system

10:35 Targeted Endonucleases as Antiviral Agents: Promises and Pitfalls

Keith R. Jerome, M.D., Ph.D., Member, Vaccine and Infectious Disease Division, Fred Hutchinson Cancer Research Center; Professor and Head, Virology Division, Department of Laboratory Medicine, University of Washington

 

  • Can cure Hepatititis C because can stop replication
  • HSV in neurons and live for life: long lived form like HBV
  • Herpes simplex (HSV) establishes in dorsal root ganglion: acyclovir might be useful but came off patent
  • He reached out to advocacy groups to get data on need for HSV cure to convince funding agencies this is important
  • They found it is important to people; 90% want a cure if 5 years away
  • Homing endonucleases: small 800bp high specificity easy to put in vectors more difficult retargeting to other DNA targets
  • www.ltk.uzh.ch/de/dyn
  • HSV homing endonuclease from Cellectis AG targets a 24bp sequence in Ul19; introduces a DSB at target site with 4 bp 3’ overhang;
  • AAV targeted endonuclease delivery; nonimmunogenic; persists in episomal state
  • Exposure to HSV specific HE decreases virus production from neuronal cultures at all stages of replication cycle; if infect and let go for a month but the HE disrupts HSV in acute late-acute and late cycle
  • Developed a mouse model of HSV infection and AAV delivery in vivo system; so the AAV was accessing the nerve endings and going down to the trigenital dorsal ganglia; transport is independent of AAV serotype but transgene expression is HIGHLY dependent on AAV serotype
  • The in vivo HE treatment appears well tolerated however just a casual observation
  • Used NGS with bioinformatic approach to determine off target sites for the most likely mouse loci
  • HE suppresses viral reactivation (used PCR based reactivation assay)

8:20 AAV for Gene Therapy and Genome Editing

James Wilson, M.D., Ph.D., Professor, Department of Pathology and Laboratory Medicine, Perelman School of Medicine; Director, Orphan Disease Center and Director, Gene Therapy Program, University of Pennsylvania

In vivo delivery of nucleic acid therapeutics remains the primary barrier to success. My lab has focused on the use of vectors based on adeno-associated virus (AAV) for achieving success in pre-clinical and clinical applications of gene replacement therapy. Most of the current academic and commercial applications of in vivo gene replacement therapy are based on endogenous AAVs we discovered as latent viral genomes in primates. These vectors are reasonably safe and efficient for application of gene replacement therapy. The emergence of genome editing methods has suggested more precise and effective methods to treat inherited diseases in which genes are silenced or mutations are corrected. AAV vectors have been the most efficient platform for achieving genome editing in vivo. We will review our attempts to achieve therapeutic genome editing in animal models of liver disease using AAV.

9:20 Using CRISPR/Cas to Target and Destroy Viral DNA Genomes

Bryan R. Cullen, Ph.D., James B. Duke Professor of Molecular Genetics and Microbiology and Director, Center for Virology, Duke University

A number of pathogenic human DNA viruses, including HBV, HIV-1 and HSV1, cause chronic diseases in humans that remain refractory to cure, though these diseases can be controlled by antivirals. In addition the DNA virus HPV causes tumors that depend on the continued expression of viral genes. Here, I will present data demonstrating that several of these viruses can be efficiently cleaved and destroyed using viral vectors that express Cas9 and virus-specific guide RNAs, thus providing a potential novel approach to treatment.

  • HBV – as target intervention
  • CRISPR/Cas9 RNA Guided Nuclease System (RGN)
  • NGG- PAM >> dsDNA cleavage >> NHEJ Repair >> Prfect repair >> Completion Repair Cycle
  • vs Mutagenesis – cycle exit
  1. HBV – Inactivation with CRISPR/Cas9: HBV lifecycle of the virus — reverse transcripatse (RT) of caspid and envelope – release antigens in blood invisible to Immune response, SUrfacce Antigen,COre Antigen, X-protein,
  2. Inhibitors of HBV  – cccDNA is stable for decades – virus in blood do not create new virus
  3. tetracycline represses HBV expression
  4. HBsAG va HBeAG: on core, surface, RT and N.S. sgRNA

Vector Delivery Strategies to the Liver

  • Strep pyogenes Cas9 – a diffrence PAM (5′ – NNGRRT-3′) – too large – ~4.8kb, including th ITRs.
  • Can we identify smaller Promoters
  • Packaging Sau Cas9 and two sgRNAs into AAV

Summary

  • using HBV-infected hepatocytes of a humanized liver or transgenic mouse – HBV Dual Target

Using HBV with RT and CRISPR Cas9 — viral load reduced to awake the immune response – allergy stage  – potential for future therapeutics

11:05 Nucleic Acid Delivery Systems for RNA Therapy and Gene Editing

Daniel Anderson, Ph.D., Professor, Department of Chemical Engineering, Institute for Medical Engineering & Science, Harvard-MIT Division of Health Sciences & Technology and David H. Koch Institute for Integrative Cancer Research, Massachusetts Institute of Technology

High throughput, combinatorial approaches have revolutionized small molecule drug discovery. Here we describe our high throughput methods for developing and characterizing RNA delivery and gene editing systems. Libraries of degradable polymers and lipid-like materials have been synthesized, formulated and screened for their ability to deliver RNA, both in vitro and in vivo. A number of delivery formulations have been developed with in vivo efficacy, and show potential applications for the treatment of genetic diseases, viral infections and cancers.
