In the last couple of years we are witnessing a surge of AI applications in healthcare. It is clear now, that AI and its wide range of health-applications are about to revolutionize diseases’ pathways and the way the variety of stakeholders in this market interact.

Not surprisingly, the developing surge has waken the regulatory watchdogs who are now debating ways to manage the introduction of such applications to healthcare. Attributing measures to known regulatory checkboxes like safety, and efficacy is proving to be a complex exercise. How to align claims made by manufacturers, use cases, users’ expectations and public expectations is unclear. A recent demonstration of that is the so called “failure” of AI in social-network applications like FaceBook and Twitter in handling harmful materials.

‘Advancing AI in the NHS’ – is a report covering the challenges and opportunities of AI in the NHS. It is a modest contribution to the debate in such a timely and fast-moving field!  I bring here the report’s preface and executive summary hoping that whoever is interested in reading the whole 50 pages of it will follow this link: f53ce9_e4e9c4de7f3c446fb1a089615492ba8c

Foreword

Almost every day, as MP for Cambridge, I am told of new innovations and developments that show that we are on the cusp of a technological revolution across the sectors. This technology is capable of revolutionising the way we work; incredible innovations which could increase our accuracy, productivity and efficiency and improve our capacity for creativity and innovation.

But huge change, particularly through adoption of new technology, can be difficult to  communicate to the public, and if we do not make sure that we explain carefully the real benefits of such technologies we easily risk a backlash. Despite good intentions, the care.data programme failed to win public trust, with widespread worries that the appropriate safeguards weren’t in place, and a failure to properly explain potential benefits to patients. It is vital that the checks and balances we put in place are robust enough to sooth public anxiety, and prevent problems which could lead to steps back, rather than forwards.

Previous attempts to introduce digital innovation into the NHS also teach us that cross-disciplinary and cross-sector collaboration is essential. Realising this technological revolution in healthcare will require industry, academia and the NHS to work together and share their expertise to ensure that technical innovations are developed and adopted in ways that prioritise patient health, rather than innovation for its own sake. Alongside this, we must make sure that the NHS workforce whose practice will be altered by AI are on side. Consultation and education are key, and this report details well the skills that will be vital to NHS adoption of AI. Technology is only as good as those who use it, and for this, we must listen to the medical and healthcare professionals who will rightly know best the concerns both of patients and their colleagues. The new Centre for Data Ethics and Innovation, the ICO and the National Data Guardian will be key in working alongside the NHS to create both a regulatory framework and the communications which win society’s trust. With this, and with real leadership from the sector and from politicians, focused on the rights and concerns of individuals, AI can be advanced in the NHS to help keep us all healthy.

Executive summary

Artificial intelligence (AI) has the potential to transform how the NHS delivers care. From enabling patients to self-care and manage long-term conditions, to advancing triage, diagnostics, treatment, research, and resource management, AI can improve patient outcomes and increase efficiency. Achieving this potential, however, requires addressing a number of ethical, social, legal, and technical challenges. This report describes these challenges within the context of healthcare and offers directions forward.

Data governance

AI-assisted healthcare will demand better collection and sharing of health data between NHS, industry and academic stakeholders. This requires a data governance system that ensures ethical management of health data and enables its use for the improvement of healthcare delivery. Data sharing must be supported by patients. The recently launched NHS data opt-out programme is an important starting point, and will require monitoring to ensure that it has the transparency and clarity to avoid exploiting the public’s lack of awareness and understanding. Data sharing must also be streamlined and mutually beneficial. Current NHS data sharing practices are disjointed and difficult to negotiate from both industry and NHS perspectives. This issue is complicated by the increasing integration of ’traditional’ health data with that from commercial apps and wearables. Finding approaches to valuate data, and considering how patients, the NHS and its partners can benefit from data sharing is key to developing a data sharing framework. Finally, data sharing should be underpinned by digital infrastructure that enables cybersecurity and accountability.

Digital infrastructure

Developing and deploying AI-assisted healthcare requires high quantity and quality digital data. This demands effective digitisation of the NHS, especially within secondary care, involving not only the transformation of paper-based records into digital data, but also improvement of quality assurance practices and increased data linkage. Beyond data digitisation, broader IT infrastructure also needs upgrading, including the use of innovations such as wearable technology and interoperability between NHS sectors and institutions. This would not only increase data availability for AI development, but also provide patients with seamless healthcare delivery, putting the NHS at the vanguard of healthcare innovation.

Standards

The recent advances in AI and the surrounding hype has meant that the development of AI-assisted healthcare remains haphazard across the industry, with quality being difficult to determine or varying widely. Without adequate product validation, including in

real-world settings, there is a risk of unexpected or unintended performance, such as sociodemographic biases or errors arising from inappropriate human-AI interaction. There is a need to develop standardised ways to probe training data, to agree upon clinically-relevant performance benchmarks, and to design approaches to enable and evaluate algorithm interpretability for productive human-AI interaction. In all of these areas, standardised does not necessarily mean one-size-fits-all. These issues require addressing the specifics of AI within a healthcare context, with consideration of users’ expertise, their environment, and products’ intended use. This calls for a fundamentally interdisciplinary approach, including experts in AI, medicine, ethics, cognitive science, usability design, and ethnography.

Regulations

Despite the recognition of AI-assisted healthcare products as medical devices, current regulatory efforts by the UK Medicines and Healthcare Products Regulatory Agency and the European Commission have yet to be accompanied by detailed guidelines which address questions concerning AI product classification, validation, and monitoring. This is compounded by the uncertainty surrounding Brexit and the UK’s future relationship with the European Medicines Agency. The absence of regulatory clarity risks compromising patient safety and stalling the development of AI-assisted healthcare. Close working partnerships involving regulators, industry members, healthcare institutions, and independent AI-related bodies (for example, as part of regulatory sandboxes) will be needed to enable innovation while ensuring patient safety.

The workforce

AI will be a tool for the healthcare workforce. Harnessing its utility to improve care requires an expanded workforce with the digital skills necessary for both developing AI capability and for working productively with the technology as it becomes commonplace.

Developing capability for AI will involve finding ways to increase the number of clinician-informaticians who can lead the development, procurement and adoption of AI technology while ensuring that innovation remains tied to the human aspect of healthcare delivery. More broadly, healthcare professionals will need to complement their socio-emotional and cognitive skills with training to appropriately interpret information provided by AI products and communicate it effectively to co-workers and patients.

Although much effort has gone into predicting how many jobs will be affected by AI-driven automation, understanding the impact on the healthcare workforce will require examining how jobs will change, not simply how many will change.

Legal liability

AI-assisted healthcare has implications for the legal liability framework: who should be held responsible in the case of a medical error involving AI? Addressing the question of liability will involve understanding how healthcare professionals’ duty of care will be impacted by use of the technology. This is tied to the lack of training standards for healthcare professionals to safely and effectively work with AI, and to the challenges of algorithm interpretability, with ”black-box” systems forcing healthcare professionals to blindly trust or distrust their output. More broadly, it will be important to examine the legal liability of healthcare professionals, NHS trusts and industry partners, raising questions

Recommendations

  1. The NHS, the Centre for Data Ethics and Innovation, and industry and academic partners should conduct a review to understand the obstacles that the NHS and external organisations face around data sharing. They should also develop health data valuation protocols which consider the perspectives of patients, the NHS, commercial organisations, and academia. This work should inform the development of a data sharing framework.
  2. The National Data Guardian and the Department of Health should monitor the NHS data opt-out programme and its approach to transparency and communication, evaluating how the public understands commercial and non-commercial data use and the handling of data at different levels of anonymisation.
  3. The NHS, patient advocacy groups, and commercial organisations should expand public engagement strategies around data governance, including discussions about the value of health data for improving healthcare; public and private sector interactions in the development of AI-assisted healthcare; and the NHS’s strategies around data anonymisation, accountability, and commercial partnerships. Findings from this work should inform the development of a data sharing framework.
  4. The NHS Digital Security Operations Centre should ensure that all NHS organisations comply with cybersecurity standards, including having up-to-date technology.
  5. NHS Digital, the Centre for Data Ethics and Innovation, and the Alan Turing Institute should develop technological approaches to data privacy, auditing, and accountability that could be implemented in the NHS. This should include learning from Global Digital Exemplar trusts in the UK and from international examples such as Estonia.
  6. The NHS should continue to increase the quantity, quality, and diversity of digital health data across trusts. It should consider targeted projects, in partnership with professional medical bodies, that quality-assure and curate datasets for more deployment-ready AI technology. It should also continue to develop its broader IT infrastructure, focusing on interoperability between sectors, institutions, and technologies, and including the end users as central stakeholders.
  7. The Alan Turing Institute, the Ada Lovelace Institute, and academic and industry partners in medicine and AI should develop ethical frameworks and technological approaches for the validation of training data in the healthcare sector, including methods to minimise performance biases and validate continuously-learning algorithms.
  8. The Alan Turing Institute, the Ada Lovelace Institute, and academic and industry partners in medicine and AI should develop standardised approaches for evaluating product performance in the healthcare sector, with consideration for existing human performance standards and products’ intended use.
  9. The Alan Turing Institute, the Ada Lovelace Institute, and academic and industry partners in medicine and AI should develop methods of enabling and evaluating algorithm interpretability in the healthcare sector. This work should involve experts in AI, medicine, ethics, usability design, cognitive science, and ethnography, among others.
  10. Developers of AI products and NHS Commissioners should ensure that usability design remains a top priority in their respective development and procurement of AI-assisted healthcare products.
  11. The Medicines and Healthcare Products Regulatory Agency should establish a digital health unit with expertise in AI and digital products that will work together with manufacturers, healthcare bodies, notified bodies, AI-related organisations, and international forums to advance clear regulatory approaches and guidelines around AI product classification, validation, and monitoring. This should address issues including training data and biases, performance evaluation, algorithm interpretability, and usability.
  12. The Medicines and Healthcare Products Regulatory Agency, the Centre for Data Ethics and Innovation, and industry partners should evaluate regulatory approaches, such as regulatory sandboxing, that can foster innovation in AI-assisted healthcare, ensure patient safety, and inform on-going regulatory development.
  13. The NHS should expand innovation acceleration programmes that bridge healthcare and industry partners, with a focus on increasing validation of AI products in real-world contexts and informing the development of a regulatory framework.
  14. The Medicines and Healthcare Products Regulatory Agency and other Government bodies should arrange a post-Brexit agreement ensuring that UK regulations of medical devices, including AI-assisted healthcare, are aligned as closely as possible to the European framework and that the UK can continue to help shape Europe-wide regulations around this technology.
  15. The General Medical Council, the Medical Royal Colleges, Health Education England, and AI-related bodies should partner with industry and academia on comprehensive examinations of the healthcare sector to assess which, when, and how jobs will be impacted by AI, including analyses of the current strengths, limitations, and workflows of healthcare professionals and broader NHS staff. They should also examine how AI-driven workforce changes will impact patient outcomes.
  16. The Federation of Informatics Professionals and the Faculty of Clinical Informatics should continue to lead and expand standards for health informatics competencies, integrating the relevant aspects of AI into their training, accreditation, and professional development programmes for clinician-informaticians and related professions.
  17. Health Education England should expand training programmes to advance digital and AI-related skills among healthcare professionals. Competency standards for working with AI should be identified for each role and established in accordance with professional registration bodies such as the General Medical Council. Training programmes should ensure that ”un-automatable” socio-emotional and cognitive skills remain an important focus.
  18. The NHS Digital Academy should expand recruitment and training efforts to increase the number of Chief Clinical Information Officers across the NHS, and ensure that the latest AI ethics, standards, and innovations are embedded in their training programme.
  19. Legal experts, ethicists, AI-related bodies, professional medical bodies, and industry should review the implications of AI-assisted healthcare for legal liability. This includes understanding how healthcare professionals’ duty of care will be affected, the role of workforce training and product validation standards, and the potential role of NHS Indemnity and no-fault compensation systems.
  20. AI-related bodies such as the Ada Lovelace Institute, patient advocacy groups and other healthcare stakeholders should lead a public engagement and dialogue strategy to understand the public’s views on liability for AI-assisted healthcare.

That is the question…

Anyone who follows healthcare news, as I do , cannot help being impressed with the number of scientific and non-scientific items that mention the applicability of Magnetic Resonance Imaging (‘MRI’) to medical procedures.

A very important aspect that is worthwhile noting is that the promise MRI bears to improve patients’ screening – pre-clinical diagnosis, better treatment choice, treatment guidance and outcome follow-up – is based on new techniques that enables MRI-based tissue characterisation.

Magnetic resonance imaging (MRI) is an imaging device that relies on the well-known physical phenomena named “Nuclear Magnetic Resonance”. It so happens that, due to its short relaxation time, the 1H isotope (spin ½ nucleus) has a very distinctive response to changes in the surrounding magnetic field. This serves MRI imaging of the human body well as, basically, we are 90% water. The MRI device makes use of strong magnetic fields changing at radio frequency to produce cross-sectional images of organs and internal structures in the body. Because the signal detected by an MRI machine varies depending on the water content and local magnetic properties of a particular area of the body, different tissues or substances can be distinguished from one another in the scan’s resulting image.

The main advantages of MRI in comparison to X-ray-based devices such as CT scanners and mammography systems are that the energy it uses is non-ionizing and it can differentiate soft tissues very well based on differences in their water content.

In the last decade, the basic imaging capabilities of MRI have been augmented for the purpose of cancer patient management, by using magnetically active materials (called contrast agents) and adding functional measurements such as tissue temperature to show internal structures or abnormalities more clearly.

 

In order to increase the specificity and sensitivity of MRI imaging in cancer detection, various imaging strategies have been developed. The most discussed in MRI related literature are:

  • T2 weighted imaging: The measured response of the 1H isotope in a resolution cell of a T2-weighted image is related to the extent of random tumbling and the rotational motion of the water molecules within that resolution cell. The faster the rotation of the water molecule, the higher the measured value of the T2 weighted response in that resolution cell. For example, prostate cancer is characterized by a low T2 response relative to the values typical to normal prostatic tissue [5].

  • Dynamic Contrast Enhanced (DCE) MRI involves a series of rapid MRI scans in the presence of a contrast agent. In the case of scanning the prostate, the most commonly used material is gadolinium [4].

  • Diffusion weighted (DW) imaging: Provides an image intensity that is related to the microscopic motion of water molecules [5].

DW image of the left parietal glioblastoma multiforme (WHO grade IV) in a 59-year-old woman, Al-Okaili R N et al. Radiographics 2006;26:S173-S189

  • Multifunctional MRI: MRI image overlaid with combined information from T2-weighted scans, dynamic contrast-enhancement (DCE), and diffusion weighting (DW) [5].

Source AJR: http://www.ajronline.org/content/196/6/W715/F3

  • Blood oxygen level-dependent (BOLD) MRI: Assessing tissue oxygenation. Tumors are characterized by a higher density of micro blood vessels. The images that are acquired follow changes in the concentration of paramagnetic deoxyhaemoglobin [5].

In the last couple of years, medical opinion leaders are offering to use MRI to solve almost every weakness of the cancer patients’ pathway. Such proposals are not always supported by any evidence of feasibility. For example, a couple of weeks ago, the British Medical Journal published a study [1] concluding that women carrying a mutation in the BRCA1 or BRCA2 genes who have undergone a mammogram or chest x-ray before the age of 30 are more likely to develop breast cancer than those who carry the gene mutation but who have not been exposed to mammography. What is published over the internet and media to patients and lay medical practitioners is: “The results of this study support the use of non-ionising radiation imaging techniques (such as magnetic resonance imaging) as the main tool for surveillance in young women with BRCA1/2 mutations.”.

Why is ultrasound not mentioned as a potential “non-ionising radiation imaging technique”?

Another illustration is the following advert:

An MRI scan takes between 30 to 45 minutes to perform (not including the time of waiting for the interpretation by the radiologist). It requires the support of around 4 well-trained team members. It costs between $400 and $3500 (depending on the scan).

The important question, therefore, is: Are there, in the USA, enough MRI  systems to meet the demand of 40 million scans a year addressing women with radiographically dense  breasts? Toda there are approximately 10,000 MRI systems in the USA. Only a small percentage (~2%) of the examinations are related to breast cancer. A

A rough calculation reveals that around 10000 additional MRI centers would need to be financed and operated to meet that demand alone.

FDA chief Scott Gottlieb steps down, leaving pet projects behind

Scott Gottlieb FDA
FDA Commissioner Scott Gottlieb was appointed by President Trump in 2017. (FDA)

Also under his command, the FDA took quick and decisive action on drug costs. The commissioner worked to boost generic approvals and crack down on regulatory “gaming” that stifles competition. He additionally blamed branded drug companies for an “anemic” U.S. biosimilars market and recently blasted insulin pricing.

His sudden departure will likely leave many agency efforts to lower costs up in the air. After the news broke, many pharma watchers posted on Twitter that Gottlieb’s resignation is a loss for the industry.

During his tenure as FDA commissioner, Gottlieb’s name had been floated for HHS chief when former HHS secretary Tom Price resigned due to a travel scandal, but Gottlieb said he was best suited for the FDA commissioner job. Now, former Eli Lilly executive Alex Azar serves as HHS secretary, and on Tuesday afternoon, Azar praised Gottlieb for his work at the agency.

WASHINGTON — Dr. Norman E. (Ned) Sharpless, director of the National Cancer Institute, will serve as acting commissioner of the Food and Drug Administration, Alex M. Azar III, secretary of health and human services, announced on Tuesday.

Dr. Sharpless temporarily will fill the post being vacated by Dr. Scott Gottlieb, who stunned public health experts, lawmakers and consumer groups last week when he abruptly announced that he was resigningfor personal reasons.

Dr. Sharpless has been director of the cancer center, part of the National Institutes of Health, since October 2017. He is also chief of the aging biology and cancer section in the National Institute on Aging’s Laboratory of Genetics and Genomics. His research focuses on the relationship between aging and cancer, and development of new treatments for melanoma, lung cancer and breast cancer.

“Dr. Sharpless’s deep scientific background and expertise will make him a strong leader for F.D.A.,” said Mr. Azar, in a statement. “There will be no let up in the agency’s focus, from ongoing efforts on drug approvals and combating the opioid crisis to modernizing food safety and addressing the rapid rise in youth use of e-cigarettes.”

Dr. Douglas Lowy, known for seminal research on the link between human papillomavirus and multiple cancer types including cervical, and ultimately leading to development of a vaccine, will be named head of the NCI to replace Dr. Sharpless. Dr. Lowy currently is Deputy Director of the NCI.

FDA Approves La Jolla’s Angiotensin 2

Reporter: Irina Robu, PhD

In La Jolla Pharmaceutical Company’s new drug application (NDA) for angiotensin 2, the treatment was given priority review status by the FDA, advancing the application process to 6 months. The US Food and Drug Administration has approved an IV agent to treat critically-low blood pressure angiotensin 2 injection (Giapreza) for the treatment of adults with septic or other distributive shock. The intravenous infusion therapy is considered to increase blood pressure in adult patients with hypotension. The condition can cause shock in which the brain, kidneys, and other vital organs are no longer getting the appropriate amount of blood flow to function correctly.

The trial was based on the 321-patient ATHOS-3 trial, in which 69.9% of patients with catecholamine-resistant hypotension treated with angiotensin II upgrading at hour 3 versus 23.4% with placebo. The exploratory therapy was run in combination with conventional treatments used to raise patients’ blood pressure. The treatment was revealed an increase blood pressure, reported safety and tolerability.

Even though the label indicates that the drug can cause thrombosis, concurrent prophylactic treatment should be used. In ATHOS-3, the incidence of arterial and venous thrombotic events was 13%, compared with 5% in the placebo group, mainly driven by deep vein thrombosis.

John A. Kellum, Director of Center for Critical Care Nephrology, University of Pittsburgh, said the treatment is now an additional tool for the critical care community.

37th Annual J.P. Morgan HEALTHCARE CONFERENCE: News at #JPM2019 for Jan. 10, 2019: Deals and Announcements

Reporter: Stephen J. Williams, Ph.D.

From Biospace.com

 

JP Morgan Healthcare Conference Update: Sage, Mersana, Shutdown Woes and Babies

Speaker presenting to audience at a conference

With the J.P. Morgan Healthcare Conference winding down, companies remain busy striking deals and informing investors about pipeline advances. BioSpace snagged some of the interesting news bits to come out of the conference from Wednesday.

SAGE Therapeutics – Following a positive Phase III report that its postpartum depression treatment candidate SAGE-217 hit the mark in its late-stage clinical trial, Sage Therapeutics is eying the potential to have multiple treatment options available for patients. At the start of J.P. Morgan, Sage said that patients treated with SAGE-217 had a statistically significant improvement of 17.8 points in the Hamilton Rating Scale for Depression, compared to 13.6 for placebo. The company plans to seek approval for SAGE-2017, but before that, the FDA is expected to make a decision on Zulresso in March. Zulresso already passed muster from advisory committees in November, and if approved, would be the first drug specifically for postpartum depression. In an interview with the Business Journal, Chief Business Officer Mike Cloonan said the company believes there is room in the market for both medications, particularly since the medications address different patient populations.

 

Mersana Therapeutics – After a breakup with Takeda Pharmaceutical and the shelving of its lead product, Cambridge, Mass.-based Mersana is making a new path. Even though a partial clinical hold was lifted following the death of a patient the company opted to shelve development of XMT-1522. During a presentation at JPM, CEO Anna Protopapas noted that many other companies are developing therapies that target the HER2 protein, which led to the decision, according to the Boston Business Journal. Protopapas said the HER2 space is highly competitive and now the company will focus on its other asset, XMT-1536, an ADC targeting NaPi2b, an antigen highly expressed in the majority of non-squamous NSCLC and epithelial ovarian cancer. XMT-1536 is currently in Phase 1 clinical trials for NaPi2b-expressing cancers, including ovarian cancer, non-small cell lung cancer and other cancers. Data on XMT-1536 is expected in the first half of 2019.

Novavax – During a JPM presentation, Stan Erck, CEO of Novavax, pointed to the company’s RSV vaccine, which is in late-stage development. The vaccine is being developed for the mother, in order to protect an infant. The mother transfers the antibodies to the infant, which will provide the baby with protection from RSV in its first six months. Erck called the program historic. He said the Phase III program is in its fourth year and the company has vaccinated 4,636 women. He said they are tracking the women and the babies. Researchers call the mothers every week through the first six months of the baby’s life to acquire data. Erck said the company anticipates announcing trial data this quarter. If approved, Erck said the market for the vaccine could be a significant revenue driver.

“You have 3.9 million birth cohorts and we expect 80 percent to 90 percent of those mothers to be vaccinated as a pediatric vaccine and in the U.S. the market rate is somewhere between $750 million and a $1 billion and then double that for worldwide market. So it’s a large market and we will be first to market in this,” Erck said, according to a transcript of the presentation.

Denali Therapeutics – Denali forged a collaboration with Germany-based SIRION Biotech to develop gene therapies for central nervous disorders. The two companies plan to develop adeno-associated virus (AAV) vectors to enable therapeutics to cross the blood-brain barrier for clinical applications in neurodegenerative diseases including Parkinson’s, Alzheimer’s disease, ALS and certain other diseases of the CNS.

AstraZeneca – Pharma giant AstraZeneca reported that in 2019 net prices on average across the portfolio will decrease versus 2018. With a backdrop of intense public and government scrutiny over pricing, Market Access head Rick Suarez said the company is increasing its pricing transparency. Additionally, he said the company is looking at new ways to price drugs, such as value-based reimbursement agreements with payers, Pink Sheet reported.

Amarin Corporation – As the company eyes a potential label expansion approval for its cardiovascular disease treatment Vascepa, Amarin Corporation has been proactively hiring hundreds of sales reps. In the fourth quarter, the company hired 265 new sales reps, giving the company a sales team of more than 400, CEO John Thero said. Thero noted that is a label expansion is granted by the FDA, “revenues will increase at least 50 percent over what we did in the prior year, which would give us revenues of approximate $350 million in 2019.”

Government Woes – As the partial government shutdown in the United States continues into its third week, biotech leaders at JPM raised concern as the FDA’s carryover funds are dwindling. With no new funding coming in, reviews of New Drug Applications won’t be able to continue past February, Pink Sheet said. While reviews are currently ongoing, no New Drug Applications are being accepted by the FDA at this time. With the halt of NDA applications, that has also caused some companies to delay plans for an initial public offering. It’s hard to raise potential investor excitement without the regulatory support of a potential drug approval. During a panel discussion, Jonathan Leff, a partner at Deerfield Management, noted that the ongoing government shutdown is a reminder of how “overwhelmingly dependent the whole industry of biotech and drug development is on government,” Pink Sheet said.

CALD Gene Therapy Granted “Breakthrough Therapy Designation”

Reporter: Irina Robu, PhD

Bluebird Bio’s Lenti D has been granted as “breakthrough therapy designation” by FDA for the treatment of patients with cerebral adrenoleukodystrophy (CALD), or Lorenzo’s Oil disease due to optimistic data from current ongoing Phase 2/3 study. This therapy contains using patient’s own immature bone marrow cells and modifying them to include a functional copy of ABCD1 gene which permits the expression of functional ALD, the deficient protein in the patient population.

In addition, the data indicated that the safety profile of Lenti-D remains consistent with myeloablative chemotherapy and no graft versus host disease or treatment related mortality were reported. Initial findings from the ongoing Starbeam Study (ALD-102) assessing the investigational gene therapy in boys with CALD aged 17 years or younger who do not have a matched sibling donor were published in the New England Journal of Medicine  in October 2017 and indicated that the drug hit its main effectiveness endpoint. In the study, 88% (n=15) of patients infused with Lenti-D remained alive and free of major functional disabilities at 2 years post-treatment.

According to Mohammed Asmal, Vice President, Clinical Development at bluebird bio “The mechanism by which this would work is very much like how stem cell therapy transplantation is able to correct the disease. The theory was certainly there, it just relied on someone, essentially, being willing to develop the vector and then try it on patients who did not have any other feasible options for transplant, and who had poor predicted outcomes for transplant survival.”

Currently, the only available therapeutic option for patients with CALD is allogeneic hematopoietic stem cell transplant (HSCT). Whereas clinical benefit has been reported if made early during CALD progression, possible complications of allogeneic HSCT can be fatal. According to David Davison, chief medical officer at Bluebird Bio “FDA’s Breakthrough Therapy designation for Lenti-D brings new hope to the patients and families affected by this devastating disease”.
