Agendia’s MammaPrint® First and Only Genomic Assay to Receive Level 1A Clinical Utility Evidence for Chemotherapy Benefit in Early Breast Cancer Patients

http://www.b3cnewswire.com/201604191373/agendias-mammaprintr-first-and-only-genomic-assay-to-receive-level-1a-clinical-utility-evidence-for-chemotherapy-benefit-in-early-breast-cancer-patients.

  • Clinical high-risk patients with a low-risk MammaPrint® result, including 48 percent node-positive, had five-year distant metastasis-free survival rate in excess of 94 percent, whether randomized to receive adjuvant chemotherapy or not
  • MammaPrint could change clinical practice by substantially de-escalating the use of adjuvant chemotherapy and sparing many patients an aggressive treatment they will not benefit from
  • Forty-six percent overall reduction in chemotherapy prescription among clinically high-risk patients

April 19, 2016 / B3C newswire / Agendia, Inc., together with the European Organisation for Research and Treatment of Cancer (EORTC) and Breast International Group (BIG), announced results from the initial analysis of the primary objective of the Microarray In Node-negative (and 1 to 3 positive lymph node) Disease may Avoid ChemoTherapy (MINDACT) study at the American Association for Cancer Research Annual Meeting 2016 in New Orleans, LA.

Using the company’s MammaPrint® assay, patients with early-stage breast cancer who were considered at high risk for disease recurrence based on clinical and biological criteria had a distant metastasis-free survival at five years in excess of 94 percent.The MammaPrint test—the first and only genomic assay with FDA 510(k) clearance for use in risk assessment for women of all ages with early stage breast cancer—identified a large group of patients for whom five-year distant metastasis–free survival was equally good whether or not they received adjuvant chemotherapy (chemotherapy given post-surgery).

“The MINDACT trial design is the optimal way to prove clinical utility of a genomic assay,” said Prof. Laura van ’t Veer, CRO at Agendia, Leader, Breast Oncology Program, and Director, Applied Genomics at UCSF Helen Diller Family Comprehensive Cancer Center. “It gives the level 1A clinical evidence (prospective, randomized and controlled) that empowers physicians to clearly and confidently know when chemotherapy is part of optimal early-stage breast cancer therapy.  In this trial, MammaPrint (70-gene assay) was compared to the standard of care physicians use today, to decide what is the best treatment option for an early-stage breast cancer patient.”

The MINDACT trial is the first prospective randomized controlled clinical trial of a breast cancer recurrence genomic assay with level 1A clinical evidence and the first prospective translational research study of this magnitude in breast cancer to report the results of its primary objective.

Among the 3,356 patients enrolled in the MINDACT trial, who were categorized as having a high risk of breast cancer recurrence based on common clinical and pathological criteria (C-high), the MammaPrint assay reduced the chemotherapy treatment prescription by 46 percent.Using the 70-gene assay, MammaPrint, 48 percent of lymph-node positive breast cancer patients considered clinically high-risk (Clinical-high) and genomic low-risk (MammaPrint-low) had an excellent distant metastasis-free survival at five years in excess of 94 percent.

“Traditionally, physicians have relied on clinical-pathological factors such as age, tumor size, tumor grade, lymph node involvement, and hormone receptor status to make breast cancer treatment decisions,” said Massimo Cristofanilli, MD, Associate Director of Translational Research and Precision Medicine at the Robert H. Lurie Comprehensive Cancer Center, Northwestern University in Chicago. “These findings provide level 1A clinical utility evidence by demonstrating that the detection of low-risk of distant recurrence reported by the MammaPrint test can be safely used in the management of thousands of women by identifying those who can be spared from a toxic and unnecessary treatment.”

MINDACT is a randomized phase III trial that investigates the clinical utility of MammaPrint, when compared (or – “used in conjunction with”) to the standard clinical pathological criteria, for the selection of patients unlikely to benefit from adjuvant chemotherapy. From 2007 to 2011, 6,693 women who had undergone surgery for early-stage breast cancer enrolled in the trial (111 centers in nine countries). Participants were categorized as low or high risk for tumor recurrence in two ways: first, through analysis of tumor tissue using MammaPrint at a central location in Amsterdam; and second, using Adjuvant! Online, a tool that calculates risk of breast cancer recurrence based on common clinical and biological criteria.

Patients characterized in both clinical and genomic assessments as “low- risk” are spared chemotherapy, while patients characterized as “high- risk” are advised chemotherapy. Those with conflicting results are randomized to use either clinical or genomic risk (MammaPrint) evaluation to decide on chemotherapy treatment.

The MINDACT trial is managed and sponsored by the EORTC as part of an extensive and complex partnership in collaboration with Agendia and BIG, and many other academic and commercial partners, as well as patient advocates.

“These MINDACT trial results are a testament that the science of the MammaPrint test is the most robust in the genomic breast recurrence assay market.  Agendia will continue to collaborate with pharmaceutical companies, leading cancer centers and academic groups on additional clinical research and in the pursuit of bringing more effective, individualized treatments within reach of cancer patients,” said Mark Straley, Chief Executive Officer at Agendia. “We value the partnership with the EORTC and BIG and it’s a great honor to share this critical milestone.”

Breast cancer is the most frequently diagnosed cancer in women worldwide(1). In 2012, there were nearly 1.7 million new breast cancer cases among women worldwide, accounting for 25 percent of all new cancer cases in women(2).

SAN FRANCISCO — What briefly appeared to be a potential bidding war for Affymetrix, a genetics analysis technology maker, fizzled out on Monday after the company chose to stick with a takeover bid from Thermo Fisher Scientific over a higher bid from a Chinese-backed suitor.

In a statement, Affymetrix reiterated its support for the $14-a-share offer from Thermo Fisher that it accepted in January.

Affymetrix Postpones Stockholder Meeting as Origin Ups Acquisition Offer; Board Backs Thermo Bid

Former Affymetrix Execs Offer to Buy Company in Alternative to Thermo Fisher Deal

NEW YORK (GenomeWeb) – Origin Technologies Corporation, founded by former Affymetrix executives for the purpose of purchasing the company, proposed today to acquire Affy for $16.10 per share in an all-cash transaction valued at approximately $1.5 billion.

The proposal comes about a week before Affy shareholders are scheduled to vote on a different deal, Thermo Fisher Scientific’s proposed acquisition of Affy for approximately $1.3 billion, which the boards of directors of both firms unanimously approved in January.

According to a letter sent by Origin to Affymetrix today, its proposal represents a 75 percent premium to Affymetrix’s unaffected closing share price of $9.21 on the last trading day prior to the announcement of Thermo Fisher’s proposed acquisition.

Fully financed by SummitView Capital, Origin said its all-cash offer represents a 15 percent premium for Affy stockholders relative to the proposed transaction with Thermo, under which stockholders would receive $14.00 per share in cash.

As part of the offer, Origin also pledged to fund payment of the $55 million termination fee that would be due to Thermo under the terms of Thermo and Affy’s January agreement.

Wei Zhou, president of the newly formed Origin, wrote in the letter to Affy today that Origin strongly believes that its offer is superior to Thermo’s based on several criteria.

First, it offers substantially higher value to Affy’s stockholders, he said. Additionally, Origin believes it is in a better position to help Affy achieve its potential as a standalone, global company focused on genomics and proteomics. The deal would also offer an opportunity to acquire new technologies in the complete human genome sequencing space, Zhou wrote.

If the Origin-Affy merger goes through, Origin would have a separate option of combining with another company founded by Zhou in 2009, Centrillion Technology Holdings Corporation.
