Strata Oncology, Inc. a next-generation precision oncology company enabling smarter and earlier cancer treatment, today announced expansion of its clinical collaboration with Pfizer (NYSE: PFE) in the Strata Precision Indications for Approved THerapies (Strata PATH^TM) trial. Strata PATH is a prospective pan-tumor therapeutic trial designed to evaluate the efficacy and safety of multiple FDA-approved cancer therapies in new, biomarker-guided patient populations. Pfizer will provide Braftovi^® (encorafenib), Mektovi^®(binimetinib), and Lorbrena^® (lorlatinib) for up to six new cohorts of patients with early-stage lung, melanoma, colorectal, and other cancers who have evidence of micrometastatic disease after initial treatment. Pfizer is already providing Strata with Braftovi^® (encorafenib), Mektovi^® (binimetinib), Lorbrena^® (lorlatinib), Talzenna^®(talazoparib), and Inlyta (axitinib) for evaluation in four late-stage cohorts of the Strata PATH trial.

“The new cohorts of Strata PATH, supported by Pfizer, afford us a very exciting opportunity to move the advances we’ve seen in late-stage cancer into earlier stages of the disease,” said Dan Rhodes, Ph.D., co-founder and Chief Executive Officer, Strata Oncology. “Our goal is to deliver smarter and earlier treatment to every patient and having the support of Pfizer is a testament to the potential of the clinical trials that we are using to accelerate the impact of precision oncology.”

Many of the patients for the new micrometastatic cohorts of Strata PATH will be identified through the Strata Sentinel^TM trial, a 100,000-patient, prospective, observational, pan-solid tumor study of Strata Oncology’s highly sensitive, tumor-informed circulating tumor DNA (ctDNA)-based MRD test. An advanced molecular therapy selection profile is created simultaneously for every patient assessed with the MRD test. This enables rapid identification of clinical trial opportunities, including Strata PATH, for patients who are positive for ctDNA.
