Quantum Leap Healthcare Collaborative Initiates Landmark Phase 2 RECAST DCIS Platform Trial to Evaluate Alternative DCIS Treatments with Atossa Therapeutics, Havah Therapeutics, and the Menarini Group
SAN FRANCISCO, Oct. 30, 2023 /PRNewswire/ -- Quantum Leap Healthcare Collaborative (QLHC) announces the enrollment launch for the Re-Evaluating Conditions for Active Surveillance Suitability as Treatment: Ductal Carcinoma In Situ (RECAST DCIS), a Phase 2 platform study aimed at preventing the progression of DCIS to breast cancer. The study is evaluating three investigational endocrine therapy arms: (Z)-endoxifen, a selective estrogen receptor modulator (SERM) in development by Atossa Therapeutics (Nasdaq: ATOS); HAVAH T+Ai™, a proprietary combination of testosterone (T) and anastrozole (Ai) that targets the androgen and estrogen receptor pathways in development by Havah Therapeutics; and ORSERDU® (elacestrant), the only FDA approved oral selective estrogen receptor degrader (oSERD) in development by Stemline Therapeutics Inc. (Stemline), a wholly-owned subsidiary of the Menarini Group.
- Surgery is the current standard treatment for DCIS even though many patients never progress to breast cancer, which means that patients are often over-treated with invasive procedures.
- A key element in reducing overtreatment of DCIS is identifying biomarkers that reflect the risk of progression so that those with low-risk lesions are spared surgery.
- RECAST DCIS features the assessment of imaging and molecular-based biomarkers in addition to evaluating new investigational agents in this setting.
- The three collaborators for this trial, Atossa Therapeutics, Havah Therapeutics, and Stemline, all aim to find alternative solutions for DCIS patients and are providing different agents for assessment.
