CytoDyn Announces Stunning Results from Clinical Trials Evaluating mTNBC and MBC with Leronlimab and will Request an Emergency Type C Meeting with FDA to Enroll 50 Awaiting Patients with a Serious Solid Tumor Cancer Condition
Third patient data supports leronlimab (PRO 140) as a potential treatment option for metastatic triple-negative breast cancer (mTNBC) and metastatic breast cancer (MBC). Patient CTC dropped to zero after 2 weeks of leronlimab treatment, same as the first patient on leronlimab
VANCOUVER, Washington, Jan. 31, 2020 (GLOBE NEWSWIRE) -- CytoDyn Inc. (OTC.QB: CYDY), (“CytoDyn” or the “Company"), a late-stage biotechnology company developing leronlimab (PRO
140), a CCR5 antagonist with the potential for multiple therapeutic indications, announced today very strong data from patients in its clinical trials with metastatic triple-negative breast cancer
(mTNBC) and metastatic breast cancer (MBC).
New data from the first patient enrolled in the Company’s mTNBC Phase 1b/2 trial showed no detectable levels of circulating tumor cells (CTC) with leronlimab in combination with carboplatin at 16 weeks of treatment. In addition, this patient experienced significant reductions in epithelial-mesenchymal transition (EMT) cells dropping to zero after five weeks with treatment and currently reports zero EMT. New data from the second patient enrolled in the Company’s mTNBC Phase 1b/2 trial showed no detectable levels of CTC with leronlimab in combination with carboplatin after two weeks of treatment. This patient also showed a 70% reduction in EMT cells after just two weeks of treatment. Initial data from the third patient in the mTNBC trial indicated the CTC dropped to zero after two weeks of treatment with leronlimab.
“Remarkably, the new patient enrolled in the clinical trial showed a significant drop in CTC and a reduction of EMT cells, the putative metastatic cells from 7 per 4mL of blood to two cells in just two weeks of treatment with leronlimab in combination with carboplatin,” said Bruce Patterson, M.D., chief executive officer and founder of IncellDx, a diagnostic partner and an advisor to CytoDyn. “The rapid response to the treatment in a pattern that is identical to previous patients is equally as remarkable and supports a predictable method of action for this drug. Additionally, no adverse effects were observed in the clinical trials, further supporting leronlimab’s potential safety profile.”
