CytoDyn Announces Completion of FDA Meeting on Phase II Study of Leronlimab in Patients with Relapsed/Refractory Microsatellite Stable Colorectal Cancer
VANCOUVER, Washington, Aug. 12, 2024 (GLOBE NEWSWIRE) -- CytoDyn Inc. (OTCQB: CYDY) ("CytoDyn" or the "Company"), a biotechnology company developing leronlimab, a CCR5 antagonist with the potential for multiple therapeutic indications, announced today that it completed a meeting with the U.S. Food and Drug Administration (FDA) to gain alignment on the rationale and proposed dosing for the Company’s Phase II study that will investigate the preliminary safety and activity of leronlimab in combination with trifluridine plus tipiracil (TAS-102) and bevacizumab in participants with CCR5+, microsatellite stable (MSS), relapsed or refractory metastatic colorectal cancer (mCRC).
The Company intends to proceed with a submission of its final study protocol to the FDA, formal engagement of a clinical research organization (CRO), and related preparatory work towards initiating the proposed trial.
This open label, randomized (1:1), multicenter trial will evaluate the anti-tumor activity (via overall response rate, ORR) of leronlimab at doses of 350 mg and 700 mg in combination TAS-102 and bevacizumab in approximately 60 patients with CCR5+, microsatellite stable metastatic CRC (mCRC).
Patients enrolled in the trial must have measurable disease per RECIST v1.1 and have received prior treatment with fluoropyrimidine‐, oxaliplatin‐, and irinotecan‐based chemotherapy, an anti‐VEGF therapy, and, if RAS wild‐type and medically appropriate, an anti-EGFR therapy. CCR5 tumor expression will be determined by immunohistochemistry assay (IHC) and diagnosis of MSS CRC will be confirmed by IHC or next-generation sequencing (NGS).
TAS-102 and bevacizumab will be administered for three of four weeks in a four-week cycle, and leronlimab (at doses of 350 mg or 700 mg) will be administered weekly. The study will include a safety lead-in treating five patients in the 350 mg leronlimab arm prior to beginning enrollment to the 700 mg leronlimab arm.
“We are pleased to have received the FDA’s feedback on our Phase II study of leronlimab in patients with relapsed/refractory microsatellite stable colorectal cancer, and remain on track to commence our oncology trial in the coming months. Advancing leronlimab in the oncology indication has been an important priority for our team as we progress CytoDyn’s clinical pipeline,” said Dr. Jacob Lalezari, CEO.
