Phase 3 Trial for Patients with Severe-to-Critical COVID-19 Symptoms Reaches Enrollment Halfway Point

Germantown, MD, USA (August 26, 2020) – Amarex Clinical Research, LLC, an NSF International company, announced today their client’s Phase 3 clinical trial for patients with severe-to-critical COVID-19 symptoms has reached the patient enrollment halfway point. Preceding follow-up, Amarex’s statistics team will conduct the interim analysis (IA). Results from the IA are expected by mid-October.

This clinical trial investigates CytoDyn’s product leronlimab (PRO 140), a monoclonal antibody product currently undergoing tests as an IND in the treatment of multiple disease indications, including HIV/AIDS, cancer, and GVHD.

Amarex’s President & CEO, Dr. Kazem Kazempour, stated, “Our staff is working hard to expedite COVID-19 clinical trials to make treatments widely available to patients. Early last week we completed a Phase 2 trial of PRO 140 in patients with mild-to-moderate documented COVID-19 symptoms and we are encouraged by the study results. We are also working with CytoDyn to submit an IND for a Phase 3 trial of PRO 140 in long-hauler COVID-19 patients. Amarex has provided, and will continue to provide, clinical trial managements services.”

About CytoDyn Inc.

CytoDyn Inc. is a biotechnology company developing innovative treatments for multiple therapeutic indications based on leronlimab, a novel humanized monoclonal antibody targeting the CCR5 receptor. CCR5 appears to play a key role in the ability of HIV to enter and infect healthy T-cells. The CCR5 receptor also appears to be implicated in tumor metastasis and in immune-mediated illnesses, such as GvHD and NASH. CytoDyn has successfully completed a Phase 3 pivotal trial with leronlimab in combination with standard anti-retroviral therapies in HIV-infected treatment-experienced patients. CytoDyn plans to seek FDA approval for leronlimab in combination therapy and plans to complete the filing of a Biologics License Application (BLA) in the first quarter of 2020 for that indication. CytoDyn is also conducting a Phase 3 investigative trial with leronlimab as a once-weekly monotherapy for HIV-infected patients and plans to initiate a registration-directed study of leronlimab monotherapy indication, which if successful, could support a label extension. Clinical results to date from multiple trials have shown that leronlimab can significantly reduce viral burden in people infected with HIV with no reported drug-related serious adverse events (SAEs). Moreover, results from a Phase 2b clinical trial demonstrated that leronlimab monotherapy can prevent viral escape in HIV-infected patients, with some patients on leronlimab monotherapy remaining virally suppressed for more than five years. CytoDyn is also conducting a Phase 2 trial to evaluate leronlimab for the prevention of GvHD and a Phase 1b/2 clinical trial with leronlimab in metastatic triple-negative breast cancer.
