Interim efficacy analysis of primary endpoint to be conducted in coming weeks
Company to hold investment community conference call on October 19
VANCOUVER, Washington, Oct. 13, 2017 (GLOBE NEWSWIRE) — CytoDyn Inc. (OTC.QB:CYDY), a biotechnology company developing new antibody therapies for combating human immunodeficiency virus (HIV) infection, announces that in a meeting held on October 12, 2017, the U.S. Food and Drug Administration (FDA) confirmed the number and type of evaluable patients required for submission of a Biologics License Application (BLA) for PRO 140 as a combination therapy.
The FDA accepted the 40 patients currently enrolled in CytoDyn’s Phase 2b/3 pivotal combination trial as evaluable and further agreed that the trial’s Data Monitoring Committee can conduct an interim efficacy analysis of primary endpoint. The FDA also confirmed that 50 patients will be required for the completion of this trial and agreed to allow more flexibility in the enrollment criteria for the remaining 10 patients. As a result, the Company expects to complete enrollment within the near future. The FDA also confirmed that 300 patients will be required for the safety analysis in a BLA, which can be provided by all of the Company’s HIV trials, providing that those patients have been on a PRO 140 therapy for 24 weeks.
“We are very pleased with the clarity and direction provided by our meeting with the FDA and are now focused on a successful conclusion of our pivotal combination therapy trial in the near future,” said Nader Pourhassan, Ph.D., CytoDyn President and Chief Executive Officer.
CytoDyn’s management will host an investment community conference call on October 19 to discuss the FDA meeting and other business updates. Details of the call will be announced at a later date.
About PRO 140
PRO 140 belongs to a new class of HIV/AIDS therapeutics – viral-entry inhibitors – that are intended to protect healthy cells from viral infection. PRO 140 is a humanized IgG4 monoclonal antibody directed against CCR5, a molecular portal that HIV uses to enter T cells. PRO 140 blocks the predominant HIV (R5) subtype entry into T cells by masking this required co-receptor, CCR5. Importantly, PRO 140 does not appear to interfere with the normal function of CCR5 in mediating immune responses. PRO 140 does not have agonist activity toward CCR5 but does have antagonist activity to CCL5, which is a central mediator in inflammatory diseases. PRO 140 has been the subject of seven clinical trials, each demonstrating efficacy by significantly reducing or controlling HIV viral load in human test subjects. PRO 140 has been designated a “fast track” product by the FDA. The FDA also granted orphan drug designation to PRO 140 for the prevention of graft versus host disease (GvHD). The PRO 140 antibody appears to be a powerful antiviral agent leading to potentially fewer side effects and less frequent dosing requirements compared with daily drug therapies currently in use.
CytoDyn is a biotechnology company focused on the clinical development and potential commercialization of humanized monoclonal antibodies for the treatment and prevention of HIV infection. The Company has one of the leading monoclonal antibodies under development for HIV infection, PRO 140, which has completed Phase 2 clinical trials with demonstrated antiviral activity in humans and is currently in Phase 3 development. PRO 140 blocks the HIV co-receptor CCR5 on T cells, which prevents viral entry. Clinical trial results thus far indicate that PRO 140 does not negatively affect the normal immune functions that are mediated by CCR5. Results from seven Phase 1 and Phase 2 human clinical trials have shown that PRO 140 can significantly reduce viral burden in people infected with HIV. A recent Phase 2b clinical trial demonstrated that PRO 140 can prevent viral escape in patients during several months of interruption from conventional drug therapy. CytoDyn intends to continue to develop PRO 140 as a therapeutic anti-viral agent in persons infected with HIV and to pursue non-HIV indications where CCR5 and its ligand CCL5 may be involved.
