ASM Microbe 2016 Presentation of Clinical Results From CytoDyn’s Phase 2b Monotherapy Extension Study Now Available

VANCOUVER, Washington, June 22, 2016 (GLOBE NEWSWIRE) -- CytoDyn Inc. (OTC.QB:CYDY), a biotechnology company focused on the development of new monoclonal antibody therapies for combating human immunodeficiency virus (HIV) infection, announces the availability of Paul J. Maddon, M.D., Ph.D.’s June 20 presentation at the ASM Microbe 2016 Conference discussing clinical results from the Company’s Phase 2b monotherapy extension study in patients with HIV on CytoDyn’s website.  Dr. Maddon’s presentation can also be accessed by inserting the following link into your browser:

“The Phase 2b extension study showed that PRO 140 delivered in weekly subcutaneous injections provided full virologic suppression and was well tolerated in a group of HIV treatment-experienced patients for more than one year,” said Dr. Maddon, inventor of PRO 140 and senior science advisor to CytoDyn.  “It was exciting to discuss these outstanding clinical results in an oral presentation to conference attendees and at a special press conference for journalists.”

Nader Pourhassan, Ph.D., president and CEO of CytoDyn, commented: “The current standard of care for HIV patients, which is highly active antiretroviral therapy (HAART), has many shortcomings that include required daily dosing of multiple pills and toxicity that can lead to compliance issues.  In essence, the clinical results from our monotherapy extension study indicate that PRO 140 may offer a simple, long-acting, single-agent maintenance therapy in select patients after initial treatment with HAART.  We are currently evaluating PRO 140 in two Phase 3 clinical trials as both an alternative and addition to HAART.”

PRO 140 is a humanized monoclonal antibody that is being studied in HIV-infected patients as a standalone treatment and in combination with standard of care HAART therapy. It has shown to have potent antiviral activity in seven clinical trials with HIV patients infected with the R5 strain of HIV, which accounts for approximately 70% of infected Americans and up to 90% of those newly diagnosed. This Phase 2b study evaluated PRO 140 as a monotherapy in treatment-experienced patients with the R5 subtype of HIV was completed in January 2015, and an extension of the study in certain responder patients is ongoing. In April 2016, CytoDyn announced that 10 HIV-infected patients in this ongoing extension study have achieved complete viral load suppression for at least 18 months, with several patients approaching 20 months. To date, PRO 140 has been evaluated in more than 200 subjects in various studies.

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 candidate by the FDA. The PRO 140 antibody appears to be a powerful antiviral agent leading to potentially fewer side effects and less frequent dosing requirements as compared to daily drug therapies currently in use.

About CytoDyn
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 man and is currently in Phase 3. 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 weeks 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.
