Clinical Abstract from CytoDyn’s PRO 140 Phase 2b HIV Monotherapy Trial Now Available on ASM Microbe 2016 Conference Website

VANCOUVER, Washington, May 16, 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 that an abstract featuring clinical data from the Company’s PRO 140 monotherapy Phase 2b extension study in patients with HIV is now available online on the ASM Microbe 2016 website at: http://www.abstractsonline.com/pp8/#!/4060/presentation/16215.

Findings from the study will be discussed in an oral presentation entitled “PRO 140 SC Monotherapy Provides Long-term, Full Virologic Suppression in HIV Patients” by Paul J. Maddon, MD, PhD, at the ASM Microbe 2016 Conference on Monday, June 20, 2016, at 9:00 a.m. Eastern Time. The conference is being held at the Boston Convention and Exhibition Center.

“We are honored that not only ASM Microbe Conference has accepted our abstract and granted us an oral presentation spot, but has also selected our abstract for an ASM-sponsored press release to highlight our research to the journalists covering this Conference,” said Nader Pourhassan, PhD, the president and CEO of CytoDyn. “We believe that PRO 140 has great potential as an alternative or addition to current standard of care and is currently conducting two phase 3 trials for both of these populations.”

PRO 140 is a humanized monoclonal antibody that is being studied in HIV-infected patients as a standalone treatment and in combination with 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 ASM Microbe 2016 Conference
ASM Microbe 2016 is the merger of the American Society for Microbiology’s two premier events, the ASM General Meeting and ICAAC (Interscience Conference on Antimicrobial Agents and Chemotherapy). This year’s event is expected to attract more than 10,000 attendees to gain valuable insights from the field's foremost leaders, interact with multi-disciplinary microbiologists, and meet leading product and service providers.

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 fully 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 finished 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 six 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.
