CytoDyn Release: Evidence Of HIV Suppression With PRO 140 Monotherapy Reaching Nearly 11 Months
CytoDyn to Request Meeting With FDA to Discuss Registration Pathway for PRO 140 Monotherapy Indication
Dr. Paul J. Maddon, an Inventor of PRO 140, Named Senior Science Advisor
VANCOUVER, Wash., July 15, 2015 (GLOBE NEWSWIRE) -- CytoDyn Inc. (OTCQB:CYDY), a biotechnology company focused on the development of new therapies for combating human immunodeficiency virus (HIV) infection, today announced that its ongoing extension study of PRO 140 monotherapy in HIV-infected patients has shown complete viral-load suppression for nearly 11 months. The Company believes that complete virologic suppression through treatment with a single agent, rather than through the widely used HAART combination therapy, could present a significant opportunity to treat HIV infection.
Management will hold an investment community conference call on Friday, July 17, 2015, at 10:00 a.m. PT to discuss the Company's future plans for PRO 140 (see details for the call below).
In addition, Paul J. Maddon, M.D., Ph.D., a biotechnology entrepreneur and an inventor of PRO 140, has been named Senior Science Advisor to CytoDyn. In this capacity, Dr. Maddon will advise CytoDyn on the development program for PRO 140. Dr. Maddon is the founder and Vice Chairman of Progenics Pharmaceuticals, Inc. and also serves as a director and consultant to several biotechnology and specialty pharmaceutical companies. He previously served as Chairman, Chief Executive Officer, and Chief Science Officer of Progenics.
Dr. Maddon is a molecular virologist and immunologist who has made major contributions to our understanding of HIV entry and infection. As a graduate student at Columbia University, he isolated the gene encoding CD4 and demonstrated that CD4 serves as the primary receptor for entry of HIV into immune system cells. While at Progenics, Dr. Maddon and his collaborators discovered that a second receptor, CCR5, is also required for HIV entry. He led the discovery and development of PRO 140, a humanized monoclonal antibody to CCR5 designed to treat HIV infection.
Dr. Maddon has served on the editorial board of Journal of Virology and chaired and served on numerous scientific advisory committees of the National Institutes of Health and Department of Defense. He has also received several honors and has been awarded many federal research grants and contracts. At Columbia University, he received a B.A. from the College, an M.D. from the College of Physicians and Surgeons, and a Ph.D. in biochemistry and molecular biophysics from the Graduate School of Arts and Sciences.
Dr. Nader Pourhassan, President and CEO, commented: "We are delighted that Dr. Paul Maddon, an inventor of PRO 140 and distinguished scientist, will play a more active role in guiding CytoDyn through our current Phase 3 program in combination therapy, as well as our monotherapy discussions with the FDA. We are confident that Dr. Maddon can add significant value to the PRO 140 program, helping us to optimize and accelerate its commercial development."
"I am very excited to contribute to the PRO 140 development effort at CytoDyn" said Dr. Maddon. "PRO 140 is a potent and well-tolerated antiviral agent that may play an important role in the treatment of HIV infection."

CytoDyn is a biotechnology company focused on the clinical development and potential commercialization of humanized monoclonal antibodies for the treatment and prevention of Human Immunodeficiency Virus (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. For more information on the Company, please visit www.cytodyn.com.
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.
