Inovio Pharmaceuticals Adds Dr. Prakash Bhuyan to VGX-3100 Leadership Team for HPV-Related Dysplasia
Dr. Bhuyan’s Accomplishments Include Successful Development of Vaccines at Pfizer and Merck
PLYMOUTH MEETING, Pa., Jan. 04, 2016 (GLOBE NEWSWIRE) -- Inovio Pharmaceuticals, Inc. (NASDAQ:INO) announced today it has appointed Prakash Bhuyan, M.D, Ph.D., as Vice President, Clinical Development. Dr. Bhuyan will lead the clinical development of Inovio’s programs to treat HPV-related pre-cancers (dysplasia). Inovio will take VGX-3100, its treatment for cervical dysplasia caused by the human papillomavirus (HPV), into a phase 3 registration study this year. He will report to Dr. Mark Bagarazzi, Chief Medical Officer.
Prior to joining Inovio, Dr. Bhuyan was Senior Director, Pfizer Vaccine Research, where he led the pivotal clinical study that helped achieve FDA approval in 2014 of the first meningococcal B vaccine to be licensed in the U.S.
Prior to Pfizer, Dr. Bhuyan directed the development and execution of multiple vaccine clinical trials for 4 licensed vaccines at Merck and successfully led an investigational hexavalent pediatric vaccine from phase 2 into phase 3 trials. He earned his M.D. and his Ph.D. in Immunology from the University of Texas Southwestern Medical Center. He completed his fellowship in Infectious Diseases at the University of Pennsylvania, where he currently serves as adjunct assistant professor.
Dr. Mark Bagarazzi, Chief Medical Officer, said, "Dr. Prakash Bhuyan has demonstrated leadership in advancing vaccines to licensure and we are pleased to bring him to Inovio where he will focus on advancing the development of VGX-3100. He will be instrumental in guiding VGX-3100, our immunotherapy for cervical pre-cancer, into phase 3 later this year.”
Inovio’s phase 2b trial showed that histopathological regression of high grade cervical neoplasia (CIN2/3) to low grade neoplasia (CIN1) or no disease occurred in a significantly higher percentage of VGX-3100 recipients compared with placebo recipients. Furthermore, concomitant histopathological regression and clearance of HPV occurred in a significantly higher percentage of VGX-3100 recipients compared with placebo recipients. HPV-specific CD8+ "killer T cells" were also generated in the blood as well as a substantial infiltration of CD8+ cells in the cervical tissue of VGX-3100 recipients, underscoring the role played by Inovio's best-in-class T-cell responses. VGX-3100 was safe and generally well-tolerated.
In VGX-3100-treated women whose high grade dysplasia regressed, most (43 out of 53) completely cleared their lesions to normal (complete response). Moreover, eighty percent of VGX-3100-treated women whose dysplasia regressed also eradicated the infecting HPV genotype (i.e. 16 or 18) from the cervix. This is an important outcome as persistence of the virus is associated with recurrence of the disease.
In 2015, The Lancet reported on results of Inovio’s phase 2b trial in an article entitled, "Safety, efficacy, and immunogenicity of VGX-3100, a therapeutic synthetic DNA vaccine targeting human papillomavirus 16 and 18 E6 and E7 proteins for cervical intraepithelial neoplasia 2/3: a randomized, double-blind, placebo-controlled phase 2b trial," by C. Trimble, et al.
Inovio's VGX-3100 is an immunotherapy containing two DNA plasmids targeting the E6 and E7 oncogenes of HPV types 16 and 18. These oncogenes are responsible for transforming HPV-infected cells into pre-cancerous and cancerous cells. The treatment is administered to patients by injection into muscle (typically in the arm), followed by electroporation using Inovio's CELLECTRA® device. VGX-3100 has been shown to induce a robust immune response against the E6 and E7 oncogenes associated with HPV types 16 and 18.
About HPV and Cervical Dysplasia
Human papillomavirus (HPV) is the most common sexually transmitted disease. At any given time, approximately 11% percent of the world population is infected with HPV. Roughly 75% or less of HPV 16/18 infections are cleared by naturally occurring immune responses in women of all ages.
Persistent HPV infection can lead to dysplasia, or premalignant changes, in cervical cells. HPV types 16 and 18 cause 70% of cervical dysplasia and cervical cancer cases. Each year in the United States, 1.4 million women are diagnosed with CIN1 and 300,000-400,000 women are diagnosed with CIN2/3. All cervical cancers arise from untreated CIN2/3.
