– First-in-class investigational, off-the-shelf immunotherapy utilizing AdenoVerse™ platform designed to activate the immune system to recognize and target HPV-positive solid tumors –
– HPV-associated cancers represent a significant global health burden –
GERMANTOWN, MD, USA I August 17, 2020 IPrecigen, Inc. (Nasdaq: PGEN), a biopharmaceutical company specializing in the development of innovative gene and cellular therapies to improve the lives of patients, today announced that the first patient has been dosed with Precigen’s PRGN-2009, a first-in-class, off-the-shelf (OTS) investigational immunotherapy utilizing the AdenoVerse™ platform designed to activate the immune system to recognize and target HPV+ solid tumors (clinical trial identifier: NCT04432597). HPV-associated cancers represent a significant health burden in indications such as head and neck, cervical, vaginal and anal cancer.
The Phase I portion of the study will use 3+3 dose escalation to evaluate the safety of PRGN-2009 administered as a monotherapy and to determine the recommended Phase II dose (R2PD) followed by an evaluation of the safety of the combination of PRGN-2009 at the R2PD and bintrafusp alfa (M7824), an investigational bifunctional fusion protein, in patients with recurrent or metastatic HPV-associated cancers. The Phase II portion of the study will evaluate PRGN-2009 as a monotherapy or in combination with bintrafusp alfa as a neoadjuvant or induction therapy in patients with newly-diagnosed stage II/III HPV16-positive oropharyngeal cancer.
PRGN-2009 leverages Precigen’s proprietary UltraVector® and AdenoVerse platforms to optimize HPV antigen design. Such design is differentiated from other therapies due to the gorilla adenovector’s large payload capacity and potential for repeat administration due to very low to no seroprevalence in the human population.
PRGN-2009 is under development through a Cooperative Research and Development Agreement, or CRADA, with the laboratory of Dr. Jeffrey Schlom, Chief of the Laboratory of Tumor Immunology and Biology (LTIB), Center for Cancer Research (CCR), National Cancer Institute (NCI). This CRADA has allowed Precigen to rapidly and cost-effectively advance PRGN-2009. The Phase I/II clinical trial of PRGN-2009 is being conducted at the NIH Clinical Center and will be led by Dr. Julius Strauss, Co-Director of the LTIB’s Clinical Trials Group, and Dr. James Gulley, Chief of the Genitourinary Malignancies Branch, CCR, NCI. For patients interested in enrolling in this clinical study, please call NCI’s toll-free number 1-800-4-Cancer (1-800-422-6237) (TTY: 1-800-332-8615), email NCIMO_Referrals@mail.nih.gov, and/or visit the website: https://trials.cancer.gov.
“We appreciate working in collaboration with such renowned partners at the NCI to achieve this important milestone in our efforts to develop a new off-the-shelf immunotherapy treatment option for patients with HPV-associated cancers,” said Helen Sabzevari, PhD, President and CEO of Precigen. “We are excited to investigate Precigen’s proprietary gorilla adenovector platform for the first time in a clinical setting and achieve this milestone during the COVID-19 global pandemic.”
About HPV-associated Cancers
HPV infects the squamous cells that line the inner surfaces of certain organs and, consequently, most HPV-related cancers are a type of cancer called squamous cell carcinoma. Some cervical cancers come from HPV infection of gland cells in the cervix and are referred to as adenocarcinomas.1 HPV-related cancers include cervical, oropharyngeal, anal, penile, vaginal, and vulvar.1 Nearly 44,000 HPV-associated cancers occur in the United States each year. Of these, approximately 25,000 occur in women and 19,000 occur in men.2 HPV is considered responsible for more than 90% of anal and cervical cancers, about 70% of vaginal and vulvar cancers, and more than 60% of penile cancers.2 Recent studies indicate that about 70% of cancers of the oropharynx also may be related to HPV.2
