AIM ImmunoTech: Positive Results from Phase 1/2 Ovarian Cancer Study

 Chemokine-modulating IP chemo-immunotherapy combination demonstrated to be well tolerated, and associated with interferon stimulated gene changes that favor cytotoxic T lymphocytes chemoattraction and function

Strength of data support advancement into Phase 2 clinical study

Phase 2 study will be conducted to evaluate immunologic and clinical efficacy of tumor loaded αDC1 vaccine in conjunction with the cisplatin/chemokine modulatory combination regimen

AIM ImmunoTech Inc. (NYSE: American AIM) (“AIM” or the “Company”), an immuno-pharma company focused on the research and development of therapeutics to treat multiple types of cancers, immune disorders, and viral diseases, including COVID-19, the disease caused by the SARS-CoV-2 virus, today announced the publication of positive data from a Phase 1/2 study of intraperitoneal chemo-immunotherapy in advanced recurrent ovarian cancer. The manuscript titled, “Phase I trial combining chemokine-targeting with loco-regional chemo-immunotherapy for recurrent, platinum-sensitive ovarian cancer shows induction of CXCR3 ligands and markers of type 1 immunity1” was published in the American Association for Cancer Research publication, Clinical Cancer Research.

The Phase 1/2 study being conducted by the University of Pittsburgh School of Medicine is designed to evaluate the immunologic and potential clinical effectiveness of intensive locoregional sequential intraperitoneal (IP) cisplatin (IPC) with intravenous (iv) paclitaxel followed by peritoneal infusion of a chemokine modulatory (CKM) regimen composed of a cocktail of IP rintatolimod and interferon-alpha (IFNα) for patients with advanced stage ovarian cancer (III-IV) at primary neoadjuvant setting. AIM ImmunoTech provided rintatolimod (Ampligen®, a dsRNA acting as TLR3 agonist), for the Phase 1/2 study.

“These results represent an important extension of prior studies using human tumor explants that showed Ampligen’s potentially important role as a TLR3 agonist acting synergistically with high-dose IFNα and celecoxib to selectively enhance Teff cell-attractants while suppressing Treg-attractants in the tumor microenvironment with a concomitant increase in the Teff/Treg ratio. This current study shows that similar findings are seen combining Ampligen with chemokine-targeting and chemo-immunotherapy in patients being treated for recurrent ovarian cancer. The importance of boosting the Teff/Treg ratio in the tumor microenvironment is that it is associated with the conversion of ‘cold’ tumors into ‘hot’ tumors, which have an increased sensitivity to chemo-immunotherapy and an improved chance of showing tumor regression. This, of course, creates the potential for a positive survival advantage,” stated David Strayer, MD, Chief Medical Officer, Chief Scientific Officer of the Company and Board Certified in Medical Oncology.
