HOUSTON, May 18, 2022 (GLOBE NEWSWIRE) — 7 Hills Pharma LLC (“7 Hills” or “7HP”), together with The University of Texas MD Anderson Cancer Center (“MD Anderson”) and Texas Heart Institute (“THI”), released a new study in The Journal of Clinical Investigation, describing the use of 7HP’s novel integrin activator 7HP349 to convert “cold” or non-immunogenic tumor microenvironments to a “hot,” T cell-enriched state, improving the effectiveness of immune checkpoint blockade. The article, entitled “LFA-1 activation enriches tumor-specific CD8+ T cells in a cold tumor model and synergizes with CTLA-4 blockade,” was published by a team at MD Anderson led by Yared Hailemichael, Ph.D., assistant professor of Melanoma Medical Oncology, with co-authors from 7 Hills and THI.
7HP349 is a member of a family of small molecule integrin activators discovered at the Texas Heart Institute in the laboratories of Dr. Peter Vanderslice, Dr. Ronald J. Biediger, and Dr. Darren G. Woodside. The family of compounds was generated using a rational design approach based on their deep understanding of and relationship between the biology and three-dimensional structure of integrins.
“This landmark publication is the result of years of forward-looking thinking, innovative chemistry, and keen scientific investigation amongst our multidisciplinary teams and with our interinstitutional partners across the Texas Medical Center,” said Dr. Vanderslice. “Our goal is to bring more effective, less toxic immunotherapy treatments to cancer patients, and we are proud to see our unique approach to immune augmentation validated with this publication.”
7HP partnered with THI in 2014 to commercially develop the technology and soon teamed up with Hailemichael to elucidate the biology underlying these first-in-concept integrin activators.
“Our findings shed light on a new approach to improving cancer immunotherapy,” Hailemichael said. “We are excited to help move this therapeutic a step closer to additional clinical studies.”
7HP has garnered both FDA Fast Track and Orphan Drug designations for 7HP349 in advanced melanoma, highlighting the significant unmet needs of these patients. 7HP also recently completed a Phase I clinical trial on 7HP349 demonstrating oral bioavailability and a clean safety profile. “We are grateful for the support of the National Cancer Institute’s SBIR program that has funded this work from pre-clinical validation and IND-enabling studies through completion of Phase I clinical testing,” said Upendra Marathi, CEO of 7HP. “Without their support, both financial and non-financial, our novel approach to reversing resistance to immune checkpoint inhibition could not have been possible.”

About 7HP349
7HP349 is 7HP’s lead, clinical-stage integrin agonist. It is a first-in-class, orally delivered small molecule that safely and selectively activates the integrins LFA-1 and VLA-4 to augment the antigen-specific immune response. In preclinical models, 7HP349 has been shown improve the effectiveness of a broad range of immune checkpoint inhibitors and a wide variety of infectious disease vaccines. In a Phase I clinical trial, 7HP349 demonstrated oral bioavailability and clean safety profile at exposures well exceeding therapeutic levels.
