Xilio Therapeutics (formerly Akrevia Therapeutics), a local bioteh developing tumor-selective immuno-oncology (IO) therapies for patients with cancer, has announced the closing of a $100.5 million Series B financing. Proceeds from the financing will be used to progress Xilio’s first two therapeutic candidates, XTX201 (tumor-selective IL-2) and XTX101 (tumor-selective aCTLA4 mAb) through Investigational New Drug (IND) enabling studies and into Phase 1 clinical trials, as well as advance additional tumor-selective cytokine programs using Xilio’s proprietary technology. Xilio was founded in 2016 and is headquartered in Waltham, Mass.
“We are fortunate to have the support of investors who share our vision to deliver highly potent and effective tumor-selective cancer therapies to patients,” said Rene Russo, Chief Executive Officer of Xilio Therapeutics. “This is a transformational moment for the company as we work to bring our first development programs to patients with cancer and expand our tumor-selective cytokine pipeline.”
Xilio Therapeutics is developing its proprietary technology to create a new class of ultra-potent IO therapies that are activated selectively within the tumor. These tumor-selective therapies are designed to overcome the significant toxicities associated with validated IO therapies, such as IL-2 and aCTLA4, which have historically limited the number of patients that can be treated and prevented patients from completing full courses of treatment. XTX201 (IL-2) and XTX101 (aCTLA4 mAb) have demonstrated tumor-selective activity in preclinical models, significantly widening the potential therapeutic index for these therapies.
The rebranding of the company from Akrevia Therapeutics to Xilio Therapeutics (pronounced “ex-il-ee-oh”) reflects the company’s evolution from a research-focused organization to a development stage company and commitment to developing the next generation of ultra-potent IO therapies. Xilio is derived from the Latin term Ex Nihilo, meaning creation or big-bang, and embodies the company’s vision to create the next generation of transformative cancer treatments for individuals living with cancer by unleashing the full power of highly potent immune therapies precisely in tumors.
