Roginolisib is an allosteric modulator of PI3Kδ, widely recognized as a 'master switch' of cancer. Inhibition of PI3Kδ unleashes a multi-pronged anti-tumor and immune response to combat the tumor1 . Roginolisib has demonstrated an unprecedented clinical profile in solid and liquid cancers2, with 44 patients treated to date. Emerging clinical and translational biomarker data supports the hypothesis that combining roginolisib with a programmed death receptor-1 (PD-1) targeting agent, with or without docetaxel, may prevent or reverse drug resistance in NSCLC and may show synergistic anti-tumor immune activity without significant addition of toxicity3. Catherine Pickering, Chief Executive Officer of iOnctura, said: "As iOnctura moves into the next phase of clinical development, we are thrilled to be able to assess the effectiveness of roginolisib in combination with dostarlimab for the treatment of NSCLC. The successful uveal melanoma data reported so far, combined with a rich preclinical data package, support the rationale to expand our development program with potentially synergistic combinations in NSCLC." iOnctura is a clinical-stage biopharmaceutical company combating neglected and hard-to-treat cancers with precision oral small molecules that target cancers in novel ways. The bold new treatments extend lives and improve healthspans, changing the outlook for patients and their families. Two therapeutic candidates have progressed into mid-stage clinical development: roginolisib is the first allosteric modulator of PI3Kδ and cambritaxestat is the only autotaxin inhibitorautotaxin inhibitor in clinical development to treat cancer. iOnctura BV is headquartered in Amsterdam, The Netherlands with its wholly owned Swiss subsidiary, iOnctura SA, located in Geneva, Switzerland. iOnctura is backed by specialist institutional investors including Syncona, EIC Fund, M Ventures, Inkef Capital, VI Partners and Schroders Capital. 1 AACR Volume 3, Issue 4, April 2023, Poster presentation, SITC 2022
