Completed Phase I DIONE-01 study demonstrates clinical activity and long-term safety of roginolisib, a unique allosteric modulator of PI3Kδ Patients with uveal melanoma showed a doubling of overall survival compared to historical controls Site activation ongoing for randomized Phase II OCULE-01 study in uveal melanoma GENEVA and AMSTERDAM, Dec. 11, 2024 /PRNewswire/ -- iOnctura, a clinical-stage biopharmaceutical company combating neglected and hard-to-treat cancers, today provides a clinical update on its lead asset, roginolisib. Results from the completed Phase I DIONE-01 study are due to be presented at the European Society for Medical Oncology Immuno-Oncology (ESMO-IO) annual congress tomorrow, 12 December at 12:30 CET (presentation 164P). Allosteric modulator of PI3Kδ, roginolisib, has a unique chemical structure and binding mechanism which makes it highly specific for PI3Kδ, giving it an advantageous pharmacology profile and an unprecedented safety profile compared to previous generations of PI3Kδ inhibitors. Roginolisib is being investigated in solid and hematological malignancies including uveal melanoma (UM), a rare cancer of the eye. Eye melanoma is a rapidly growing market which is projected to be worth USD 9.56B by 2032[1]. The two-part Phase I study DIONE-01, firstly evaluated continuous daily dosing of roginolisib [at 10, 20, 40 and 80 mg] in 24 patients with pretreated solid tumors and follicular lymphoma (FL), and secondly evaluated a dose confirmation cohort in 20 UM patients. Results from DIONE-01 show: Study met its primary objective to determine the safety of the anticipated optimal biologically effective dose (BED): Roginolisib was well tolerated at the recommended Phase II dose (RP2D) of 80mg, with <7% Grade 3/4 treatment-emergent adverse events (TEAEs) considered to be related to roginolisib. TEAEs did not result in immune-related toxicity, or dose-limiting toxicity, in either solid tumor or hematological patients. In contrast to prior PI3Kδ inhibitors, roginolisib dosing did not require dose modifications. Roginolisib is well tolerated over long periods of treatment, up to 4.5 years. Median overall survival (OS) was 16 months for the 29 patients with UM treated with roginolisib, who had previously received a median of two prior therapies. This exceeds the median OS of 7 months observed in historical controls in patients receiving immunotherapies as second line treatment[2]. Median progression free survival (PFS) was 5 months for patients treated with roginolisib versus less than 3 months for historical controls2. Clinical findings validate the mechanism of action of roginolisib: roginolisib reduces immune-suppressive immune cells and chemokines, UM-related tumor clones (ctDNA) and PI3K-related signaling indicating a rebalancing of the immune system. Catherine Pickering, Chief Executive Officer of iOnctura, said: "The Phase I DIONE-01 data highlight the benefits of roginolisib for patients with uveal melanoma and advanced cancers. Roginolisib's unique allosteric binding mechanism has translated into a differentiated beneficial clinical profile, including a doubling of overall survival compared to historical controls in uveal melanoma. We are delighted to announce these data support progression of roginolisib into a randomized Phase II study." Professor Michele Maio, University of Siena and Principal Investigator of the roginolisib studies, added: "Being able to continue to investigate roginolisib in a randomized Phase II study is a positive step to understand more about this already well tolerated molecule. Roginolisib has given prolonged disease stabilization to patients with uveal melanoma who have exhausted all other therapeutic options. So far, these patients have maintained a good quality of life without major limitations. I'm looking forward to seeing what the Phase II trial delivers over the coming months." Activation of trial sites for the Phase II OCULE-01 study (NCT06717126) investigating roginolisib versus investigator's choice in the second-line+ treatment of uveal melanoma is ongoing.

Phase II study in non-small-cell-lung-cancer (NSCLC) to be run in collaboration with the ETOP IBCSG Partners Foundation across sites in Europe Study will investigate dostarlimab + roginolisib +/- docetaxel in patients with NSCLC resistant to first-line checkpoint inhibitor therapy GENEVA and AMSTERDAM, July 9, 2024 /PRNewswire/ -- iOnctura, a clinical-stage biopharmaceutical company combating neglected and hard-to-treat cancers, today announces expansion of the clinical trial program for lead pipeline asset, roginolisib. Via clinical collaboration agreements with the ETOP IBCSG Partners Foundation and GSK, roginolisib will be evaluated in combination with dostarlimab in NSCLC. 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. Dostarlimab is a PD-1-blocking antibody approved for certain patients with endometrial cancer, which has also demonstrated clinical activity in combination with chemotherapy in NSCLC4. Under the terms of the agreement with iOnctura, GSK will supply dostarlimab for use in a randomized Phase II clinical trial in NSCLC patients resistant to first-line checkpoint inhibitor therapy, with or without docetaxel. iOnctura will retain worldwide rights to roginolisib. The ETOP IBCSG Partners Foundation is a leading organization performing international clinical and translational research in thoracic malignancies and breast cancer. Through the clinical collaboration, iOnctura will be provided access to a network of highly experienced investigators for the Phase II study. Professor Solange Peters, MD, PhD, Chair of Medical Oncology and the Thoracic Malignancies Programme in the Department of Oncology at the University Hospital of Lausanne will be the primary coordinating investigator of the study. 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." Solange Peters, Professor and Chair of Medical Oncology & Thoracic Malignancies Programme in the Department of Oncology at the University Hospital of Lausanne in Lausanne, Switzerland, commented: "On behalf of the ETOP IBCSG Partners Foundation, we are intrigued by the benefit/risk profile of roginolisib. In patients who no longer respond to current therapies, we wish to investigate whether roginolisib in combination with dostarlimab provides a novel treatment option. ETOP IBCSG Partners Foundation is committed to investigate novel treatment options to help our patients."

The expansion to roginolisib’s clinical programme is via collaborations with ETOP IBCSG Partners Foundation and GSK. Image credit: Shutterstock/tomertu. Fresh from raising nearly $86m in financing last month, iOnctura will now start evaluating lead asset roginolisib in non-small cell lung cancer (NSCLC). The expansion to roginolisib’s clinical programme is via clinical collaboration agreements with the ETOP IBCSG Partners Foundation and GSK , iOnctura said in a 9 July press release. The Swiss biopharma iOnctura outlined plans for a Phase II study that will investigate roginolisib in combination with GSK’s PD-1 inhibitor Jemperli (dostarlimab). The combo therapy will be evaluated in NSCLC patients resistant to first-line checkpoint inhibitor therapy, with or without docetaxel. Roginolisib is an allosteric modulator of phosphoinositide 3-kinase-δ (PI3Kδ), which iOnctura says is “widely recognised as a ‘master switch’ of cancer.” Inhibition of the protein elicits an anti-tumour effect, which induces immune system activity against cancer cells.  In January this year, roginolisib received an orphan drug designation from the US Food and Drug Administration (FDA). iOnctura is basing the combination with GSK’s programmed death receptor (PD-1) on “emerging clinical and translational biomarker data,” adding that it may prevent or reverse drug resistance in NSCLC. This enhanced anti-tumour immune activity would also be without significant addition of toxicity, according to the biopharma.

The biopharma reported positive efficacy results at the 80mg dose, with grade 1 and 2 adverse events observed in the continuous daily dosing portion of the trial for patients with solid tumors. iOnctura’s CEO Catherine Pickering said: “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.” P13K inhibitors faced a setback in recent years after the FDA’s Oncologic Drugs Advisory Committee (ODAC ) lost confidence in the safety profile of the drugs. The agency recommended that future approvals of PI3K inhibitors for haematologic malignancy indications should require randomised trial data, as per a vote in 2022. The decision was based on high levels of fatal adverse events (AEs) and toxicity observed in patients taking the drug class. Roche made a recent advancement in the space, securing FDA priority review in breast cancer for the PI3K inhibitor inavolisib as a combination therapy with fulvestrant and Pfizer ’s Ibrance (palbociclib). iOnctura raised €80m ($85.8m) in Series B financing earlier this year, helping to fund Phase II activity for roginolisib and its other candidate cambritaxestat, autotaxin inhibitor.
