Insights

Biotech Investment Analyst

OnKure's Q4/FY2024 results reveal a strong financial position with $110.8 million cash, providing runway through Q4 2026. This extended cash position significantly derisks the company's near-term financial outlook, allowing them to advance their PI3Kα inhibitor pipeline through multiple clinical readouts without immediate financing pressure.

The preliminary data from their lead candidate OKI-219 demonstrates an encouraging safety profile in the PIKture-01 trial, with notably no hyperglycemia, stomatitis, or rash - side effects that have historically the utility of other PI3Kα inhibitors. This safety differentiation, if maintained in larger trials with demonstrated efficacy, could represent a meaningful competitive advantage in the PI3Kα inhibitor landscape.

R&D expenses increased to $14.4 million in Q4 (63.6% YoY increase), reflecting appropriate investment in their expanding clinical programs. The planned expansion of their PI3Kα franchise to include a pan-mutant selective program adds pipeline depth and could address additional patient populations with PI3Kα mutations beyond H1047R.

Multiple upcoming catalysts provide near-term value inflection opportunities: additional PIKture-01 data in H2 2025, announcement of their pan-mutant inhibitor candidate in Q2 2025, and planned initiation of additional clinical trials. The recently completed merger and $65 million financing provide organizational stability to execute on these objectives.

Oncology Drug Development Expert

OnKure's approach to PI3Kα inhibition shows promising differentiation in the preliminary safety data from PIKture-01. PI3Kα is a critical node in cancer signaling, particularly in HR+/HER2- breast cancer with PI3Kα mutations, which represent approximately 40% of patients.

The absence of hyperglycemia, stomatitis, and rash in the preliminary OKI-219 data is noteworthy. Current approved PI3Kα inhibitors like alpelisib are effective but have significant tolerability challenges, with hyperglycemia occurring in 63.7% of patients in the SOLAR-1 trial. If OKI-219 maintains this favorable safety profile while demonstrating efficacy, it could address a significant unmet need for more tolerable treatment options.

The company's enrollment progress through dose escalation (completed through 1200mg BID in monotherapy and nearing completion of 900mg BID in combination with fulvestrant) without dose-limiting toxicities is encouraging. This suggests they may achieve therapeutic levels without encountering significant toxicity barriers.

The expansion into a pan-mutant PI3Kα program is strategically sound, as it would address the three most common PI3Kα mutations (H1047X, E542K, and E545K) while maintaining selectivity over wild-type PI3Kα. This could potentially broaden the addressable patient population beyond their current focus on H1047R mutations, while maintaining a favorable therapeutic window.

— PIKture-01 trial update including additional PK data, mature single agent and initial combination data expected in the second half of 2025; reported encouraging preliminary data in December 2024

— Expansion of PI3Ka franchise to include a pan-mutant selective program; development candidate expected to be announced in Q2 2025

— $111M in cash and cash equivalents expected to be sufficient to fund operations through multiple PIKture-01 clinical readouts and anticipated milestones into Q4 2026

BOULDER, Colo., March 10, 2025 (GLOBE NEWSWIRE) -- OnKure Therapeutics, Inc. (Nasdaq: OKUR), a clinical-stage biopharmaceutical company focused on developing novel precision medicines in oncology, today reported financial results for the fourth quarter and full year ended December 31, 2024, and provided recent business highlights.

“I am extremely pleased with the progress we made last year. With three PI3Ka inhibitor programs, including one in clinical development and a second development candidate expected next quarter, we are committed to developing product candidates that address the needs of patients who suffer from diseases implicated by PI3Ka, which is a key mediator in cancer growth signaling,” said Nicholas Saccomano, Ph.D., President and Chief Executive Officer of OnKure.

“The extensive expertise of our research and development team in discovering development candidates with favorable drug properties is our strength, and the entire OnKure team is contributing to the execution of our strategy. This year, we expect to report additional OKI-219 data from PIKture-01, announce our pan-mutant inhibitor program, and declare plans to initiate additional clinical trials,” concluded Dr. Saccomano.

Recent Business Highlights and Upcoming Anticipated Milestones

• PIKture-01 trial Part A Monotherapy – In December 2024, OnKure announced encouraging preliminary safety, tolerability, and pharmacokinetic (“PK”) data from the part A single-agent arm of PIKture-01 with a data cut-off of October 28, 2024. These preliminary data showed OKI-219 was well tolerated across all dose levels, with no hyperglycemia, stomatitis, or rash observed. Additionally, only grade 1 treatment-related adverse events (“TRAEs”) were reported with no dose interruptions, delays, reductions, or discontinuations reported for any adverse events. To date, OnKure has completed the enrollment of patients in the Part A monotherapy arm of PIKture-01 through the 1200 mg BID cohort level with no dose limiting toxicities observed in the completed cohorts. OnKure is currently enrolling the last cohort with a top dose of 1500 mg BID and enrollment in Part A is almost complete. OnKure expects to provide a clinical update in the second half of 2025.

• PIKture-01 Part B Fulvestrant Combination – In the fourth quarter of 2024, OnKure initiated patient dosing in Part B of the PIKture-01 trial, evaluating OKI-219 in combination with fulvestrant in patients with PI3Kα^H1047R mutated HR+/HER2- metastatic breast cancer. To date, OnKure has enrolled patients in the Part B fulvestrant combination arm of PIKTure-01 through the 900 mg BID cohort with no dose limiting toxicities observed for all completed cohorts through 600 mg BID and enrollment in the dose escalation portion of Part B is almost complete. OnKure expects to report initial combination data with fulvestrant in the second half of 2025.

• Pan-mutant Program – OnKure believes a PI3Kα “pan-mutant” inhibitor will need to demonstrate approximately 10-fold selectivity against each of the most common mutations (PI3Kα^H1047X, PI3Kα^E542K, and PI3Kα^E545K) over wild type. OnKure expects to announce its pan-mutant development candidate in the second quarter of 2025.

• Merger and Financing – As previously announced, the merger between OnKure, Inc. and Reneo Pharmaceuticals, Inc. closed on October 4, 2024. Concurrent with the closing of the merger, the company closed a $65 million financing, changed its name to OnKure Therapeutics, Inc. and began trading on the Nasdaq Global Market on October 7, 2024 under the new ticker symbol “OKUR”.
  

Fourth Quarter 2024 Financial Results

Cash and cash equivalents were approximately $110.8 million as of December 31, 2024.

Research and development (R&D) expenses were $14.4 million for the fourth quarter of 2024, compared to $8.8 million for the fourth quarter of 2023. The increase of $5.6 million was primarily driven by an increase of $3.4 million in clinical trial and manufacturing related expenses in addition to $2.1 million of higher personnel-related costs, including share-based compensation charges.

General and Administrative (G&A) expenses were $4.3 million for the fourth quarter of 2024, compared to $1.1 million for the fourth quarter of 2023. The increase of $3.2 million was primarily driven by an increase in personnel-related costs of $2.0 million and an increase in consulting and professional service expenses of $1.2 million including, audit, tax, insurance, board of director compensation and other consulting expenses.

Net loss and net loss per share for the fourth quarter of 2024 were $17.4 million or $1.37 per share, compared to $9.5 million, or $30.14 per share, for the fourth quarter of 2023.
