Abstract Text | Background: Addition of a MEK inhibitor to a BRAF inhibitor enhances tumour growth inhibition, delays acquired resistance of the MAPK pathway in BRAF V600-mutated cancers. We assessed the safety and efficacy of tunlametinib (HL-085), a novel highly selective MEK1/2 inhibitor, in combination with vemurafenib in patients(pts) with advanced BRAF-mutated solid tumors. Methods: In this phase I study, pts with advanced solid tumors who had progressed on or shown intolerance to standard treatment were enrolled and received escalating doses of tunlametinib combined with vemurafenib in dose-escalation phase (followed a 3 + 3 design). Patients received tunlametinib at dose levels of 0.5, 6, 9, 12, and 15 mg BID, together with vemurafenib 960 mg BID, in 21-day cycles. In dose-expansion phase, tunlametinib 12mg + vemurafenib 960mg, tunlametinib 12mg + vemurafenib 720mg and tunlametinib 9mg + vemurafenib 720mg dose groups were evaluated. The tunlametinib 9mg + vemurafenib 720mg was determined as the recommended phase 2 dose (RP2D). Results: As of the data cut-off date on 04, Nov, 2022, a total of 72 pts with solid tumors were enrolled. The most common AE were CK elevation, anemia and rash which were predominantly grade 1/2. 33 pts with non-small cell lung cancer (NSCLC) have been evaluated for response. The objective response rate (ORR) was 60.6% (95%CI: 42.1%, 77.1%), a median duration of response (DoR) was 11.3 months (95% CI: 3.9, NE), and a median progression free survival (PFS) was 11.7 months (95% CI: 5.6, NE) . At the RP2D, ORR was 60.0% (95%CI: 32.3%, 83.7%) and mPFS was 10.4 months (95% CI: 5.6, NE). 24 pts with metastatic colorectal cancer (mCRC) at all doses, ORR was 25.0% (95%CI: 9.8%, 46.7%), mDoR was 5.5 months (95% CI: 2.9, NE), and mPFS was 6.2 months (95% CI: 4.8, 7.6). Antitumor activity was also seen in papillary thyroid carcinoma and pancreatic ductal adenocarcinoma. Conclusions: Tunlametinib in combination with vemurafenib showed promising antitumor activity and manageable safety profile in pts with BRAF V600-mutated solid tumors. Further studies are ongoing. Clinical trial identification: NCT03781219. |
