FRUSICA-1 study of fruquintinib + sintilimab showed meaningful results in endometrial cancer, with 37% ORR in serous carcinoma patients. 5. Phase IV study of fruquintinib in 2,798 colorectal cancer patients demonstrated manageable safety profiles in both monotherapy and combination therapy groups.

Insights

Oncology Clinical Researcher

Multiple positive clinical trial results from HUTCHMED's oncology pipeline to be presented at ASCO, including savolitinib's successful Phase III data.

The upcoming ASCO presentations reveal significant progress across HUTCHMED's oncology pipeline, with several compounds showing promising efficacy. The SACHI Phase III study results are particularly notable, as savolitinib plus osimertinib met its primary progression-free survival endpoint in EGFR-mutant, MET-amplified NSCLC patients who progressed on prior EGFR inhibitor therapy. This data has already supported a New Drug Application in China that received priority review status, potentially accelerating market access.

The SAVANNAH Phase II data further strengthens savolitinib's profile by demonstrating the combination's efficacy versus savolitinib plus placebo, with important CNS activity showing reduced central nervous system progression and fewer new CNS lesions - a critical clinical benefit for lung cancer patients.

For ranosidenib (HMPL-306), the Phase I results demonstrate a favorable safety profile with target inhibition and promising efficacy signals, particularly in lower-grade glioma patients where a 100% disease control rate was achieved, indicating potential for treating IDH1/2 mutant tumors.

The FRUSICA-1 study data for fruquintinib plus sintilimab in endometrial cancer showed meaningful clinical activity, with notable efficacy in difficult-to-treat serous carcinoma patients (ORR 37.0%, DCR 88.9%). Importantly, responses were consistent regardless of prior neoadjuvant/adjuvant chemotherapy exposure.

The extensive Phase IV fruquintinib data across 2,798 colorectal cancer patients demonstrates a manageable safety profile both as monotherapy and in combination regimens, with longer treatment duration in the combination therapy group suggesting improved outcomes. The consistent safety profile across age groups, including elderly patients, supports broad clinical utility.

HONG KONG and SHANGHAI and FLORHAM PARK, N.J., May 23, 2025 (GLOBE NEWSWIRE) -- HUTCHMED (China) Limited (“HUTCHMED”) (Nasdaq/AIM:​HCM; HKEX:​13) today announces that new data from several studies of compounds discovered by HUTCHMED including savolitinib, ranosidenib, fruquintinib and surufatinib, will be presented at the American Society of Clinical Oncology (“ASCO”) Annual Meeting taking place on May 30 – June 3, 2025 in Chicago, USA.

Results from the SACHI China Phase III study of savolitinib in combination with osimertinib in patients with locally advanced or metastatic epidermal growth factor receptor (“EGFR”) mutation-positive non-small cell lung cancer (“NSCLC”) with MET amplification after disease progression on EGFR inhibitor therapy will be presented at a late breaking oral presentation. SACHI had met the pre-defined primary endpoint of progression-free survival (PFS) in a planned interim analysis. SACHI data supports the New Drug Application (NDA) for this oral-only treatment, which has been accepted and granted priority review in China.

Further data with additional analysis stratified by brain metastasis status from a high MET overexpression and/or amplification treatment subset of the SAVANNAH Phase II study of the savolitinib and osimertinib combination in NSCLC patients harboring EGFR mutation and MET amplification or overexpression after progressing on osimertinib were reported. The savolitinib and osimertinib combination demonstrated better efficacy outcomes compared to savolitinib plus placebo. The combination showed promising central nervous system (“CNS”) activity, with reduced CNS progression and fewer new CNS lesions.

Results will be presented from the dose-escalation stage of the Phase I study of ranosidenib (HMPL-306), a novel, small-molecule, highly selective oral dual-inhibitor of both Isocitrate dehydrogenase (“IDH”) 1 and IDH2 enzymes, being studied in patients with locally advanced or metastatic solid tumors with IDH mutations. Results show that the compound was well tolerated, showing target inhibition and durable responses in patients. Efficacy signals were observed especially in the efficacy evaluated group of lower-grade glioma patients (N=14), with an objective response rate (“ORR”) of 7.1% and a disease control rate (“DCR”) of 100%.

Results will also be presented from the sub-group analyses of the FRUSICA-1 open-label, single-arm, pivotal Phase II study to evaluate the efficacy and safety of fruquintinib plus sintilimab in previously treated advanced endometrial cancer (EMC) patients with pMMR (proficient mismatch repair) status. Efficacy findings for patients with serous carcinoma (N=27) were clinically meaningful and characterized by responses similar to those observed in full trial population (N=98), with an Independent Review Committee (“IRC”)-assessed ORR of 37.0% and a DCR of 88.9%. The analysis of whether the response was affected by prior neoadjuvant/adjuvant chemotherapy (“NACT/ACT”) showed durable and clinically meaningful responses regardless of whether the patient had received NACT/ACT. Results were comparable for patients with and without prior NACT/ACT, with an IRC-assessed ORR of 34.0% versus 31.4% and DCR of 85.1% versus 82.4%, respectively.

Results from two subgroup analyses of a Phase IV study of fruquintinib involving 2,798 colorectal cancer patients in China will be presented. In the subgroup analysis evaluating the safety of fruquintinib as monotherapy and in combination therapy, fruquintinib demonstrated a manageable safety profile in both groups. Treatment-emergent adverse events (TEAE) of Grade 3 or above occurred in 23.94% in the fruquintinib monotherapy group and 26.06% in the combination therapy group with other anti-cancer treatments. The most common treatment related adverse events (TRAE) of any grade in both groups were palmar-plantar erythrodysesthesia (PPES) and hypertension. The combination therapy group exhibited a longer treatment duration, potentially indicating improved patient outcomes. In the subgroup analysis by age, the safety of fruquintinib was assessed in younger (age <50) and late-elderly (age ≥75) patients. The safety profile was comparable across both age groups, with younger patients receiving more intensive treatment. Combination therapy with fruquintinib also showed a longer duration than monotherapy in both age subgroups, which may suggest improved survival potential.
