HUTCHMED Highlights Clinical Data to be Presented at 2023 ESMO Asia and ESMO Immuno-Oncology Congresses

Hong Kong, Shanghai & Florham Park, NJ - Friday, December 1, 2023: HUTCHMED (China) Limited ("HUTCHMED") (Nasdaq/AIM: HCM; HKEX: 13) today highlights that new clinical data from several ongoing studies with HUTCHMED investigational drug candidates fruquintinib, surufatinib and HMPL-295, which will be presented at the upcoming European Society for Medical Oncology ("ESMO") Asia Congress, taking place on December 1-3, 2023 in Singapore, and the ESMO Immuno-Oncology Congress, taking place on December 6--8, 2023 in Geneva, Switzerland.

HMPL-295:

 
Title:               A first in human, open-label, dose-escalation study 
                      of ERK1/2 inhibitor HMPL-295 in patients with advanced 
                      solid tumors 
Lead Author:         Rujiao Liu, Department of Medical Oncology, Fudan 
                      University Shanghai Cancer Center, Shanghai, China 
Type:                Oral presentation 
Abstract # &         77MO 
 Link: 
Session & Location:  ESMO Asia - Developmental and precision medicine (ID 
                      29), Hall 402 
Date & Time:         Friday, December 1, 2023, 11:50 am Singapore time 
 

This presentation will report data from a multi-center, open-label clinical trial to evaluate safety, tolerability, pharmacokinetics and preliminary efficacy profile of HMPL-295, and to determine the maximum tolerated dose ("MTD") and recommended Phase II dose in patients with advanced malignant solid tumors. The continuous-administration MTD was determined to be 50 mg QD, and intermittent administration studies are ongoing.

HMPL-295 is an investigational, selective, oral inhibitor of extracellular signal-regulated kinase 1 & 2 (ERK1/2), which is a downstream component of the RAS-MAPK pathway signaling cascade. The investigational compound has the potential to address intrinsic or acquired resistance from upstream mechanisms such as RAS, RAF and MEK. HMPL-295 is one of several investigational compounds discovered by HUTCHMED that target the RAS-MAPK pathway.

These presentations will report results from the cervical cancer and NSCLC patient cohorts of the basket clinical trial in China of fruquintinib plus sintilimab. This trial is an open-label, multi-center, non-randomized, Phase study to assess the safety and efficacy of fruquintinib in combination with sintilimab in patients with advanced cervical cancer, endometrial cancer ("EMC"), gastric cancer (GC), hepatocellular carcinoma (HCC), NSCLC or renal cell carcinoma ("RCC"). Data from the EMC and RCC cohorts of this trial led to the initiation of registration enabling programs. This combination treatment showed promising antitumor activity in advanced cervical cancer and NSCLC patients, particularly for patients with PD-L1 positive status. This combination treatment also showed manageable toxicity profiles consistent with that seen in other cohorts.

Fruquintinib is a selective oral inhibitor of vascular endothelial growth factor receptors ("VEGFR") -1, -2 and -3. VEGFR inhibitors play a pivotal role in blocking tumor angiogenesis. Fruquintinib was designed to have enhanced selectivity that limits off-target kinase activity, allowing for high drug exposure, sustained target inhibition, and flexibility for the potential use as part of combination therapy. Fruquintinib has demonstrated a manageable safety profile and is being investigated in combination with other anti-cancer therapies including the approved PD-1 inhibitor, sintilimab.

This presentation will report efficacy and safety data according to race for Asian and non-Asian patient subgroups from the FRESCO-2 study. FRESCO-2 is a global Phase III multi-regional clinical trial (MRCT) conducted in the U.S., Europe, Japan and Australia investigating fruquintinib plus best supportive care ("BSC") vs. placebo plus BSC in patients with previously treated metastatic colorectal cancer. There was a clinically meaningful improvement in overall survival (OS) and progression-free survival (PFS) in both Asian and non-Asian patients. The safety and efficacy subgroup analysis results were consistent with the overall FRESCO-2 population and with the established monotherapy profile of fruquintinib.

Forward-Looking Statements

This press release contains forward-looking statements within the meaning of the "safe harbor" provisions of the U.S. Private Securities Litigation Reform Act of 1995. These forward-looking statements reflect HUTCHMED's current expectations regarding future events, including but not limited to its expectations regarding the therapeutic potential of fruquintinib, surufatinib and HMPL-295, the further clinical development for fruquintinib, surufatinib and HMPL-295, its expectations as to whether any studies on fruquintinib, surufatinib and HMPL-295 would meet their primary or secondary endpoints, and its expectations as to the timing of the completion and the release of results from such studies. Forward-looking statements involve risks and uncertainties. Such risks and uncertainties include, among other things, assumptions regarding the timing and outcome of clinical studies and the sufficiency of clinical data to support approval of fruquintinib, surufatinib and HMPL-295 for the treatment of patients with colorectal cancer or other indications in jurisdictions such as China, the U.S., the E.U. or Japan, its potential to gain approvals from regulatory authorities on an expedited basis or at all; the efficacy and safety profile of fruquintinib, surufatinib and HMPL-295; assumptions regarding changes to clinical protocols or regulatory requirements; unexpected adverse events or safety issues; the ability of fruquintinib, surufatinib and HMPL-295, including as combination therapies, to meet the primary or secondary endpoint of a study, to obtain regulatory approval in different jurisdictions and to gain commercial acceptance after obtaining regulatory approval; the potential markets of fruquintinib, surufatinib and HMPL-295 for a targeted indication; the sufficiency of funding; and the impact of COVID-19 or other infectious diseases on general economic, regulatory and political conditions. In addition, as certain studies rely on the use of nab-paclitaxel, sintilimab, toripalimab, pemetrexed, platinum, etoposide or cisplatin as combination therapeutics, such risks and uncertainties include assumptions regarding their safety, efficacy, supply and continued regulatory approval. Existing and prospective investors are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof.
