**Press Release**

**HUTCHMED Completes Patient Enrollment of Phase II Registration Trial of Amdizalisib in Follicular Lymphoma in China**

**Hong Kong, Shanghai & Florham Park, NJ — Monday, February 27, 2023:** HUTCHMED (China) Limited ("<u>HUTCHMED</u>") (Nasdaq/AIM:HCM, HKEX:13) today announces that it has completed patient enrollment of Phase II registration trial of amdizalisib in patients with relapsed or refractory follicular lymphoma ("FL"), a subtype of non-Hodgkin's lymphoma ("NHL"). The last patient was enrolled on February 24, 2023.

The clinical trial is a multi-center, single-arm, open-label clinical study to evaluate the efficacy and safety of amdizalisib once a day oral monotherapy in patients with relapsed/refractory FL or marginal zone lymphoma ("MZL"). The primary endpoint is objective response rate ("ORR"), with secondary endpoints including complete response rate (CRR), progression-free survival (PFS), time to response (TTR) and duration of response (DoR). A total of 108 relapsed/refractory FL patients were enrolled. The trial is being conducted in over 35 sites in China. Additional details may be found at clinicaltrials.gov, using identifier <u>NCT04849351</u>.

Topline results on the FL patients in this trial are expected to be reported in the second half of 2023, followed by submission of results for presentation at an appropriate medical conference. If positive, HUTCHMED would initiate plans to apply for marketing authorization of amdizalisib for relapsed/refractory FL from the China National Medical Products Administration (NMPA).

**About PI3Kδ and NHL**

PI3Kδ (phosphoinositide 3-kinase delta) is a lipid kinase that controls the activation of several important signaling proteins. Upon an antigen binding to B-cell receptors, PI3Kδ can be activated through the Lyn and Syk signaling cascade. The abnormal activation of B-cell receptor signaling is closely related to the development of B-cell type hematological cancers, which represent approximately 85% of all NHL cases. Therefore, PI3Kδ is a target for drugs that aim to prevent or treat hematologic cancer.

FL accounts for approximately 17% of NHL and MZL accounts for approximately 8% of NHL. In the U.S., there were estimated 13,000 and 6,000 new cases of FL and MZL in 2020, respectively. In China, there were estimated 16,000 and 7,000 new cases of FL and MZL in 2020, respectively.<sup>1,2,3</sup>

**About Amdizalisib** 

Amdizalisib (HMPL-689) is a novel, selective and potent oral inhibitor targeting the isoform PI3Kδ. Amdizalisib's pharmacokinetic ("PK") properties are favorable with good oral absorption, moderate tissue distribution and low clearance in preclinical PK studies, suggesting a low risk of drug accumulation and drug-to-drug interaction. Because of its high target selectivity and optimal PK profile, amdizalisib has the potential to demonstrate an optimal benefit-risk profile in this class.

In addition to the current Phase II trial and the supportive Phase I trial in China, amdizalisib is also being evaluated in combination with tazemetostat (a methyltransferase inhibitor of EZH2) in patients with relapsed or refractory lymphoma in a Phase II study in China.

HUTCHMED currently retains all rights to amdizalisib worldwide.
