Dec 22, 2025 —Laekna, Inc. (2105.HK) today announced that following the positive results observed in the Phase I MAD study, the company has commenced study recruitment in Phase I Multiple Dose Expansion study of LAE102 in China for the treatment of obesity and the first subject has been dosed.

The Phase I Multiple Dose Expansion study is a randomized, double-blind, placebo-controlled study to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of LAE102, administered subcutaneously, in 60 overweight/obese subjects. Enrolled subjects will be randomized into LAE102 or placebo for a 6-month treatment.

The preliminary results of the Phase I MAD study of LAE102 (administered subcutaneously weekly for 5 weeks) demonstrated an encouraging trend towards lean body mass increase and fat mass reduction, a well-tolerated safety profile and robust PK/PD (Read more). The pre-planned study was initiated to further evaluate the efficacy and safety profile of LAE102 over a longer treatment duration (6 months).

About LAE102

LAE102 is an internally discovered monoclonal antibody selectively targeting ActRIIA, a receptor that plays an important role in muscle regeneration and lipid metabolism. In the pre-clinical models, LAE102 has been shown to increase lean mass and decrease fat mass. In combination with GLP1R agonist, LAE102 can further reduce fat mass and significantly regain the lean mass loss induced by GLP1R agonist. This positions LAE102 as a promising drug candidate for achieving quality weight control.

About Laekna

Stock Code: 2105.HK

Laekna is a science-driven, clinical-stage biotechnology company committed to bringing novel therapeutics to patients with metabolic diseases, cancer and liver fibrosis around the world.

As of June 30, 2025, Laekna has initiated seven clinical trials for LAE102, LAE002 (afuresertib) and other drug candidates to address unmet medical needs in obesity and cancers.

LAE102 is our internally discovered antibody against ActRIIA. Blocking Activin-ActRII pathway could promote muscle regeneration and decrease fat mass, this positions LAE102 as a promising drug candidate for achieving quality weight control. We are advancing the Phase I clinical trials for obesity indication in both China and the U.S. In November 2024, Laekna entered into a clinical collaboration agreement with Eli Lilly and Company to support and accelerate global clinical development of LAE102 for the treatment of obesity.

In addition to LAE102, LAE103 is our internally discovered ActRIIB-selective antibody, LAE123 is an ActRIIA/IIB dual antagonistic monoclonal antibody. Laekna has established a comprehensive ActRII portfolio and is actively advancing these drug candidates to clinical studies as novel therapies for muscle and other disease indications.

In the cancer area, Laekna has built a comprehensive portfolio of drug candidates including LAE002(afuresertib), LAE001 and other clinical and pre-clinical drug candidates. LAE002 (afuresertib) is a potent AKT inhibitor that inhibits all three AKT isoforms (AKT1, AKT2 and AKT3) as well as one of the only two AKT inhibitors in late-stage development for breast and prostate cancer globally. Laekna has commenced the Phase III clinical trial (AFFIRM-205) for LAE002 in patients with HR+/HER2- breast cancer and the study recruitment is on track.

Laekna, Inc. (2105.HK) was listed on the Main Board of The Stock Exchange of Hong Kong Limited (the “Hong Kong Stock Exchange”) on June 29, 2023.
