BRM421, a new drug for treating Dry Eye Disease, receives approval to proceed to Phase 2 clinical trials in China

Taipei, Taiwan, 18th Apr 18, 2023, BRIM Biotechnology, Inc. (“BRIM”, TPEx 6885) announced that BRM421 for the treatment of dry eye disease, licensed out to Grand Pharmaceutical Group Limited (Grand Pharmaceutical) for the China region, has been approved by the China National Medical Products Administration (NMPA) to conduct Phase 2 clinical trials. The trial is a single-arm, open-label clinical study that aims to recruit no more than 40 patients with moderate to severe dry eye disease and to evaluate the efficacy and safety of BRM421 in treating these patients.

The ophthalmology market in China is expanding, with a compound annual growth rate (CAGR) of 9.3% from USD 1.8 billion in 2015 to USD 2.6 billion in 2019. It is estimated to accelerate at a CAGR of 18.6% from 2019 to 2025 and reach a market size of USD 7.2 billion by 2025. The market size of dry eye disease in China has grown from USD 272 million in 2015 to USD 430 million in 2019, with a CAGR of 12.2%. It is estimated to grow at a CAGR of 28.4% from 2019 to 2030 and potentially reach USD 6.7 billion by 2030.

BRM421 is a new peptide drug for treating dry eye disease developed from BRIM’s pigment epithelial-derived factor (PEDF) peptide platform (PDSP). It has a novel mechanism of action that can promote the proliferation of limbal stem cells and achieve corneal regeneration and repair. Data from completed Phase 2 clinical trials showed that BRM421 has a significant effect on symptoms after one week of treatment and is well tolerated with a good safety profile, giving it a significant advantage in the market competition. BRIM hopes to launch the drug in China as soon as possible through its collaboration with Grand Pharmaceutical and provide an affordable and effective treatment option for dry eye disease patients.

After licensing the commercial development rights in China, Hong Kong, and Macau to Grand Pharmaceutical in 2019, BRIM has been continuously developing BRM421. A multicenter, double-blind, randomized, vehicle-controlled Phase 3 clinical trial is ongoing in the United States. The US trial aims to recruit over 700 patients with moderate to severe dry eye disease, with topline results expected in Q4 2023, subject to enrollment status.
