QYUNS-B (02509) gained over 3% again, rising 3.26% to HK$20.9 by the time of writing, with a trading volume of HK$3.06 million. The company announced that on December 8, it received a US$5 million milestone payment from its partner Caldera Therapeutics, Inc. This payment was triggered after QX030N/CLD-423, a bispecific antibody developed by QYUNS-B, obtained ethical approval for Phase I clinical trials from the Human Research Ethics Committee (HREC) in Australia.
The company plans to initiate clinical trials for QX030N/CLD-423 in early 2026. This approval marks the official entry of QYUNS-B's bispecific antibody pipeline into the clinical stage overseas, further strengthening its leading position in autoimmune and allergic disease treatments. Both QYUNS-B and Caldera will accelerate project development to achieve more clinical progress soon.
