Ribo Life Science Co. Ltd.’s HK$1.8 billion (US$230 million) raise on Jan. 9 was the sole Chinese biotech IPO on the Hong Kong Stock Exchange in the first quarter (Q1) of 2026, despite a growing backlog of more than 70 filings from China life science firms in 2025. Among med-tech companies, Hangzhou Diagens Biotechnology Co. Ltd. debuted with a $101 million Hong Kong IPO March 30, 2026.

Homozygous deletion of methylthioadenosine phosphorylase (MTAP), present in ~15% of tumors, leads to accumulation of methylthioadenosine and partial inhibition of protein arginine methyltransferase 5 (PRMT5), creating a synthetic-lethal vulnerability that sensitizes tumors to PRMT5-targeted therapies. Researchers from Beone Medicines Ltd. presented preclinical efficacy data of BGB-58067, an MTA-cooperative PRMT5 inhibitor, in models of tumors with MTAP-deficiency.

An advantage of antibody-drug conjugates (ADCs) is that they allow targeted delivery of cytotoxic agents into tumors, thus improving the therapeutic index. Pfizer Inc. has developed a new ADC, PF-08046033, that contains auristatin S (AurS) as the cytotoxic payload and targets transmembrane glycoprotein NMB (GPNMB).

Neomorph Inc.’s NEO-811 is a molecular glue degrader designed to induce targeted degradation of ARNT and suppress this signaling pathway implicated in clear cell renal cell carcinoma (ccRCC). Targeting ARNT offers a complementary strategy to broadly disrupt oncogenic HIF signaling in ccRCC.

Minimal residual disease (MRD) has become a central concept in modern oncology, reshaping how clinicians evaluate response, relapse risk and treatment precision. As increasingly sensitive technologies reveal traces of cancer that persist after therapy, MRD is emerging as both a biological challenge and a clinical opportunity, especially as new data illuminate its complexity across hematologic and solid tumors. This topic was addressed at the 2026 American Association for Cancer Research (AACR) annual meeting.
