Radiopharma-focused Aktis Oncology Inc. priced its recently upsized IPO, selling 17.65 million shares at $18 apiece, the high end of its pricing range, raising gross proceeds of $318 million, a hopeful sign that 2026 might signal an opening of the IPO window for biopharma.
Nectin-4 is a cell-adhesion molecule that is highly expressed in several malignancies, including bladder, colorectal, lung and breast cancers, while exhibiting minimal expression in most normal adult tissues.
Corbus Pharmaceuticals Inc. has placed its chips on “bets where somebody else is ahead of us,” CEO Yuval Cohen said. “The idea is to have a de-risked asset” that proves better in the clinic. At the 2025 American Society of Clinical Oncology Genitourinary (ASCO GU) Cancers Symposium in San Francisco, Corbus offered data from the U.S. and U.K. first-in-human dose-escalation study – the Western trial – with Nectin-4-targeting antibody-drug conjugate (ADC) CRB-701 (SYS-6002).
Celltrion Inc. posted preclinical study results of two new antibody-drug conjugate (ADC) candidates – CT-P70 and CT-P71 – at the World ADC 2024 conference in San Diego Nov. 6, with plans to move the assets into clinical trials. Poster presentations of both ADC candidates “drew significant attention from the attendees” at the oncology meeting, Incheon, South Korea-based Celltrion said, while highlighting its efforts to transition from a biosimilar maker to a novel therapy developer.

Innate Pharma SA has obtained IND clearance from the FDA for IPH-4502, its novel and differentiated topoisomerase I inhibitor antibody-drug conjugate (ADC) conjugated to exatecan targeting Nectin-4 in solid tumors. In nonclinical models, IPH-45 was well tolerated and showed antitumor efficacy in vitro and in vivo.
Researchers from Adcentrx Therapeutics Inc. recently reported preclinical data for the Nectin-4-targeting antibody-drug conjugate (ADC) ADRX-0706, currently in phase I development for the treatment of solid tumors (NCT06036121).
Shares of Corbus Pharmaceuticals Inc. (NASDAQ:CRBP) doubled on opening Jan. 26 and ended the day up a whopping 249% as investors got a look at data from a first-in-human study testing next-generation Nectin-4-targeted antibody-drug conjugate (ADC) CRB-701. Licensed from CSPC Pharmaceutical Group for $7.5 million up front in February 2023, CRB-701 has IND clearance from the U.S. FDA, and Corbus plans to start its own clinical testing in the first quarter of 2024.
Nectin cell adhesion molecule 4 (Nectin-4) overexpression in different tumors correlates with cancer progression and poor prognosis in many human malignancies. The first Nectin-4-targeting antibody, enfortumab vedotin (EV), has limited efficacy and frequent adverse effects in several solid tumors. Researchers at Mabwell (Shanghai) Bioscience Co. Ltd. and colleagues have now reported on the generation and characterization of 9MW-2821, an antibody-drug conjugate consisting of an antibody targeting Nectin-4 conjugated to monomethyl auristatin E (MMAE).
