In 2019, Everest acquired China rights to Nefecon from Sweden’s Calliditas Therapeutics (CALT) in an agreement worth up to $121 million. Calliditas conducted the global Phase III trial, which enrolled 364 patients randomized 1:1 for Nefecon and placebo.

Luye’s subsidiary, Boan Biotech, is running the trial together with its partner, Shanghai’s Ocumension (HK: 1477), which acquired China commercialization rights to the drug.

Shanghai Mabwell (SHA: 688062) has started a Phase I trial of 9MW301, the company’s iron homeostasis regulating macromolecular drug. The candidate is a mAb with an innovative target that Maxwell developed at its San Diego Innovation and R&D Center. In China, the mAb is a Category 1 Therapeutic Biological Product. 9MW3011 has been approved to begin trials in China and the US for two rare disease indications: β-thalassemia and polycythemia vera.

Guangzhou's Bio-Thera Solutions (SHA: 688177) has started a China Phase I trial of BAT8007, an antibody-drug conjugate (ADC) that targets Nectin-4. The trial will enroll patients with advanced solid tumors to study the safety and tolerability of BAT8007 while determining the recommended Phase II dose (RP2D) of the candidate. The trial will also evaluate the pharmacokinetics and preliminary efficacy in patients. Bio-Thera said Nectin-4 is overexpressed in urothelial carcinoma, breast cancer, non-small cell lung cancer, pancreatic cancer, esophageal cancer and head and neck cancer.

Nanjing Simcere Pharma (HK: 2096) will test its potential first-in-class anti-tumor necrosis factor receptor 2 (TNFR2) mAb with MSD's (Merck (MRK)) anti-PD-1 therapy, Keytruda (pembrolizumab) (see story). The trial, which will enroll patients with advanced solid tumors and cutaneous T-cell lymphoma (CTCL), will evaluate the safety and efficacy of SIM0235 as a monotherapy or in combination with Keytruda.
