The process of manufacturing autologous T-cell therapies is technically challenging when compared with other oncology drugs, making the overall cost of developing CAR T therapies significantly higher. A challenging reimbursement environment for drugs listed on China’s National Reimbursement Drug List also means that most patients will have to pay out of pocket to access CAR T therapies. Taken together, complex logistics – production, manufacturing and supply chain – and complicated administration requirements are key bottlenecks that inflate the input costs involved in developing these specialized treatment options.
China’s National Medical Products Administration has cleared Immuneonco Biopharmaceuticals Co. Ltd.’s’ IMM-01 (timdarpacept) to enter a pivotal phase III trial in combination with Beigene Co. Ltd.’s PD-1 inhibitor, tislelizumab, in relapsed or refractory classical Hodgkin lymphoma patients who relapsed or progressed after treatment with PD-1 inhibitors.
Suzhou, China-based Kintor Pharmaceutical Ltd. reported positive findings from a phase II study of GT-20029, a topical therapy for male androgenetic alopecia, on April 21 – boosting both the company’s stock and its chances of a late-stage clinical study in China and the U.S.
Genfleet Therapeutics Inc. has entered the KRAS G12C inhibitor race in the U.S. as it gears up to begin phase III trials of GFH-925 (IBI-351) in patients with refractory metastatic colorectal cancer (CRC) following FDA clearance.
The timing is ripe for a robust biosimilar market in China, given the rapid increase of novel biologics approved to treat cancer and inflammatory diseases in the country over the past decade and the looming patent cliffs for several established biologics. As of December, the NMPA had approved more than 20 biosimilars that were developed in China. Most of those referenced just two biologics – Roche AG’s cancer drug Avastin (bevacizumab) and Abbvie Inc.’s immunology drug Humira (adalimumab). In 2022, the oncology and immunology biosimilar market in China garnered sales of about $2 billion, according to Clarivate estimates. To reach their full potential in China though, biosimilars must win over prescribers and patients.
Follow-on biologic makers in China have been working to capitalize on looming patent cliffs of blockbuster biologics. Advancing biosimilars of denosumab (Prolia/Xgeva; Amgen Inc.) and semaglutide are the latest examples.
Sino Biopharmaceutical Ltd. and Boehringer Ingelheim International GmbH are partnering to develop innovative cancer therapies in mainland China. They will jointly develop and commercialize three clinical Boehringer assets, including brigimadlin, zongertinib, BI-764532, and other unnamed early stage assets.
Medicxi has made its first ever investment in China – and its biggest single commitment to date – putting $40 million into D3 Bio Inc. The investment by the London-based venture capital firm will accelerate development of D3’s lead program D3S-001, a second generation KRAS G12C inhibitor, which is in phase II development in advanced solid tumors.
After reviewing data from its phase II trial of farnesoid X receptor agonist ASC-42 in primary biliary cholangitis, Ascletis Pharma Inc. said it was quitting development of the molecule in all indications.
Biosimilar competition to Amgen Inc.’s denosumab (Prolia/Xgeva) is rising globally, with Mabwell (Shanghai) Bioscience Co. Ltd. gaining the latest China NMPA approval of Maiweijian (TK-006) on April 8. Mabwell’s wholly owned subsidiary, Jiangsu T-mab Biopharma Co. Ltd., gained NMPA clearance of Maiweijian (120 mg) as the first denosumab biosimilar for the indications of U.S.-licensed Xgeva for bone-related diseases.
