China has the highest incidence of gastric cancer (gastric and gastroesophageal junction adenocarcinoma) in the world, and therapeutic options are limited. Only two targeted agents are approved to treat this indication: Roche’s Herceptin and Jiangsu Hengrui Medicine’s AiTan. Herceptin is the first-line standard of care for HER2-positive patients and AiTan is approved for third-line patients, irrespective of HER2 status. Several novel targeted therapies—including angiogenesis inhibitors (Eli Lilly’s Cyramza and Chi-Med’s Elunate); a claudin inhibitor (Ganymed’s zolbetuximab), and combination regimens of PD-1/PD-L1 inhibitors (Bristol-Myers Squibb’s Opdivo, Merck & Co.’s Keytruda, Innovent Biologics’ Tyvyt, and Suzhou Jiangsu Hengrui Medicine’s camrelizumab);—and biosimilars of Herceptin are in late-stage development. The launch and uptake of these novel therapies will lead to significant growth of the gastric cancer therapy market over the 2018-2028 forecast period. However, the need for additional, effective targeted therapies will remain high, representing a lucrative commercial opportunity for drug developers.

  • How large is China’s drug-treatable gastric cancer population, and how will the drug-treatment rate change during the forecast period?
  • Which are the most commercially relevant drugs in China’s gastric cancer market and why? What are interviewed experts’ insights on current treatment options? Which clinical needs remain unfulfilled?
  • What are the key market access considerations for key therapies in the gastric cancer pipeline? What sales / uptake could they secure in and what are interviewed experts’ opinions of key emerging therapies?
  • What are the key drivers and constraints in China’s gastric cancer therapy market, and how will the market evolve over the forecast period?
