The lung cancer drug 9291, also known as Ocitinib and known by the trade name Teresal, used to cost more, with a box costing around $51,000. Now there is a charity drug gift campaign, with a full four boxes of the drug can enjoy the free drug discount, but also cost more than 200,000. There are some places where this drug has been included in the medical insurance, such as in Shandong Province, Zhejiang Province, and Suzhou City, but it has not been widely included in many places. Ocitinib (9291), for patients with non-small cell lung cancer with EGFR gene mutation, belongs to the third generation of targeted drugs, and can be used after the first generation of drug resistance if it is effective and can significantly prolong the survival of patients. After using this drug, survival can be extended by at least maybe 10 months to about a year.
