How long does it take for Sotorasib to take effect?

The time to onset of response to Sotorasib varies based on individual differences, tumor characteristics, and disease progression prior to treatment. Generally speaking, in the early stages of using sotorasiib, some patients may observe positive effects within a short period of time after treatment, but in other patients, the effects may take longer to appear.

Sotoraxib is a targeted therapeutic drug. Its mechanism of action is to inhibit the activity ofKRAS G12C mutant and block abnormal signaling pathways, thereby interfering with the proliferation and spread of cancer cells. This process may result in gradual shrinkage or stabilization of the tumor, as reflected in imaging studies or clinical symptoms.

In clinical trials, significant anti-tumor activity is observed in some patients within a short period of time, while others may require more time to see similar effects. Therefore, the exact duration of treatment with sotoraxib cannot be determined and should be determined based on the patient's specific condition and physician's assessment.

Patients should pay close attention to their physical condition while using sotoraxib, and conduct regular examinations and monitoring as recommended by their doctors. Doctors may use various tests, such as imaging studies or laboratory tests, to evaluate the drug's effectiveness and the patient's overall response. During the treatment process, patients should also promptly report any uncomfortable symptoms to the doctor so that the doctor can make timely adjustments and management.

The original drug of sotorasibu has not yet been launched in China, so patients cannot purchase it domestically and need to purchase sotorasibu through overseas channels. The price of the original version of sotorasibu in Hong Kong, China, with the specifications of 120mg*240 tablets, is around 8 million, and the price of the European version of the original drug with the same specifications is around 4 million, which is relatively expensive. The cheaper ones are the generic drugs marketed abroad. For example, the price of generic drugs in Laos and Bangladesh is around two to three thousand yuan. The price is relatively cheap, and the ingredients of foreign generic drugs are basically the same as the original drugs.
