Summary

This is a prospective, single-arm, single-center Phase II clinical study. In this study, participants will receive Ivosidenib in combination with CapeOX chemotherapy and radiotherapy. The treatment regimen is as follows: participants will first receive Ivosidenib in combination with CapeOX chemotherapy during the first cycle, followed by radiotherapy starting 2 weeks after medication. Depending on the dose limits of normal tissue radiation, Stereotactic Ablative Radiotherapy (SABR), large fraction radiotherapy, or high-dose combined with low-dose radiotherapy will be administered to primary and metastatic lesions. One week after completing radiotherapy, participants will continue to receive Ivosidenib in combination with CapeOX systemic treatment. If extensive primary and metastatic lesions cannot be treated with radiotherapy initially, participants will continue to receive Ivosidenib in combination with CapeOX systemic treatment until the lesions shrink, at which point radiotherapy may be considered.

Assessments will be conducted every 2 treatment cycles after treatment initiation, with multidisciplinary team (MDT) discussions to determine if No Evidence of Disease (NED) is achieved. Patients achieving NED may undergo surgery or local treatment, while those with stable or partial responses will continue combination therapy. Patients with disease progression will discontinue study treatment. Patients ineligible for surgical treatment will continue combination therapy until disease progression or until they exit the study for surgical treatment.

During the study period, participants will undergo safety monitoring. The safety follow-up period is defined as 90 days after the last dose of Ivosidenib. Safety data will be collected from the time of informed consent signing until the end of the safety follow-up period or initiation of new anti-tumor treatment (whichever occurs first).

Ivosidenib (AK112)

Participants will receive Ivosidenib in combination with CapeOX chemotherapy and radiotherapy. Participants will first receive Ivosidenib in combination with CapeOX during the first cycle, followed by radiotherapy starting 2 weeks after medication. Depending on the dose limits of normal tissue radiation, Stereotactic Ablative Radiotherapy (SABR), large fraction radiotherapy, or high-dose combined with low-dose radiotherapy will be administered to primary and metastatic lesions. One week after completing radiotherapy, participants will continue to receive Ivosidenib in combination with CapeOX systemic treatment. If primary and metastatic lesions are too extensive for initial radiotherapy, participants will continue to receive Ivosidenib in combination with CapeOX systemic treatment until the lesions shrink, at which point radiotherapy may be considered.。
