详细描述
This is a multicenter, open-label, dose escalation, and expansion human clinical study to observe the safety, tolerability, pharmacokinetics, and pharmacodynamics of XZP-3621 in single and multiple oral administrations in advanced NSCLC subjects with ALK rearrangement or ROS1 rearrangement, and to initially explore the efficacy of XZP-3621.The study was divided into two parts: dose escalation and dose expansion.
Dose escalation part:
The purpose of this section was to determine MTD and RP2D doses in advanced NSCLC subjects with ALK rearrangement or ROS1 rearrangement detected in tumor tissue samples or blood samples (test method is not limited).The safety and PK of single dose in human subjects in each group were first studied. After PK blood sample was collected 72 hours after single dose on day 1, continuous dose was administered once a day for 4 weeks to confirm the safety and pharmacokinetic characteristics of single dose and continuous dose.
In this study, Modified Fibonacci method was used for dose escalation. One subject was enrolled at the initial dose of 50mg. After that, according to the "3+3" dose escalation principle, the dose of 100mg (100%), 200mg (100%), 300mg (50%), 400mg (33%), 500mg (25%), 600mg (20%)and so on was incremented successively. Starting from the 100mg Qd dose group, 3 NSCLC subjects with ALK rearrangement or ROS1 rearrangement should be included per dose.If less than 3 NSCLC subjects were ALK rearrangement in any dose group due to inclusion of ROS1, and no ≥1 PR was observed in this group, additional ALK rearrangement NSCLC subjects should be added until the requirements are met. However, as long as the number of subjects in the corresponding dose group who have completed DLT observations meets the "3+3" principle of escalation, the addition of subjects to the ALK rearrangement should not affect the normal escalation of the next dose group.
Dose expansion part:

- •All previous antitumor therapies (including chemotherapy, radiotherapy and immunotherapy) have been stopped for at least 4 weeks before the first administration of XZP-3621 (in which nitrosoreas or mitomycin should be stopped for≥ 6 weeks, and oral small molecule targeted therapy drugs and Chinese medicine (including decoction or Chinese patent medicine) should be stopped for at least 2 weeks);Palliative radiation therapy (irradiation of non-target lesions, local administration of non-target lesions) for the purpose of relieving local symptoms was allowed to be completed one week before study enrollment;
- •The expected survival was determined by the investigator to be 12 weeks or more;
- •At the time of enrollment, the subject's organ function at baseline was good, and the laboratory data met the following criteria:
- •Blood routine: Absolute Neutrophils Count≥1.5*109/L、PLT≥90*109/L、HGB≥90g/L;

- •AMS≤ULN (If AMS is elevated, between 1 and 2 times of ULN, but there are no other signs and clinical evidence of pancreatic disease, the subject can be included);
- •HbA1c≤ 7.0%;
- •The fertile male or female subject must agree to use an effective contraceptive method, such as a double-screen contraceptive method, a condom, oral or injectable contraceptive, an intrauterine device, etc. during the study period and within 90 days of the last dose of XZP-
