Clinical Trial Summary

This is a multicenter, randomized, double-blind, placebo-controlled, phase III study to evaluate the efficacy and safety of AL8326 tablets in small cell lung cancer (SCLC) patients with disease progression or recurrence after receiving at least second-line treatment regimens.

Description:

There are 2 treatment groups in this trial, and the study population, sample size and basic design of each group are:

Patients with pathologically confirmed small cell lung cancer at baseline and need = or >3rd line treatment : the sample size was expected to be 243 cases, 162 in the active group and 81 in the control group.

Subjects will be randomized in a 2:1 ratio under double-blind conditions into two groups, with the active group receiving the trial drug AL8326 tablets and the control group receiving placebo. AL8326 tablets and placebo are administered as follows: oral administration, once daily for 28 days per cycle until intolerable toxicity or established disease progression or death or voluntary withdrawal or up to 12 months ( approximately 13 cycles) of treatment. Subjects will have a final visit, followed by a long-term follow-up period, and the tumor disease status will be determined according to RECIST 1.1.

7. Previously received cytotoxic chemotherapy and/or immunotherapy, and the end of the last dose is at least 4 weeks apart from the first dose of study drug; the end of anti- tumor herb medicine is at least 14 days apart; the end of nitroso or mitomycin was at least 6 weeks apart, and tyrosine kinase inhibitors (TKIs) class molecular targeted drugs were at least 4 weeks apart; the treatment of brain metastases/bone metastases had to be at least 2 weeks apart; and had recovered to = Grade 1 from the toxicity of previous treatment [except for the following: a. alopecia; b. long-term toxicity caused by radiotherapy, which could not be recovered in the judgment of the investigator; c. platinum-induced Grade 2 and the following neurotoxicity such as hearing impairment (according to the Common Terminology Criteria for Adverse Events CTCAE V5.0)];

8. Had arterial thrombosis or severe venous thromboembolic events within 6 months before screening, such as cerebrovascular accident (including transient ischemic attack), deep venous thrombosis and pulmonary embolism;

17. Having a history of organ transplantation or being prepared to undergo organ transplantation;

18. Other reasons that, in the discretion of the investigator, would make participation in this study inappropriate.

Notes:

*1 new line of therapy refers to a change in treatment regimen due to disease progression rather than toxicity or other reasons; after progression on the first treatment, reuse of the same treatment regimen is also a new line of therapy;

** Lesions treated with radiotherapy or locoregional therapy must have radiographic evidence of disease progression to be considered target lesions. If there is only one measurable lesion, the lesion cannot be brain lesion.
