Evaluation of the safety and efficacy of the drug AL8326 in the post-first treatment of small cell lung cancer.

Phase 2

Active, not recruiting

• Conditions: Small Cell Lung Cancer (SCLC) patients who need ≥2nd line treatment without or with brain metastasis which is controlled with no active hemorrhage.

• Registration Number: 2023-509067-24-01
• Lead Sponsor: Advenchen Pharmaceuticals LLC

Brief Summary

To determine the optimal biological dose (OBD) based on efficacy and safety of each dosing group.

ORR for all dosing groups and OBD group plus expansion cohort for = or >2nd line treatment of AL8326 for SCLC patients.

Detailed Description

This study is designed for two steps: Phase 2 Optimal Biological Dose (OBD) finding and Phase 2 expansion cohort study after OBD determination.

The Phase 2 study aims to find optimal biological dose (OBD) initially. Patients will be randomized to 3 different dosing groups in OBD finding cohorts. Each cohort will enroll 6-12 SCLC patients who need ≥2nd line treatment without or with brain metastasis which is controlled with no active hemorrhage. This OBD finding cohort will also evaluate the pharmacokinetic profile of AL8326.

A phase 2 expansion cohort will be continued if a positive clinical result would have been observed after OBD determination for 40-60 patients. Upon FDA's approval the Phase 2 expansion cohort clinical study will be further expanded to evaluate the safety and efficacy of AL8326 in patients individually with SCLC who need = or \>2nd line treatment without or with brain metastasis which is controlled with no active hemorrhage.
