Details and patient eligibility

About

This trial is a Phase II trial designed to evaluate the safety and efficacy of using oral AL8326 , a multi-targeted receptor Tyrosine Kinase Inhibitor( TKI) , to recurrent, advanced, or metastatic small cell lung cancer (SCLC) patients who need ≥2nd line treatment .

Full 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.

Enrollment: 36 estimated patients

Sex: All

Ages: 18+ years old

---

36 participants in 3 patient groups

OBD finding cohort at low dose

Experimental group

Description:

Subject in low dose group will receive AL8326 orally in each cycle until intolerable toxicity or disease progression or withdrawal . 6-12 subjects are in this group. Efficacy, safety and PK will be evaluated and compared within 3 different dosing group to define the final OBD.

Treatment:

Drug: AL8326 low dose group

OBD finding cohort at middle dose

Experimental group

Description:

Subject in middle dose group will receive AL8326 orally in each cycle until intolerable toxicity or disease progression or withdrawal . 6-12 subjects are in this group. Efficacy, safety and PK will be evaluated and compared within 3 different dosing group to define the final OBD.

Treatment:

Drug: AL8326 middle dose group

OBD finding cohort at high dose

Experimental group

Description:

Subject in high dose group will receive AL8326 orally in each cycle until intolerable toxicity or disease progression or withdrawal . 6-12 subjects are in this group. Efficacy, safety and PK will be evaluated and compared within 3 different dosing group to define the final OBD.

Treatment:

Drug: AL8326 high dose group
