Clinical Trial Summary

This is an open-label, randomized, multi-cohort, multi-center, phase Ib/II study to evaluate the safety and efficacy of Adebrelimab plus Irinotecan Liposome (II) with or without Famitinib in patients with extensive-stage small cell lung cancer (ES-SCLC) pre-treated with immune checkpoint inhibitor(s).

Description:

This study is divided into two stages. Dose exploration will be conducted first, and after obtaining preliminary safety data it will be decided by investigator when to proceed with dose extension. The aim of this study is to observe and evaluate the safety and efficacy of Adebrelimab plus Irinotecan Liposome (II) with or without Famitinib.

3. Renal function: Serum creatinine=1.5×ULN or creatinine clearance=50ml/min (Cockcroft-Gault formula).

4. Normal coagulation function: INR and APTT=1.5×ULN.

5. TSH=ULN.

6. Other: Lipase=1.5×ULN (Patients with lipase>1.5×ULN but no clinical or imaging evidence of pancreatitis could be enrolled); Amylase=1.5×ULN (Patients with amylase >1.5×ULN but no clinical or imaging evidence of pancreatitis could be enrolled); ALP=2.5×ULN (Patients with bone metastasis, ALP=5×ULN).

7. Doppler ultrasound evaluation: left ventricular ejection fraction (LVEF)=50%.

• Women of childbearing potential must undergo a negative pregnancy test (HCG) 7 days prior to initiation of treatment, and women of childbearing potential and men (who are sexually active with women of childbearing potential) must agree to use effective contraception uninterruptedly for the duration of the treatment period and for 3 months after the administration of the last therapeutic dose.

Exclusion Criteria:

• With active tuberculosis or tuberculosis under treatment.

• Congenital or acquired immunodeficiency, such as human immunodeficiency virus (HIV) infection. Untreated active hepatitis B (HBsAg positive or HBV DNA=500 IU/ml with abnormal liver function), hepatitis C (hepatitis C antibody positive, with higher HCV-RNA than the lower detection limit of the assay method and abnormal liver function) or hepatitis B and C co-infection.

• Hypertension that cannot be controlled with medications (systolic blood pressure=140 mmHg or diastolic blood pressure=90 mmHg). History of hypertensive crisis or hypertensive encephalopathy.

• Arteriovenous thrombosis events occurred within 24 weeks prior to signing the ICF, such as cerebrovascular accidents (including temporary ischemic attacks, cerebral hemorrhage, cerebral infarction), deep vein thrombosis, and pulmonary embolism.

• With factors influencing absorption of drug, such as refractory nausea and vomiting, chronic gastrointestinal diseases, or inability to swallow the formulated product.
