Study of Pembrolizumab, Lenvatinib and Chemotherapy Combination in First Line Extensive-stage Small Cell Lung Cancer

A Phase II Study of Pembrolizumab, Lenvatinib and Chemotherapy Combination in First Line Extensive-stage Small Cell Lung Cancer (ES-SCLC)

• Status: Recruiting
• Phase: Phase 2
• Study type: Interventional
• Enrollment: 46 (estimated)
• Sponsor: Fundación GECP · Academic / Other
• Sex: All
• Age: 18 Years
• Healthy volunteers: Not accepted

Summary

This is a multicenter, open-label, non-randomized, single arm, 2 parts, phase II clinical trial evaluating the efficacy and safety of pembrolizumab and lenvatinib plus standard of care chemotherapy (with carboplatin and etoposide ) in subjects with histologically confirmed extensive-stage small-cell lung cancer who have not previously received systemic therapy for this malignancy.

Detailed description

A total of 85 subjects will be assigned to study treatment with pembrolizumab + lenvatinib + chemotherapy. Positive tumor programmed cell death-ligand 1 (PD-L1) expression will not be required for enrollment; however, subjects' tumors will be screened for PD-L1 expression. The primary endpoint for the Part 1 is to determine the safety of the combination. The primary endpoint for Part 2 is to determine the Progression Free survival (PFS) using RECIST 1.1. assessed by investigator. The sponsor estimates that the trial will require approximately 4 years from the time the first participant signs the informed consent until the last participant's last study-related telephone call or visit (2 years recruiting patients, 1 year of treatment and at least 1 year of follow up)

Conditions

• Small Cell Lung Cancer Extensive Stage

Interventions

Type	Name	Description
DRUG	Lenvatinib	Lenvatinib is an oral, potent multiple receptor tyrosine kinase (RTK) i that selectively inhibits VEGF-driven VEGFR2 phosphorylation and suppressed proliferation and tube formation in human umbilical vein endothelial cell models. Antitumor activity of lenvatinib in vivo has been shown in numerous xenograft animals. These results suggest that lenvatinib may be a novel anticancer therapy through inhibition of angiogenesis and may be useful as either monotherapy or in combination with other anticancer drugs. Part 1 (safety run-in) and Part 2: The study intervention consists of: Dose: 8 mg (induction) and 20 mg (maintenance) Dose Frequency: Once daily Dose formulation: Capsule Route of administration: Oral Treatment duration: 4 cycles (induction) and no treatment duration limit (maintenance).
DRUG	Pembrolizumab	Pembrolizumab is a potent humanized immunoglobulin G4 (IgG4) monoclonal antibody (mAb) with high specificity of binding to the programmed cell death 1 (PD-1) receptor, thus inhibiting its interaction with programmed cell death ligand 1 (PD-L1) and programmed cell death ligand 2 (PD-L2). Part 1 (safety run-in) and Part 2: Dose: 200 mg Frequency: Day 1, Q3W Route: Intravenous Treatment Period: Up to 35 cycles or until reaching a discontinuation criterion
DRUG	Etoposide	Standard first-line treatment for the vast majority of patients with SCLC, regardless of stage, involves combination chemotherapy with etoposide plus cisplatin or carboplatin. Pharmacotherapeutic group: Cytostatics, plant alkaloids and other natural products, derived from podophyllotoxin. Mechanism of action :The main effect of etoposide appears to be in the late S and early G2 phase of the cell cycle, in mammalian cells. Part 1 (safety run-in) and Part 2: Dose: 100 mg/m2 Frequency: Day 1-3, Q3W Route: Intravenous Treatment Period: 4 cycles
DRUG	Carboplatin	Pharmacotherapeutic group: Other antineoplastic agents, platinum compounds. Carboplatin, like cisplatin, binds to DNA to produce inter- and intra-strand cross-links cells exposed to carboplatin. DNA reactivity has been linked to cytotoxicity. Part 1 (safety run-in) and Part 2: Dose: AUC5 Frequency: Day 1, Q3W Route: Intravenous Treatment Period: 4 cycles
