Clinical Trials for Small Cell Lung Cancer

Open-label, Non-randomized, Multi-cohort, Phase 1b/2 Trial Investigating the Safety, Tolerability, and Antitumor Activity of STC-15 (a METTL3 Inhibitor) as a Part of Combination Therapy With Toripalimab in Participants With Selected Advanced Cancers

High burden on patient

The trial has a high burden on patients. An example would be a phase 1 trial with extra tumor biopsies and frequent pharmacokinetic blood draws.

TrialFetch AI summary: This trial enrolls adults with advanced or metastatic NSCLC, melanoma, endometrial cancer, or HNSCC who have progressed after standard therapies including prior anti-PD-1/L1 agents, and evaluates the combination of STC-15 (an oral METTL3 inhibitor targeting RNA methylation) plus toripalimab (anti-PD-1 antibody). Eligible patients must have measurable disease, ECOG 0–1, and no active CNS disease.

Study of NMS-03305293, a Non-Trapping PARP1-Specific PARP Inhibitor in Relapsed Small Cell Lung Cancer

High burden on patient

The trial has a high burden on patients. An example would be a phase 1 trial with extra tumor biopsies and frequent pharmacokinetic blood draws.

TrialFetch AI summary: Adults with extensive-stage SCLC relapsing within 6 months after platinum–immunotherapy (and after tarlatamab if appropriate), up to three prior lines, receive oral NMS-03305293 (a PARP1-selective, non-trapping PARP inhibitor) continuously with temozolomide days 1–5 of 28‑day cycles. Single-arm study focuses on safety/PK and preliminary activity in this heavily pretreated population with measurable disease and ECOG 0–2.

Study of Trilaciclib and Lurbinectedin in Small Cell Lung Cancer

Moderate burden on patient

The trial has a moderate burden on patients. An example would be a trial testing an IV drug, with scans every 8 weeks which would be more frequent than standard of care.

Started >3 years ago

The trial was activated more than 3 years ago. This is not always bad but can indicate that the trial has less current treatments, or has had trouble getting enough patients to enroll due to other issues.

TrialFetch AI summary: Adults with extensive-stage SCLC that has progressed after prior platinum and PD-1/PD-L1 therapy (ECOG 0–1, measurable disease) receive lurbinectedin plus trilaciclib. Lurbinectedin is a DNA-binding transcription inhibitor; trilaciclib is a transient CDK4/6 inhibitor given to protect hematopoietic stem/progenitor cells and reduce severe myelosuppression while assessing antitumor activity.

ClinicalTrials.gov ID: NCT05578326

A Single Arm Phase II Study Assessing Efficacy of Stereotactic Radiosurgery (SRS) for Brain Metastasis (BM) From Small Cell Lung Cancer (SCLC)

The trial has a moderate burden on patients. An example would be a trial testing an IV drug, with scans every 8 weeks which would be more frequent than standard of care.

Started >3 years ago

The trial was activated more than 3 years ago. This is not always bad but can indicate that the trial has less current treatments, or has had trouble getting enough patients to enroll due to other issues.

TrialFetch AI summary: Adults with histologically confirmed SCLC and up to 10 brain metastases (KPS 60–100/ECOG 0–2), without prior brain RT or leptomeningeal disease, receive stereotactic radiosurgery to all lesions. Designed to evaluate intracranial control and short-term survival (6-month OS) with focal SRS instead of whole-brain radiotherapy.

ClinicalTrials.gov ID: NCT05419076

A Randomized, Multi-Cohort Phase II Trial of Temozolomide and Atezolizumab as Second or Third Line Treatment for Small Cell Lung Cancer

Moderate burden on patient

The trial has a moderate burden on patients. An example would be a trial testing an IV drug, with scans every 8 weeks which would be more frequent than standard of care.

Started >3 years ago

The trial was activated more than 3 years ago. This is not always bad but can indicate that the trial has less current treatments, or has had trouble getting enough patients to enroll due to other issues.

TrialFetch AI summary: Adults with extensive-stage SCLC progressing after platinum-based chemoimmunotherapy (chemo-sensitive or -resistant), ECOG 0–2, measurable disease, and no prior temozolomide are randomized to atezolizumab (anti–PD-L1) plus temozolomide with either a 5-day or extended 14–21 day oral schedule. Stable, asymptomatic brain metastases are allowed; outcomes include response rate, PFS (including intracranial), OS, and safety.

ClinicalTrials.gov ID: NCT04919382

RAndomized Phase II/III Trial of Consolidation Radiation + Immunotherapy for ES-SCLC: RAPTOR Trial

Moderate burden on patient

The trial has a moderate burden on patients. An example would be a trial testing an IV drug, with scans every 8 weeks which would be more frequent than standard of care.

Started >3 years ago

The trial was activated more than 3 years ago. This is not always bad but can indicate that the trial has less current treatments, or has had trouble getting enough patients to enroll due to other issues.

TrialFetch AI summary: Adults with extensive-stage SCLC who have not progressed after 4–6 cycles of platinum/etoposide plus atezolizumab (PR/SD), ECOG 0–2, ≤3 liver mets, and controlled brain mets are randomized to maintenance atezolizumab alone versus atezolizumab plus consolidation external-beam radiotherapy to all disease sites. Atezolizumab is an anti–PD-L1 monoclonal antibody; the study tests whether adding consolidation RT improves PFS/OS versus maintenance alone.

A Phase II Trial of Lamivudine in Combination With Chemoimmunotherapy in Patients With Extensive Stage SCLC

Moderate burden on patient

The trial has a moderate burden on patients. An example would be a trial testing an IV drug, with scans every 8 weeks which would be more frequent than standard of care.

Started >3 years ago
