Metronomic Oral Paclitaxel Plus PD-1/ PD-L1 Inhibitor Maintenance in Advanced Lung Cancer (PULSE Study) (PULSE)

2026年8月2日 更新者:Yue-Yin Pan、Anhui Provincial Cancer Hospital

Efficacy and Safety of Metronomic Oral Paclitaxel Plus an Immune Checkpoint Inhibitor as Maintenance Therapy After First-Line Induction in Advanced Squamous Non-Small Cell Lung Cancer and Extensive-Stage Small Cell Lung Cancer: A Multicenter, Multi-Cohort Exploratory Study

This study will evaluate the efficacy and safety of metronomic oral paclitaxel combined with a PD-1 or PD-L1 inhibitor as maintenance therapy in patients with advanced lung cancer whose disease has not progressed after first-line chemoimmunotherapy.

The study will include two independently analyzed cohorts. Cohort A will include patients with advanced squamous non-small cell lung cancer(sqNSCLC), and Cohort B will include patients with extensive-stage small cell lung cancer(ES-SCLC). All participants will receive oral paclitaxel three times weekly together with the same immune checkpoint inhibitor used during first-line induction therapy, whenever feasible.

The primary outcome is progression-free survival. Other outcomes include tumor response, overall survival, adverse events, treatment tolerability, and quality of life. Approximately 107 participants will be enrolled across multiple study centers.

詳細な説明

Immune checkpoint inhibitor-based chemoimmunotherapy is a standard first-line treatment for advanced squamous non-small cell lung cancer and extensive-stage small cell lung cancer. However, many patients experience disease progression shortly after completing the chemotherapy component and entering the maintenance phase. More effective and tolerable maintenance strategies are therefore needed.

Metronomic chemotherapy uses relatively low doses of cytotoxic treatment administered repeatedly over time. In addition to direct antitumor activity, metronomic paclitaxel may modulate the tumor immune microenvironment and enhance the effects of immune checkpoint inhibition. An oral paclitaxel formulation may also be more suitable for long-term maintenance treatment than intravenous paclitaxel because it avoids repeated intravenous infusions.

This is a prospective, open-label, multicenter, nonrandomized, multi-cohort exploratory study. Participants must have completed four cycles of standard first-line chemoimmunotherapy and achieved complete response, partial response, or stable disease without disease progression.

Cohort A will enroll approximately 67 participants with advanced squamous non-small cell lung cancer(sqNSCLC). Cohort B will enroll approximately 40 participants with extensive-stage small cell lung cancer(ES-SCLC). Both cohorts will receive oral paclitaxel solution at 100 mg/m² per dose, administered orally three times weekly, together with a PD-1 or PD-L1 inhibitor administered every 3 weeks according to the approved or guideline-recommended regimen. The maintenance immune checkpoint inhibitor should generally remain the same as that used during induction therapy.

Treatment will continue until radiographic disease progression, unacceptable toxicity, withdrawal of consent, or another protocol-defined discontinuation criterion. Tumor assessments will generally be performed every 6 weeks, and safety assessments will generally be performed every 3 weeks.

The primary endpoint is progression-free survival measured from the first dose of oral paclitaxel. The two cohorts will be analyzed independently, and no formal efficacy comparison between the two cohorts is planned. Exploratory analyses will evaluate circulating tumor DNA, peripheral immune-cell subsets, inflammatory and immune-related factors, and PD-1/PD-L1-related biomarkers.

Change From Baseline in Patient-Reported Lung Cancer Symptoms as Assessed by European Organization for the Research and Treatment of Cancer (EORTC) Quality-of-Life Questionnaire-Core 30 (QLQ-C30) Symptom Score
時間枠:Baseline, Week 6, Week 12, Week 24, every 12 weeks thereafter, and at the end-of-treatment visit, assessed up to 36 months
EORTC QLQ-C30 is a validated and reliable self-report measure that consists of 30 questions that assess five aspects of patient functioning (physical, emotional, role, cognitive, and social), three symptom scales (fatigue, nausea and vomiting, pain), global health/quality of life, and six single items (dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties). EORTC QLQ-C30 is scored according to the EORTC scoring manual (Fayers et al. 2001). All EORTC scales and single-item measures are linearly transformed so that each score has a range of 0-100. A high score for a functional/global health status scale represents a high or healthy level of functioning/HRQoL (Health-Related Quality of Life); however a high score for a symptom scale or item represents a high level of symptomatology or problems. A ≥10-point change in the symptoms subscale score is perceived by patients as clinically significant (Osoba et al. 1998).

The EORTC QLQ-LC13 module incorporates one multiple item scale to assess dyspnea and a series of single items assessing pain, coughing, sore mouth, dysphagia, peripheral neuropathy, alopecia, and hemoptysis.

Percent Change From Baseline in Plasma Circulating Tumor DNA (ctDNA) Maximum Variant Allele Frequency (VAF) at Week 12
時間枠:Baseline and Week 12 (±14 days) after initiation of maintenance treatment

Plasma ctDNA will be assessed using paired blood samples collected at baseline and at Week 12 after initiation of maintenance treatment using the same prespecified next-generation sequencing panel.

Among participants with at least one tumor-associated variant detectable at baseline, the maximum VAF among the baseline-tracked variants will be reported as a percentage at both time points.

Percent change from baseline will be calculated as: [(Week 12 maximum VAF - baseline maximum variant allele frequency) / baseline maximum VAF] × 100. Negative values indicate a reduction in molecular tumor burden, whereas positive values indicate an increase.

Baseline and Week 12 (±14 days) after initiation of maintenance treatment
Change From Baseline in Tumor Programmed Death-Ligand 1 (PD-L1) Tumor Proportion Score (TPS) at Week 12
時間枠:Baseline and Week 12 (±14 days) after initiation of maintenance treatment

Tumor PD-L1 expression will be assessed in paired tumor tissue samples collected at baseline and at Week 12 after initiation of maintenance treatment using the same validated immunohistochemistry (IHC) assay.

PD-L1 expression will be reported as the tumor proportion score, defined as the percentage of viable tumor cells showing partial or complete membranous staining. The TPS ranges from 0% to 100%. Change from baseline will be calculated in percentage points as the Week 12 tumor proportion score minus the baseline tumor proportion score. Positive values indicate increased PD-L1 expression.

This exploratory assessment will be performed in participants with evaluable paired tumor tissue samples. Post-treatment PD-L1 testing is optional for participants in Cohort B.This assessment will be performed only in participants with evaluable paired tumor tissue samples.

Baseline and Week 12 (±14 days) after initiation of maintenance treatment
Change From Baseline in Neutrophil-to-Lymphocyte Ratio (NLR) at Week 12
時間枠:Baseline and Week 12 (±14 days) after initiation of maintenance treatment

The NLR will be calculated by dividing the absolute neutrophil count by the absolute lymphocyte count obtained from the same complete blood count assessment. The NLR is unitless.

Change from baseline will be calculated as the Week 12 NLR minus the baseline NLR ratio. Positive values indicate an increase in the NLR.
