Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The main questions it aims to answer are:
1. How long can this treatment delay the worsening of the cancer (Progression-Free Survival, PFS)?
2. What side effects or medical problems do participants have when taking this combination? This is a single-arm study, meaning all participants will receive the same investigational combination therapy. Researchers will monitor how well the cancer responds and compare the results to historical data from similar patients who received other treatments.
Participants will:
1. Receive treatment in 21-day cycles: take Anlotinib pills on days 1-14 of each cycle and receive platinum-based chemotherapy by intravenous infusion on day 1 (or days 1 and 8).
2. Undergo regular clinic visits for imaging scans (like CT scans), blood tests, and physical examinations to check the cancer's status and their overall health.
3. Complete questionnaires about their quality of life.
4. Provide tumor tissue and blood samples for exploratory research to understand which patients might benefit most from this treatment.
Treatment will continue until the cancer worsens, side effects become intolerable, the participant decides to withdraw, or the study ends.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Therapeutic options for SMARCA4-deficient NSCLC remain an area of active investigation. While platinum-doublet chemotherapy forms the backbone of treatment, the added benefit of ICIs is ambiguous. Large retrospective analyses suggest that tumors harboring SMARCA4 alterations may derive less benefit from frontline chemoimmunotherapy compared to wild-type tumors, highlighting the intrinsic resistance mechanisms and unique tumor microenvironment of this subtype. Therefore, exploring novel combination strategies beyond conventional immunotherapy is critical.
Anlotinib is an orally administered, multi-targeted tyrosine kinase inhibitor that potently inhibits key angiogenesis pathways (VEGFR, PDGFR, FGFR) as well as tumor proliferation pathways (c-Kit, RET). It is approved in China for later-line treatment of advanced NSCLC. Beyond its anti-angiogenic effects, preclinical and clinical evidence suggests that Anlotinib may modulate the tumor immune microenvironment and synergize with chemotherapy to enhance anti-tumor activity. The rationale for combining Anlotinib with platinum-based chemotherapy in SMARCA4-deficient NSCLC is multi-faceted: 1) to provide a robust cytotoxic backbone; 2) to simultaneously inhibit tumor angiogenesis, a potential driver of aggressiveness; and 3) to potentially re-sensitize or circumvent the relative immunotherapy resistance observed in this subtype.
To date, no prospective clinical trial data exist on the use of Anlotinib combined with platinum-based chemotherapy as a first-line treatment for SMARCA4-deficient NSCLC. This phase II, single-arm, open-label study is designed to prospectively evaluate the efficacy and safety of this novel combination regimen in patients with locally advanced or metastatic SMARCA4-deficient NSCLC, confirmed by immunohistochemical loss of BRG1 protein.
The primary objective is to assess progression-free survival (PFS). Secondary objectives include objective response rate (ORR), disease control rate (DCR), duration of response (DoR), overall survival (OS), safety profile, and health-related quality of life (HRQoL). Exploratory biomarker analyses on tumor tissue and blood samples will investigate molecular features of the tumor and its microenvironment to identify potential predictors of response and resistance.
This study aims to generate the first prospective evidence for a targeted-chemotherapy combination in this challenging disease, potentially offering a new and effective first-line treatment strategy for patients with SMARCA4-deficient NSCLC.

combined treatment group
This study evaluates a first-line treatment for locally advanced or metastatic SMARCA4-deficient lung cancer, combining Anlotinib-an oral multi-target tyrosine kinase inhibitor that primarily inhibits tumor angiogenesis-with platinum-based chemotherapy. The rationale for this combination is to integrate potent anti-angiogenic therapy with standard cytotoxic chemotherapy, aiming to address the limited efficacy of current standard therapies in this aggressive molecular subset.
Patients receive the combination of Anlotinib and platinum-doublet chemotherapy for 4-6 induction cycles, followed by Anlotinib monotherapy as maintenance treatment until disease progression or unacceptable toxicity. This design aims to maximize disease control while balancing long-term treatment tolerability.
No prior prospective clinical studies have specifically evaluated this regimen in patients with SMARCA4-deficient NSCLC confirmed by BRG1 protein loss.
Anlotinib, nab-paclitaxel, carboplatin
Participants will receive Anlotinib (12 mg, orally, once daily on days 1-14) in combination with nab-paclitaxel (260 mg/m², IV, administered as a single dose on day 1 or split between days 1 and 8) and carboplatin (AUC=4-5, IV, day 1) every 21 days for 4-6 induction cycles. Dose adjustments may be made based on clinical judgment and tolerability.
Patients who do not experience disease progression or intolerable toxicity following the induction phase will proceed to maintenance therapy with Anlotinib monotherapy (12 mg, orally, once daily on days 1-14 every 21 days).
Treatment will continue until disease progression, unacceptable toxicity, consent withdrawal, investigator decision, loss to follow-up, death, or meeting other protocol-defined criteria for discontinuation.
The maximum duration of Anlotinib treatment is 24 months. Beyond this period, continuation will be at the investigator's discretion based on an individual benefit-risk assessment.
