Lomustine Combined With Anlotinib as Interventional Therapy for Extensive-stage Small Cell Lung Cancer Resistant to Second-line and Above Treatment

Официальное название

A Single-arm, Phase II Interventional Study to Evaluate the Efficacy and Safety of Lomustine Combined With Anlotinib in Patients With Extensive-stage Small Cell Lung Cancer Resistant to Second-line and Further Lines of Treatment

Обзор

This single-arm phase II study aims to evaluate the efficacy and safety of lomustine combined with anlotinib in patients with extensive-stage small cell lung cancer resistant to second-line and above systemic treatment.

Подробное описание

This is a single-arm phase II clinical study evaluating the efficacy and safety of lomustine combined with anlotinib in extensive-stage small cell lung cancer resistant to second-line and subsequent treatments. A total of 46 patients with extensive-stage small cell lung cancer who have received at least two lines of prior systemic therapy will be enrolled and treated with lomustine plus anlotinib. The primary endpoint is investigator-assessed objective response rate (ORR). Secondary endpoints include investigator-assessed progression-free survival (PFS), investigator-assessed disease control rate (DCR), intracranial response rate assessed per RANO criteria (RANO-IRR), investigator-assessed overall survival (OS), adverse events, quality of life (QOL) scores and safety profiles.

Вмешательства

• Препарат Lomustine
  Oral lomustine 60 mg/m² once daily on day 1, every 6 weeks
• Препарат Anlotinib
  Oral administration, initial dose 12 mg, 10 mg or 8 mg once daily on days 1-14 of every 3-week cycle

Первичные конечные точки

• Objective Response Rate [Срок оценки: Baseline at screening, after every 2 treatment cycles (each cycle is 21 days), end of treatment, up to disease progression, assessed up to approximately 24 months]

Вторичные конечные точки (4)

• progression free survival [Срок оценки: Date of first study treatment to date of disease progression or death from any cause, last follow-up, assessed up to approximately 24 months]
• Disease Control Rate (DCR) [Срок оценки: Time Frame: Baseline and after every 2 treatment cycles (each cycle is 21 days), up to disease progression, death, or study withdrawal, whichever occurs first，assessed up to approximately 24 months]
• Adverse Event (AE) [Срок оценки: From signing informed consent through study completion and safety follow-up, assessed up to approximately 24 months]
• Quality of Life Score（QOL Score） [Срок оценки: At baseline, every 6 weeks during treatment until disease progression or death，assessed up to approximately 24 months]

Критерии участия

Критерии включения

Критерии исключения

• 1: Previous treatment with lomustine, anlotinib, or other similar anti-angiogenic TKIs.

2: Uncontrolled central nervous system (CNS) metastases (e.g., unstable or symptomatic brain metastases, or those requiring ongoing glucocorticoid therapy).

3: Active bleeding or high bleeding risk (e.g., history of massive gastrointestinal hemorrhage or cerebral hemorrhage within the past 6 months, or presence of unhealed wounds or ulcers).

4: Uncontrolled hypertension (systolic blood pressure ≥ 160 mmHg or diastolic blood pressure ≥ 100 mmHg) or severe cardiovascular diseases (e.g., myocardial infarction, severe arrhythmia, heart failure within the past 6 months).

5: Active infection (such as pneumonia, sepsis) or uncontrolled systemic diseases (such as uncontrolled diabetes, autoimmune diseases).

6: Pregnant or lactating females. Female participants must use effective contraception during treatment and for 6 months after the last dose of study treatment; male participants must use effective contraception during treatment and for 3 months after the last dose of study treatment.

7: History of other malignant tumors within the past 5 years, except for cured basal cell carcinoma of the skin, carcinoma in situ of the cervix, and other cured malignancies.

8: Known hypersensitivity to lomustine, anlotinib, or any excipient in their formulations.

9: Any other condition deemed inappropriate for participation in this study by the investigator (e.g., mental disorders, inability to comply with follow-up procedures).
