Eligibility Criteria
Inclusion
- Patients aged 18 to 75 years, inclusive, regardless of gender.
- Histologically or cytologically confirmed small-cell carcinoma of the lung or cervix that is not curable by surgery or radiochemotherapy.
- Have received at least two prior systemic treatment regimens, including etoposide and platinum-based chemotherapy, and have experienced disease progression.
- No receipt of investigational or approved cytotoxic chemotherapy within 28 days before enrollment; no receipt of alkylating agents within 42 days before enrollment; no receipt of investigational or approved targeted therapy within 28 days or 5 half-lives before enrollment (whichever is shorter, but not less than 14 days); no radiotherapy within 14 days before enrollment.
- Presence of measurable disease according to RECIST 1.1 criteria; measurable lesions are defined as lesions that can be accurately measured in at least one dimension (longest diameter ≥10 mm on CT or MRI scans, and lymph nodes with short-axis diameter ≥15 mm).
- Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
- Expected survival of ≥12 weeks.
- Recovery of prior anticancer treatment toxicities to ≤Grade 1 (except for alopecia, pigmentation, or other toxicities deemed non-safety risks by the investigator); for irreversible toxicities that are not expected to worsen with study drug administration (e.g., hearing loss), inclusion may be considered after consultation with the medical monitor. Recovery of peripheral neuropathy to ≤Grade 2 after prior use of cisplatin or etoposide may be considered for inclusion after consultation with the medical monitor. For late toxicities caused by radiotherapy that cannot be recovered, inclusion may be considered after consultation with the medical monitor.
- Laboratory tests: Absolute neutrophil count ≥1.5×10⁹/L; platelets ≥75×10⁹/L; hemoglobin ≥90 g/L; serum creatinine ≤1.5 times the upper limit of normal (ULN); urine protein \<2+ or 24-hour urine protein \<1.0 g; alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤2.5 times ULN (or ≤5 times ULN in the presence of liver metastasis); total bilirubin ≤1.5 times ULN; albumin ≥28 g/L; coagulation function: prothrombin time (PT) and international normalized ratio (INR) ≤1.5×ULN.
- Female subjects with negative urine or blood HCG (except for menopausal and hysterectomy cases); sexually active female subjects and their partners must agree to use effective contraception (e.g., combined hormonal contraception, intrauterine device, bilateral tubal ligation, vasectomy, abstinence) during the study and for 6 months after the last dose.
- Availability of tumor specimens (paraffin-embedded blocks or frozen tissue) from prior resection or biopsy sufficient for pharmacodynamic assays (≥3 slides for immunohistochemistry IHC) (mandatory for dose-expansion cohort patients only).
- Ability to understand the study and voluntary consent to participate in the trial by the patient or their legal representative, with signed informed consent.
Exclusion
- Histological diagnosis of squamous cell carcinoma, adenocarcinoma, or other non-small-cell types of lung or cervical cancer.
- Concurrent enrollment in another clinical trial, unless it is an observational, non-interventional study or the follow-up period of an interventional study.
- Known hypersensitivity to any component of penfluridol or similar compounds with comparable chemical or biological properties.
- Prior exposure to penfluridol.
- Known presence of leptomeningeal metastasis, spinal cord compression, leptomeningeal disease, or active brain metastases. However, patients with asymptomatic brain metastases (no neurological deficits, seizures, or other typical symptoms and signs of central nervous system metastasis; no requirement for corticosteroids) or those who have been treated and are stable on imaging for at least 4 weeks before study treatment (with no new or enlarged brain metastases) and have discontinued systemic corticosteroids and anticonvulsant medications for at least 2 weeks may be included.
- Uncontrolled comorbid conditions, including but not limited to persistent or active infections or psychiatric/social conditions that would limit compliance with study requirements.
- Positive for human immunodeficiency virus (HIV) on combination antiretroviral therapy.
- Cardiovascular history or comorbidities: Known history of arrhythmias (including atrial fibrillation, tachycardia, or bradycardia), except for benign ventricular premature beats; history of CHF, MI, or stroke within the past 3 months.
- History of seizure within the past 3 months.
- Gastrointestinal dysfunction or disease that may significantly alter the absorption of penfluridol (e.g., uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, or small bowel resection).
- Known history of allogeneic organ transplant or allogeneic hematopoietic stem cell transplant.
- Uncontrolled severe medical conditions that, in the opinion of the investigator, would affect the patient's ability to receive the study treatment, such as severe internal medicine conditions, including hepatic or renal insufficiency, severe cardiovascular disease, cerebrovascular disease, uncontrolled diabetes, or uncontrolled infections.
- Pregnant or breastfeeding women; sexually active female subjects unwilling to use contraception.
- Presence of symptomatic or unstable pleural effusion, ascites, or pericardial effusion requiring repeated drainage.
- Patients deemed unsuitable for the study by the investigator.
