Combining Irinotecan Liposome with S-1 for advanced Nasopharyngeal Carcinoma

The Efficacy and Safety of Irinotecan Liposome Combined with S-1 in PD-1/L1 Inhibitor Refractory Recurrent or Metastatic Nasopharyngeal Carcinoma: a Prospective, Single-arm Phase 2 Study

This study is testing whether a new combination of two medications can help people with advanced nasopharyngeal cancer who haven't responded to previous treatments.

What this trial studies

This Phase 2 clinical trial evaluates the safety and efficacy of Irinotecan Liposome injection combined with S-1 in patients suffering from recurrent or metastatic nasopharyngeal carcinoma (NPC) who have not responded to at least one prior anti-PD-1/L1 treatment. The study will enroll 56 eligible patients who will receive the treatment for up to six cycles, with ongoing assessments of their condition through regular visits and imaging. The trial aims to determine the effectiveness of this combination therapy in managing NPC that is no longer amenable to curative treatment.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with recurrent or metastatic nasopharyngeal carcinoma that has failed at least one line of anti-PD-1/L1 therapy.

Not a fit: Patients with nasopharyngeal carcinoma that has not yet undergone anti-PD-1/L1 treatment or those with curable disease may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with advanced NPC who have limited treatment choices.

How similar studies have performed: While this approach is novel in the context of NPC, similar combination therapies have shown promise in other cancers, indicating potential for success.

Inclusion Criteria:

* 1\. Willing to participate in the study, sign the informed consent form (ICF), and comply with study plan visits, treatment plans, laboratory tests, and other study procedures.

  2\. Age ≥ 18 years. 3. Nasopharyngeal carcinoma confirmed by histopathology (differentiated or undifferentiated non-keratinous carcinoma).

  4\. Recurrent or metastatic nasopharyngeal carcinoma that has failed at least first-line anti-PD-1/L1, whether or not combined with platinum-containing standard regimen (Anti PD-1/L1 exposure at least 6 weeks, and the protocol used at the time of enrollment in this study meets one of the following two points: (1) Relapse during adjuvant therapy after radiotherapy, or relapse within 6 months after the end of treatment; (2) First-line treatment phase, progression during anti-PD-1/L1 treatment, or progression within 3 months after the end of anti-PD-1/L1).

  5\. Recurrent or metastatic nasopharyngeal carcinoma that is unable to local curative treatment (surgery or radiotherapy).

  6\. At least one measurable lesion according to RECIST 1.1 criteria (the spiral CT scan diameter of the measurable lesion is ≥ 10 mm or the short diameter of the enlarged lymph node is ≥15mm ); lesions that have undergone local treatment can be selected as target lesions if there is clear evidence of significant progress compared to the end of treatment.

  7\. ECOG PS (Eastern Cooperative Oncology Group Performance Status) score 0-1. Expected survival ≥3 months.

  8\. Adequate main organ function: a. Liver function: AST and ALT ≤ 2.5 times ULN, bilirubin ≤ 1.5 times the upper limit of normal (ULN) (patients with known Gilbert disease and serum bilirubin level ≤ 3 times ULN could be enrolled; patients with liver metastasis, ≤ 5 times ULN); b. Renal function: serum creatinine ≤ 1.5 ULN or creatinine clearance ≥ 30 mL/min according to Cockcroft-Gault formula; c. Hematology: neutrophil absolute value (ANC) ≥1.0×10\^9/L, hemoglobin (Hb) ≥ 9.0 g/dL, platelets ≥ 100×10\^9/L.

Exclusion Criteria:

* 1\. Severe allergy to Irinotecan liposome (such as systemic rash/erythema hypotension, bronchospasm, angioedema, or anaphylaxis).

  2.CYP3A4 strong inducer used within 2 weeks, or CYP3A4/UGT1A1 strong suppressor used within 1 week prior to initial administration.

  3\. Estimated survival \< 3 months. 4.HBsAg positive and HBV DNA copy number positive (quantitative detection ≥2000 IU/ml); Chronic hepatitis C blood screening positive (HCV antibody positive). Patients with normal liver function and concurrent antiviral therapy were determined by the investigator to be eligible for enrollment.

  5\. HIV-positive people. 6. Patients with active bacterial infection, fungal infection, viral infection, or interstitial pneumonia require systemic treatment within 1 week prior to first administration.

  7\. Received chemotherapy, targeted therapy, immunotherapy, or any investigational drug or other antitumor therapy within 4 weeks or 5 half-lives before first administration (whichever is shorter but at least 2 weeks).

  8\. Received Chinese medicine with antitumor activity within 14 days before administration; Received other investigational drugs within 4 weeks prior to initial dosing.

  9\. Patients who had undergone major surgery within 3 months prior to initial dosing or planned to undergo major surgery during the study period.

  10\. Severe embolic events, such as cerebrovascular accidents (including transient ischemic attacks) and pulmonary embolism, occurred in the 6 months before screening.

  11\. Diagnosed and/or treated with other malignancies within 2 years before initial administration (except for curable malignancies that have undergone radical treatment, such as skin basal cell, carcinoma in situ of the cervix, papillary thyroid cancer, etc).

  12\. Severe cardiovascular disease during the 6 months before enrollment, including but not limited to the following: Acute myocardial infarction, unstable angina pectoris, coronary angioplasty or stenting, deep vein thrombosis, stroke; New York Heart Association Class III or IV congestive heart failure or left ventricular ejection fraction (LVEF) \< 50%; According to the investigator's assessment, clinically significant abnormal electrocardiogram (ECG) at the time of screening.

Serious dysfunction of heart, lung, liver, kidney, and other vital organs; serious and/or uncontrollable disease that may affect the patient's participation in the study (including, but not limited to, uncontrolled diabetes, life-threatening autoimmune and bleeding disorders, substance abuse, neurological disorders, etc.).

  15\. Other situations that the investigator determines to be inappropriate for participation.
