Clinical Study of Mitoxantrone Hydrochloride Liposome Combined with PD-1 Blockade in Recurrent or Metastatic NPC

A Prospective, Single-arm Phase 2 Study Evaluating the Efficacy and Safety of Mitoxantrone Hydrochloride Liposome Injection Combined with PD-1 Blockade in Previously Treated Recurrent or Metastatic Nasopharyngeal Carcinoma

This is a prospective, single-arm Phase 2 study to evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection combined with PD-1 blockade in patients with recurrent (not unable to locally curative treatment) or metastatic NPC who failed at least first-line platinum-containing standard regimen and/or anti PD-1/L1.

Study Overview

• Status: Recruiting
• Conditions: Recurrent or Metastatic Nasopharyngeal Carcinoma
• Intervention / Treatment: Drug: Mitoxantrone hydrochloride liposome injection; Drug: PD-1 Inhibitors

Detailed Description

Thirty-two recurrent (not unable to locally curative treatment) or metastatic NPC patients who had failed at least first-line platinum-containing standard regimen and/or anti PD-1/L1 were eligible to receive mitoxantrone hydrochloride liposome injection combined with PD-1 blockade once every 3 weeks for up to 8 cycles, following PD-1 blockade alone once every 3 weeks for 2 years. All patients will be treated until disease progression as determined by the investigator based on RECIST 1.1 criteria, intolerable toxicity, subject withdrawal of informed consent, initiation of new antitumor therapy, loss of follow-up, death, or study completion, whichever occurs first. Regular visits and imaging examinations will be conducted to evaluate the efficacy and safety of the treatment regimen.

3. Age ≥ 18 & ≤ 70 years.
4. PS (Performance Status) score 0-1.
5. Recurrent or metastatic nasopharyngeal carcinoma that has failed first-line platinum-containing standard regimen and/or second-line standard regimen failure.
6. Previously received at least one line of systemic therapy. (Progression after radical concurrent chemoradiotherapy, during neoadjuvant or adjuvant therapy, or within 6 months after the end of treatment can be recorded as 1-line therapy).
7. Recurrent or metastatic nasopharyngeal carcinoma that has failed anti PD-1/L1: 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 (whether combined with chemotherapy/targeting drugs);
8. 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.
9. All acute toxicities of previous antitumor therapy have returned to ≤ grade 1 (according to NCI-CTCAE v5.0) or reached the level specified in the inclusion/exclusion criteria. (Except for partial toxicity, such as alopecia, hair color change, nail change, fatigue, etc., which do not pose safety risks to subjects).
10. Adequate main organ function. a. Hematology: neutrophil absolute value (ANC) ≥1.5×10^9/L, hemoglobin (Hb) ≥ 9.0 g/dL, platelets ≥ 100×10^9/L; b. Liver function: 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), AST and ALT ≤ 3 times ULN, and alkaline phosphatase ≤ 3 times ULN; Albumin ≥ 3 g/dL; c.

Note: The UPC ratio of random urine is a quantitative estimate of 24-hour urinary protein, and the two have a good correlation. UPC ratio can be calculated using the following formula: (a) Urinary protein/urinary creatinine (if both protein and creatinine are mg/dL); (b) (urinary protein)*0.088/ urinary creatinine (if urinary creatinine is mmol/L).
