Efficacy and Safety of Paclitaxel Polymeric Micelles in Patients With Recurrent/Metastatic Head and Neck Squamous Cell Carcinoma

Efficacy and Safety of Paclitaxel Polymeric Micelles in Patients With Recurrent/Metastatic Head and Neck Squamous Cell Carcinoma: An Open-Label, Single-Arm, Exploratory Phase II Clinical Study

Paclitaxel polymeric micelles 300 mg/m², IV infusion over ≥3 hours, Day 1; carboplatin AUC 5, IV infusion over 1 hour, Day 1. Each cycle consists of 3 weeks (Q3W), for a total of 3 cycles. (Efficacy assessment will be performed after 3 cycles of treatment. In the absence of disease progression, treatment may be continued until disease progression (PD), intolerable toxicity, withdrawal of informed consent, initiation of other antineoplastic therapy, death, or other protocol-specified criteria for treatment discontinuation, whichever occurs first.)

Description

Inclusion Criteria:

• Age ≥18 and ≤75 years, male or female; Histologically or cytologically confirmed head and neck squamous cell carcinoma; Prior first-line systemic therapy (including chemotherapy, targeted therapy, and immunotherapy) with disease progression or judged by the clinician to no longer derive clinical benefit; ECOG performance status score of 0-2 and a life expectancy of at least 3 months; At least one measurable lesion on imaging according to the Response Evaluation Criteria in Solid Tumors (RECIST v1.1, Appendix 3);

Adequate major organ function, with subjects meeting the following laboratory parameters:

Complete blood count meeting the following criteria (no blood transfusion, blood products, granulocyte colony-stimulating factor, or other hematopoietic growth factors within 7 days prior to the test): WBC ≥3.0×10^9/L, ANC ≥1.5×10^9/L, platelets ≥100×10^9/L, hemoglobin ≥90 g/L; Blood biochemistry meeting the following criteria: total bilirubin ≤1.5×ULN, AST, ALT, or ALP ≤2.5×ULN (for subjects with liver metastases, ALT, AST, or ALP ≤5×ULN is permitted; for subjects with bone metastases, ALP ≤10×ULN is permitted); serum creatinine ≤1.5×ULN and creatinine clearance (calculated using the Cockcroft-Gault formula, Appendix 4) ≥50 mL/min; Adequate coagulation function, defined as INR ≤1.5×ULN and PT or APTT ≤1.5×ULN; Subjects of childbearing potential must agree to use highly effective contraceptive measures during the trial. Women of childbearing potential must have a negative serum or urine pregnancy test within 72 hours prior to the start of chemotherapy; Good compliance, able to undergo treatment and follow-up, and willing to comply with the study requirements; voluntary signing of the informed consent form.

Exclusion Criteria:

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
objective response rate	ORR was defined as the percentage of participants in the analysis population who have a Complete Response (CR: disappearance of all target lesions) or a Partial Response (PR: ≥30% decrease in the sum of diameters of target lesions) per RECIST 1.1.	12 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Progression Free Survival Per RECIST 1.1	PFS was defined as the time from enrollment to the first documented PD per RECIST 1.1, or death due to any cause, whichever occurred first. Per RECIST 1.1, PD was defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum had to demonstrate an absolute increase of ≥5 mm. The appearance of one or more new lesions was also considered PD	12 months
overall survival	OS was defined as the time from enrollment to death due to any cause. Participants without documented death at the time of the final analysis were censored at the date of the last follow-up.	12 months
Number of Participants Experiencing an Adverse Event (AE)	An AE was defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which did not necessarily have to have a causal relationship with this treatment. An AE could therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening of a pre-existing condition that was temporally associated with the use of the Sponsor's product was also an AE. The number of participants that experienced at least one AE was reported for each treatment arm.	12 months
