FID-007 and Cetuximab in Treating Patients With Advanced Head and Neck Squamous Cell Carcinoma

The goal of this FID-007 Randomized, Multicenter, Open-label clinical trial is to compare the efficacy of different dosing regimens of FID-007 in combination with Cetuximab in patients with recurrent or metastatic Head and Neck Squamous Cell Carcinoma (HNSCC) based on objective response rate. The main questions it aims to answer are:

* To evaluate the efficacy of different dosing regimens of FID-007 in combination with Cetuximab in patients based on Best Overall Response (BOR), Duration of Response (DoR), Disease Control Rate (DCR), Progression-Free Survival (PFS), and Overall Survival (OS). * To characterize the pharmacokinetics (PK) of FID-007 and its metabolites (6-α-hydroxypaclitaxel and 3'-p-hydroxypaclitaxel) following administration of different dosing regimens of FID-007 in combination with Cetuximab in patients with recurrent or metastatic HNSCC. * To characterize the safety and tolerability of different dosing regimens of FID-007 in combination with Cetuximab in patients.

Eligible participants will be enrolled and randomized to 1 of 2 arms of FID-007 with fixed-dose Cetuximab (starting from Cycle 2, 500 mg/m2 intravenous \[IV\] infusion every 2 weeks on Days 1 and 15 of each 28-day cycle). Patients will receive FID-007 via IV infusion over 30 minutes at their assigned dose on Days 1, 8, and 15 of each 28-day cycle.

Patients will continue to receive Cetuximab and FID-007 until they meet the study drug discontinuation criteria.
