Patritumab With Cetuximab and a Platinum Containing Therapy for Patients With Head and Neck Cancer

An Open Label, Phase 1B Safety Evaluation of Patritumab (U31287) in Combination With Cetuximab Plus Platinum Containing Therapy In Subjects With Recurrent or Metastatic Squamous Cell Carcinoma of the Head and Neck

The purpose of this study is to test a study drug called patritumab. Patritumab may work when combined with other medications that are approved in the UK for treating Squamous Cell Carcinoma of the Head and Neck (SCCHN), called cetuximab, cisplatin or carboplatin. It is hoped that patritumab may have some benefit in treating patients with cancer. This study will help identify how much patritumab can be given in combination with cetuximab, and cisplatin or carboplatin. This study will show how safe and how well tolerated patritumab is when these medications are given together.

Study Overview

• Status: Completed
• Conditions: Squamous Cell Carcinoma of the Head and Neck

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: All Participants - Period 1; All participants receive patritumab with cetuximab plus platinum-based therapy (cisplatin or carboplatin) in Period 1 - Initial phase of the trial.	Drug: Patritumab; Patritumab initial loading dose is 18 mg/kg IV over 60 minutes, followed in Cycle 2 and beyond with a maintenance dose of 9 mg/kg IV over 60 minutes (+/- 10 minutes) every 3 weeks. Infusion time can be extended to a maximum of 120 minutes for participants unable to tolerate the 60-minute infusion.; Other Names: Monoclonal antibody; U3-1287; Drug: Cetuximab; Cetuximab initial dose at 400 mg/m2 IV as a 2-hour infusion, followed by 250 mg/m2 IV over 60 minutes weekly.; Other Names: Chemotherapy; Drug: Cisplatin; Cisplatin is given as an IV infusion, over 1 hour, 1 hour after the cetuximab infusion, every 3 weeks up to a maximum of 6 cycles (with standard pre- or post-treatment therapies at the investigator's discretion).; Other Names: Chemotherapy; Platinum therapy; Drug: Carboplatin; Carboplatin is given as an IV-bolus, over 30-60 minutes, every 3 weeks, for a maximum of 6 cycles (with standard pre- or post-treatment therapies at the investigator's discretion).; Other Names: Chemotherapy; Platinum therapy
EXPERIMENTAL: All Participants - Period 2; Participants deriving clinical benefit enter Period 2 - Extension phase, during which they continue to receive patritumab with cetuximab, but not platinum-based therapy.	Drug: Patritumab; Patritumab initial loading dose is 18 mg/kg IV over 60 minutes, followed in Cycle 2 and beyond with a maintenance dose of 9 mg/kg IV over 60 minutes (+/- 10 minutes) every 3 weeks. Infusion time can be extended to a maximum of 120 minutes for participants unable to tolerate the 60-minute infusion.; Other Names: Monoclonal antibody; U3-1287; Drug: Cetuximab; Cetuximab initial dose at 400 mg/m2 IV as a 2-hour infusion, followed by 250 mg/m2 IV over 60 minutes weekly.; Other Names: Chemotherapy

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of participants experiencing dose-limiting toxicities (DLTs)	DLTs are used to determine the maximum tolerated dose.	6 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pharmacokinetic profile of serum patritumab	Cmax and AUC	6 months
Pharmacokinetic profile of serum cetuximab	Cmax and AUC	6 months
Percentage of participants with human anti-human antibody (HAHA) formation (anti-patritumab antibodies)		6 months
Titer of HAHA formation (anti-patritumab antibodies)	A titer is a way of expressing concentration. Titer testing employs serial dilution to obtain approximate quantitative information from an analytical procedure that inherently only evaluates as positive or negative. The titer corresponds to the highest dilution factor that still yields a positive reading.	6 months
