NKTR-102 in Combination With Cetuximab in Patients With Refractory Solid Tumors (Phase 2a) and Metastatic or Locally Advanced Colorectal Cancer (Phase 2b)
Condition: Tumor; Colorectal Cancer
MeSH terms: Colorectal Neoplasms
Intervention: NKTR-102 100 mg/m2; NKTR-102 125 mg/m2; Cetuximab
Intervention description: NKTR-102 100 mg/m2 + Cetuximab Arm:
All patients received NKTR-102 in combination with cetuximab. NKTR-102 was administered intravenously (IV) once every 3 weeks (q3w) over 90 minutes on Day 1. Patients were to be enrolled in one of the following sequential dosing cohorts of NKTR-102: 100, 125, 150, or 175 mg/m2. Only the 100 and 125 mg/m2 were enrolled.; NKTR-102 125 mg/m2 + Cetuximab Arm:
All patients received NKTR-102 in combination with cetuximab. NKTR-102 was administered intravenously (IV) once every 3 weeks (q3w) over 90 minutes on Day 1. Patients were to be enrolled in one of the following sequential dosing cohorts of NKTR-102: 100, 125, 150, or 175 mg/m2. Only the 100 and 125 mg/m2 were enrolled.; Cetuximab was administered once weekly via a 2-hour IV infusion at a starting dose of 400 mg/m2 on Day 1 and subsequently administered weekly at 250 mg/m2 via a 1-hour infusion thereafter.

Summary:

      Study 07-PIR-02 is a Phase 2 study designed to evaluate the safety and efficacy of NKTR-102
      (PEG-irinotecan) for the treatment of patients with colorectal cancer (CRC). The study is
      comprised of two sequential components - Phase 2a and Phase 2b. The Phase 2a portion is an
      open-label, dose-finding trial in multiple solid tumor types that are refractory to standard
      curative or palliative therapies. The primary endpoint of the Phase 2a is to establish the
      /recommended Phase 2 Dose (RPTD) of NKTR-102 by measuring the frequency of Dose Limiting
      Toxicity (DLT). The Phase 2b portion is an open-label, randomized, two-arm study in patients
      with second-line metastatic colorectal cancer and study participants will be randomized (1:1)
      to receive either NKTR-102 and cetuximab or irinotecan and cetuximab. The primary endpoint of
      the Phase 2b portion of the trial is progression-free survival. Secondary endpoints for both
      the Phase 2a and 2b portion include response rate, response duration, overall survival,
      standard pharmacokinetics, and incidence of toxicities, including diarrhea and neutropenia.
