About this study

Official title: A Multicenter, Open-Label, Phase 2 Study to Determine the Dose, Safety and Efficacy of NKTR-102 (PEG-Irinotecan) in Combination With Cetuximab in Patients With Solid Tumors Refractory to Standard Treatment and to Evaluate the Safety and Efficacy of NKTR-102 or Irinotecan in Combination With Cetuximab in Second Line, Irinotecan and Cetuximab Naïve, Colorectal Cancer Patients With Metastatic or Locally Advanced Disease

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.

Read the detailed description

The Phase 2a portion of this study is completed. The following entries reflect the Phase 2a portion of this study only. The Phase 2b portion of the study was not enrolled. Based on emerging data regarding the corresponding low efficacy of cetuximab in patients with KRAS mutations, as well as revised NKTR-102 clinical development plans, the Phase 2b portion of the study was not completed.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • NKTR-102 100 mg/m2Drug

    Also called PEG-Irinotecan

    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/m2Drug

    Also called PEG-Irinotecan

    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.

  • CetuximabDrug

    Also called Erbitux

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Patients With Dose Limiting Toxicities

    Number of patients with Dose Limiting Toxicities

    Measured: 12 months

Secondary outcomes (2)
  1. Number of Patients With Dose Limiting Toxicities by NCI-CTCAE

    Number of patients with Dose Limiting Toxicities by NCI-CTCAE

    Measured: 12 months

  2. Number of Patients With Overall Response

    Complete Response is defined as the disappearance of all target lesions. Partial Response is defined as at least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the baseline sum longest diameter. The best overall response was the best response recorded from the start of the study drug until disease progression/recurrence (taking as reference for progressive disease the smallest measurements recorded since the treatment started).

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing NKTR-102 100 mg/m2, NKTR-102 125 mg/m2 and Cetuximab in people with Tumor and Colorectal Cancer, run by Nektar Therapeutics at 4 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 14 Jun 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Patients With Dose Limiting Toxicities (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Jul 2021.
