February 16, 2025 updated by: NeoTX Therapeutics Ltd.

Phase 2a Open-Label, Multicenter Trial of Naptumomab Estafenatox (NAP) in Combination With Docetaxel Following Obinutuzumab Pretreatment in Subjects With Checkpoint Inhibitor Pretreated Advanced or Metastatic Non-Small Cell Lung Cancer

Phase 2a Open-Label, Multicenter Trial of Naptumomab Estafenatox (NAP), following Obinutuzumab Pretreatment, on Days -13 and -12. NAP will be administered on Days 1-4 of treatment cycles 1-6, followed by docetaxel on Day 5. Starting cycle 7, NAP at a higher dose will be administered on Day 1 only and docetaxel on Day 2, in 21 days treatment cycles. When NAP is administered as monotherapy and not earlier than cycle 7, NAP will be administered on Day 1 only and cycles will be of 28 days treatment cycle.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Patients must have received at least 1 and no more than 2 prior systemic regimens for the treatment of advanced/metastatic NSCLC. Patients were required to have progressed following treatment with both platinum-based chemotherapy and an anti-PD-(L)1 antibody administered either sequentially or concurrently. Entry into this trial was restricted to patients with incurable disease, including those whose disease had relapsed within 6 months after chemoradiotherapy for Stage III disease. Patients were to have available archival or fresh tissue collected for the retrospective determination of tumoral 5T4 levels.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

  6. Subjects must have measurable neoplastic disease based on the iRECIST criteria
  7. Subjects must have received as least 1 and no more than 2 prior systemic regimens for the treatment of advanced/metastatic NSCLC. Patients are required to have progressed following treatment with both platinum-based chemotherapy and an anti-PD-(L)1 antibody administered either sequentially or concurrently. A prior PD-1/PD-L1 inhibitor is, however, not required if there was prior exposure to targeted therapies for a driver mutation positive tumors (e.g. EGFR or ALK inhibitors).

Main Exclusion Criteria:

  1. Subjects with active infection requiring treatment within 3 days of C1D1.
  2. Subjects with other active neoplastic disease requiring concurrent anti-neoplastic treatment
  3. Subjects with known, suspected or documented parenchymal brain metastases unless treated with surgery and/or radiation, with the subject neurologically stable and off pharmacologic doses of systemic glucocorticoids; subjects with leptomeningeal metastases are not eligible. Patients should have completed brain radiation for at least 14 days and be off steroids.

  4. Active or previously documented autoimmune or inflammatory disorders such as, but not limited to rheumatoid arthritis, systemic lupus erythematosus, uveitis, ulcerative colitis, Crohn's syndrome, Wegener's syndrome, multiple sclerosis, myasthenia gravis, scleroderma and sarcoidosis. The following are exceptions to this criterion:

    • Vitiligo or psoriasis not requiring systemic treatment (within the last 2 years)

Experimental: NAP in combination with docetaxel following obinutuzumab pretreatment
Subjects receive obinutuzumab, 1,000 mg, administered by IV infusion on Days -13 and -12 of the first treatment cycle in order to reduce the titer of anti-drug antibodies to NAP. NAP is administered by IV bolus on Days 1 - 4 of treatment cycles 1-6, followed by docetaxel on Day 5. Treatment cycles with the combination NAP/docetaxel are of 21 days in duration. Starting cycle 7, NAP at a higher dose is administered on Day 1 and docetaxel on Day 2, in 21 days treatment cycles. Once NAP is given as monotherapy and not earlier than C7, cycles are of 28 days of duration.
Drug: Obinutuzumab
Obinutuzumab is administered as pre-medication on Day -13 and -12 of the first treatment cycle.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Objective Response Rate (ORR)
Time Frame: From the first treatment to first CR or PR (estimated about 24 months)
Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) and iRECIST for target lesions and assessed by CT scans or MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR
From the first treatment to first CR or PR (estimated about 24 months)

Secondary Outcome Measures

Progression-free Survival (PFS)
Time Frame: From the first administration of treatment to the date of first documentation of disease progression, or death due to any cause, whichever occurs first (estimated about 24 months).
PFS per Response Evaluation in Solid Tumors (iRECIST)
