A Study of ZN-e4 in Subjects With Epidermal Growth Factor Receptor Mutated Non-Small Cell Lung Cancer

January 23, 2024 updated by: Zeno Pharmaceuticals, Inc.

A Phase 1/2 Open Label, Multicenter Study to Assess the Safety, Tolerability, Pharmacokinetics, and Anti-tumor Activity of ZN-e4 (KP-673) in Patients With Advanced Non-Small Cell Lung Cancer With Activating Epidermal Growth Factor Receptor (EGFR) Mutations

This is a Phase 1/2, open-label, multicenter, sequential dose-escalation study to evaluate the safety, tolerability, pharmacokinetics (PK), and preliminary efficacy of ZN-e4 administered orally in subjects with advanced non-small cell lung cancer (NSCLC) with activating EGFR mutations who have progressed while on treatment with an EGFR tyrosine kinase inhibitor (TKI) agent (other lines of treatment are allowed, except for other epidermal growth factor receptor inhibitors [EGFRis]) for Phase 1; and for Phase 2, subjects who have T790M+ and are osimertinib naïve (Cohort 1), and also those who have not been treated with an EGFR Inhibitor (EGFRi) (Cohort2).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

Description

INCLUSION CRITERIA

  • Age ≥ 18 years
  • Histologically or cytologically confirmed metastatic or advanced inoperable diagnosis of NSCLC
  • Documented radiographic progression on the last treatment administered prior to enrolling in the study.
  • Phase 1 only: Confirmation that the tumor harbors an EGFR mutation known to be associated with aberrations that are amenable to EGFRi therapy including but not limited to: G719X, exon 19 deletion, exon 21 L858R, and L861Q. OR - Must have experienced clinical benefit from an EGFRi,
  • All acute toxic effects of any prior antitumor therapy resolved to Grade ≤1 or baseline before the start of study drug dosing (with the exception of alopecia [any grade permitted] and neurotoxicity [Grade 1 or 2 permitted]).
  • Measurable disease meeting the criteria specified by RECIST v1.1
  • Phase 2, Cohort 1 only: Subjects must have confirmation of tumor T790M mutation status (confirmed positive) and are osimertinib naïve
  • Phase 2, Cohort 2 only: EGFR aberrations that are amenable to EGFRi therapy, including but not limited to: G719X, exon 19 deletion, exon 21 L858R, and L861Q, and be EGFRi naïve

EXCLUSION CRITERIA

  • Subjects who have received only neoadjuvant or adjuvant therapy for NSCLC.
  • Phase 1 only: Treatment with an EGFRi within 7 days or 5 half-lives of the first dose of study treatment, whichever is shorter.
  • Phase 1 only: Cytotoxic chemotherapy, investigational agents, or any anticancer therapy for the treatment of advanced NSCLC (other than EGFRi) within 21 days of the first dose of study treatment.
  • Prior treatment with immunotherapy within 3 months prior to the first dose of study treatment.
  • Radiotherapy within 28 days of first dose of study treatment; subjects given palliative radiotherapy to peripheral sites (e.g., bone metastases) may enter the study before 28 days have elapsed provided the radiated sites do not contain lesions which may be used to evaluate response, and must have recovered from any acute, reversible effects.
  • Known or suspected central nervous system (CNS) metastases or leptomeningeal disease (Phase 1 only). Subjects with previously treated brain or CNS metastases are eligible provided that the subject has recovered from any acute effects of radiotherapy, does not have brain metastasis related symptoms, is not requiring systemic steroids for at least 2 weeks prior to study drug administration, and any whole brain radiation therapy was completed at least 4 weeks prior to study drug administration, or any stereotactic radiosurgery (SRS) was completed at least 2 weeks prior to study drug administration.

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.
