Phase 1
Terminated
Conditions
Non-small Cell Lung Cancer
Interventions
Registration Number
NCT02192697
Lead Sponsor
Astellas Pharma Inc
Brief Summary

Purpose of the study is to determine the following in patients with non-small cell lung cancer (NSCLC) harboring EGFR activating mutations.

* the safety and tolerability of ASP8273.

* the pharmacokinetics (PK) of ASP8273.

* the antitumor activity of ASP8273.

Detailed Description

This study consists of Phase I and Phase II.

The objectives of Phase I are to determine the following in patients with non-small cell lung cancer (NSCLC) harboring EGFR activating mutations.

* safety and tolerability of ASP8273.

* the maximum tolerated dose (MTD) and/or recommended phase II dose (RP2D) of ASP8273 based on the dose limiting toxicity (DLT) profile.

* pharmacokinetics (PK) of ASP8273.

* antitumor activity of ASP8273.

The objectives of Phase II are to determine the following at the RP2D of ASP8273 in patients with NSCLC harboring EGFR mutation.

* efficacy of ASP8273

* safety of ASP8273

* PK of ASP8273

Inclusion Criteria
  • Histologically or cytologically confirmed diagnosis of NSCLC.

  • Patients confirmed to have the del ex19, L858R, G719X, or L861Q mutation among the EGFR activating mutations (patients at the study site who are documented to have any of the above-stated EGFR activating mutations can be enrolled in the study).

  • Life expectancy ≥ 12 weeks based on the investigator's/subinvestigator's judgment.

  • [Phase I]

    • Patients who have previously been treated with EGFR tyrosine-kinase inhibitors (EGFR-TKIs)*
    • Those who are not expected to show a therapeutic response to existing treatments in the investigator's/subinvestigator's opinion.
  • [Phase II]

    • Patients who have been confirmed to have progressive disease (PD) after previous treatment with EGFR-TKIs*; for those who have received 2 or more regimens of previous treatment, the last regimen before enrollment should have included EGFR-TKIs.
    • *Erlotinib, gefitinib, and EGFR-TKIs under clinical investigation (e.g., neratinib, afatinib, dacomitinib)
    • Expression of the EGFR-T790M mutation as confirmed by a tumor biopsy of the primary or metastatic lesions after confirmation of PD following previous treatment with EGFR-TKIs and before enrollment, or by a tumor tissue sample that had been collected and archived after confirmation of PD following previous treatment with EGFR-TKIs.
    • At least 1 measurable lesion based on Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1.
Exclusion Criteria
  • Persistent clinical evidence of previous antitumor treatment related toxicity ≥ Grade 2 using the Japan Clinical Oncology Group (JCOG) Japanese translation of the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 (NCI CTCAE v4.0 - JCOG) (except alopecia and skin toxicities considered irrelevant in study enrollment by the investigator/sub-investigator).
  • History of or concurrent interstitial lung disease
  • Received treatment with a reversible EGFR-TKI (erlotinib or gefitinib) within 8 days before the start of the study treatment.
  • Received previous treatment (except reversible EGFR-TKIs) intended to have antitumor effects or treatment with another investigational drug or an investigational device within 14 days before the start of the study treatment.
  • Previously received treatment with EGFR-TKIs (e.g., CO-1686, AZD9291) that can inhibit EGFR with the T790M mutation.
  • It is planned that the subject will undergo a surgical procedure during the course of the study or the subject still has an unhealed wound after previous surgery
  • Symptomatic central nervous system (CNS) lesions.

Primary Outcome Measures
NameTimeMethod
Phase II: Overall response rate (CR+PR) at Week 24Week 24

The overall response rate, which is defined as the proportion of subjects whose best overall response is rated as complete response (CR) or partial response (PR) according to RECIST Version 1.1, will be calculated

Phase I: Safety and tolerability of ASP8273 as assessed by Dose Limiting Toxicities (DLTs)Up to Day 23

A DLT is defined as any pre-determined toxicity that is related to study drug per the investigator and which occurs during Cycle 0 and Cycle 1 using the Japan Clinical Oncology Group (JCOG) Japanese translation of the Common Terminology Criteria for Adverse Events version 4.0 (CTCAE ver 4.0 - JCOG)

Secondary Outcome Measures
NameTimeMethod
Phase I: Safety and tolerability of ASP8273 as assessed by laboratory testsUp to 18 months

Laboratory tests to be conducted are hematology, biochemistry, urinalysis, coagulation profile, lipid panel and lymphocyte subpopulation

Phase I: Disease control rate (CR+PR+SD)Up to 18 months

The disease control rate is defined as the proportion of subjects whose best overall response is rated as CR, PR, or stable disease (SD) according to RECIST Version 1.1, will be calculated.

Phase I: Plasma concentrations of unchanged ASP8273Up to Day 1 of Cycle 3
Phase I: Urine concentrations of unchanged ASP8273Up to Day 1 of Cycle 3
Phase I: Overall response rate (CR+PR)Up to 18 months

The overall response rate is defined as the proportion of subjects whose best overall response is rated as complete response (CR) or partial response (PR) according to RECIST Version 1.1, will be calculated

Phase II: Urine concentrations of unchanged ASP8273Up to Day 1 of Cycle 3
Phase II: Safety and tolerability of ASP8273 as assessed by 12-lead ECGUp to 18 months

including the assessment of QT intervals

Phase II: Progression-free survival (PFS)Up to 18 months
Phase II: Safety and tolerability of ASP8273 as assessed by laboratory testsUp to 18 months

Laboratory tests to be conducted are hematology, biochemistry, urinalysis, coagulation profile, lipid panel and lymphocyte subpopulation

Phase I: Safety and tolerability of ASP8273 as assessed by adverse events (AEs)Up to 18 months

An AE is defined as any untoward medical occurrence in a subject administered a study drug or has undergone study procedures and which does not necessarily have a causal relationship with this treatment. An AE can therefore be any unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product

Phase I: Safety and tolerability of ASP8273 as assessed by vital signsUp to 18 months

Vital signs to be measured includes blood pressure, pulse rate and temperature
