A Study of ASP8273 in Epidermal Growth Factor Receptor (EGFR) Tyrosine Kinase Inhibitor-Naïve Patients With Non-Small Cell Lung Cancer Harboring EGFR Mutations

Phase II Study of ASP8273 - An Open-Label, Study of the Oral Administration of ASP8273 in Epidermal Growth Factor Receptor (EGFR) Tyrosine Kinase Inhibitor-NaïvePatients With Non-Small Cell Lung Cancer Harboring EGFR Mutations

The purpose of this study is to determine the safety, the antitumor activity and the pharmacokinetics of ASP8273 in EGFR tyrosine kinase inhibitor (EGFR-TKI)-naïve patients with non-small cell lung cancer (NSCLC) harboring EGFR activating mutations.

Study Overview

• Status: Terminated
• Conditions: EGFR-TKI-naïve Patients With NSCLC Harboring EGFR Activating Mutations
• Intervention / Treatment: Drug: ASP8273 Capsules; Drug: ASP8273 Capsules A

Detailed Description

This study consists of a single-dose period (Cycle 0 lasting 3 days) and a multiple-dose period (from Cycle 1 onwards, each cycle lasting 21 days). To compare the PK between ASP8273 Capsules and ASP8273 Capsules A, enrolled subjects will receive a single oral dose of ASP8273 Capsules A on Day 1 of Cycle 0 in the single-dose period and will then be observed for 3 days (including the day of dosing). In the multiple-dose period, subjects will receive multiple oral doses of ASP8273 Capsules during each cycle lasting 21 days. From the viewpoint of PK comparison (bioavailability [BA] evaluation) between ASP8273 Capsules and ASP8273 Capsules A, data from approximately 15 subjects are sufficient for the evaluation. Therefore, if PK data of approximately 15 subjects included in BA evaluation are obtained and the sponsor judges that further acquisition of PK data is not necessary, the single-dose period will not be conducted in subjects who are enrolled thereafter (subjects not included in BA evaluation). Subjects will continue to receive treatment with ASP8273 until they meet the discontinuation criteria.

Participation Criteria

Eligibility Criteria

• Accepts Healthy Volunteers: No

Description

Inclusion Criteria:

• Patients with Eastern Cooperative Oncology Group (ECOG) Performance Status ≤ 1.
• Patients with a histologically or cytologically confirmed diagnosis of Stage IIIB or IV NSCLC.
• Patients confirmed to have the deletion of exon 19 (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).
• Patients with a life expectancy ≥ 12 weeks based on the principal investigator's/subinvestigator's judgment.

• Patients who meet all of the following requirements for laboratory tests within 7 days before enrollment. When 2 or more test results for a single parameter are found within the specified period, the last data before enrollment should be used for assessment.

  • Neutrophil count: ≥ 1,500/mm3
  • Platelet count: ≥ 75,000/mm3
  • Hemoglobin: ≥ 9 g/dL
  • Serum creatinine: < 1.5 mg/dL
  • Total bilirubin (TBL): < 1.5 × the upper limit of normal (ULN) at the site (this does not apply to patients with Gilbert syndrome)
  • Aspartate aminotransferase (AST) and alanine aminotransferase (ALT): < 2.5 ×the ULN at the site

• Patients who meet all the following requirements for prior treatment for NSCLC:

  • Patients who have not received previous treatment with EGFR-TKIs*1 *1: Erlotinib, gefitinib, afatinib, and EGFR-TKIs under clinical investigation (e.g.,neratinib, dacomitinib). EGFR-TKIs that can inhibit EGFR with the T790Mmutation (e.g., ASP8273, CO-1686, AZD9291) are also included.
• Patients who have not received more than one regimen of previous drug treatment (however, this does not include preoperative or postoperative therapies used within at least a 6-month interval after the last dose of the treatment).
• Patients who have at least 1 measurable lesion based on Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1.

Exclusion Criteria:

• Patients with 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).
• Patients with a history of or concurrent interstitial lung disease.
• Patients who have received previous treatment with intended antitumor effects or treatment with another investigational drug/medical device within 14 days before the start of the study treatment.
• Patients who have received transfusion or hematopoietic growth factor therapy within 14 days prior to the start of the study treatment.
• Patients who have received oral or intravenous corticosteroids within 7 days prior to the start of the study treatment (except to treat or prevent an allergic reaction).
• Patients who are scheduled to undergo a surgical procedure during the course of the study or the patient still has an unhealed wound after previous surgery.

• Patients who have received moderate CYP3A inhibitors within 9 days prior to the start of the study treatment (only for subjects included in BA evaluation).
