Study Details

Study Description

Brief Summary

This is a phase 2 study that will assess the efficacy of AMG 337 in subjects with advanced or metastatic clear cell sarcoma that contains the EWSR1-ATF1 gene fusion.

Condition or Disease Intervention/Treatment Phase
  • Drug: AMG 337
Phase 2

Detailed Description

The phase 2 single arm study will assess efficacy of AMG 337 (based on confirmed ORR) in subjects with advanced or metastatic clear cell sarcoma that contains the EWSR1-ATF1 gene fusion, as determined by fluorescent in situ hybridization (FISH) or other diagnostic methods and confirmed by RNA sequencing (RNAseq).

Arms and Interventions

Arm Intervention/Treatment
Experimental: AMG 337

AMG 337 will be administered in patients with advanced or metastatic clear cell sarcoma

Drug: AMG 337
6-{(1R)-1-[8-fluoro-6-(1-methyl-1H-pyrazol-4-yl)[1,2,4]triazolo[4,3-a]pyridin-3-yl]ethyl}-3-(2-methoxyethoxy)-1,6-naphthyridin-5(6H)-one•hydrate (1:1)

Outcome Measures

Primary Outcome Measures

  1. Objective Response Rate (ORR) [1 year]

    Confirmed ORR (confirmed complete response or partial response) will be evaluated in accordance with RECIST Version 1.1 by BICR.

Secondary Outcome Measures

  1. Incidence of Treatment-Emergent Adverse Events (Safety And Tolerability) [1 year]

    To evaluate the safety of AMG 337 based on grade 3 or 4 non-hematologic toxicity.

  2. Progression-free Survival (PFS) [1 year]

    To determine PFS, evaluated in accordance with RECIST Version 1.1 BICR.

  3. Overall Survival (OS) [1 year]

    To determine OS, defined as the time from the date of the first administration of therapy to the date of death.

  4. Duration of Response (DOR) [1 year]

    To determine DOR, measured by RECIST Version 1.1 by BICR.

  5. Disease Control Rate (DCR) [4 months]

    To determine DCR (confirmed CR, PR, or SD) lasting for at least 4 months by BICR.

All
Accepts Healthy Volunteers:
No
Inclusion Criteria:
  1. Able to understand and provide a signed informed consent that fulfills the relevant Institutional Review Board (IRB) or Independent Ethics Committee (IEC) guidelines.

  2. Able to attend required study visits and return for adequate follow-up, as required by this protocol.

  3. Able to self-administer AMG 337 as a whole capsule by mouth every day.

  4. Age ≥ 16 years.

  5. Histologically confirmed, unresectable, locally advanced or metastatic tumors that contain the EWSR1-ATF1 gene fusion, as determined by fluorescent in situ hybridization (FISH) or other diagnostic methods and confirmed by RNA sequencing (RNAseq).

  6. Have measurable disease evaluable in accordance with RECIST Version 1.1.

  7. Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2.

  8. Must have a recent Formalin-fixed paraffin-embedded (FFPE) tumor biopsy specimen that was obtained following the conclusion of the most recent anticancer treatment. If an historic specimen is not available, the subject must be willing to undergo a biopsy during the screening period.

  9. Must be willing to undergo a biopsy during the treatment period, if considered safe by the investigator.

  10. Ability to attend required study visits and return for adequate follow-up, as required by this protocol.

  11. Hematologic function, as follows:

  12. Absolute neutrophil count (ANC) ≥ 1.5 × 109/L.

  13. Platelet count ≥ 50 × 109/L.

  14. Hemoglobin > 8 g/dL.

  15. Prothrombin time (PT) or partial thromboplastin time (PTT) < 1.5 × upper limit of normal (ULN), except for subjects on anticoagulation therapy for venous thromboembolism.

  16. Renal function, as follows:

  1. Calculated creatinine clearance > 30 mL/min.
  1. Hepatic function, as follows:

  2. Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) < 2.5 × ULN and total bilirubin < 1.5 × ULN.

  3. Alkaline phosphatase (ALP) < 2 × ULN (≤ 5 × ULN if bone or liver metastases are present)

  4. Agreement to practice effective contraception (both male and female subjects, if the risk of conception exists).

Exclusion Criteria:
  1. Assessed by the investigator to be unable or unwilling to comply with the requirements of the protocol.

  2. Inability to attend required study visits and return for adequate follow-up, as required for this protocol.

  3. Known hypersensitivity to any component of the study medication(s).

  4. Women who are nursing, pregnant, or planning to become pregnant during the duration of the study.

  5. Current diagnosis or history of a second neoplasm, except the following:

  1. Adequately treated non-melanoma skin cancer, curatively treated in situ disease, or other solid tumors curatively treated with no evidence of disease for ≥ 2 years.
  1. History of bleeding diathesis.

  2. Uncontrolled hypertension (systolic > 160 mmHg and/or diastolic > 100 mmHg) or clinically significant cardiovascular disease, cerebrovascular accident/stroke, or myocardial infarction within 6 months before study day 1; unstable angina; congestive heart failure of New York Heart Association grade 2 or higher; or serious cardiac arrhythmia requiring medication.

  1. Grade 2 toxicities from prior anti-tumor therapy that are considered irreversible (defined as having been present or stable for > 4 weeks), such as stable grade 2 peripheral neuropathy or ifosfamide-related proteinuria, may be allowed if they are not otherwise described in the exclusion criteria.
