Study of ASN003 in Subjects With Advanced Solid Tumors

NCT02961283

Description:

The study is divided into two parts. The first part of the study will test various doses of ASN003 to find out the highest safe dose to test in three specific groups. The second part of the study will test how well ASN003 can control cancer. Subjects will be enrolled into one of three groups. Group 1: metastatic or recurrent melanoma with documented BRAFV600 mutation (n=20 evaluable patients) Group 2: metastatic colorectal cancer (CRC), or advanced non-small cell lung cancer (NSCLC) with documented BRAFV600 mutation (n=14 evaluable patients) Group 3: advanced solid tumors with documented PI3K pathway alterations (PIK3CA mutation or PTEN loss) (n=14 evaluable patients)

Purpose

The study is divided into two parts. The first part of the study will test various doses of ASN003 to find out the highest safe dose to test in three specific groups.

The second part of the study will test how well ASN003 can control cancer. Subjects will be enrolled into one of three groups.

Group 1: metastatic or recurrent melanoma with documented BRAFV600 mutation (n=20 evaluable patients) Group 2: metastatic colorectal cancer (CRC), or advanced non-small cell lung cancer (NSCLC) with documented BRAFV600 mutation (n=14 evaluable patients) Group 3: advanced solid tumors with documented PI3K pathway alterations (PIK3CA mutation or PTEN loss) (n=14 evaluable patients)

Detailed Description

The study will be conducted in two parts. Part A is a dose escalation study to determine a safe and tolerable dose of ASN003 for subjects with advanced solid tumors. Part A will also characterize the pharmacokinetics and pharmacodynamics of ASN003 through blood sampling and optional biopsies.. Part B will only enroll subjects in three groups:

Group 1: subjects who have metastatic or recurrent melanoma with the BRAFv600 mutation.

Group 2: subjects who have advanced or metastatic non-small cell lung cancer, or colorectal cancer with the BRAFv600 mutation.

Group 3: subjects who have advanced or metastatic cancers with phosphatidylinositide 3-kinases (PI3K) mutations, or phosphatase and tensin homolog (PTEN) loss mutation. Subjects will be treated with the highest safe and tolerable dose determined in Part A of the study to determine preliminary efficacy. Subjects may continue to receive ASN003 for up to 1 year in the absence of severe side effects or disease progression.

    Inclusion Criteria:

    - written informed consent obtained prior to any study-related procedures.

    - Eastern Cooperative Oncology Group Performance Status: 0-1

    - Part A only: Histologically or cytologically confirmed metastatic and/or advanced solid tumors with documented progressive disease for whom no further standard therapy is indicated.

    - Part B only: 5. Histologically or cytologically confirmed, molecularly selected (i.e. BRAFV600 positive and/or PI3K mutation positive) advanced solid tumors. Prior molecular characterization should be based using a regulatory approved assay or analytically validated assay.

    - Group 1: BRAFV600 positive metastatic or recurrent melanoma after failure of prior treatment with standard therapy such as a checkpoint inhibitor and an approved B-RAF inhibitor (vemurafenib or dabrafenib)

    - Group 2: BRAFV600 positive metastatic colorectal carcinoma (CRC), or advanced non-small cell lung carcinoma (NSCLC) after failure of at least two lines of prior standard therapy or for whom no further standard therapy is indicated.

    - Group 3: Advanced solid tumors with PI3K pathway alterations (PIK3CA mutation or PTEN loss) after failure of at least one line of prior standard therapy or for whom no further standard therapy is indicated. Prior treatment may not include inhibitors of the PI3K pathway.

    - Screening hematology values of the following: absolute neutrophil count ≥ 1000/μL, platelets ≥ 100,000/μL, hemoglobin ≥ 10 g/dL (without transfusion support);

    - Screening chemistry values of the following: alanine aminotransferase (ALT) and aspartate transaminase (AST) ≤ 3.0 × upper limit of the normal reference range (ULN), total bilirubin ≤ 2 × ULN, creatinine ≤ 1.5 × ULN, fasting blood glucose < 140 mg/dL, hemoglobin A1C ≤ ULN, albumin ≥ 2.8 g/dL.
