Not Recruiting

Trial ID: NCT04190628

Purpose

This is a Phase I, First-In-Human, open label, dose escalation and dose expansion study to evaluate the safety, tolerability, pharmacokinetics, and preliminary anti-cancer activity of ABM-1310 in adult patients with locally advanced or metastatic solid tumors who have no effective standard treatment options available, as monotherapy in patients with documented BRAF V600 mutation, or in combination with cobimetinib (Cotellic®) in adult patients who have documented BRAF mutation and progressive disease or intolerance to at least one prior line of systemic therapy.

Official Title

A Phase I, First-In-Human, Multicenter, Open-Label Dose Escalation and Dose Expansion Study of ABM-1310, as a Monotherapy and a Combination Therapy, Administered Orally in Adult Patients With Advanced Solid Tumors Harboring BRAF Mutations

   metastatic solid tumor malignancy that has either (a) progressed on at least one line
   of prior standard systemic therapy, (b) for which no standard therapy exists, or (c)

         positive BRAF mutation

   Patients with active or stable brain metastasis that are asymptomatic, or that are
   symptomatic treated with a total daily dose of no more than 4 mg of dexamethasone (or
   equivalent) that is stable or tapering for at least 2 weeks prior to first treatment

   within 2 weeks prior to first treatment.

   3. Must have at least one measurable lesion as defined by RECIST V1.1 criteria for solid
   tumors or the RANO criteria for primary CNS tumors, such as gliomas.

      - For solid tumor with Brain Metastases:

      - Measurable brain lesions that are 0.5 - 3 cm in longest diameter as defined by
      the modified RECIST V1.1 criteria are allowed.

      - Brain lesion size > 3 cm is not eligible.

   4. ECOG performance status of 0 or 1 or Karnofsky performance status of ≥ 70

   5. Adequate organ function confirmed at screening and within 28 days of initiating
   treatment, as evidenced by:

      - Absolute Neutrophil Count (ANC) ≥ 1.0 x 10^9/L

      - Hemoglobin (Hgb) ≥ 9 g/dl

      - Platelets (Plt) ≥ 100 x 10^9/L

      - AST/ALT ≤ 2.5 x Upper Limit of Normal (ULN) or ≤ 5.0 x ULN if liver metastases
      are present

      - Total bilirubin ≤ 1.5 x ULN, or direct bilirubin
      bilirubin levels >1.5 ULN

      - Serum creatinine <1.5 x ULN or measured or calculated (per institutional
      standard) creatinine clearance of > 60 mL/min.

   6. Negative pregnancy test within 72 hours before starting study treatment in all
   pre-menopausal women and women <12 months after the onset of menopause

   7. Male and female subjects must agree to take sufficient contraceptive methods to avoid
   pregnancy before first dose of study treatment, during the study, and for at least 3
   months after ceasing study treatment

Exclusion Criteria:

   1. Women who are pregnant or breast-feeding

   2. Women of child-bearing potential (WOCBP) who does not use adequate birth control

   3. Patients with any hematologic malignancy. This includes leukemia, lymphoma, and
   multiple myeloma

   4. Have a second primary malignancy that, in the judgment of the investigator, may affect
   the interpretation of results

   6. Patients with history of stroke ≤ 6 months prior to starting study drug
