Brief Summary:
This is a dose escalation, Phase 1-2 study of ABN401 in patients with advanced solid tumors, refractory metastatic disease, or refractory locally advanced disease not amenable to local therapy.

Condition or disease Intervention/treatment Phase
Advanced Solid Tumors Drug: ABN401- Escalation Phase Drug: ABN401- Expansion Phase Phase 1 Phase 2

Detailed Description:

First part of the study uses single patient cohorts at the initial dose levels, followed by a classic 3+3 design, with enrollment of 3 patients per cohort and expansion to 6 patients in the event of a dose-limiting toxicity (DLT).

The second part of the study consists of expansion cohorts with patients with c-Met amplification/mutation of interest.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 78 participants
Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 1-2 Multicenter, Open-Label, Dose-Escalation and Dose-Expansion Study to Evaluate the Safety, Pharmacokinetics, Pharmacodynamics, and Antitumor Activity of ABN401 in Patients With Advanced Solid Tumors
Actual Study Start Date : August 1, 2019
Estimated Primary Completion Date : March 31, 2021
Estimated Study Completion Date : December 31, 2023

Arm Intervention/treatment
Experimental: Escalation phase

Drug: ABN401

Route of Administration: Oral

The study will follow a single patient cohort approach for the first 3 regular dose levels followed by classic 3+3 design. The starting dose is 0.9 mg/kg.

Drug: ABN401- Escalation Phase
Dose administration: Escalation Phase The regular dose levels of ABN401 will range from 0.9 mg/kg to 54.0 mg/kg QD daily for 21 days.

Experimental: Expansion phase

Drug: ABN401

Route of Administration: Oral

Once the MTD or highest escalation cohort has been reached, or notable efficacy has been observed at a given dose level, a decision as to RP2D will be determined. Upon the establishment of RP2D, up to 4 expansion cohorts of 10-29 patients will be recruited representing various c-Met amplification or mutant tumor types of interest.

Drug: ABN401- Expansion Phase
Dose administration: Expansion Phase The expansion phase of the study will use the dose and schedule determined to be most appropriate in the dose escalation portion of the study. This may be the MTD and/or the RP2D and will consist of cohorts of patients representing various c-Met-amplification or mutant tumor types of interest.

Primary Outcome Measures :
  1. To evaluate the safety and tolerability of ABN401. [ Time Frame: Measurements at Baseline till the last day of Visit ]
    Safety and tolerability determined by abnormal clinical laboratory tests, vitals signs, physical exam, ECG parameters, Liver function tests

Secondary Outcome Measures :
  1. To determine the systemic PK of ABN401. [ Time Frame: Dose Escalation Phase: Cycle 1- Day 1, Day 2, Day 5, Day 8, Day 15; Dose Expansion Phase: Cycle 1, Day -2, Day 1, Day 2, Day 8, Day 15 ]
  2. To evaluate the effect of food on PK profile of ABN401 in expansion cohort. [ Time Frame: Cycle 1, Day -2, Day 1, Day 2, Day 8, Day 15 ]
  3. To determine preliminary estimate of ABN401 efficacy in patients with selected malignancies [ Time Frame: Screening and at every 6 weeks from C1D1 independent of cycle length ]
    Efficacy will be assessed by CT/MRI Scans of the chest, abdomen and pelvis (patients with lung, pancreatic and ovarian cancer, and if clinically indicated for patients with other malignancies)
