GNS561Dose Expansion


This is a first in human, open-label dose escalation study to investigate the safety, tolerability and pharmacokinetics of GNS561 in patients Primary and Secondary liver cancer

Detailed Description

      This is a multicenter, open-label, uncontrolled, repeat-dose Phase 1/2a study designed to
      evaluate the safety profile and to determine the recommended Phase 2 dose of GNS561 in
      patients with advanced primary and secondary liver cancer. This study will enroll
      approximately 50 patients and consists of 2 parts: Phase 1(dose escalation) and Phase 2
      (expansion). All patients will be treated until the occurrence of an unacceptable toxicity,
      disease progression, or withdrawal of consent. In this study a treatment cycle is defined as
      4 weeks (28 days). Patients are to take their assigned dose of GNS561, in the Morning and in
      the evening at the same time everyday, following a meal.

Trial Arms

Dose escalationExperimentalDose escalation using 3+3 design with dose limiting toxicity (DLT) observation period of 28 days.
  • GNS561
Dose ExpansionExperimentalAdditional patients will be enrolled into the recommended dose. These additional patients will undergo all of the same assessments as the patients enrolled in dose escalation with the exception of PK sampling.
  • GNS561

         12. Women patients of childbearing potential must have a negative serum/urine pregnancy
             test at screening and baseline, and be willing to use a medically acceptable form, as
