Gilead Sciences Identifier:
First received: March 24, 2011
Last updated: May 2, 2012

Analysis of safety, tolerability, and PK data will provide information that will guide future development of AB0024.

Condition Intervention Phase
Neoplasms Drug: AB0024 Phase 1

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 1, First-in-Human Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of AB0024 in Adult Patients With Advanced Solid Tumors

Further study details as provided by Gilead Sciences:

Primary Outcome Measures:
  • To characterize the safety, tolerability, and pharmacokinetics (PK) of AB0024 after multiple intravenous (IV) administrations in patients with advanced solid tumors. [ Time Frame: Day 71 ]

Secondary Outcome Measures:
  • To measure the tumor response by modified Response Evaluation Criteria in Solid Tumors (RECIST) and to evaluate the formation of anti-AB0024 antibodies. [ Time Frame: Day 71 ]

Enrollment: 32
Study Start Date: June 2010
Study Completion Date: March 2012
Primary Completion Date: March 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: AB0024

The starting dose for Part A will be 1 mg/kg. Subsequent doses of 3, 10, and 20 mg/kg are planned. Three to 6 patients will be enrolled using a 3 + 3 design. Doses of AB0024 will be administered on Days 1, 15, 29, and 43 to characterize the safety, tolerability, and PK.

The dose expansion phase of the study will begin upon completion of the dose escalation phase. Up to 20 patients will be enrolled into one or two cohorts of Part B. The first expansion cohort will be dosed up to the MTD defined as the highest dose level with an observed incidence of DLT in <33% of patients enrolled from Part A.

Drug: AB0024
Comparison of different dosages of drug

Detailed Description:

This is a first-in-human, open-label, sequential dose escalation study to evaluate AB0024 in patients with advanced solid tumors. The study will consist of two parts: Part A will be a dose escalation, and Part B will be a dose expansion.The primary objective of this study is to characterize the safety, tolerability, and PK of AB0024 after multiple IV administrations in patients with advanced solid tumors. The secondary objectives are to measure the tumor response by modified RECIST and to evaluate the formation of anti-AB0024 antibodies.

Patients will receive infusions of AB0024 every two weeks. Patients will be seen weekly for safety assessments and collection of blood samples. Patients who do not show evidence of disease progression by clinical assessment or by CT or MRI may continue receiving AB0024 every 2 weeks until disease progression (clinical or radiographic), study drug intolerance, or withdrawal of consent.
