GS-6624 · 7 trials · 9 indications
The endpoints to be evaluated will include graded Adverse Events, laboratory abnormalities, and vital sign measurements
Progression free survival is measured as time from date of randomization to the earliest event time of death regardless of cause or first indication of disease progression.
Overall response for the study drug is defined by the reduction in bone marrow fibrosis score which is on a scale of 0-3 where 0 indicates the scattered linear reticulin with no fiber intersections representing normal marrow and 3 indicates dense increase in reticulin fibrosis with fiber intersections, often with osteosclerosis. Reduction from baseline of score indicates improvement in clinical condition.
To characterize the safety, tolerability, and pharmacokinetics (PK) of GS-6624 after multiple intravenous (IV) administrations in subjects with idiopathic pulmonary fibrosis (IPF).

| AB0024 | EXPERIMENTAL | 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. |
