Study Endpoints

Primary Endpoints

Change From Baseline in MQC on Liver Biopsy at Week 96
Baseline; Week 96
Percentage of Participants Experiencing Treatment-Emergent Adverse Events
First dose date up to Week 24 plus 30 days
Incidence of adverse events on multiple, escalating IV doses of simtuzumab
Through Week 14

The endpoints to be evaluated will include graded Adverse Events, laboratory abnormalities, and vital sign measurements

Progression free survival
Up to 3 years

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.

Rate of Clinical Response as Defined by the Percentage of Participants With Reduction at Week 24 From Baseline in the Bone Marrow Fibrosis Score
Baseline; Week 24

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

Simtuzumab 700 mg (randomized)EXPERIMENTALParticipants will receive simtuzumab 700 mg plus gemcitabine in cycles of 28 days for up to 3 years.
Placebo (randomized)PLACEBO_COMPARATORParticipants will receive placebo to match simtuzumab plus gemcitabine in cycles of 28 days for up to 3 years.
Simtuzumab 200 mgEXPERIMENTALParticipants in Stage 1 of study will receive simtuzumab 200 mg for up to 24 weeks. Treatment could be continued if there is evidence of clinical benefit as judged by the treating physician.
Simtuzumab 700 mgEXPERIMENTALParticipants in Stage 1 of study will receive simtuzumab 700 mg for up to 24 weeks. Treatment could be continued if there is evidence of clinical benefit as judged by the treating physician.
Simtuzumab 200 mg+RuxolitinibEXPERIMENTALIn Stage 2, participants on stable doses of ruxolitinib will receive simtuzumab 200 mg for at least 24 weeks. Treatment could be continued if there is evidence of clinical benefit as judged by the treating physician.
Simtuzumab 700 mg+RuxolitinibEXPERIMENTALIn Stage 2, participants on stable doses of ruxolitinib will receive simtuzumab 700 mg for at least 24 weeks. Treatment could be continued if there is evidence of clinical benefit as judged by the treating physician.

Experimental: GS-6624 200mgEXPERIMENTAL -
AB0024EXPERIMENTALThe 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.
