Brief Summary:

This is an open-label Phase 1 dose escalation study of OMP-54F28 in subjects with a solid tumor for which there is no remaining standard curative therapy. Subjects will be assessed for safety, immunogenicity, pharmacokinetics, biomarkers, and efficacy. No formal interim analyses will be performed.

Prior to enrollment, subjects will undergo screening to determine study eligibility. Upon enrollment, subjects will receive OMP-54F28 until disease progression. All subjects will receive Vitamin D3 daily and calcium carbonate twice daily from Day 0 through 30 days following the discontinuation of OMP-54F28.

Dose escalation will be conducted to determine the maximum tolerated dose (MTD). Subjects will be dosed at 0.5, 1, 2.5, 5, and 10 mg/kg administered IV once every 3 weeks. No dose escalation or reduction will be allowed within a dose cohort. Intermediate doses (i.e., doses between the dose levels listed above) may also be tested upon agreement with the investigators and the study sponsor. In addition, alternate dosing schedule cohorts of OMP-54F28 (eg. every 4 week or every 6 week dosing) can be studied upon agreement with the investigators and the study sponsor. These alternative less frequent dosing schedules may be evaluated if emerging data suggest that once every 3 week dosing results in tolerability concerns. The first 2 subjects enrolled in a cohort will not be treated on the same day. The dose may be administered at any time during the day. Three subjects will be treated at each dose level if no dose-limiting toxicities (DLTs) are observed. If 1 of 3 subjects experiences a DLT, that dose level will be expanded to 6 subjects. If 2 or more subjects experience a DLT, no further subjects will be dosed at that level and 3 additional subjects will be added to the preceding dose cohort unless 6 subjects have already been treated at that dose level. Subjects will be assessed for DLTs from Days 0-28. Dose escalation for newly enrolled subjects, if appropriate, will occur after all subjects in a cohort have completed their Day 28 DLT assessment. Subjects who have a >2-fold increase of their fasting β-CTX or a decline of >3% in their bone mineral density (BMD) from screening or a T-score decline to <-2.5 in the total femur or L1-L4 DEXA scan measurement will be started on zoledronic acid. Subjects with stable disease or a response at Day 56 will be allowed to continue to receive OMP-54F28 until disease progression. An additional 6 subjects will be enrolled in an expansion cohort at the highest dose level that results in <2 of the 6 subjects experiencing a Grade 3 (not including a Grade 3 infusion reaction that resolves in 24 hours) or Grade 4 adverse event (DLT). Tumors of particular interest for inclusion in the expansion cohort include sarcomas, basal cell carcinoma, ovarian cancer, desmoid tumors and prostate cancer given the known importance of the Wnt pathway in these malignancies.

Official Title: A Phase 1 Dose Escalation Study of OMP-54F28 in Subjects With Solid Tumors
Study Start Date : June 2012
Actual Primary Completion Date : August 2016
Actual Study Completion Date : June 2017

Intervention Details:
  • Biological: OMP-54F28
    dose escalation of 0.5, 1, 2.5, 5, and 10 mg/kg administered IV once every 3 weeks

Primary Outcome Measures :
  1. • To determine the safety of OMP-54F28 in subjects with previously treated solid tumors [ Time Frame: Subjects will be assessed for dose limiting toxicities from Days 0-28. Adverse events will be reported through 30 days after the last dose. ]

Secondary Outcome Measures :
  1. To determine the pharmacokinetics of OMP-54F28 in subjects with previously treated solid tumors [ Time Frame: Baseline,end of infusion,0.5,1,3,6,24, and 72 hours post-infusion (1st infusion) 0.5, 1, 3, 6, 24, 72, and 168 hours (3rd infusion),before/end 2nd infusion,Days 7, 14, 28, and 35. After termination: Weekly for the first 4 weeks, then at Week 8 and 12 ]
    The pharmacokinetic (PK) parameters to be assessed are study drug half-life (t½), volume of distribution (Vd), and clearance (CL).

  2. To determine the immunogenicity of OMP-54F28 in subjects with previously treated solid tumors [ Time Frame: Subjects will be assessed during screening ,every 4 weeks while on study drug, at the time of treatment termination, then weekly for the first 4 weeks, then at Week 8 and 12 following discontinuation of study drug ]
  3. To assess the preliminary efficacy of OMP-54F28 in subjects with previously treated solid tumors [ Time Frame: Every 56 days until disease progression ]
    The response outcome in patients will be determined.
