This is a single-arm, open-label study to assess the safety, pharmacokinetics, pharmacodynamics, and preliminary efficacy of BMN 673 in patients with advanced tumors with DNA-repair pathway deficiencies. There will be 2 parts to the study: a dose escalation phase in which the maximum tolerated dose will be defined, and a dose expansion phase.

Primary Outcome Measures:
  • The primary outcome of this study is to determine the maximum tolerated dose (MTD) of daily oral BMN 673 [ Time Frame: Assessed after each visit until completion of Part 1 (Estimated duration is 12-18 months) ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Number of participants with adverse events [ Time Frame: Assessed after each visit until completion of the study (Estimated duration is 24-30 months) ] [ Designated as safety issue: Yes ]
  • Determine the pharmacokinetic (PK) profile of BMN 673 [ Time Frame: Assessed at each visit in cycle 1 - 5 (Estimated duration is 24 months) ] [ Designated as safety issue: No ]
    Sample collection times vary per visit. PK parameters that will be evaluated include: maximum concentration (Cmax), minimum concentration (Cmin), time to maximum plasma concentration (Tmax), area under the curve from 0 to last quantifiable sampling point post-dose (AUC0-inf), are under the curve extrapolated to infinity (AUC0-last), half life (t1/2), systemic clearance (CL/f) and volume of distribution (VZ/f)

  • Determine the Recommended Phase 2 Dose (RP2D) of oral daily BMN 673 [ Time Frame: Assessed after each visit until completion of the study (Estimated duration is 24-30 months) ] [ Designated as safety issue: No ]
  • Assess preliminary efficacy of BMN 673 by Response Rate, based on RECIST (Response Evaluation Criteria In Solid Tumors) [ Time Frame: Assessed approximately every 8 weeks (Estimated duration is 24-30 months) ] [ Designated as safety issue: No ]

Estimated Enrollment: 85
Study Start Date: December 2010
Estimated Primary Completion Date: December 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: BMN 673 Drug: BMN 673
Oral capsule with multiple dosage forms given once daily
