Inclusion Criteria
  • Subjects ≥ 18 years at the first screening examination/visit.

  • Subjects with advanced histologically or cytologically confirmed solid tumors (see below) refractory to or relapse from at least two previous therapies.

  • Tumor types expected to express lower levels of FcRn relative to normal tissue including: STS, TNBC, cervical cancer, NSCLC, ovarian cancer, and KRAS mutated pancreatic ductal adenocarcinoma without requirement for testing FcRn level.

  • Disease that is considered measurable by RECIST v1.1.

  • Eastern Cooperative Oncology Group (ECOG) performance status of 0-2.

Primary Outcome Measures
NameTimeMethod
Overall Response Rate (ORR) by RECIST v1.12 Years

Sum of Complete Response (CR) and Partial Response (PR) by RECIST v1.1. Per Response Evaluation Criteria in Solid Tumors (RECIST v1.1): Complete Response (CR) is defined as the disappearance of all target lesions; Partial Response (PR) is defined as a 30% decrease in the sum of diameters of target lesions. ORR = CR + PR

Disease Control Rate (DCR) by RECIST v1.12 Years

Disease Control Rate (DCR) defined as Sum of Stable Disease (SD) + Partial Response (PR) + Complete Response (CR) by RECIST v1.1. Per Response Evaluation Criteria in Solid Tumors (RECIST v1.1): Complete Response (CR) is defined as the disappearance of all target lesions; Partial Response (PR) is defined as a 30% decrease in the sum of diameters of target lesions; Progressive Disease (PD is defined as an increase of at least 20% in the sum of the longest diameters of the target lesions, with an absolute increase of at least 5 mm, or the appearance of one or more new lesions. Stable Disease (SD) is defined as a tumor that has neither shrunk sufficiently to qualify as a partial response (PR) nor increased sufficiently to qualify as progressive disease (PD).
