Primary Outcome Measures	Measure Description	Time Frame
Objective Response Rate	Tumor assessments were evaluated at baseline by computerized tomography (CT) or magnetic resonance imaging (MRI). The primary objective of this study was to determine the overall objective response rate (ORR) per investigator assessment, defined as confirmed complete response (CR; disappearance of all target lesions) + partial response (PR; at least a 30% decrease in the sum of the longest diameter of target lesions) by RECIST v1.1, for seribantumab monotherapy (3,000 mg QW) in patients with centrally confirmed NRG1 fusion.	Up to 12 months

Secondary Outcome Measures	Measure Description	Time Frame

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person’s general health condition or prior treatments.

Ages Eligible for Study:
ALL

Sexes Eligible for Study:
18 Years

Accepts Healthy Volunteers:

Locally-advanced or metastatic solid tumor with an NRG1 gene fusion identified through molecular assays, such as PCR, NGS (RNA or DNA) or FISH, by a CLIA-certified or similarly accredited laboratory
Availability of fresh or archived FFPE tumor sample to be submitted to a central laboratory for confirmation of NRG1 gene fusion status
Patients should have received a minimum of one prior standard therapy appropriate for their tumor type and stage of disease, progressed or been nonresponsive to these available therapies, with no further available curative therapy options
≥ 18 years of age
ECOG performance status (PS) 0, 1 or 2
Patients must have at least one measurable extra-cranial lesion as defined by RECIST v1.1
Adequate hepatic function defined as:
Serum AST and serum ALT < 2.5 × upper limit of normal (ULN), or AST and ALT < 5 × ULN if liver function abnormalities due to underlying malignancy
Total bilirubin < 2.0 ULN. Subjects with a known history of Gilberts Disease and an isolated elevation of indirect bilirubin are eligible
Adequate hematologic status, defined as:
Absolute neutrophil count (ANC) ≥1.5 × 109/L not requiring growth factor support for at least 7 days prior to Screening, and
Platelet count ≥100.0×109/L not requiring transfusion support for at least 7 days prior to Screening

Prior to initiation of seribantumab treatment, patients must have recovered from clinically significant toxicities from prior anticancer or investigational therapy
Any other active malignancy requiring systemic therapy
Known hypersensitivity to any of the components of seribantumab or previous CTCAE grade 3 or higher hypersensitivity reactions to fully human monoclonal antibodies
