A Study of IMC-TR1 in Participants With Advanced Solid Tumors

This is the first-in-human Phase 1 study of IMC-TR1.

Inclusion criteria

• Part A and Part B: Participants must be appropriate candidates for experimental therapy, with a solid tumor that has failed standard therapy or for which no standard therapy is available, and evidence of progressive disease

• Part A only: Participants must have histological or cytological evidence of a solid tumor which is advanced and/or metastatic
• Part B only: Participants who have failed first-line therapy/standard of care and have histological or cytological evidence of a cancer type for which evidence of activity was observed during Part A or for which preclinical evidence of potential activity has been observed
• Have the presence of measurable or nonmeasurable disease as defined by the Response Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST 1.1)

• Part A only: Participants may have measurable or nonmeasurable disease
• Part B: Participants must have measurable disease
• Have adequate organ function including: Hematologic, Hepatic, Albumin, Coagulation and Renal function
• Have a performance status of ≤ 1 on the Eastern Cooperative Oncology Group (ECOG) scale
• Have discontinued previous treatments for cancer and recovered from the acute effects of therapy
• Males and females with reproductive potential must agree to use medically approved contraceptive precautions during the study and for 3 months following the last dose of study drug
• Females with child bearing potential must have had a negative serum pregnancy test and must not be breastfeeding
• Have an estimated life expectancy that is > 3 months

Exclusion criteria

• Have clinically significant cardiac disease, including:

• Myocardial infarction within 6 months prior to study entry, unstable angina pectoris, congestive heart failure, or uncontrolled hypertension

• Are currently using or has received a systemic thrombolytic agent within 28 days prior to enrollment
• Are receiving:

• full-dose warfarin
• intravenous heparin or low-molecular-weight heparin
• chronic daily treatment with aspirin at a dose greater than 325 mg per day or nonsteroidal anti-inflammatory medications known to inhibit platelet function
• Have evidence of retinal disease or are a monocular participant
• Have received a solid organ transplant, bone marrow transplant or stem cell transplant
• Have symptomatic central nervous system (CNS) malignancy or untreated metastasis
• Have acute or chronic leukemia
• Have a known active fungal, bacterial, and/or viral infection including human immunodeficiency virus or viral hepatitis requiring treatment
• Has a positive fecal occult blood test within 14 days prior to enrollment
