Details and patient eligibility
About
2.1 Primary Objectives
- To measure the human dosimetry of 64Cu-DOTA-U3-1287 in subjects with advanced solid tumors (Cohort 1 only)
- To calculate HER3 receptor occupancy (via quantification of the tumor-localized PET signal produced by 64Cu-DOTA-U3-1287 in the absence and presence of competing unlabeled U3-1287 in subjects with advanced solid tumors (Cohorts 2 through 5))
- To determine the safety and tolerability of 64Cu-DOTA-U3-1287 (all cohorts)
2.2 Secondary Objectives
- To determine the relationship between U3-1287 serum concentration and HER3 receptor occupancy (as measured by PET/CT) in subjects with advanced solid tumors
- To measure the tumor response rate as defined by Response Evaluation Criteria in Solid Tumors (RECIST 1.1) in subjects with advanced solid tumors treated with U3-1287 (Part 2 only)
- To characterize the PK exposure of U3 1287 when administered intravenously to patients with advanced solid malignancies.
- To measure the rate of anti-U3-1287 human antibody development in subjects with advanced solid tumors treated with U3 1287 monotherapy
2.3 Exploratory Objectives
- To assess tumor volume changes after U3-1287 treatment by CT or magnetic resonance imaging (MRI) (Part 2 only)
- To assess blood, body fluid/tissue, and tumor specimens for potential biomarkers (e.g., proteins and transcripts) that predict response to U3-1287
- To obtain tumor samples for DNA extraction for analysis of potential predictors of response to U3-1287 and any related genes as suggested by emerging data

Inclusion criteria
-
Patient must have measurable disease as defined by RECIST 1.1, with the additional requirement of at least one lesion ≥ 1.5 cm on CT scan or detectable on FDG-PET performed within 30 days prior to screening
-
Patient must have a tumor where HER3 expression is expected (this includes breast, colon, lung, prostate, ovarian, cervical, endometrial, gastric, pancreatic, bladder, head and neck, liver, and esophageal cancer, but other tumors will be considered based on emerging HER3 expression data)
-
Patient must have an Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2
-
Patient must have pathologically documented, definitively diagnosed, advanced solid tumors that are refractory to standard treatment or for which no curative therapy is available
-
Patient must have adequate hematologic and organ function as follows:
- Absolute neutrophils count (ANC) ≥ 1.5 x 109/L
- Platelet count ≥ 100 x 109/L
- Hemoglobin ≥ 9 g/dL
- Serum creatinine ≤ 2 x IULN
- AST ≤ 2.5 x IULN (≤ 5.0 x IULN if attributable to liver metastasis)
- ALT ≤ 2.5 x IULN (≤ 5.0 x IULN if attributable to liver metastasis)
- Alkaline phosphatase ≤ 2.0 x ULN (if bone or liver metastases are present, < 5 x ULN)
- Total bilirubin ≤ 1.5 IULN
- Amylase or lipase ≤ 2.0 x IULN
- Prothrombin time (PT) or partial thromboplastin time (PTT) ≤ 1.5 x IULN
-
Patient must have an LVEF of ≥ 50%
-
Patient must be ≥ 18 years old
-
Women of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control, abstinence) prior to study entry, for the duration of study participation, and for 6 months following the completion of study treatment; should a woman become pregnant or suspect she is pregnant while participating in this study, she must inform her treating physician immediately.
-
Patient must be willing and able to undergo the imaging studies outlined in the protocol (in the opinion of the investigator)
-
Patient must be able to understand and willing to sign an institutional review board (IRB) approved informed consent form
-
Patient must have archival tissue available for HER3 expression analysis
Exclusion criteria
- Patient must not have the liver and/or spleen as the only site(s) of disease (as PET/CT imaging of 64Cu-DOTA-U3-1287 may be difficult in these anatomic locations)
- Patient must not have any unresolved toxicities > grade 1 with the exception of grade 2 lymphopenia and/or alopecia from prior anti-cancer therapy Note: Grade 2 or 3 toxicities from prior therapy that are considered irreversible (defined as having been present and stable for > 3 months), such as ifosfamide-related proteinuria, or treatment related neuropathy, may be allowed if they are not otherwise described in the exclusion criteria AND the PI and Daiichi Sankyo both agree that this patient may be included
- Patient must not have untreated or symptomatic primary central nervous system metastases or symptoms of brain metastases; any stereotactic radiation or whole brain radiation therapy must have been completed at least 4 weeks prior to study entry
- Patient must not have ascites or pleural effusion requiring medical intervention
- Patient must not have had a myocardial infarction within 6 months of Day 1 or any unstable or uncontrolled disease/condition related to or impacting cardiac function (i.e., unstable angina, congestive heart failure, New York Heart Association > class II, uncontrolled hypertension [diastolic > 95 mmHg; systolic >140 mmHg])
- Patient not have cardiac arrhythmia or clinically significant ECG abnormalities
- Patient must not be known to be positive for human immunodeficiency virus (HIV) infection, hepatitis C virus, or chronic active hepatitis B infection
- Patient must not have a known sensitivity to any components of the formulation
- Patient must not be receiving any concomitant antitumor treatment or chemotherapy, radiotherapy, and hormonal therapy (with the exception of Lupron for prostate cancer and SERMS for breast cancer subjects) within 4 weeks of Day 1 (6 weeks for nitrosoureas or mitomycin and 2 weeks for small molecule tyrosine kinase inhibitors)
- Patient must not be receiving any concomitant immunosuppressant therapy (cyclosporine A, FK506, etc., or chronic > 5 mg/d of prednisone)
- Patient must not be receiving any other concomitant investigational procedures and must not have participated in any other clinical trial with an investigational device or agent within 4 weeks of the first dose of 64Cu-DOTA-U3-1287
- Patient must not have had any previous exposure to U3-1287
- Patient must not have had any previous treatment with HER3 antagonists
- Patient must not have had G-CSF support therapy within 2 weeks of Day 1
- Patient must not have received red blood cell (RBC) transfusion within 2 weeks of Day 1
- Patient must not have received platelet transfusion within 2 weeks of Day 1
