| Critètes d'éligibilité |
- Informed consent form signed voluntarily before any study-related procedure is performed,indicating that the patient understands the purpose of, and procedures required for, the study and is willing to participate in the study.
- Males and females ≥ 18 years of age.
- Eastern Cooperative Oncology Group performance status of 0 to 1.
- HER2-positive locally advanced or metastatic breast cancer refractory to standard cancer treatment or HER2-positive locally advanced or metastatic gastric or GEJ cancer, refractory to standard cancer treatment.
- Patients should have a minimum of 1 measurable lesion on computed tomography (CT) or magnetic resonance imaging (MRI) as defined by RECIST version 1.1 within 4 weeks of the first dose of the study drug (Day 1). The lesion has to be a new lesion or progression of an existing lesion under the current therapy.
- Patients with brain metastases should have a minimum of 1 measurable lesion on MRI as defined by RANO-BM within 4 weeks of the first dose of the study drug (Day 1). The lesion has to be a new lesion or progression of an existing lesion under the current therapy.
- Any previous anti-HER2 treatment for advanced or metastatic disease is allowed. Patients with breast cancer should have had at least 2 previous systemic anticancer treatments for recurrent, locally advanced or metastatic cancer. Patients with gastric cancer or GEJ cancer should have had at least 1 previous anti-HER2 treatment.
- Life expectancy > 6 months.
-
Adequate organ function, determined by the following laboratory tests performed within 21 days before screening:
- Adequate kidney function with an estimated creatinine clearance of > 60 mL/min (Chronic Kidney Disease Epidemiology Collaboration formula).
- Adequate hepatic function defined as an alanine aminotransferase (ALT) and aspartate aminotransferase (AST) < 2.5 the upper limit of normal (ULN), or < 5 ULN in patients with liver metastases, and total bilirubin < 2 x ULN.
- Baseline left ventricular ejection fraction ≥ 50% as measured by echocardiography or multigated acquisition scan.
- Absence of any psychological, family, sociological, or geographical circumstance that could potentially represent an obstacle to compliance with the study protocol and the follow-up schedule, as determined by the Investigator. These circumstances will be discussed with the patient before enrollment in the study.
- Female patients of childbearing potential (ie, ovulating, premenopausal, and not surgically sterile) must have a negative serum pregnancy test within 7 days prior to administration of study drug. Patients and their partners of childbearing potential must be willing to use 2 methods of contraception, 1 of which must be a barrier method, for the duration of the study and should be maintained until 6 months after study drug administration. Medically acceptable barrier methods include condom with spermicide or diaphragm with spermicide. Medically acceptable non-barrier contraceptive methods include intrauterine devices or hormonal contraceptives (oral, implant, injection, ring, or patch).

| Critètes d'exclusion |
- Presence of frank leptomeningeal disease as a unique central nervous system feature or in association with brain parenchymal measurable lesion(s).
- Symptomatic brain metastases. Note: Patients with asymptomatic treated and untreated brain metastases are eligible.
-
Previous local therapy for brain metastases, such as neurosurgery, stereotactic radiotherapy, or whole brain radiotherapy, administered within 6 weeks prior to administration of CAM-H2.
Note: Previous therapy for brain metastases administered at least 6 weeks prior to CAM-H2 administration will be permitted.
-
For patients with brain metastases, any increase in corticosteroid dose during the week prior to enrollment.
Note: Corticosteroid treatment in a stable dose or decreasing dose for at least 4 weeks prior to enrollment is allowed.
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection requiring parenteral antibiotics or psychiatric illness/social situations that would limit compliance with study requirements.
- Uncontrolled thyroid disease, defined as free triiodothyronine (T3) and free thyroxine (T4) > 3 x ULN at screening.
- Uncontrolled diabetes defined as a fasting serum glucose > 2 x ULN or glycated hemoglobin levels > 8.5% at screening.
- Gastrointestinal (GI) tract disease resulting in an inability to take oral medication, malabsorption syndrome, a requirement for intravenous (IV) alimentation, prior surgical procedures affecting absorption, or uncontrolled inflammatory GI disease (eg, Crohn's, ulcerative colitis).
- Current active hepatic or biliary disease (exception of patients with Gilbert's syndrome, asymptomatic gallstones, liver metastases, or stable chronic liver disease per Investigator assessment).
- Ongoing peripheral neuropathy of Grade > 2 according to the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.
-
Severe and/or uncontrolled medical conditions or other conditions that could affect participation in the study such as:
- Symptomatic congestive heart failure of New York Heart Association Class III or IV.
- Unstable angina pectoris, symptomatic congestive heart failure, myocardial infarction within 6 months of start of study drug, serious uncontrolled cardiac arrhythmia, or any other clinically significant cardiac disease.
- Liver disease, including cirrhosis and severe hepatic impairment.
- Active (acute or chronic) or uncontrolled severe infections.
- Known history of HIV, hepatitis B, or active hepatitis C virus at screening.
- Prior investigational anticancer therapy within 4 weeks prior to CAM-H2 administration.
- Patients who have had a major surgery or significant traumatic injury within 4 weeks of start of study drug, who have not recovered from side effects of any major surgery (defined as requiring general anesthesia), or have a major surgery planned during the course of the study.
- Other malignancies within the past 3 years except for adequately treated carcinoma of cervix or basal or squamous cell carcinomas of the skin or stage I uterine cancer.
- Radiation therapy for metastatic disease foci outside the brain, administered within 3 weeks before study enrollment.
- Known hypersensitivity to any of the study drugs, including inactive ingredients, including iodine allergy.
- History of significant comorbidities that, in the Investigator's judgement, may interfere with study conduct, response assessment, or informed consent.
- Unable or unwilling to complete the study procedures.
- Patients that cannot be hospitalized in a radionuclide therapy room.
- Patients that are unable to comply with thyroid protective pre-medication.
- Patients in whom bladder catheterization cannot be performed, or in patients who are unwilling to be catheterized if necessary.
- Patients with contraindications for undergoing MRI or CT, including for receiving contrast agents.
- Patient is the Investigator or sub-Investigator, research assistant, pharmacist, study coordinator, or other staff or relative thereof, who is directly involved in the conduct of the study.
