Clinical Trial Summary

Phase I study to evaluate the human safety and tolerability, biodistribution and dosimetry of 68GaNOTA-Anti-MMR-VHH2

Phase IIa study to evaluate tumour uptake of 68Ga-NOTA-anti-MMR-VHH2 in patients with breast cancer or melanoma. To correlate uptake of 68Ga-NOTA-anti-MMR-VHH2 in cancer lesions to immunohistological MMR staining after resection or biopsy of the same lesion.

Eligibility

PART I:

Inclusion Criteria:

Patients will only be included in the study if they meet all of the following criteria:

• Patients who have given informed consent

• Patients at least 18 years old

• Patients with local, locally advanced or metastatic disease of a malignant solid tumor. In order to minimize partial volume effect the diameter of at least 1 tumor lesion should be = 10 mm in short axis for invaded adenopathies and = 10 mm in long axis for all other types of lesions.

Exclusion Criteria:

Patients will not be included in the study if one of the following criteria applies:

• Eastern Cooperative Oncology Group (ECOG) performance status 3 or higher

• Pregnant patients

• Breast feeding patients

• Patients with abnormal liver (Bilirubin =1.5 x ULN, ALT (SGPT) =3 x ULN) or kidney function (Serum creatinine clearance =50 ml/min as calculated with Cockcroft-Gault formula)

• Patients with recent (< 1 week) gastrointestinal disorders (CTCAE v4.0 grade 3 or 4) with diarrhea as major symptom

• Patients with any serious active infection

• Patients who have any other life-threatening illness or organ system dysfunction, which in the opinion of the investigator would either compromise patient safety or interfere with the evaluation of the safety of the test radiopharmaceutical

• Patients who cannot communicate reliably with the investigator

• Patients who are unlikely to cooperate with the requirements of the study

• Patients who are unwilling and/or unable to give informed consent

• Patients at increased risk of death from a pre-existing concurrent illness

• Patients who participated already in this study

PART II:

Inclusion Criteria:

Patients will only be included in the study if they meet all of the following criteria:

• Patients who have given informed consent

• Patients at least 18 years old

• Patients diagnosed with a local, locally advanced or metastatic disease, with any of the following cancer types :

• Triple-negative breast carcinoma,

• Hormone-receptor negative (HR-), HER2+ breast carcinoma, with HER2-expression defined as HER2+ on ISH or 3+ on IHC, as determined by local assessment on any of the available cancer tissues

• Melanoma

• Patients who have had a biopsy of at least one lesion or who are planned to undergo standard-of-care resection or biopsy of at least one lesion, in order to minimize partial volume effect, the diameter of that lesion should be = 10 mm in short axis for invaded adenopathies and = 10 mm in long axis for all other types of lesions.

Exclusion Criteria:

Patients will not be included in the study if one of the following criteria applies:

• Eastern Cooperative Oncology Group (ECOG) performance status 3 or higher

• Pregnant patients

• Breast feeding patients

• Patients with recent (< 1 week) gastrointestinal disorders (CTCAE v4.0 grade 3 or 4) with diarrhea as major symptom

• Patients with any serious active infection

• Patients who have any other life-threatening illness or organ system dysfunction, which in the opinion of the investigator would either compromise patient safety or interfere with the evaluation of the safety of the test radiopharmaceutical

• Patients who cannot communicate reliably with the investigator

• Patients who are unlikely to cooperate with the requirements of the study

• Patients who are unwilling and/or unable to give informed consent

• Patients at increased risk of death from a pre-existing concurrent illness

• Patients who participated already in this study

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Tolerability and safety of 68GaNOTA-Anti-MMR-VHH2: reported as type, frequency and severity (graded according to the CTCAEv5) (Part I).	Assessed using physical examination and blood sampling for hematology and clinical chemistry.	Before injection up until 6 hrs after injection
Primary	Human biodistribution using blood sampling and PET/CT imaging: reported as relative uptake values per organ at 10, 90 and 150 minutes per individual subject and as a mean over all subjects (Part I).	Measured in standard uptake values in PET/CT imaging and expressed in relation to the injected activity.	Immediately after injection up to 3 hrs after injection
Primary	Human dosimetry using PET/CT imaging data: radiation dose to individual organs and the equivalent dose for the whole body of each subject and as a mean over all subjects (Part I).	Dosimetry will be calculated using the OLINDA software.	10 min up to 3 hrs after injection
Primary	Tumor targeting potential using PET/CT and correlation to immunohistological MMR staining after resection: assessed using correlation coefficient (Part II).	PET/CT and immunohistochemistry will be assessed using a semi-quantitative scale.	Resection of lesion up to 14 days after PET/CT
