EU CTIS ID: 2024-515885-15-00
What this study is testing
To evaluate whole body distribution of 89Zr-Df-crefmirlimab in cancer patients prior to and during treatment with an anti-PD-1 antibody To evaluate pharmacokinetics (PK) of 89Zr-Df-crefmirlimab in patients prior to and during treatment with an anti-PD-1 antibody. To correlate tumour tracer uptake with immune cell CD8 expression as assessed by immunohistochemistry. To evaluate changes in tumour volumetry, mpMRI parameters and MRI based texture metrics during treatment with an anti-PD-1 antibody.

Who can take part
You may be able to join if
- Age ≥ 18 years at the time of signing informed consent.
- Willingness and ability to comply with all protocol required procedures.
- For female patients of childbearing potential and male patients with partners of childbearing potential, agreement (by patient and/or partner) to use a highly effective form(s) of contraception (i.e., one that results in a low failure rate (< 1% per year) when used consistently and correctly)).
- Patients with histologically confirmed diagnosis of locally advanced or metastatic solid cancer types who, according to the opinion of the principal investigator, based on available clinical data, may benefit from anti-PD1 antibody therapy.
- Disease progression following first-line therapy or any subsequent treatment line or no superior first line therapy available.
- At least 1 lesion that is accessible per investigator’s assessment and eligible for biopsy according to standard clinical care procedures.
You likely can't join if
- Treatment with any approved anti-cancer therapy, investigational agent or participation in another clinical trial with therapeutic intent within 28 days prior to 89Zr-Df-crefmirlimab infusion and nivolumab or cetrelimab treatment.
- Evidence of an active infection that requires systemic antibiotics within 2 weeks prior to 89Zr-Df-crefmirlimab infusion.
- Evidence of an active COVID 19 infection. Thisinfection has to be documented in the case record form. When at least 2 weeks recovered from COVID 19, this is not an exclusion criterion anymore.
- Any other diseases, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of 89Zr-Df-crefmirlimab, or that may affect the interpretation of the results or render the patient at high risk from complications.
- Altered mental status, or any psychiatric condition that would prohibit the understanding or rendering of informed consent.
- Sponsor employee/member of the clinical site study team and/or his or her immediate family

- At least 1 lesion that is accessible per investigator’s assessment and eligible for biopsy according to standard clinical care procedures.

Platelet count ≥75 x 109/L e. Serum creatinine ≤1.5 x upper limit of normal (ULN) or estimated glomerular filtration rate > 30 mL/min/1.73 m2. A 24-hour urine creatinine collection may substitute for the calculated creatinine clearance to meet eligibility criteria. f. Adequate hepatic function: i. Total bilirubin ≤1.5 x ULN (≤3 x ULN if liver tumour involvement); Patients with Gilbert’s syndrome do not need to meet total bilirubin requirements, provided their total bilirubin is unchanged from their baseline. Gilbert’s syndrome must be documented appropriately as past medical history. ii. Aspartate aminotransferase (AST) ≤2.5 x ULN (≤5 x ULN if liver tumour involvement) iii. Alanine aminotransferase (ALT) ≤2.5 x ULN (≤5 x ULN if liver tumour involvement) iv. Alkaline phosphatase (ALP) ≤2.5 x ULN (≤5 x ULN if liver or bone tumour involvement)
- Signed informed consent.

Patients with controlled infections must undergo periodic monitoring of HBV DNA. Patients must remain on anti-viral therapy for at least 6 months beyond the last dose of investigational study drug. • Patients who are HCV antibody positive who have controlled infection (undetectable HCV RNA by PCR either spontaneously or in response to a successful prior course of anti-HCV therapy) are permitted. • Patients positive for HCV antibody are eligible only if PCR is negative for HCV RNA.
