Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - 68Ga-FAPi-46
Treatment: Surgery - PET/CT imaging

Experimental: 68Ga-FAPI-PET/CT - Patients receive 68Ga-FAPI IV then undergo PET/CT.


Treatment: Drugs: 68Ga-FAPi-46
FAPI-46 is a small molecular radiopharmaceutical that binds to the fibroblast activated protein on cancer associated fibroblasts. Gallium-68 (68Ga) is a positron-emitting isotope with a half-life of 68 minutes.

Treatment: Surgery: PET/CT imaging
PET with the investigational tracer 68Ga-FAPI-46 with accompanying low-dose CT for anatomical localisation

Eligibility
Key inclusion criteria
1. Participant has provided written informed consent

2. Participants aged 18 years or over at screening

3. Diagnosed with CUP based on a diagnostic work-up, including, but not limited to; a
detailed clinical assessment; a CT scan of the chest/abdomen, and pelvis; pathological
review of tumour tissue; and other appropriate tests as per the Cancer Council Optimal
Care Pathway guidelines

4. Has not commenced current line of systemic treatment

5. Eastern Cooperative Oncology Group performance status 0 - 2

6. Life expectancy greater than 3 months

7. Adequate hematologic and organ function to commence systemic treatment, defined by the
following laboratory results:

1. Haemoglobin = 90g/L

2. Absolute neutrophil count =1.5 x 109/L

3. Platelet count = 100 x 109/L

4. Creatinine clearance = 30mL/min

5. Serum bilirubin = 1.5 x upper limit of normal (ULN); patients with known
Gilbert's disease may have a bilirubin = 3.0 x ULN

6. Aspartate transaminase (AST) or alanine transaminase (ALT) =2 x ULN (or = 5 x ULN
in the presence of liver metastases)

8. Willing and able to comply with all study requirements, including all treatment and
required assessments including follow-up procedures, in the investigator's judgment
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. Uncontrolled medical or psychological conditions that may prevent commencement of
systemic treatment.

2. Major surgical procedure within 6 weeks prior to study registration or active
infection requiring systemic treatment

a. Placement of vascular access devices is not considered major surgery.

3. Concurrent illness, including severe infection that may jeopardise the ability of the
participant to undergo procedures outlined in this protocol with reasonable safety

4. Prior cancer diagnosis with the exception of:

1. Malignancy treated with curative intent and with no known active disease = 3years
and of low potential risk of recurrence

2. Adequately treated basal cell or squamous cell skin carcinoma or non-invasive
melanoma

3. Adequately treated non-muscle invasive bladder cancer (Tis, Ta and low grade T1
tumours)

4. Adequately treated carcinoma in situ without evidence of disease

5. Cancer subjects with incidental histologic findings of prostate cancer that, in
the opinion of the Investigator, is not deemed to require active therapy (e.g.,
incidental prostate cancer identified following cystoprostatectomy that is
tumour/node/metastasis stage = pT2N0)

5. Greater than one prior line of systemic treatment

6. Known allergy or reaction to 18F or 68Ga tracer

Summary
Brief summary
This is a prospective single arm cohort study designed to evaluate the diagnostic ability of
68Ga-FAPI-PET/CT scan in determining likely tissue of origin in Cancer of Unknown Primary
(CUP) patients not identified by standard of care. Patients with CUP will be either treatment
naïve or starting second-line treatment.
