The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Eligibility
Key inclusion criteria
INCLUSION CRITERIA:

1. =18 years of age at the time of signing the informed consent.
2. Histologically confirmed diagnosis of soft tissue sarcoma (STS)
3. At least one mass of > 2 cm in largest diameter seen on standard of care imaging (CT, MRI and/or FDG-PET).
4. For Part A: Participants must have tumour PDGFRa expression confirmed by IHC. Participants must have consented to provide archived FFPE tumour tissue or be subject to a biopsy of the target tumour (if archived tissue is unavailable).

For Parts B and C: all participants will be included regardless of their PDGFRa expression status on archival tissue/biopsy (unless otherwise specified). Participants must have consented to provide available archived FFPE tumour tissue.
5. Adequate haematologic function as defined by an absolute neutrophil count (ANC) = 1500/ µL, haemoglobin = 9.0 g/dL, and a platelet count of 100,000/µL obtained.
6. Adequate hepatic function as defined by a total bilirubin = 1.5 mg/dL, and aspartate transaminase (AST) and alanine transaminase (ALT) = 3.0 times the upper limit of normal (ULN).
7. Adequate renal function as defined by serum creatinine = 1.5 × the institutional ULN. If creatinine is above the ULN, the participant's creatinine clearance is = 45 mL/min.
8. Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2.
9. Life expectancy of at least 6 months.
10. Female participants of childbearing potential must have negative pregnancy tests at screening, as well as confirmation of negative pregnancy test result within 24 hours prior to receiving 89Zr-TLX300-CDx. Female participants of childbearing potential or male participants with female partners of childbearing potential must:

1. be willing to practice full and true sexual abstinence; or
2. be surgically/permanently sterile or with a history of hysterectomy for women; or
3. be willing to practice highly effective contraception by using: a non-oral, injected or implanted non-oestrogen progesterone based hormonal method, male condom, vaginal diaphragm, cervical cap, intrauterine device, for 3 months after the administration of 89Zr-TLX300-CDx.
11. Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol.

EXCLUSION CRITERIA:

1. Known or suspected hypersensitivity to olaratumab, DFOsq, 89Zr or any of the excipients.
2. IgE antibodies against galactose-a-1,3-galactose (a-Gal) above the upper limit of normal, > 0.7 kU/L.
3. Exposure to any experimental diagnostic or therapeutic drug within 30 days from the date of planned administration of 89Zr-TLX300-CDx.
4. Surgery = 2 weeks prior to the administration of 89Zr-TLX300-CDx or significant ongoing complications of surgery. Biopsy = 2 weeks prior to the administration of 89Zr-TLX300-CDx is allowed.
5. Exposure to any radiopharmaceutical within 10 half-lives prior to the administration of 89Zr-TLX300-CDx.
6. Ongoing toxicity Grade 2 or higher from previous standard or investigational therapies (Common Terminology Criteria for Adverse Events [CTCAE] version 5).
7. Planned to commence systemic antineoplastic therapies, immunotherapy, targeted therapy, radiotherapy and/or surgery for the period between administration of 89Zr-TLX300-CDx and last imaging timepoint.
8. Serious non-malignant disease (e.g., psychiatric, infectious, autoimmune or metabolic) or any disease that may interfere with the objectives of the study or with the safety or compliance of the participant, as judged by the Investigator.
9. Pregnant or lactating women.
10. Participants unable to declare meaningful informed consent on their own (e.g., with legal guardian for mental disorders) or unable to tolerate the study procedures.
