Study Endpoints

Primary Endpoints

Percentage of Participants Disease-Free at 2 Years
Up to 2 years after study start

A survival analysis will be conducted on disease-free survival (DFS). The survivor functions for DFS will be estimated with Kaplan and Meier method and plotted. The logrank test will be used to test the difference in DFS of (a) both arms in aggregate with the survivor function on our prior R01 trial and (b) between the two study arms.

Secondary Endpoints

Decision to Offer Radiotherapy
Baseline (pre-PET treatment) and final treatment decision (post-PET), up to 4 weeks
Decision to Treat Pelvic Nodes
Baseline (pre-PET treatment) and final treatment decision (post-PET), up to 4 weeks
Decision to Boost Between the Initial and Final Treatment Decisions
Baseline (pre-PET treatment) and final treatment decision (post-PET), up to 4 weeks

Frequently asked questions about Fluciclovine F18

What is Fluciclovine F18 used for in prostate adenocarcinoma?

Fluciclovine F18 is an investigational small molecule being studied for use in prostate adenocarcinoma. It is a diagnostic imaging agent that is being evaluated in a Phase 2 clinical trial to enhance prostate cancer outcomes. The drug is not yet approved and remains in clinical development.

What does Fluciclovine F18 target?

Fluciclovine F18 is a synthetic amino acid that is taken up by prostate cancer cells. It is used in positron emission tomography (PET) imaging to visualize prostate cancer. The drug targets amino acid transporters that are overexpressed in prostate cancer cells, allowing for detection of the disease.

Who is developing Fluciclovine F18?

Fluciclovine F18 is being developed by Telix Pharmaceuticals Limited, a biopharmaceutical company listed on the Australian Securities Exchange under the ticker TLX. The company is conducting clinical trials to evaluate the drug's safety and efficacy in patients with prostate adenocarcinoma.

What phase is Fluciclovine F18 in?

Fluciclovine F18 is currently in Phase 2 clinical development. It is an investigational drug and has not received FDA approval. The ongoing Phase 2 trial is active but not recruiting participants, and is designed to assess the drug's ability to enhance prostate cancer outcomes.

What clinical trials is Fluciclovine F18 in?

Fluciclovine F18 is being evaluated in a Phase 2 clinical trial with the identifier NCT03762759. The trial, titled 'Fluciclovine F18 or Ga68-PSMA PET/CT to Enhance Prostate Cancer Outcomes,' is enrolling 140 male patients aged 18 years and older with prostate adenocarcinoma in the United States. The study is active but not recruiting.

Is Fluciclovine F18 the same as Ga68-PSMA?

Fluciclovine F18 is not the same as Ga68-PSMA. Fluciclovine F18 is a synthetic amino acid used for PET imaging, while Ga68-PSMA is a different imaging agent that targets prostate-specific membrane antigen. The two agents are being compared in a clinical trial to determine which is more effective for enhancing prostate cancer outcomes.
