New York, New York
This is a single arm phase II study of image-guided pencil beam scanning proton SBRT (40Gy RBE in 5 fractions delivered every other day) for patients with low- and intermediate-risk prostate cancer. The primary aim is to assess GU/GI toxicity of proton SBRT and compare this to historic outcomes associated with photon-based prostate SBRT. The primary endpoint is 2-year grade 3+ GU/GI toxicity free rate by CTCAE v5.0, which is expected to be ≥95%. Toxicity will be evaluated by the treating radiation oncologist at least once during SBRT, then following SBRT at 1, 3, 6, 12, 18, and 24 months. The treatment will be considered safe if grade 3 or higher GU/GI toxicity free rate at 2 years is \>85% (95% rate expected with a 10% non-inferiority margin). The accrual goal is 61 patients over 3 years. To ensure that unexpected significant toxicity is identified, all grade 3 or higher toxicities will be reported to the study PI and the trial will stop accruing if at any point 4 or more patients experience a grade 3 or higher toxicity after completing SBRT. This is felt to be conservative given the vast experience with photon SBRT at this dose with an expected G3+ toxicity of \~5%.
Secondary objectives are to examine patient-reported urinary, gastrointestinal, sexual, and financial outcomes using IPSS, EPIC-26, and COST questionnaires at the same follow-up timepoints as above. Baseline measures of these domains will be obtained prior to treatment as well. Clinical outcomes will also be evaluated with PSA measured at each follow-up, as well as prostate MRI and biopsies at 2 years. Patients will be followed for at least 2 years to determine rates of PSA relapse, salvage treatment, development of metastases, death from prostate cancer, and overall survival. A dosimetric comparison will be performed where each patient will be planned for proton and photon SBRT to determine possible advantages of proton SBRT.

We started Power when my dad was diagnosed with multiple myeloma, and I struggled to help him access the latest immunotherapy. Hopefully Power makes it simpler for you to explore promising new treatments, during what is probably a difficult time.

Frequently Asked Questions
How much do clinical trials pay?
Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.How do clinical trials work?
After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length is 12 months.How do I participate in a study as a "healthy volunteer"?
Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.What does the "phase" of a clinical trial mean?
The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.Do I need to be insured to participate in a medical study ?
Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.What are the newest clinical trials ?
Most recently, we added Proton SBRT for Prostate Cancer to the Power online platform.Popular Searches
