SHAPER Trial Summary
This trial is studying losartan and hypofractionated radiation therapy to see if they are effective in treating pancreatic cancer.
Who is the study for?
This trial is for patients with pancreatic cancer that's borderline resectable or locally advanced and unresectable. They must have had at least one round of specific chemotherapy, be within certain blood and organ function parameters, not pregnant, willing to use effective contraception, and able to consent. Exclusions include those on high-dose losartan, other trials, prior malignancies affecting safety assessments, previous radiation or surgery for pancreatic cancer, uncontrolled ulcers or chronic coughs among others.Check my eligibility
What is being tested?
The SHAPER trial is testing the combination of losartan (a drug that may improve blood flow) with hypofractionated radiation therapy (which delivers higher doses in a shorter period), following chemotherapy. The goal is to see if this combo is more effective than just radiation alone in treating pancreatic cancer by killing more tumor cells with fewer side effects.See study design
What are the potential side effects?
Potential side effects from losartan might include low blood pressure symptoms like dizziness or fainting. Radiation therapy can cause skin irritation at the treatment site, fatigue, nausea and potential damage to nearby organs depending on its location.

Experimental Treatment
Group I: Treatment (losartan, hypofractionated radiation therapy)Experimental Treatment5 Interventions
Beginning on day 1, patients receive losartan potassium PO QD. Beginning day 14, patients also undergo hypofractionated radiation therapy over 15 fractions 5 days a week for up to 3 weeks. Patients continue to receive losartan potassium PO QD during radiation therapy and for 28 days after completion of radiation therapy. Patients may begin additional anti-cancer therapy per investigator discretion after the last dose of HRT. Losartan can be given concurrently with additional therapy and Losartan dosing can continue until 28 days after last dose of HRT, regardless of when additional therapy is started.

Are there any current opportunities to participate in the clinical trial?
"Per data provided by clinicaltrials.gov, this research project is currently enlisting test subjects. The study was initially posted on the 8th of August 2019 and most recently edited on May 3rd 2022."
Answered by AI
What conditions may be rectified with Hypofractionated Radiation Therapy?
"Hypofractionated Radiation Therapy is commonly used to manage diabetic nephropathy and has been found useful in treating left ventricular hypertrophy, proteinuria, and hypertensive disease."
Answered by AI
What is the maximum capacity of volunteers for this research project?
"Affirmative. As evidenced on clinicaltrials.gov, this medical trial is actively seeking participants as of May 3rd 2022 since its original posting date of August 8th 2019. There are 20 patients required for the study to be conducted at one site location."
Answered by AI
Is Hypofractionated Radiation Therapy a dangerous treatment for patients?
"Hypofractionated Radiation Therapy is a relatively new intervention, so its safety rating was set as 1 due to the limited clinical data supporting efficacy and safety."
Answered by AI
Has Hypofractionated Radiation Therapy been subjected to testing in other experiments?
"At the moment, there are 30 ongoing trials examining Hypofractionated Radiation Therapy with 2 of these reaching Phase 3. While San Francisco has the majority of studies involving this therapy, 533 other locations across the world feature clinical trial related to it."
