Trial of eRapa to Prevent Progression in Familial Adenomatous Polyposis Patients Under Active Surveillance
Phase IIA Trial of Encapsulated Rapamycin (eRapa) to Prevent Progression in Familial Adenomatous Polyposis Patients Under Active Surveillance
Study Overview

Intervention / Treatment
Detailed Description
Patients with FAP who are undergoing endoscopic surveillance will be given eRapa at one of three escalating doses/ schedules (0.5mg every other day, 0.5mg daily every other week, or 0.5mg daily) for 12 months with the aim of reducing polyp burden. Patients will serve as their own controls. Patients will be assessed with surveillance endoscopy at baseline, 6 months, and 12 months for change in polyp burden. Correlation between immune markers and clinical outcomes will be explored.
This is a Phase IIa trial which will enroll at approximately 6-8 sites within the United States that have specialty expertise in FAP treatment and surveillance. The trial is anticipated to last approximately 24 months for treatment and follow up.
The trial will enroll 30 patients with the genetic or clinical diagnosis of FAP. The clinical diagnosis includes individuals with 100 or more cumulative tubular adenomas throughout the colorectum. Patients must be undergoing surveillance for known FAP and can include those with intact colons as well as those who have undergone surgical therapy. For those patients who have undergone partial or total colectomy, they must have documented residual polyps in their rectum for which they are receiving active surveillance.

- Serum creatinine or measured/ calculated creatinine clearance (or glomerular filtration rate [GFR]) > 1.5 x ULN OR < 30mL/min for participants with creatine levels > 1.5 x institutional ULN. Bilirubin ≥ 1.5 x ULN unless conjugated bilirubin ≤ ULN; alkaline phosphatase > 5 x ULN; ALT/AST > 2 x ULN.
- INR or PT or aPTT > 1.5 x institutional ULN unless the patient is receiving anticoagulant therapy as long as the PT or aPTT is within therapeutic range of intended use of anticoagulants.
- Proteinuria > 1+ on urinalysis or > 1g/24h on 24h urine.
- History of interstitial lung disease or non-infectious pneumonitis.
- Immunosuppressed state (e.g., HIV, use of chronic steroids), active, uncontrolled infection.
- On agents known to alter rapamycin metabolism significantly.
- Concurrent involvement in other clinical trials specifically evaluating chemoprevention in FAP.
- Patients with a colonic polyp burden too numerous to count.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Frequency and severity of adverse events associated with low dose eRapa in FAP patients
Time Frame: All adverse events with start dates occurring any time after informed consent is obtained until 7 days (for non-serious adverse events) or 30 days (for serious adverse events) after the last day of study participation will be recorded.
|
Safety and tolerability of eRapa as determined by graded toxicity assessed throughout the trial per CTCAE v5.0.
|
All adverse events with start dates occurring any time after informed consent is obtained until 7 days (for non-serious adverse events) or 30 days (for serious adverse events) after the last day of study participation will be recorded.
|
Determine the Recommended Phase 2 Dose (RP2D)
Time Frame: After informed consent is obtained up to 30 days after the last day of study participation.
|
The Recommended Phase 2 Dose (RP2D) will be determined by examining and analyzing safety/ adverse events as reflected by Outcome 1, dose delays, dose reductions, withdrawal of treatment secondary to low-grade toxicities, and serum pharmacokinetic monitoring.
|
After informed consent is obtained up to 30 days after the last day of study participation.
|
Efficacy of eRapa in delaying polyp progression in patients with FAP as measured by change in polyp burden over time.
Time Frame: Time for each patient is baseline to 6 months.
|
Percentage change from baseline in colorectal polyp burden as measure by endoscopy at 6 months.
|
