Study of QRH-882260 Heptapeptide Application in the Colon

April 20, 2018 updated by: Danielle Kim Turgeon

Phase IB Study of QRH-882260 Heptapeptide Application in the Colon

A Phase 1B study of the efficacy of a topically-administered 7-amino acid peptide labeled with a near-infrared fluorophore Cy5 for detecting neoplastic areas of the colon is proposed. The study will test the efficacy of administering this agent (QRH-882260 Heptapeptide) to human subjects undergoing clinically-indicated colonoscopy for endoscopic resection of known colonic adenomas or for surveillance biopsies of known dysplasia in the setting of irritable bowel disease (IBD). Up to 120 evaluable subjects will be enrolled.

Subjects will be recruited around scheduled standard of care procedures. The endoscopists performing the procedures are all endoscopists credentialed at the University of Michigan to do these procedures. Urine for dipstick pregnancy testing (if applicable) will be collected before the procedure, along with medical information. Vital signs are routinely monitored throughout the clinical procedure and are available in the electronic medical record. The endoscopy will proceed per the University of Michigan Health System (UMHS) standard of care. The endoscopist performing the clinical procedure will evaluate the potential risk (if any) for the subject to continue with the procedure or study. Five mL of the reconstituted QRH-882260 Heptapeptide (~100 μM) will be sprayed onto the site of interest through a catheter in the endoscope. Five minutes after QRH-882260 Heptapeptide application, the unbound peptide will be washed off using the endogator irrigator and the residual liquid will be suctioned. Pictures with white-light and fluorescence will be taken with the scanning fiber based molecular imaging endoscopic probe inserted via the instrument channel of the standard endoscope before the QRH-882260 Heptapeptide application, immediately after application and then again after the QRH-882260 Heptapeptide will be washed off. The area of interest identified will be resected/biopsied per discretion of the endoscopist per clinical care. All specimens taken are for clinical care only (not research use) and will be sent for routine histology per UMHS standard of care.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

EXPERIMENTAL: Topical QRH Heptapeptide Administration
Drug: QRH-882260 Heptapeptide
topical spray; fluorescently-labeled peptide composed of a 7-amino acid sequence [Gln-Arg-His-Lys-Pro-Arg-Glu] attached via a 5 amino acid linker [Gly-Gly-Gly-Ser-Lys] to a near-infrared fluorophore, Cy5. The complete peptide sequence is written as: Gln-Arg-His-Lys-Pro-Arg-Glu-Gly-Gly-Gly-Ser-Lys(Cy5)-NH2, and is abbreviated as: QRHKPRE-GGGSK-(Cy5)-NH2.
Other Names:
  • QRH
Device: Scanning Fiber Endoscope
Endoscope used for providing the light via laser to image the area of interest in the colon after the QRH has been sprayed and rinsed.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Incidence of QRH-882260 Heptapeptide administration-related adverse events
Time Frame: 1 year
Continued monitoring of safety in subjects as measured by the number of Adverse Event (AE) assessments, severity (grade), and relationship to the study drug (any that could be related).
1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Efficacy of QRH-882260 Heptapeptide administration for detection of polypoid and non-polypoid colonic neoplasia
Time Frame: 1 year
The test product efficacy will be assessed by evaluating the fluorescence intensified measured from suspicious regions of colonic mucosa where the fluorescently-labeled peptide (QRH-882260) is administered. Measurement of peptide binding will be evaluated by the fluorescence intensity measured from the suspicious (target) region and normal tissues (background) to produce a target-to-background ratio.
1 year

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
