Primary Outcome Measures:
  • Number of subjects with abnormal lab values [ Time Frame: 48 hours ]
    review of laboratory values for abnormalities after intervention with KSP-910638G

Estimated Enrollment: 25
Anticipated Study Start Date: June 1, 2017
Estimated Study Completion Date: December 1, 2017
Estimated Primary Completion Date: December 1, 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: KSP-910638G
The first three subjects will receive lyophilized powder reconstituted with 5 mL of 0.9% NaCl, 0.4 mg of KSP-910638G total. For the first three subjects, 3.34 mL of KSP-910638G will be discarded. The 1.66 mL of KSP-910638G remaining in the syringe will be administered by squirting it into the mouth of the subject. Following a safety review of these three subjects, the remaining 22 subjects will receive the full 1.2 mg dose of KSP-910638G reconstituted in 5 mL 0.9% NaCl. These 22 subjects will receive all 5 mL of the peptide solution in a syringe for administration. The agent will not be reconstituted until the subject is ready to squirt the peptide into his or her mouth via syringe. They will be asked to wait 5 minutes and then drink at least 4-8 oz of tap water.
Drug: KSP-910638G
The investigational agent to be used in this study is KSP heptapeptide, which is a fluorescently-labeled peptide composed of a 7-amino acid sequence attached via a 5 amino acid linker known as Cy5.

Detailed Description:

This is a Phase IA study of the safety of an orally administered KSP-910638G heptapeptide for detection of neoplastic tissues in multiple areas of the gastrointestinal tract in humans. The investigators intend to enroll 25 evaluable subjects. The investigators expect to be able to enroll about 1-2 subjects per week, so the study should take about 4-6 months to complete.

Interested, healthy subjects ages 25-100 who respond to recruitment advertising on and appear to be eligible based responses to inclusion/exclusion criteria questions will be scheduled for a study visit at MCRU. At the study visit, the subjects will review and sign the informed consent and eligibility will be confirmed. If eligible, subjects will provide a blood sample for clinical labs and a urine sample for urinalysis. A negative urine pregnancy test for women of child-bearing potential is required to be eligible. Eligible subjects will consume the reconstituted KSP-910638G. After 5 minutes, subjects will drink a minimum 4-8 ounces of tap water and vital signs will be taken. Subjects will remain in MCRU for observation for 30 minutes. Vital signs will be recorded after 30 minutes. Subjects are required to return to MCRU to have a repeat blood draw for clinical labs and urinalysis within 24 to 48 hours after KSP-910638G ingestion. The study team will conduct a verbal assessment for toxicity at this visit.
