Overview
The purpose of this study is to determine the safety and feasibility of VGT-309 for the visualization of colorectal tumors in real-time using near-infrared (NIR) fluorescence endoscopy. In addition, signatures of 50+ biomarkers will be evaluated in biopsies using CODEX multi-plexing.
Eligibility
Inclusion Criteria:
- 1. Adult patients with histologically confirmed distal colorectal adenocarcinoma of
any stage. 2. Be willing and able to sign the informed consent and comply with study procedures. 3. Are scheduled to undergo a SOC colonoscopy for restaging following
radiochemotherapy or are scheduled to receive a SOC colonoscopy in the OR prior to
resection 4. Have acceptable kidney and liver functions at study entry as evidenced
- by
-
- ALT/AST < 1.5 times the upper limit of normal, b. Creatinine clearance (according to Cockcroft-Gault Equation) > 50 mL/min c. Total bilirubin < 1.5 times the upper limit of normal 5. Have an ECOG score of 0-2. 6. Be at least 18 years of age. 7. Female participants must be of non-childbearing potential, or, if of childbearing potential be non-pregnant or lactating and agree to use highly effective contraception from screening through 30 days after probe infusion 8. Male participants, if not surgically sterilized, and if engaging in sexual intercourse with a female partner of childbearing potential, must be willing to use highly effective contraception from screening through 30 days post-dose and agree not to donate semen during this waiting period.
- Highly effective contraception involves the use of a condom for the male, plus one
of the following for the female:
- Oral, injectable, implantable, intravaginal, or transdermal hormonal contraceptives, or
- Intrauterine device or intrauterine hormone-releasing system. NOTE: Participants
who abstain from heterosexual intercourse as their usual and preferred lifestyle,
will not be required to use contraception as described above. They are required
to maintain abstinence from screening through Day 30, AND Participants in a same
sex relationship, must use a barrier form of contraception (e.g., condom,
diaphragm) to protect against the transfer of the study drug in any bodily
fluids.
Exclusion Criteria:
- 1. Pregnant or breastfeeding females 2. They have a known allergy or reaction to ICG,
other radiographic contrast agents, or any component of VGT-309.
3. Have congenital long QT syndrome or QTcF > 450ms (males) or >470ms (females) by history or at Screening ECG. 4. They are prisoners, institutionalized individuals, or are unable to consent for themselves. 5. Have any other comorbidity or habit that the Investigator believes will interfere with their ability to comply with and complete the study.
