Collagen-targeted Positron Emission Tomography (PET) Imaging for Assessment of EGCG Effect

Study Purpose

The primary purpose of this substudy is to determine if collagen-targeted PET using the type 1 collagen-targeted PET probe, Gallium-68 (68Ga)-labeled collagen binding probe 8 (CBP8) can inform as to drug effect of EGCG and assist in dose selection.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	40 Years - 85 Years
Gender	All

More Inclusion & Exclusion Criteria

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT06265532
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	Phase 1
Lead Sponsor The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.	Hal Chapman

Conditions The disease, disorder, syndrome, illness, or injury that is being studied.	Idiopathic Pulmonary Fibrosis

Additional Details

This is an optional sub-study of the phase I study: "Dose ranging study of oral epigallocatechin-3-gallate (EGCG) given daily for 12 weeks to patients with Idiopathic Pulmonary Fibrosis (IPF) evaluating safety, pharmacokinetic (PK) interactions with standard of care drugs, and biomarkers of drug effect." Up to twenty-two participants participating in the aforementioned study will be enrolled into this sub-study. This substudy will be conducted at a select number of sites with capabilities for performing [68Ga]CBP8 PET. Eligible participants who consent to the substudy will undergo [68Ga]CBP8 PET-CT or [68Ga]CBP8 PET-MRI at two time points. Participants will undergo 68Ga-CBP8 PET within 7 days prior to randomization and then again within 7 days prior to day 84 of the phase I study. The hypothesis is that [68Ga]CBP8 PET will detect decreased collagen deposition in individuals treated with EGCG compared to placebo.

Arms & Interventions

Arms

Active Comparator: EGCG 300 mg

Patients enrolled in this group will be given oral capsule EGCG 300 mg daily with doctor provided anti-fibrotic for 12 weeks.

Placebo Comparator: Placebo for EGCG 300 mg

Patients enrolled in this group will be given oral capsule Placebo daily for 12 weeks with doctor provided anti-fibrotic. The number of placebo capsules will be equal to that of 300 mg EGCG.

Active Comparator: EGCG 600 mg

Patients enrolled in this group will be given oral capsule EGCG 600 mg daily with doctor provided anti-fibrotic for 12 weeks.

Placebo Comparator: Placebo for EGCG 600 mg

Patients enrolled in this group will be given oral capsule Placebo daily for 12 weeks with doctor provided anti-fibrotic. The number of placebo capsules will be equal to that of 600 mg EGCG.
