NCT06265532

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Change in collagen probe uptake over the entire lungs

    Changes in lung collagen uptake will be measured using the PET probe \[68\]Ga-CBP8. Measurements will be made over the entire lungs using standardized uptake values.

    From baseline to 12 weeks

Other Outcomes (5)

  • Change in peak enhancement over the entire lungs

    From baseline to 12 weeks

  • Change in the rate of contrast washin over the entire lungs

    From baseline to 12 weeks

  • Change in the area under the curve at 60 seconds over the entire lungs

    From baseline to 12 weeks

  • +2 more other outcomes

Study Arms (4)

EGCG 300 mg

ACTIVE COMPARATOR

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

Drug: EGCG 600 mg

Placebo for EGCG 600 mg

PLACEBO COMPARATOR

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.

Drug: Placebo for EGCG 600 mg

Interventions

Participants will be administered EGCG as part 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, PK interactions with standard of care drugs, and biomarkers of drug effect."

Also known as: Dietary Supplement: EGCG Capsules with EGCG (at least 94% purity). 300 mg EGCG (2 capsules) taken orally daily for 12 weeks.
