Study Details
Study Description
Brief Summary
The goal of this study is to investigate the ability of [68Ga]CBP8 to detect collagen deposition in early interstitial lung disease.

| Phase 2 |
Detailed Description
[68Ga]CBP8, is a PET imaging probe which selectively binds collagen type I. Collagen deposition is a pivotal event in the development of pulmonary fibrosis. [68Ga]CBP8 binds collagen with high affinity and has excellent pharmacological and pharmacokinetic profiles. [68Ga]CBP8 was shown in a mouse model to be effective for detecting lung fibrosis and response to treatment. In addition, [68Ga]CBP8 can detect increased collagen in the lungs of patients with idiopathic pulmonary fibrosis.
The goals of this study are:
-
To determine whether collagen deposition as assessed by [68Ga]CBP8-PET MRI can detect increased collagen deposition in early interstitial lung disease and
-
if the degree of [68Ga]CBP8 uptake predicts subsequent disease progression.

Outcome Measures
Primary Outcome Measures
- Degree of uptake of [68Ga]CBP8 [24 months]
The degree of uptake of [68Ga]CBP8 in the lungs will be compared between groups and associations with disease severity and progression will be determined.
Secondary Outcome Measures
- Rate of MRI contrast clearance, Kwashout, in the lungs [24 months]
Kwashout rates will be compared between groups and associations with disease severity, progression, and degree of uptake of [68Ga]CBP8 will be determined.
- Rate of MRI contrast arrival, Kwashin, in the lungs [24 months]
Kwashin rates will be compared between groups and associations with disease severity, progression, and degree of uptake of [68Ga]CBP8 will be determined.
- Peak enhancement of MRI contrast in the lungs [24 months]
Peak enhancement will be compared between groups and associations with disease severity, progression, and degree of uptake of [68Ga]CBP8 will be determined.
