A Phase 1b Study of IV PRM151 in Patients With Idiopathic Pulmonary Fibrosis (IPF) (PRM151F-12GL)
The aims of the study are to assess safety, tolerability, the pharmacokinetic profile, and the pharmacodynamic profile of multiple doses of PRM-151 administered IV to IPF patients.

- Tmax [ Time Frame: Day 15 ] [ Designated as safety issue: No ]Time of Maximum observed concentration
- AUC48 [ Time Frame: Day 15 ] [ Designated as safety issue: No ]Area under the curve from 0 to 48 hrs post dose, with samples collected at 0.5, 0.75, 1, 1.5, 2, 3,4,6,8,12,16, 24 and 48 hours post Day 15 dose.
- Terminal Elimination Half Life [ Time Frame: Day 15 ] [ Designated as safety issue: No ]
- Total Body Clearance [ Time Frame: Day 15 ] [ Designated as safety issue: No ]
- Vss [ Time Frame: Day 15 ] [ Designated as safety issue: No ]Volume of Distribution at Steady State
- FVC (Forced Vital Capacity) Change From Baseline to Day 57 [ Time Frame: Change from Day 1 (Baseline) to Day 57 ] [ Designated as safety issue: No ]
- FVC (Forced Vital Capacity) % Predicted Change From Baseline [ Time Frame: Day 1 (Baseline) and Day 57 ] [ Designated as safety issue: No ]
- DLCO (%) (Diffusing Capacity of Carbon Monoxide) Change From Baseline [ Time Frame: Day 1 (Baseline) and Day 57 ] [ Designated as safety issue: No ]
- FEV1 (Forced Expiratory Volume 1sec )(%) Change From Baseline [ Time Frame: Day 1 (Baseline) and Day 57 ] [ Designated as safety issue: No ]
- 6MWT (6 Minute Walk Test) Distance Walked Change From Baseline [ Time Frame: Screening (between Day -35 and Day 1) and Day 57 ] [ Designated as safety issue: No ]Change from baseline (measured during screening period) in distance walked during a 6 minute walk test
- SGRQ (St. George's Respiratory Questionnaire) Total Score Change From Baseline [ Time Frame: Day 1 (Baseline) and Day 57 ] [ Designated as safety issue: No ]St. George's Respiratory Questionnaire Total Score. Scores range from 0 (no impairment) to 100 (maximum impairment). A decrease in score represents a decrease in disease related symptoms. The SGRQ is not validated for IPF.

Idiopathic pulmonary fibrosis (IPF) is a diffuse lung disease with a histological picture of usual interstitial pneumonia and a deteriorating clinical course. The prognosis is poor. Chronic alveolar inflammation with associated parenchymal remodeling is theorized to promote an ongoing abnormal fibrogenic repair response. Corticosteroids and immunomodulatory agents have not been shown to benefit IPF patients. Recently several published clinical studies have indicated a strong correlation between IPF severity and/or disease progression and the levels of specific plasma biomarker proteins related to epithelial cell health and extracellular matrix turnover.
PRM-151 is being developed for potential therapeutic uses to prevent, treat, and reduce fibrosis.
This study is the first intravenous multiple-dose study in humans, and will be conducted in patients with IPF. Patients will be randomized to receive either PRM-151 or placebo.
