|Idiopathic Pulmonary Fibrosis||Biological: PRM-151 Other: Placebo||Phase 1|
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.

PRM-151 administered at escalating doses of 1, 5, and 10 mg/kg by 30 minute intravenous (IV) infusion days 1, 3, 5, 8 and 15.
Intravenous PRM-151 administered over 30 minutes on study days 1, 3, 5, 8, and 15 at doses of 1.0, 5.0, or 10.0 mg/kg.
Placebo Comparator: Placebo
0.9% saline administered by 30 minute IV infusion Days 1, 3, 5, 8, and 15.
Intravenous 0.9% normal saline administered over 30 minutes on study days 1, 3, 5, 8, and 15.

- FEV1 (Forced Expiratory Volume 1sec )(%) Change From Baseline [ Time Frame: Day 1 (Baseline) and Day 57 ]
- 6MWT (6 Minute Walk Test) Distance Walked Change From Baseline [ Time Frame: Screening (between Day -35 and Day 1) and Day 57 ]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 ]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.
