Study Details

Study Description

Brief Summary

This is a randomized, placebo-controlled, double-blind, 6-month study followed by a 6 month open-label extension phase to evaluate the efficacy, safety, and tolerability of MN-001 in moderate to severe IPF patients. MN-001 750 mg or matching placebo will be orally administered twice daily over a 26 week period in subjects with a confirmed diagnosis of IPF per the ATS )American Thoracic Society) 2011 Guidelines. Approximately 15 subjects are planned to be enrolled. This study will consist of two treatment arms, MN-001 and matching placebo. Randomization will occur in a 2:1 ratio (MN-001: placebo). Eligible subjects will consist of males and females ranging in age from 21 to 80 years old, inclusive.

The study will consist of a Screening Phase (up to 3 months prior to Day1) followed by a 26 week double-blind Treatment Phase, a 26 week Open-Label Extension (OLE) phase and a Follow-up Visit (within 4 weeks after the last dose).

Arms and Interventions

Arm	Intervention/Treatment
Placebo Comparator: Double-Blind Treatment Subjects who complete all of the screening assessments and meet all inclusion/exclusion criteria will be started on MN-001 (tipelukast) 750 mg or matching placebo bid. Subjects will return to the clinic on Treatment Day 1 to receive their first dose of study medication. Subsequently, subjects will return to the clinic on a regular basis for 26 weeks. During the Treatment Phase, safety and efficacy parameters will be assessed and concomitant medications will be documented. The safety and tolerability of MN-001 will be evaluated by an Independent Safety Monitor during this phase.

Other: Open-Label Extension Upon completion of the Double-blind Treatment Phase, subjects who were taking placebo, will participate in the open-label extension (OLE) phase for an additional 6 months.

Outcome Measures

Primary Outcome Measures

Change from baseline of FVC (forced vital capacity) at 26 weeks [26 weeks]

Secondary Outcome Measures

The safety of MN-001 in subjects with IPF assessed by number of adverse events experienced by each participant [Subjects will return to the clinic at Months 1, 3, 6, and will be followed by telephone at Week 1 and Month 4]
Tolerability of MN-001 in subjects with IPF assessed by number of adverse events experienced by each participant [Subjects will return to the clinic at Months 1, 3, and 6 and will be followed by telephone at Week 1 and Month 4]
Rate of decline on disease activity based on the 6-minute walk test [The rate of decline on disease activity will be assessed at the 26-week visit]
Change from baseline on disease activity based on Modified Medical Research Council Dyspnea Score (MMRC) [The change from baseline on disease activity will be assessed at the 26-week visit]
Change from baseline on quality of life (QOL) measured by A Tool to Assess Quality of Life in Idiopathic Pulmonary Fibrosis (ATAQ-IPF) [The change from baseline on QOL will be assessed at the 26-week visit]
Frequency of worsening IPF based on 6-minute walk test score [Worsening of IPF will be assessed at Screening, Month 3, Month 6, Month 9 and Month 12.]
Frequency of worsening IPF based on Modified Medical Research Council Dyspnea Score (MMRC) [Frequency of worsening IPF will be assessed at Screening, Month 3, Month 6, Month 9 and Month 12.]
Time to first worsening IPF based on MMRC score [Time to first worsening IPF will be assessed at Screening, Month 3, Month 6, Month 9 and Month 12.]
Time to first worsening IPF based on 6MWT score [Time to first worsening IPF will be assessed at Screening, Month 3, Month 6, Month 9 and Month 12.]

Note: Active medical conditions that are minor or well-controlled are not exclusionary if, in the judgment of the Investigator, they do not affect risk to the subject or the study results. In cases in which the impact of the condition upon risk to the subject or study results is unclear, the Medical Monitor should be consulted.
