Brief Summary:
This study will evaulate the long-term safety, efficacy and pharmacokinetics (PK) of recombinant human pentraxin-2 (rhPTX-2; PRM-151) zinpentraxin alfa, administered by intravenous (IV) infusion to participants with idiopathic pulmonary fibrosis (IPF).

Condition or disease Intervention/treatment Phase
Idiopathic Pulmonary Fibrosis Drug: PRM-151 (Zinpentraxin Alfa) Phase 3

Detailed Description:
This study is being conducted for the treatment of eligible participants who have taken part in Study PRM-151-202 and received the open-label study drug or completed the Phase III Study WA42293 with PRM-151. Participants who have discontinued treatment from or have completed Study WA42293 and do not want to receive PRM-151 in this study, will be invited to enroll in survival follow-up.

Arms and Interventions
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
Experimental: PRM-151

Corhort A: Participants entering, following participation in study PRM-151-202.

Cohort B: Participants entering, following participation in study WA42293.

 Drug: PRM-151 (Zinpentraxin Alfa)

Cohort A: Participants will receive three loading doses of open-label PRM-151 on days 1, 3, and 5, then one infusion every 4 weeks (Q4W). 10 mg/kg of PRM 151 will be administered by intravenous (IV) infusion over 60 minutes on days 1, 3, and 5, then one infusion every 4 weeks.

Cohort B: Participants previously randomized to the placebo in WA42293 will receive study medication in the three loading doses on days 1, 3 and 5 in a blinded fashion. All three doses will contain PRM-151. Participants previously randomized to the treatment arm in WA42293 will receive study medication in the three loading doses on days 1, 3 and 5 in a blinded fashion. One of the three doses will contain PRM-151, whereas two doses will contain placebo.

Other Name: Zinpentraxin Alfa


Outcome Measures

Primary Outcome Measures :
  1. Percentage of Participants with Adverse Events (AE) [ Time Frame: From baseline until 8 weeks after the final dose ]
    Severity will be determined according to the 5-point severity scale (National Cancer Institute Common Terminology Criteria for Adverse Events, Version 5.0 [NCI CTCAE, v.5.0]).

  2. Percentage of Participants with Infusion Related Reactions (IRRs) and other AEs of Special Interest [ Time Frame: From baseline until 8 weeks after the final dose ]
  3. Percentage of of Participants Permanently Discontinuing Study Treatment due to AEs [ Time Frame: From baseline until 8 weeks after the final dose ]
  4. Change from Baseline in Targeted Clinical Laboratory Test Results [ Time Frame: From baseline until 8 weeks after the final dose ]

Secondary Outcome Measures :
  1. Annual Rate of Change in Forced Vital Capacity (FVC) (mL) [ Time Frame: From baseline until study completion (up tp 4 years) ]
  2. Annual Rate of Change in 6-Minute Walk Distance (6MWD) [ Time Frame: From baseline until study completion (up tp 4 years) ]
  3. Annual Rate of Change in FVC% Predicted [ Time Frame: From baseline until study completion (up tp 4 years) ]
  4. Annual Rate of Change in Carbon Monoxide Diffusing Capacity (DLCO) [ Time Frame: From baseline until study completion (up tp 4 years) ]
  5. Time to Disease Progression [ Time Frame: From the time of randomization until disease progression or death (up tp 4 years) ]
    Time to first occurrence of >=10% absolute decline in % predicted FVC, >=15% relative decline in 6MWD, or death

  6. Survival [ Time Frame: Every 6 Months and at study completion (up to 4 years) ]
  7. IPF-related Mortality [ Time Frame: Every 6 Months and at study completion (up to 4 years) ]
  8. Respiratory-related Mortality [ Time Frame: Every 6 Months and at study completion (up to 4 years) ]
  9. Plasma Concentrations of PRM-151 at Specified Timepoints [ Time Frame: Days 1, 3 and 5, Weeks 4, 12 and 24 ]
  10. Prevalence of Anti-drug Antibodies (ADAs) to PRM-151 at Baseline [ Time Frame: Baseline (Day 1) ]
  11. Percentage of Participants with ADAs During the Study [ Time Frame: Weeks 4, 12 and 24 ]

  • For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraception.
  • For men: agreement to remain abstinent (refrain from heterosexual intercourse) or use a condom, and agreement to refrain from donating sperm.

Exclusion Criteria:

  • Acute respiratory or systemic bacterial, viral, or fungal infection at the first visit of the OLE, or within 2 weeks of the first visit for patients joining Cohort A (from Study PRM-151-202).
