Phase 2 Clinical Trial of MNKD-201 (Nintedanib Dry Powder Inhalation) in Patients With Idiopathic Pulmonary Fibrosis (INFLO-2)

July 23, 2026 updated by: Mannkind Corporation

A Randomized, Double-Blind, Placebo-Controlled, Phase 2 Clinical Trial of the Efficacy and Safety of MNKD-201 (Nintedanib Dry Powder Inhalation) in Patients With Idiopathic Pulmonary Fibrosis Followed by an Open-Label Extension

This trial is a randomized, double-blind, placebo-controlled study evaluating the safety and preliminary efficacy of inhaled Nintedanib Dry Powder Inhalation (DPI) in adults with idiopathic pulmonary fibrosis (IPF). Participants are randomized to receive either 2 mg QID, 4 mg BID, or matching placebo for 12 weeks, followed by a 24-week open-label extension in which all participants receive active treatment. The primary focus is on safety-particularly bronchospasm events, lung function changes (FEV1, FEV1/FVC), and adverse event rates and assessing the effectiveness of nintedanib DPI in treating IPF.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No
