Active Studies

The Pulmonary Fibrosis Foundation Patient Registry will collect data on at least 2,000
patients with interstitial lung disease (ILD) at approximately 40 clinical sites in the US.
The Registry is targeting enrollment of approximately 60% of the 2,000 ILD participants to
have idiopathic pulmonary fibrosis (IPF). The aim of the Registry is to create a cohort of
well-characterized patients with interstitial lung disease (ILD) for participation in
retrospective and prospective research

The COMMEND Study will assess the safety and effectiveness of FLX-787 in men and women with
Motor Neuron Disease [including Amyotrophic Lateral Sclerosis (ALS), Primary Lateral
Sclerosis (PLS) or Progressive Muscular Atrophy (PMA)] experiencing muscle cramps.
Participants will be asked to take two study products during the course of the study. One of
these study products will be a placebo.

Approximately 120 participants in approximately 30 study centers across the United States are
expected to take part. Participants will be in the study for approximately 3 months and visit
the study clinic 3 times.

The primary objective of this study is to document lymphedema rates in patients requiring
regional nodal irradiation (RNI) who receive hypofractionated radiation as compared to
conventional radiation.

This is a multicenter, randomized (1:1; oral treprostinil to placebo), double-blind,
placebo-controlled study in subjects with World Health Organization (WHO) Group 2 pulmonary
hypertension (PH) associated with heart failure with preserved ejection fraction (HFpEF).
Once randomized, subjects will take the initial dose of study drug at the study site on the
day of randomization. Subjects will return to the study site for visits scheduled at Weeks 6,
12, 18, and 24. The treatment phase of the study will last approximately 24 weeks.

This is an open-label study to evaluate the safety of continued therapy with oral
treprostinil in subjects who have completed Study TDE-HF-301. This study will provide
long-term, open-label data regarding the effect of continued long-term oral treprostinil
therapy for the treatment of pulmonary hypertension (PH) associated with heart failure with
preserved ejection fraction (HFpEF). Subject visits will occur at Baseline, Weeks 6, 12, 18,
24, and every 12 weeks thereafter until either oral treprostinil becomes commercially
available to treat PH associated with HFpEF or the study is discontinued by the Sponsor.
