Clinical Research

Pacific Pulmonary Medical Group actively pursues promising research, offering patients the opportunity to be among the first to benefit from advances in medicine. Everyday research uncovers new information about diseases and their treatment. By taking part in a research study, you can help to prove the efficacy and new indications of both new and current medications.

Pacific Pulmonary Medical Group physicians are proud to be part of a global medical community committed to finding the cures of tomorrow.
We are currently enrolling for the following Clinical Trials:


A Randomized , Double Blind, Placebo-Controlled Phase II/III study to evaluate the safety and efficacy of inhaled Treprostinil in subjects with Pulmonary Hypertension due to Parenchymal Lung Disease including:- Idiopathic Interstitial Pneumonia, Interstitial Lung Disease, or Combined Pulmonary Fibrosis and Emphysema.



A clinical research study of Inhaled Treprostinil and Placebo for the treatment of Pulmonary Hypertension, Interstitial Lung Disease or Combined Pulmonary Fibrosis and Emphysema


A Multicenter, Randomized, Double-Blinded, Placebo-Controlled Trial to Evaluate the Safety and Efficacy of Inhaled Treprostinil in Subjects With Pulmonary Hypertension Due to Parenchymal Lung Disease


This is a multicenter, randomized (1:1 inhaled treprostinil: placebo), double-blinded, placebo-controlled trial to evaluate the safety and efficacy of inhaled treprostinil in subjects with pre-capillary pulmonary hypertension (PH) associated with interstitial lung disease (ILD) including combined pulmonary fibrosis and emphysema (CPFE). The study will include about 314 patients at approximately 100 clinical trial centers. The treatment phase of the study will last approximately 16 weeks. Patients who complete all required assessments will also be eligible to enter an open-label, extension study (RIN-PH-202).

  • Right Heart Catherization (RHC) within one year prior to randomization
  • Baseline 6MWD ≥ 100 meters
  • Baseling diffusing capacity of the lungs for carbon monoxide (DLCO) < 50%
