Recent INSM news has mostly seen modest price alignment, with some divergence on scientific conference and HR-related updates.
Over the past two months, Insmed has reported strong business growth and active clinical development. A Jan 9, 2026 update cited $606.4M in 2025 net product revenue and higher ARIKAYCE and BRINSUPRI contributions, prompting a 3.35% gain. Conference-related announcements, such as ERS 2025 scientific presentations and the J.P. Morgan appearance, produced mixed reactions. Routine equity compensation grants in Dec 2025 drew a slight negative move. Today’s TPIP-focused PVRI presentations fit the pattern of data-rich, visibility-building clinical communication.
Market Pulse Summary
This announcement increases scientific visibility for TPIP through four presentations at PVRI 2026, spanning Phase 3 PALM-PAH study design, Phase 2b PAH data, advanced imaging analyses, and preclinical vasodilation work. It follows a strong business update with $606.4M in 2025 net product revenue and expanding late-stage programs. Investors may watch how upcoming Phase 3 TPIP and other pulmonary trial readouts compare with these earlier Phase 2b and translational data sets.

—Abstracts Include the Phase 3 PALM-PAH Study Design, a Presentation of the Previously Disclosed Topline Phase 2b PAH Data, a Functional Respiratory Imaging Analysis from the Phase 2b Study in Pulmonary Arterial Hypertension (PAH), and Pulmonary Vasodilation Data in Rat Models—
Presentations will feature the Phase 3 PALM-PAH study design and an encore presentation of the topline results from the Phase 2b study of TPIP in pulmonary arterial hypertension (PAH). Additionally, a new Functional Respiratory Imaging analysis from the Phase 2b PAH study, as well as data evaluating the pulmonary vasodilatory effect of TPIP in rat models will be presented.
"We are pleased that TPIP will have a significant presence at this year's PVRI 2026 congress, reflecting the growing body of evidence supporting its potential to become the prostanoid of choice," said Martina Flammer, M.D., MBA, Chief Medical Officer, Insmed. "Collectively, these Phase 2b clinical, advanced imaging, and translational preclinical data provide a strong foundation as we initiate multiple Phase 3 programs, including the PALM-PAH study, with the goal of improving outcomes for patients."

About TPIP
Treprostinil palmitil inhalation powder (TPIP) is a dry powder formulation of treprostinil palmitil, a treprostinil prodrug consisting of treprostinil linked by an ester bond to a 16-carbon chain. Developed entirely in Insmed's laboratories, TPIP is being evaluated as a once-daily therapy for the treatment of patients with PAH, PH-ILD, and other rare and serious pulmonary disorders. TPIP is administered in a capsule-based inhalation device. TPIP is an investigational drug product that has not been approved for any indication in any jurisdiction.
About the Phase 2b Study
The Phase 2b study of treprostinil palmitil inhalation powder (TPIP) in patients with PAH was a randomized, double-blind, multicenter, placebo-controlled study designed to evaluate the efficacy, safety, and pharmacokinetics of TPIP, administered once daily, in patients diagnosed with PAH (World Health Organization Group 1). The study was conducted at 44 sites and enrolled 102 adult participants. Patients started at a dose of 80 µg once daily (TPIP or matching placebo) and were titrated up to their maximum tolerated dose, or to the maximum allowable dose of 640 µg, once daily over a three-week period, with the possibility of a final dose increase occurring at Week 5. Patients self-administered TPIP or placebo using a capsule-based inhalation device. The primary endpoint was change from baseline in pulmonary vascular resistance (PVR) versus placebo at Week 16. Secondary endpoints were six-minute walk distance (6MWD), N-terminal pro b-type natriuretic peptide (NT-proBNP) concentrations, pharmacokinetics, and safety/tolerability. Patients who completed the study could enroll in a long-term open-label extension, with the option to titrate up to a maximum tolerated dose of 1,280 µg once daily.
About PAH
PAH is a serious, progressive, rare disease in which the blood vessels in the lungs narrow or become obstructed, leading to high blood pressure in the pulmonary arteries. The most common symptoms include shortness of breath, chest pain, dizziness or fainting, fatigue, and weakness. It is estimated that approximately 35,000 patients in the

Such risks, uncertainties and other factors include, among others, the following: the risk that the full data set from the TPIP PAH study or data generated in further clinical trials of TPIP will not be consistent with the topline results of the TPIP PAH study; failure to successfully conduct future clinical trials for TPIP, such as the Company's planned Phase 3 program for TPIP, including due to the Company's potential inability to enroll or retain sufficient patients to conduct and complete the trials or generate data necessary for regulatory approval, among other things; development of unexpected safety or efficacy concerns related to TPIP; failure of third parties on which the Company is dependent to manufacture sufficient quantities of TPIP for clinical needs, to conduct the Company's clinical trials, or to comply with the Company's agreements or laws and regulations that impact the Company's business or agreements with the Company; failure to obtain regulatory approval for TPIP; inaccuracies in the Company's estimates of the size of the potential markets for TPIP or in data the Company has used to identify physicians; expected rates of patient uptake, duration of expected treatment, or expected patient adherence or discontinuation rates, if TPIP is approved; inability of the Company or the Company's third-party manufacturers to comply with regulatory requirements related to TPIP; the Company's inability to obtain adequate reimbursement from government or third-party payors for TPIP or acceptable prices for TPIP, if approved; restrictions or other obligations imposed on us by agreements related to TPIP and failure to comply with our obligations under such agreements; risks that the Company's clinical studies will be delayed or that serious side effects will be identified during drug development; the strength and enforceability of the Company's intellectual property rights or the rights of third parties; and the cost and potential reputational damage resulting from litigation to which the Company may become a party, including product liability claims.
The Company may not actually achieve the results, plans, intentions or expectations indicated by the Company's forward-looking statements because, by their nature, forward-looking statements involve risks and uncertainties because they relate to events and depend on circumstances that may or may not occur in the future.
