Theravance Biopharma to Host Virtual KOL Investor Event to Review Ampreloxetine Phase 3 Clinical Development Program, Ahead of Topline Data in Q1 2026, on December 8, 2025
DUBLIN, Nov. 20, 2025 /PRNewswire/ -- Theravance Biopharma, Inc. (NASDAQ: TBPH) today announced that it will host a virtual key opinion leader (KOL) investor event on Monday, December 8, 2025 at 10:30 AM ET. To register, click here.
The event will feature Horacio Kaufmann, MD (Dysautonomia Center, NYU Langone Health), who will join company management to discuss the unmet medical need for symptomatic neurogenic orthostatic hypotension (nOH) in patients with multiple system atrophy (MSA), a chronic, debilitating condition caused by autonomic dysfunction that is present in ~80% of patients with MSA. Dr. Kaufmann will also review ampreloxetine as a potential precision therapy approach in development for nOH in patients with MSA.
In anticipation of the Phase 3 CYPRESS study topline results in the first quarter of 2026, the event will also provide an overview of the ongoing CYPRESS study of ampreloxetine, and the strategic design choices of the study, informed by the positive results observed in patients with MSA in the REDWOOD study. Additionally, Company management will summarize ampreloxetine's commercial opportunity and strategy.
A live question and answer session will follow the formal presentations.

About Ampreloxetine
Ampreloxetine, an investigational, once-daily, selective norepinephrine reuptake inhibitor in development for the treatment of symptomatic neurogenic orthostatic hypotension (nOH) in patients with multiple system atrophy (MSA). The unique benefits of ampreloxetine treatment reported in MSA patients from Study 0170 included an increase in norepinephrine levels, a favorable impact on blood pressure, clinically meaningful and durable symptom improvement, and no signal for worsening of supine hypertension. In the U.S., the Company has been granted an Orphan Drug Designation for ampreloxetine for the treatment of symptomatic nOH in patients with MSA and, if results from the ongoing Phase 3 CYPRESS study are supportive, plans to file an NDA for full approval in this indication.
About CYPRESS (Study 0197), a Phase 3 Study
Study 0197 (NCT05696717) has completed enrollment. This is a registrational Phase 3, multi-center, randomized withdrawal study to evaluate the efficacy and durability of ampreloxetine in participants with MSA and symptomatic nOH after 20 weeks of treatment; the primary endpoint of the study is change in the Orthostatic Hypotension Symptom Assessment (OHSA) composite score. The Study includes four periods: screening, open label (12-week period, participants will receive a single daily 10 mg dose of ampreloxetine), randomized withdrawal (eight-week period, double-blind, placebo-controlled, participants will receive a single daily 10 mg dose of placebo or ampreloxetine), and a long-term treatment extension. Secondary outcome measures include change from baseline in Orthostatic Hypotension Daily Activity Scale (OHDAS) item 1 (activities that require standing for a short time) and item 3 (activities that require walking for a short time).
About Multiple System Atrophy (MSA) and Symptomatic Neurogenic Orthostatic Hypotension (nOH)
MSA is a progressive brain disorder that affects movement and balance and disrupts the function of the autonomic nervous system. The autonomic nervous system controls body functions that are mostly involuntary. One of the most frequent autonomic symptoms associated with MSA is a sudden drop in blood pressure upon standing (nOH).1 There are approximately 50,000 MSA patients in the US2 and 70-90% of MSA patients experience nOH symptoms.3 Despite available therapies, many MSA patients remain symptomatic with nOH.4
Neurogenic orthostatic hypotension (nOH) is a rare disorder defined as a fall in systolic blood pressure of ⩾20 mm Hg or diastolic blood pressure of ⩾10 mm Hg, within 3 minutes of standing. Severely affected patients are unable to stand for more than a few seconds because of their decrease in blood pressure, leading to cerebral hypoperfusion and syncope. A debilitating condition, nOH results in a range of symptoms including dizziness, lightheadedness, fainting, fatigue, blurry vision, weakness, trouble concentrating, and head and neck pain.
