**Theravance Biopharma Completes Enrollment in Pivotal Phase 3 CYPRESS Study of Ampreloxetine in Patients with Symptomatic Neurogenic Orthostatic Hypotension due to Multiple System Atrophy**

&nbsp;&nbsp;&nbsp;&nbsp;· *Topline results anticipated in Q1 2026 and ,* *if successful, planning for expedited NDA submission* 

&nbsp;&nbsp;&nbsp;&nbsp;· *If approved, ampreloxetine could address a critical unmet need as the first therapy with the potential to provide durable benefit for the 40,000 patients in the U.S. with symptomatic neurogenic orthostatic hypotension (nOH) in patients with multiple system atrophy (MSA)* 

&nbsp;&nbsp;&nbsp;&nbsp;· *Ampreloxetine has Orphan Drug Designation in the U.S., underscoring the unmet need in symptomatic nOH due to MSA* 

**DUBLIN, August 25, 2025** -- Theravance Biopharma, Inc. ("Theravance Biopharma" or the "Company") (NASDAQ: TBPH), today announced completion of enrollment in the open-label portion of its pivotal Phase 3 CYPRESS study in patients with symptomatic neurogenic orthostatic hypotension (nOH) due to multiple system atrophy (MSA), a rare and progressive neurodegenerative disorder. nOH is a devastating condition affecting approximately 80% of MSA patients and is characterized by sudden drops in blood pressure upon standing, leading to symptoms such as dizziness, fainting, and blurry vision. These symptoms can lead to serious consequences, including falls, disability, and loss of independence. Despite its severity and impact, there is a lack of effective and durable treatment options that are specifically designed to treat nOH in patients with MSA.

"nOH is one of the most debilitating manifestations of MSA, which affects about 40,000 patients in the U.S. alone. Yet current therapies often fail to provide lasting symptoms relief, require frequent dosing and carry a boxed warning for supine hypertension," said Dr. Horacio Kaufmann, F. B. Axelrod Professor of Neurology and Professor of Medicine at NYU Grossman School of Medicine. "Ampreloxetine is designed to address the underlying cause of nOH. In Study 0170, it showed compelling improvement in OHSA composite score without worsening supine hypertension.<sup>1</sup> If these benefits are confirmed, I would expect to use ampreloxetine in the majority of my patients living with nOH due to MSA. I am encouraged that enrollment in CYPRESS, the first randomized-withdrawal trial designed specifically for the MSA population, has been completed, and I look forward to seeing the data early next year."

The registration-enabling Phase 3 CYPRESS (<u>NCT05696717</u>) study is a global, randomized-withdrawal study evaluating ampreloxetine in patients with symptomatic nOH due to clinically diagnosed MSA. Patients were enrolled in the 12-week open-label portion of the study at sites across four continents. At the end of the open-label portion, responders are randomized 1:1 to continue ampreloxetine or switch to placebo for eight weeks in the randomized-withdrawal portion of the study. The primary endpoint is change in orthostatic hypotension symptom assessment (OHSA) composite score from randomized-withdrawal baseline to Week 8.

"Completing enrollment in CYPRESS marks a major step toward bringing this potentially transformative therapy to patients with symptomatic nOH due to MSA – an underserved patient population in dire need for a new, effective and durable treatment with a favorable safety profile," said Áine Miller, Ph.D., Head of Development at Theravance Biopharma. "Ampreloxetine is intended to target the root cause driving MSA-associated nOH by selectively inhibiting norepinephrine reuptake, and demonstrated benefit in this patient population in Study 0170. The CYPRESS randomized withdrawal trial was designed with insights from Study 0170, and we are confident that, along with our careful study execution, this derisked program strongly positions us to evaluate ampreloxetine's full potential in this patient population."

![](tm2524263d1_ex99-1img01.jpg)

The Company expects to report topline data from the Phase 3 CYPRESS trial in Q1 2026. In parallel, Theravance is preparing for an expedited NDA submission following the results and is planning to request priority FDA review, if data are supportive. This milestone reinforces our strategic focus and delivers on Theravance's commitment to advancing high-impact catalysts, as previously highlighted in our recent Q2 earnings call.

**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 US, 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 the Phase 3 CYPRESS (Study 0197) Study**

The CYPRESS Study (<u>NCT05696717</u>) 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 the Phase 3 SEQUOIA (Study 0169) and REDWOOD (Study 0170) Studies**

Study 0169 (<u>NCT03750552</u>) was a Phase 3, 4-week, multi-center, randomized, double-blind, placebo-controlled, parallel-group study to evaluate the efficacy and safety of ampreloxetine compared to placebo in patients with symptomatic nOH (n=195). Patients from Study 0169 were eligible to enter into Study 0170 (<u>NCT03829657</u>), a Phase 3, multi-center, 22-week study comprising a 16-week open-label period and a 6-week double-blind, placebo-controlled, randomized withdrawal period to evaluate the sustained benefit in efficacy and safety of ampreloxetine in patients with symptomatic nOH. The primary endpoint for Study 0170 of treatment failure at week 6 was defined as a worsening of both Orthostatic Hypotension Symptom Assessment Scale (OHSA) question #1 and Patient Global Impression of Severity (PGI-S) scores by 1.0 point. After Study 0169 did not meet its primary endpoint, the Company took actions to close out the ongoing clinical program including Study 0170. The study was more than 80% enrolled (n=128/154 planned) despite stopping early. The primary endpoint was not statistically significant for the overall population of patients which included patients with Parkinson's disease, pure autonomic failure and MSA (odds ratio=0.6; p-value=0.196). The pre-specified subgroup analysis by disease type suggests the benefit seen in patients receiving ampreloxetine was largely driven by MSA patients (n=40). An odds ratio of 0.28 (95% CI: 0.05, 1.22) was observed in MSA patients indicating a 72% reduction in the odds of treatment failure with ampreloxetine compared to placebo. The benefit to MSA patients was observed in multiple endpoints including OHSA composite, Orthostatic Hypotension Daily Activities Scale (OHDAS) composite, Orthostatic Hypotension Questionnaire (OHQ) composite and OHSA #1.<sup>1</sup>

**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).<sup>2</sup> There are approximately 50,000 MSA patients in the US<sup>3</sup> and 70-90% of MSA patients experience nOH symptoms.<sup>4</sup> Despite available therapies, many MSA patients remain symptomatic with nOH.

Neurogenic orthostatic hypotension (nOH) is a rare disorder defined as a fall in systolic blood pressure of ³ 20 mm Hg or diastolic blood pressure of ³ 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 disorder, nOH results in a range of symptoms including dizziness, lightheadedness, fainting, fatigue, blurry vision, weakness, trouble concentrating, and head and neck pain.
