Exhibit 99.1
Theravance Biopharma, Inc. Announces Results from Study 0170, a Second Phase 3 Study of Ampreloxetine, in Patients with Symptomatic Neurogenic Orthostatic Hypotension (nOH)
| ● | Results from Study 0170 show a benefit in study patients with multiple system atrophy (MSA) |
| ● | Company beginning discussions with potential strategic partners and planning health authority interactions to expedite ampreloxetine as a possible treatment option for patients with symptomatic nOH |
| ● | Company remains focused on respiratory therapeutics, value creation for shareholders and reiterates plan to be sustainably cash-flow positive by the second half of the year |
DUBLIN, April 4, 2022 /PRNewswire/ -- Theravance Biopharma, Inc. (“Theravance Biopharma” or the “Company”) (NASDAQ: TBPH) today announced results from the second Phase 3 study, Study 0170 (n=128 out of n=154 planned), assessing the durability of clinical effect of ampreloxetine compared to placebo for the treatment of symptomatic nOH. Study 0170 was a 22-week Phase 3 study comprised of a 16-week open-label period followed by a 6-week double-blind, placebo-controlled, randomized withdrawal period. The primary endpoint of treatment failure at week 6 of the randomized withdrawal period 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.
The primary endpoint was not statistically significant for the overall population of patients which included patients with Parkinson’s disease (PD), pure autonomic failure (PAF) and MSA (odds ratio=0.6; p-value=0.196). The odds ratio suggests that patients receiving ampreloxetine had a 40% reduction in the odds of treatment failure compared to placebo.
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 (see figure below). Notably, patients withdrawn to placebo had a clinically relevant decrease in standing blood pressure; there was no decrease for patients remaining on ampreloxetine. While the same benefit was not apparent in patients with PD or PAF, the Company continues to analyze the data to better understand this observation. Throughout the study, there was no indication of worsening of supine hypertension based on 24-hour monitoring. Data suggest that ampreloxetine was well-tolerated and no new safety signals were identified.
OHQ questionnaire Composite scores and individual items for MSA patients
“MSA is a devastating and debilitating disease with no effective disease modifying treatment. There is an urgency to treat MSA patients suffering with nOH due to the impact on quality of life and the extreme caregiver burden. Ampreloxetine appears to improve a narrow, but critically important group of symptoms related to blood pressure control, and along with the safety profile, may represent a potential therapy for MSA patients,” said Roy Freeman, MBChB, Professor of Neurology, Director, Center for Autonomic and Peripheral Nerve Disorders, Beth Israel Deaconess Medical Center, who assisted in the design and interpretation of the study.
“At Theravance Biopharma, we are guided by patient outcomes. Given the clear unmet need for MSA patients suffering from symptomatic nOH, we are engaging potential partners and planning health authority interactions to determine a path forward in hopes of expediting ampreloxetine as a possible treatment option for people with MSA,” said Rick E Winningham, Chief Executive Officer, Theravance Biopharma. “Concurrently, we are executing against our business plan and remain disciplined in capital allocation, maximizing shareholder value and re-iterate our goal to be sustainably cash-flow positive by the second half of this year.”
Disclosure: Dr. Freeman is a consultant serving as an advisor for drug development and clinical trial design for Theravance Biopharma.
Study 0170 (REDWOOD) Ampreloxetine Phase 3 Results
About the Phase 3 Study
Study 0170 (NCT03829657) was a 22-week Phase 3 study comprised of a 16-week open-label period
and a 6-week double-blind, placebo-controlled, randomized withdrawal period. The primary endpoint 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.
About Symptomatic nOH
Neurogenic orthostatic hypotension (nOH) is a rare disorder defined as a sustained orthostatic fall in systolic blood pressure (SBP)
of ≥ 20 mm Hg or diastolic blood pressure (DBP) of ≥ 10 mm Hg within three 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. nOH is caused by autonomic nervous system malfunction and is associated with
several underlying medical conditions including multiple system atrophy (MSA), pure autonomic failure (PAF), and Parkinson’s disease
(PD).
About Multiple System Atrophy
(MSA)
MSA (formerly Shy-Drager syndrome) is a rare, rapidly
progressive, severely debilitating, and fatal neurodegenerative disease that leads to death within a median of seven to 10 years after
the onset of symptoms. MSA shares many Parkinson’s disease-like symptoms, such as slow movement, rigid muscles and poor balance.
The primary sign of multiple system atrophy is postural (orthostatic) hypotension. A person with MSA can also develop dangerously high
blood pressure levels while lying down (supine hypertension). Other manifestations include: urinary and bowel dysfunction, constipation,
incontinence, sweating abnormalities, sleep disorders, sexual dysfunction, cardiovascular problems and psychiatric problems. The most
common causes of death in MSA are infection and cardiopulmonary complications. Currently, MSA patients receive only symptomatic and palliative
therapies as there are no disease-modifying treatments and no cure.
About Ampreloxetine
Ampreloxetine (TD-9855) is an investigational, Theravance Biopharma-discovered, potent, long-acting, oral, once-daily norepinephrine
reuptake inhibitor in development for the treatment of symptomatic neurogenic orthostatic hypotension (nOH) with patent protection until
2037 in the US. In addition to the Phase 3 clinical program, Theravance Biopharma has conducted a comprehensive non-clinical and clinical
pharmacology program. Ampreloxetine has been evaluated in over 800 patients in clinical studies of fibromyalgia, attention deficit hyperactivity
disorder (ADHD) and symptomatic nOH.
