Travere Therapeutics Announces Voluntary Pause of Enrollment in the Phase 3 HARMONY Study of Pegtibatinase Related to Commercial Manufacturing Scale-Up
Travere Therapeutics (Nasdaq: TVTX) has announced a voluntary pause in enrollment for its Phase 3 HARMONY Study of pegtibatinase, a potential treatment for classical homocystinuria (HCU). This decision was made to address necessary process improvements in manufacturing scale-up for commercial production. Currently enrolled patients will continue to receive study medication from unaffected small-scale batches.
The pause was initiated after the company determined that the desired drug substance profile was not achieved in the recent scale-up process. Travere expects to restart enrollment in the HARMONY Study no earlier than 2026. As a result, the company anticipates a reduction in research and development expenses by more than $30 million in 2025 compared to 2024. Travere's cash reserves of $325.4 million as of June 30, 2024, are expected to support operations into 2028.
Travere Therapeutics (Nasdaq: TVTX) ha annunciato una pausa volontaria nell'arruolamento per il suo studio di fase 3 HARMONY su pegtibatinase, un potenziale trattamento per l'omocistinuria classica (HCU). Questa decisione è stata presa per affrontare i miglioramenti necessari nei processi di produzione su larga scala per la produzione commerciale. I pazienti attualmente arruolati continueranno a ricevere il farmaco dello studio da lotti piccoli e non influenzati.
La pausa è stata avviata dopo che l'azienda ha determinato che il profilo della sostanza farmaceutica desiderato non era stato raggiunto nel recente processo di scala. Travere prevede di riavviare l'arruolamento nello studio HARMONY non prima del 2026. Di conseguenza, l'azienda si aspetta una riduzione delle spese di ricerca e sviluppo di oltre 30 milioni di dollari nel 2025 rispetto al 2024. Le riserve di cassa di Travere pari a 325,4 milioni di dollari al 30 giugno 2024, dovrebbero supportare le operazioni fino al 2028.

Insights
The voluntary pause in enrollment for Travere Therapeutics' Phase 3 HARMONY study of pegtibatinase is a significant setback for the company's pipeline. This delay, caused by manufacturing scale-up issues, pushes the potential restart of enrollment to 2026, substantially extending the timeline for this key program.
While the company maintains confidence in pegtibatinase's potential as a first disease-modifying therapy for classical homocystinuria (HCU), this delay will likely impact investor sentiment and the company's near-term prospects. The expected

The manufacturing scale-up issues encountered by Travere Therapeutics highlight the complexities involved in transitioning from small-scale production to commercial-scale manufacturing for biologics. The failure to achieve the desired drug substance profile during scale-up is a critical concern that requires careful analysis and resolution.
This situation underscores the importance of robust process development and the challenges of maintaining product quality and consistency at larger scales. The company's decision to pause enrollment to address these issues is prudent, as it prevents potential complications that could arise from using suboptimal material in clinical trials.
The timeline for resolving these manufacturing challenges, with enrollment restart not expected until 2026, suggests that significant process optimization and validation work is required. This extended timeline may also involve regulatory interactions to ensure that any process changes meet regulatory requirements for pivotal trial material and eventual commercial production.
Company to host conference call today at 4:30 p.m. ET
SAN DIEGO, Sept. 26, 2024 (GLOBE NEWSWIRE) -- Travere Therapeutics, Inc., (Nasdaq: TVTX) today announced a voluntary pause of enrollment in the Phase 3 HARMONY Study evaluating pegtibatinase for the treatment of classical homocystinuria (HCU). The voluntary enrollment pause enables the Company to work to address necessary process improvements in manufacturing scale-up to support commercial scale manufacturing as well as full enrollment in the HARMONY Study. Patients currently enrolled in pegtibatinase studies continue to receive study medication from small scale batches which are unaffected by the scale-up process. Currently enrolled patients will be able to continue on study medication as scheduled for the duration of the trials they are participating in.
The voluntary enrollment pause was enacted following the Company’s determination that the desired drug substance profile was not achieved in the recent scale-up process. The Company is in the process of notifying all study investigators of the decision to pause enrollment of new patients into the study until additional material is available.
“We believe the potential for pegtibatinase to become the first disease-modifying therapy for classical HCU remains unchanged. Our internal team and external manufacturing partners have extensive biologics expertise, and we are confident that we will be able to make the necessary manufacturing process improvements to continue with this pivotal program. We remain committed to supporting the patients currently enrolled in our clinical trials while working with our manufacturing partners to optimize our commercial-scale manufacturing process,” said Bill Rote, Ph.D., senior vice president of research and development at Travere Therapeutics.
The Company expects to further evaluate the necessary commercial process improvements to enable the continuation of the Phase 3 program and anticipates the earliest date to restart enrollment in the Phase 3 HARMONY Study will be in 2026. Previously planned investments related to clinical enrollment in HARMONY and large-scale production are expected to be delayed beyond 2025. Together with the expected decline in costs associated with the development of sparsentan as the Phase 3 programs advance towards completion, the Company now estimates that research and development expenses may be reduced by more than

About Classical Homocystinuria
Classical homocystinuria (HCU) is a rare genetic metabolic disorder caused by a deficiency in the enzyme cystathionine beta synthase (CBS). CBS is a pivotal enzyme that is essential for the management of methionine and cysteine in the body. Classical HCU leads to toxic levels of homocysteine that can result in life-threatening thrombotic events such as stroke, pulmonary embolism and deep vein thrombosis, ophthalmologic and skeletal complications, as well as developmental delay. Current treatment options are limited to protein-restricted diet and use of vitamin B6 and betaine.
About Pegtibatinase
Pegtibatinase is an investigational PEGylated, recombinant enzyme replacement therapy designed to address the underlying cause of classical HCU. In preclinical studies, pegtibatinase has demonstrated an ability to reduce total homocysteine levels and improve clinical parameters. In December 2023 the Company initiated the pivotal Phase 3 HARMONY Study to support the potential approval of pegtibatinase for the treatment of classical HCU. The HARMONY Study is a global, randomized, multi-center, double-blind, placebo-controlled Phase 3 clinical trial designed to evaluate the efficacy and safety of pegtibatinase as a novel treatment to reduce total homocysteine (tHcy) levels. In May 2023 the Company announced that data from four patients treated with the highest dose of pegtibatinase in the Phase 1/2 COMPOSE Study showed a clinically meaningful
