NEW HAVEN, Conn., Aug. 11, 2022 /PRNewswire/ -- Trevi Therapeutics, Inc. (Nasdaq: TRVI), a clinical-stage biopharmaceutical company developing an investigational therapy Haduvio™ (oral nalbuphine ER) for the treatment of prurigo nodularis and chronic cough in adults with idiopathic pulmonary fibrosis (IPF), today announced financial results for the quarter ended June 30, 2022, as well as provided business updates.

Trevi’s topline data expected for Ph2b/3 PRISM study this quarter and full results for Ph2 CANAL study in Q3

"The positive trial results reported this quarter in the treatment of prurigo nodularis not only further support the continued development of Haduvio in another therapeutic indication with a high unmet need, but also reaffirms the mechanism of action and the importance of having both a peripheral and centrally active therapy," said Jennifer Good, President and CEO of Trevi Therapeutics. "As a next step in our prurigo nodularis program, we plan to request an end of phase 2 meeting with the FDA. In our chronic cough in IPF program, we are looking forward to providing topline efficacy and safety data on the full set of subjects enrolled in the completed Phase 2 CANAL study this quarter. We are actively preparing for the next trial in chronic cough in IPF and are looking forward to discussing the program and trial plan with the FDA at a meeting scheduled for this quarter."

Key Business Updates

Phase 2b/3 PRISM trial of Haduvio in the treatment of Prurigo Nodularis

As previously announced in the Phase 2b/3 PRISM trial, results comparing subjects randomized to Haduvio (n=168) or placebo (n=176) achieved the primary and two key secondary endpoints. In addition, the Company has received the analysis on the final key secondary endpoint, the PROMIS sleep scale, which also achieved that endpoint with statistical significance at week 14. Below is a summary of the primary and all key secondary endpoints:

  • 25% of Haduvio subjects evaluated at week 14 met the primary endpoint of a 4-point reduction in the Worst Itch Numerical Rating Scale from baseline compared to 14% of placebo subjects (p=0.0157).
  • Haduvio subjects experienced significantly greater improvements in ItchyQoL vs. placebo (p=0.0002) at week 14, which was statistically significant across each of the three domains (symptoms, functional limitations, and emotions). ItchyQoL is used to measure how pruritus impacts a subject's quality of life.
  • 55% of Haduvio subjects had at least a 1-category improvement in the 5-point scale in their Prurigo Activity Score (PAS) (pruriginous lesions with excoriations), vs. 38% on placebo (p=0.006) as evaluated at week 14.
  • Haduvio subjects experienced significantly greater improvements in the PROMIS sleep disturbance short form 8a vs. placebo (p=0.0002) at week 14. The first assessment of PROMIS was made at week 6 of the trial and results at week 6 also demonstrated a statistically significant improvement.

Private Placement

  • Completed a $55 million private placement in April 2022 to further the clinical development of Haduvio.

Second Quarter 2022 Financial Highlights

Cash position: As of June 30, 2022, the Company had total cash, cash equivalents and marketable securities of $78.9 million.

Research and development (R&D) expenses: R&D expenses for the second quarter of 2022 were $5.1 million compared to $6.5 million in the same period in 2021. The decrease was primarily due to reduced purchases of clinical trial supplies and clinical trial subject recruitment costs, a reduction in our use of consulting services and the non-recurrence of professional recruiting fees related to hirings in the prior year period.

General and administrative (G&A) expenses: G&A expenses were $2.7 million in the second quarter of 2022 and the second quarter of 2021.

Net loss: For the second quarter of 2022, the Company reported a net loss of $8.1 million, compared to a net loss of $9.8 million in the same period in 2021. The decrease was primarily due to the decrease in R&D expenses.

About Trevi Therapeutics, Inc.
Trevi Therapeutics, Inc. is a clinical-stage biopharmaceutical company focused on the development and commercialization of the investigational therapy Haduvio for the treatment of prurigo nodularis and chronic cough in adults with idiopathic pulmonary fibrosis. These conditions share a common pathophysiology that is mediated through opioid receptors in the central and peripheral nervous systems.

Founded in 2011, Trevi Therapeutics is headquartered in New Haven, CT.

About Haduvio
Haduvio, an investigational therapy, is an oral extended-release (ER) formulation of nalbuphine. Nalbuphine is a mixed ĸ-opioid receptor agonist and µ-opioid receptor antagonist that has been approved and marketed as an injectable for pain indications for more than 20 years in the United States and Europe. The ĸ- and µ-opioid receptors are known to be critical mediators of itch, cough and certain movement disorders. Nalbuphine's mechanism of action may also mitigate the risk of abuse associated with µ-opioid agonists because it antagonizes, or blocks, µ-opioid receptors. Parenteral nalbuphine is not currently scheduled as a controlled substance by the DEA in the United States or by regulatory authorities in most of Europe. Trevi intends to propose Haduvio as the trade name for nalbuphine ER. Nalbuphine ER has been granted Fast Track designation by the FDA for the treatment of itch in patients with prurigo nodularis. Its safety and efficacy have not been evaluated by any regulatory authority.
