|---|---|---|---|---|
| May 26 | Leadership appointment | Positive | +4.5% | New Scientific Advisory Board chair to guide IMP3ACT platform and pipeline. |
| Apr 27 | Conference participation | Positive | +1.6% | Presentations on peptide therapeutics and new preclinical D-MAV data in Boston. |
| Apr 09 | Pipeline progress | Positive | +6.6% | Accelerated execution, AI partnerships, non-dilutive funding and Phase 1 targeted 2027. |
| Apr 06 | Investor event | Positive | +1.6% | Virtual investor event outlining 2026 business outlook and corporate overview. |
| Apr 02 | Nasdaq compliance | Positive | -8.2% | Regained Nasdaq minimum bid compliance but noted one-year mandatory panel monitor. |
24h Move is the share-price change in the day after each event; other market factors may also have contributed.
Recent news has often been followed by positive price reactions, especially around execution and clinical-pathway milestones, with only one notable divergence on a regulatory/compliance update.
Over the last few months, Decoy Therapeutics has steadily communicated its transition toward clinical development. Updates on accelerated execution and a clearly defined clinical path, including a Phase 1 targeted in 2027, drew positive price reactions. Management and scientific leadership enhancements and visibility events also coincided with modest gains. A Nasdaq compliance update on Apr 02 produced a negative move, contrasting with generally constructive responses to pipeline- and strategy-focused announcements, which is consistent with today’s clinically oriented partnership news.

Collaboration supports Phase 1 and Phase 2a human proof-of-concept studies for new antiviral category designed to address multiple viruses with a single adaptable therapeutic
Decoy has engaged hVIVO, a purpose-built, full-service international clinical development partner and global leader in human challenge studies, to support translational modeling, regulatory strategy, clinical development planning, and Phase 1 and Phase 2a human proof-of-concept study preparation for Decoy's lead D-MAV candidate. The outputs will serve as a future rapid preclinical and clinical template for Decoy's growing portfolio of D-MAV drug candidates. Decoy believes its platform architecture may allow for similar clinical trial designs across multiple D-MAV candidates, subject to regulatory feedback.
The initiative brings together Decoy's proprietary IMP³ACT™ platform for D-MAV discovery, which uses AI-enabled peptide design running on Google Cloud, with the translational, regulatory, clinical development and infectious disease drug development expertise and substantial capabilities of hVIVO.
The collaboration is intended to support the clinical advancement of Decoy's lead respiratory antiviral candidates, which are designed to target shared viral mechanisms across multiple respiratory viruses using a single adaptable therapeutic approach.
"Traditional antiviral development has largely followed a one-drug, one-virus model," said Barbara Hibner, Founder and Chief Scientific Officer of Decoy Therapeutics. "Our IMP³ACT platform was built to move faster than that. By combining AI-enabled design with rapid synthesis, we are working to take a D-MAV candidate from concept toward the clinic on a timeline that keeps pace with how viruses actually evolve."
Under the agreement, hVIVO will support Decoy across translational modeling, regulatory strategy, scientific advice preparation, Chemistry Manufacturing and Controls (CMC) consulting, non-clinical development support, and preparation of key clinical and regulatory documentation required for European and
Yamin 'Mo' Khan, Chief Executive Officer of hVIVO, said "The antiviral landscape continues to evolve as sponsors seek new approaches to address respiratory viruses and strengthen pandemic preparedness. Decoy's programmes represent a differentiated approach, and we are pleased to be supporting the company as it progresses towards the clinic. This collaboration highlights the growing demand for integrated development partners that can support biotechnology companies from early development strategy through to clinical execution."
In parallel, Decoy intends to utilize outputs generated through hVIVO's consultancy program to inform clinical development strategy, first-in-human dose selection, translational pharmacology planning, challenge study design considerations, and Phase 2a human proof-of-concept readiness activities. The combined effort is designed to support Decoy's transition into the clinic by aligning translational science, regulatory planning, and early clinical execution around a unified development pathway.
"Viral disease shouldn't require a new drug for every new threat, and it shouldn't take years to reach the people who need it most," said Rick Pierce, Chief Executive Officer, Decoy Therapeutics. "We're building D-MAVs as a new category of antiviral, one designed to work across multiple viruses and built from the start for the markets, governments, and global health partners who can get them to patients at scale. Our partnership with hVIVO is a critical step toward proving that approach in human studies."
Decoy's lead programs are focused on respiratory viral infections and are designed to support broader preparedness strategies against evolving and emerging viral threats. The company believes its platform architecture may enable more rapid optimization and adaptation compared to traditional antiviral development approaches. The company expects the collaboration activities to support filing IND/CTAs, translational package development, regulatory engagement preparation, and the design of future phase 1 and human proof-of-concept studies.
