Key Terms

contingent value right, primary endpoint, clinical efficacy
3 terms
contingent value right financial
"Milestone Triggers Release of Shares to Kintara Contingent Value Right (CVR) Holders"
A contingent value right is a special security that gives its holder the right to receive one or more future payments only if specified events happen, such as a product reaching a sales target or getting regulatory approval. It matters to investors because it offers potential extra payout tied to uncertain outcomes—like a bet that a project will succeed—so it can add upside to a deal while also carrying extra risk and valuation uncertainty.
primary endpoint medical
"met its primary endpoint demonstrating safety with signs of clinical efficacy"
The primary endpoint is the single main result a clinical study is designed to measure to decide if a treatment works, like the finish line in a race that tells you who won. Investors care because meeting or missing this goal drives regulatory decisions, future sales expectations and stock value — it turns trial data into a clear yes-or-no signal about a drug’s commercial prospects.
clinical efficacy medical
"demonstrating safety with signs of clinical efficacy following eight weeks"
Clinical efficacy measures how well a medical treatment, drug, or device achieves its intended health effect in controlled clinical trials — essentially whether it works for the condition it was developed to treat. For investors, efficacy is a key indicator of regulatory approval chances, market demand and commercial potential: stronger, clear trial results lower development risk and can significantly boost a product’s revenue prospects, much like a proven prototype convincing buyers and regulators.

TAMPA, Fla., Dec. 15, 2025 /PRNewswire/ -- TuHURA Biosciences, Inc. (NASDAQ:HURA) ("TuHURA" or the "Company"), a Phase 3 immuno-oncology company developing novel therapeutics to overcome resistance to cancer immunotherapy, today announced that Kintara's REM-001 clinical trial of ten metastatic cutaneous breast cancer patients met its primary endpoint demonstrating safety with signs of clinical efficacy following eight weeks of follow-up for such patients. 

Pursuant to the terms of the Contingent Value Rights Agreement dated as of October 18, 2024, by and between TuHURA Biosciences, Inc. and the rights agent, Equiniti Trust Company, LLC (the "CVR Agreement"), as a result of the trial and the completion of the follow-up, the milestone required for the release of an aggregate of 1,539,958 shares of TuHURA common stock to legacy Kintara Therapeutics stockholders has been achieved.  The holders of CVRs are entitled to receive shares of TuHURA common stock, subject to the terms of the CVR Agreement and any applicable withholding.

About TuHURA Biosciences, Inc.

TuHURA Biosciences, Inc. (Nasdaq: HURA) is a Phase 3 immuno-oncology company developing novel technologies to overcome primary and acquired resistance to cancer immunotherapy, two of the most common reasons cancer immunotherapies fail to work or stop working in the majority of patients with cancer.

TuHURA's lead innate immune agonist, IFx-2.0, is designed to overcome primary resistance to checkpoint inhibitors. TuHURA has initiated a single randomized placebo-controlled Phase 3 registration trial of IFx-2.0 administered as an adjunctive therapy to Keytruda® (pembrolizumab) compared to Keytruda® plus placebo in first-line treatment for advanced or metastatic Merkel Cell Carcinoma.

In addition to its innate immune agonist product candidates, TuHURA acquired TBS-2025 in its merger with Kineta Inc. on June 30, 2025. TBS-2025 is a VISTA inhibiting mAb moving into Phase 2 development in mutNPM1 r/r AML. In addition, TuHURA is leveraging its Delta Opioid Receptor technology to develop first-in-class, bi-specific antibody drug conjugates and antibody peptide conjugates targeting Myeloid Derived Suppressor Cells to inhibit their immune-suppressing effects on the tumor microenvironment to prevent T cell exhaustion and acquired resistance to checkpoint inhibitors and cellular therapies.
