TuHURA Biosciences Moves Forward with Phase 3 Trial
TuHURA Biosciences, Inc. (NASDAQ: HURA) is making substantial strides in the field of cancer immunotherapy. The company is geared up to launch its Phase 3 accelerated approval trial of IFx-2.0, a promising adjunctive therapy in combination with Keytruda (pembrolizumab), targeting advanced and metastatic Merkel cell carcinoma (MCC).
FDA Approval Unlocks Funding for the Clinical Trial
The recent removal of the partial clinical hold by the U.S. Food and Drug Administration (FDA) signifies a pivotal moment for TuHURA. This decision not only clears the way for the upcoming trial but also triggers the second tranche of funding from the $12.5 million PIPE financing that was announced earlier.
Details of the Upcoming Clinical Trial
The Phase 3 trial will adhere to an agreed Special Protocol Assessment (SPA) with the FDA, focusing on the efficacy of IFx-2.0 when administered weekly for a span of three weeks alongside Keytruda, compared to Keytruda administered with a placebo. The significance of this trial lies in its potential to demonstrate improved Overall Response Rate (ORR), which is critical for the accelerated approval process.
With an enrollment target of approximately 118 participants across 22 to 25 U.S. clinical sites, the study design randomizes participants to receive either Keytruda plus IFx-2.0 or Keytruda plus placebo for a maximum duration of two years, unless disease progression or adverse effects occur. The trial's primary goal is to achieve an ORR, while Progression Free Survival (PFS) serves as a key secondary endpoint. Success in these measures could pave the way for regular approval without necessitating a post-approval confirmatory trial, a common requirement for accelerated approvals.
About TuHURA Biosciences
TuHURA Biosciences stands at the forefront of immuno-oncology innovation. By developing advanced technologies to combat both primary and acquired resistance to cancer therapies, TuHURA aims to enhance treatment effectiveness in patients facing aggressive cancers. The company’s leading product candidate, IFx-2.0, is crafted to enhance the efficacy of checkpoint inhibitors, a critical aspect of cancer treatment.
The anticipated merger with Kineta, Inc. holds further promise. Upon successful completion, TuHURA plans to advance Kineta’s innovative VISTA inhibiting antibody into a randomized Phase 2 trial for patients with NPM1 mutated relapsed/refractory acute myeloid leukemia (AML). This collaboration exemplifies TuHURA's commitment to expanding its portfolio and increasing patient access to advanced treatment options.
Beyond its current pipeline, TuHURA is utilizing its proprietary Delta Opioid Receptor technology. This initiative aims to create first-in-class, bi-specific antibody drug conjugates and peptide conjugates that target Myeloid Derived Suppressor Cells, which play a role in the immune-suppressing tumor microenvironment. This approach is integral to preventing T cell exhaustion and overcoming acquired resistance to both checkpoint inhibitors and cell-based therapies.
