Rhea-AI Filing Summary

Kyntra Bio reported fourth quarter and full-year 2025 results and highlighted progress in its oncology and rare disease pipeline. The company is running a Phase 2 monotherapy trial of FG-3246 in metastatic castration-resistant prostate cancer, with an interim analysis planned in the second half of 2026, and reported encouraging investigator-sponsored combination data with enzalutamide presented at ASCO meetings.

Kyntra submitted a pivotal Phase 3 protocol for roxadustat in anemia due to lower-risk myelodysplastic syndromes to the FDA and is evaluating whether to advance this program alone or with a partner. Total revenue from continuing operations fell to $6.4 million in 2025 from $29.6 million in 2024, but the net loss from continuing operations narrowed to $58.2 million from $153.1 million, reflecting a restructuring and portfolio shift. The company ended 2025 with $109.4 million in cash, cash equivalents, investments, and accounts receivable and currently expects this to fund operating plans into 2028.

Positive

  • Substantial improvement in continuing operations loss: Net loss from continuing operations shrank to $58.2 million in 2025 from $153.1 million in 2024, reflecting a major reduction in operating burn after the company’s 2025 transformation.
  • Strengthened balance sheet and runway: Cash, cash equivalents, investments, and accounts receivable totaled $109.4 million at December 31, 2025, and management currently expects this to fund operating plans into 2028, providing time to advance key clinical programs.
  • Advancing late-stage and mid-stage pipeline: A pivotal Phase 3 protocol for roxadustat in LR-MDS has been submitted to the FDA, and a Phase 2 monotherapy trial of FG-3246 in metastatic castration-resistant prostate cancer is enrolling, supported by positive investigator-sponsored combination data.

Negative

  • Sharp revenue decline from continuing operations: Total revenue from continuing operations dropped to $6.4 million in 2025 from $29.6 million in 2024, indicating a significantly smaller ongoing commercial and collaboration base after portfolio changes.
  • Business still loss-making on a continuing basis: Despite improvements, Kyntra Bio recorded a net loss from continuing operations of $58.2 million in 2025 and $14.6 million in the fourth quarter, underscoring continuing dependence on external capital sources or future revenue growth over time.

Insights

Kyntra shifts to oncology and MDS focus, improves losses and extends cash runway.

Kyntra Bio is pivoting around two key assets: FG-3246, a CD46-targeted ADC for metastatic castration-resistant prostate cancer, and roxadustat for anemia in lower-risk myelodysplastic syndromes. Phase 2 monotherapy for FG-3246 is enrolling, supported by combination data showing median radiographic progression-free survival of 7.0 months overall and 10.1 months in a defined subgroup.

For roxadustat, the company has Orphan Drug Designation in MDS and has submitted a pivotal Phase 3 protocol to the FDA, aiming to start the trial in the second half of 2026. This adds a late-stage rare disease opportunity alongside oncology, though execution will depend on regulatory feedback and potential partnering.

Financially, revenue from continuing operations declined to $6.4 million from $29.6 million, reflecting divestitures and strategy changes, but the net loss from continuing operations improved to $58.2 million from $153.1 million. Cash, investments, and receivables of $109.4 million are expected to support operations into 2028, giving the company a multiyear window to deliver clinical milestones in FG-3246 and roxadustat.

SAN FRANCISCO, March 16, 2026 (GLOBE NEWSWIRE) -- Kyntra Bio (Nasdaq: KYNB) today reported financial results for the fourth quarter and full year 2025 and provided an update on the company’s recent developments.

“The encouraging results from the investigator-sponsored combination trial of FG-3246 with enzalutamide provide us with valuable insights and reinforce key design elements in our Phase 2 monotherapy study,” said Thane Wettig, Chief Executive Officer of Kyntra Bio. “Our Phase 2 monotherapy trial of FG-3246 is progressing as planned, with interim results expected in the second half of 2026. Additionally, we have submitted the Phase 3 trial protocol for roxadustat for the treatment of anemia in patients with LR-MDS and expect feedback from the FDA shortly, with the intention to start a Phase 3 trial in the second half of 2026. With our successful transformation in 2025, we are well-positioned to execute our strategic plan in 2026 and anticipate an exciting year ahead.”

 

Key Highlights of Fourth Quarter 2025, Recent Developments, and Upcoming Milestones

 

FG-3246 (CD46 Targeting ADC) and FG-3180 (CD46 Targeting PET Imaging Agent)

Phase 2 monotherapy trial of FG-3246, a potential first-in-class ADC targeting CD46, in mCRPC is actively enrolling and remains on track for interim analysis in the second half of 2026
Topline results from the investigator-sponsored Phase 1b/2 study, conducted by UCSF, of FG-3246 in combination with enzalutamide in patients with mCRPC were presented at ASCO GU 2026
o
FG-3246 and enzalutamide combination therapy, in biomarker unselected patients with androgen receptor pathway inhibitor (ARPI)-treated, taxane-naïve mCRPC, led to a median radiographic progression free survival (rPFS) of 7.0 months in the overall study cohort, with median rPFS of 10.1 months observed in patients who progressed on only one prior ARPI
o
Higher tumor uptake of FG-3180 was numerically associated with PSA50 response (nominal p=0.053), highlighting its potential as a biomarker for patient selection
o
Combination therapy had a similar safety and exposure profile to the previous FG-3246 Phase 1 monotherapy trial
o
Results further validate key FG-3246 Phase 2 monotherapy design elements, most importantly the inclusion of patients who have progressed on only one prior ARPI and integration of baseline FG-3180 PET for all enrolled patients

Roxadustat

Granted Orphan Drug Designation from the FDA for the treatment of MDS.
Submitted the pivotal Phase 3 clinical trial protocol for roxadustat for the treatment of anemia in patients with LR-MDS and high transfusion burden to the U.S. Food and Drug Administration.
Company is currently exploring the opportunity to develop roxadustat internally or with a strategic partner, with the goal of starting the Phase 3 trial in the second half of 2026.

About FG-3246 and FG-3180

FG-3246 (FOR46) is a potential first-in-class fully human antibody-drug conjugate (ADC), exclusively in-licensed from Fortis Therapeutics, and is being developed by Kyntra Bio for metastatic castration-resistant prostate cancer and potentially other tumor types. FG-3246 binds to an epitope of CD46, a cell receptor target, that induces internalization upon antibody binding, is present at high levels in prostate cancer and other tumor types and demonstrates very limited expression in most normal tissues. FG-3246 is comprised of an anti-CD46 antibody, YS5, linked to the anti-mitotic agent, MMAE, which is a clinically and commercially validated ADC payload. FG-3246 has demonstrated anti-tumor activity in both preclinical and clinical studies. FG-3180 is a companion diagnostic PET imaging agent, using the same CD46-targeting antibody together with an 89Zr tracker. To date, FG-3180 demonstrated specific uptake in CD46 positive tumors and is currently being evaluated as a biomarker for its potential to inform patient selection.

 

About Roxadustat

Roxadustat, an oral medication, is the first in a new class of medicines comprising HIF-PH inhibitors that promote erythropoiesis, or red blood cell production, through increased endogenous production of erythropoietin, improved iron absorption and mobilization, and downregulation of hepcidin.

 

Roxadustat is approved in Europe, Japan, China, and numerous other countries for the treatment of anemia of CKD in adult patients on dialysis (DD) and not on dialysis (NDD). Kyntra Bio has the sole rights to roxadustat in the United States, Canada, Mexico, and in all markets not held by AstraZeneca or licensed to Astellas. Astellas and Kyntra Bio are collaborating on the commercialization of roxadustat for the treatment of anemia in territories including Japan, Europe, Turkey, Russia, and the Commonwealth of Independent States, the Middle East, and South Africa.
