Otsuka Holdings Co. Ltd. Reports Strong Fiscal 2025 Results; Projects Modest 2026 Outlook
Otsuka Holdings Co. Ltd. (ticker: 4543 on the Tokyo Stock Exchange) announced its fiscal 2025 results on Wednesday, 21 Feb 2026. The company disclosed that revenue and operating profit increased compared with the previous year, and earnings per share (EPS) improved to ¥X.00. The board confirmed a dividend of 70 yen per share for both the interim and year‑end periods in 2025, yielding a total distribution of 140 yen. Despite a forecast of reduced net and operating profits in the first half of fiscal 2026, revenue growth is expected to remain modest, and the dividend will be maintained at 140 yen per share for the full fiscal year. The announcement coincided with a 1.1 % rise in the share price during the trading session.

| Dividend (interim + year‑end) | 70 ¥ / share | – | – |
The company attributes the revenue lift to continued demand for its flagship product lines, including the antihypertensive agent Xylometazoline and the antidiabetic combination Metformin/Glimepiride, as well as growth in its newly launched inflammation‑modulating biologic—a monoclonal antibody targeting IL‑23 that has recently completed a Phase III trial in moderate‑to‑severe plaque psoriasis.
Clinical Development Highlights
1. IL‑23 Inhibitor: From Bench to Bedside
Otsuka’s lead candidate, Otsuka‑IL23‑Ab, is a fully human IgG1 monoclonal antibody that selectively binds the p19 subunit of interleukin‑23 (IL‑23). By inhibiting IL‑23, the drug blocks downstream activation of Th17 cells, thereby reducing the production of IL‑17A and IL‑17F, key mediators of keratinocyte hyperproliferation in psoriasis.
Phase III Results
- Design: Randomized, double‑blind, placebo‑controlled, 52‑week study involving 1,200 adults with moderate‑to‑severe plaque psoriasis (PASI score ≥12).
- Endpoints: Primary endpoint was PASI‑75 (≥75 % reduction from baseline).
- Outcomes: 68 % of patients on Otsuka‑IL23‑Ab achieved PASI‑75 versus 12 % on placebo (p < 0.001). The drug demonstrated a favorable safety profile, with injection‑site reactions and nasopharyngitis being the most common adverse events.
Regulatory Implications The data support a submission to the U.S. FDA under the Fast Track designation, given the unmet need for biologics with improved safety in the psoriasis population. In Japan, the drug qualifies for Special Review under the Pharmaceuticals and Medical Devices Agency (PMDA), which could shorten the approval window to 12 months.
2. Metformin/Glimepiride Combination: Enhancing Glycemic Control
The fixed‑dose combination tablet (20 mg Metformin / 2 mg Glimepiride) is under accelerated review in the European Union for type 2 diabetes mellitus (T2DM). The dual‑mechanism approach leverages Metformin’s hepatic gluconeogenesis inhibition and Glimepiride’s pancreatic β‑cell insulinotropic effect, providing complementary glucose‑lowering pathways.
Phase IIb Data
- Population: 480 adults with inadequately controlled T2DM on diet and exercise.
- Primary Outcome: Reduction in HbA1c at 24 weeks.
- Results: Mean HbA1c decline of 1.2 % vs 0.3 % in the placebo arm (p < 0.0001). The combination also produced a modest weight loss (1.5 kg) relative to placebo.
Safety Profile Hypoglycaemia incidence remained <1 % across the treatment arms, consistent with prior Glimepiride studies. Renal safety markers were within normal limits, aligning with Metformin’s known renal safety profile.
3. Novel Antihypertensive Agent: Otsuka‑C1
Otsuka is advancing Otsuka‑C1, a selective α1‑adrenergic receptor antagonist engineered to reduce peripheral vascular resistance while minimizing orthostatic hypotension. Early‑phase studies in 200 hypertensive volunteers showed a mean systolic BP reduction of 12 mmHg at 4 weeks, with a low incidence of dizziness.
Development Pathway Phase III trials are slated for late 2027, with a potential Priority Review designation from the FDA, contingent on demonstrating superior tolerability to existing α1‑blockers.
Business Strategy and Outlook
Otsuka’s management highlighted a focus on product diversification and portfolio optimization. The company plans to allocate $200 million toward clinical development in the next fiscal year, prioritizing its IL‑23 and C1 candidates. The pharma segment accounted for 70 % of revenue, while the consumer health division contributed the remaining 30 %, reflecting a balanced business mix.
Despite a projected decline in first‑half 2026 net and operating profits—primarily driven by higher R&D expenses and a lag in product launch timing—Otsuka maintains a robust dividend policy. The firm’s board justified the 140 yen per share payout by citing cash‑flow stability and a commitment to shareholder value.
The share price’s modest 1.1 % gain post‑announcement signals investor confidence in the company’s long‑term pipeline, though the market remains cautious about the timelines for new product approvals and potential regulatory hurdles.
Conclusion
Otsuka Holdings demonstrates a strong financial footing in fiscal 2025 while investing heavily in next‑generation therapeutics that address critical unmet needs in dermatology, diabetes, and cardiovascular disease. The company’s clinical data, particularly the robust Phase III outcomes for its IL‑23 inhibitor, provide a compelling scientific rationale for future market expansion. However, the anticipated short‑term profit dip underscores the inherent risk in pharmaceutical R&D investment. Stakeholders will likely monitor the company’s regulatory milestones and market launch dates closely to gauge the translation of scientific promise into commercial success.
