Samsung Bioepis and NIPRO Forge Strategic Alliance to Reshape Japan's Biosimilar Landscape
INCHEON, South Korea — Samsung Bioepis announced on June 8 a comprehensive partnership with NIPRO Corporation to commercialize multiple biosimilars in the world's third-largest pharmaceutical market.
The deal, centering on Samsung's ustekinumab biosimilar candidate SB17, represents a calculated push into a market historically resistant to biologic copycats but now increasingly receptive amid government-led cost-cutting initiatives.

"Japan's Biosimilar Catch-Up Window" Opens as Healthcare Costs Mount
Japan's healthcare system finds itself at a critical inflection point. With ethical drug sales reaching ¥10.8 trillion in fiscal year 2024—a modest 0.6% increase—biologic medications comprise an increasingly disproportionate share of national pharmaceutical expenditure.
Unlike the European Union, where biosimilars have captured over 30% market share in some categories, Japan's adoption has languished in single digits despite a decade of availability. This gap appears ready to close, as recent regulatory changes have shortened clinical bridging requirements and created what industry observers describe as a "pipeline bulge."
"The Japanese government is clearly signaling its support for biosimilars through both carrot and stick," notes a healthcare policy analyst familiar with Japan's pricing mechanics. "Hospital incentives combined with price maintenance premium claw-backs have already accelerated oncology biosimilar adoption by 1-2 percentage points monthly."
Ustekinumab: The Crown Jewel in a Multi-Asset Strategy
At the partnership's core sits SB17, Samsung's biosimilar version of Johnson & Johnson's blockbuster Stelara (ustekinumab), which generated $10.4 billion globally in 2024. The immunology therapy, used primarily for psoriasis, psoriatic arthritis, and Crohn's disease, represents a significant commercial opportunity in Japan where annual sales are estimated at approximately ¥115 billion.
The timing appears strategically calculated—Japan's National Health Insurance already slashed Stelara's price by 40.8% in April 2025, a move widely interpreted as preparing the market for biosimilar competition.
Samsung Bioepis' clinical position appears robust, with head-to-head Phase 3 trials meeting all endpoints through 52 weeks, including seamless switching data. The company expects FDA and European regulatory decisions in the second half of 2025, with Canadian authorities having already granted approval in August 2024.
Competitive Chess: Why NIPRO, Why Now?
NIPRO, primarily known for medical devices and dialysis solutions, might seem an unexpected partner for Samsung's biologics push. However, the Osaka-based company brings substantial advantages to the partnership, including a 500-strong sales force with established relationships in Japan's Diagnosis Procedure Combination (DPC) hospitals—the very institutions where biosimilar adoption decisions are typically concentrated.
For NIPRO, biosimilars offer compelling financial diversification. With its pharmaceutical segment comprising less than 20% of its ¥645 billion annual revenue and generating sub-5% operating margins, the high-margin biosimilar opportunity could meaningfully transform the company's profit profile.
"This strategic move places NIPRO in position to potentially capture 20% market share by fiscal year 2028," suggests a pharmaceutical equity analyst who requested anonymity. "Such penetration could generate approximately ¥15 billion in revenue for the partnership, with Samsung Bioepis receiving roughly ¥7.5 billion annually—equivalent to about 5% of its 2024 revenue."
Beyond Ustekinumab: Platform Partnership Potential
While SB17 headlines the announcement, industry experts note Samsung Bioepis possesses six additional Japan-ready molecules that could eventually fall under the partnership's umbrella. These include biosimilars of infliximab, etanercept, adalimumab, ranibizumab, eculizumab, and aflibercept—spanning immunology, ophthalmology, and rare disease therapeutic areas.
"What we're potentially witnessing is the foundation of a broad co-marketing platform, not merely a single-product transaction," observes a biotechnology consultant specializing in Asian healthcare markets. "The expanded portfolio approach would allow both companies to amortize market entry costs across multiple revenue streams."
"Execution Risk is Real" – Challenges Ahead
Despite the strategic rationale, the partnership faces significant hurdles. Japan's biosimilar market remains structurally different from Western counterparts, with physician preference driving adoption in the absence of automatic substitution policies.
NIPRO's inexperience with complex biologics represents another uncertainty. While its hospital relationships run deep, the company has never marketed products requiring the specialized clinical messaging and handling characteristics of monoclonal antibodies.
The competitive landscape for ustekinumab biosimilars in Japan is also intensifying. Fuji/Alvotech's AVT04 gained approval in September 2023, while Biocon/Yoshindo secured authorization in January 2025. Celltrion's CT-P43 candidate remains in late-stage development.
Currency volatility presents an additional challenge, potentially compressing won-denominated margins for Samsung Bioepis, though industry sources suggest the company typically includes foreign exchange pass-through clauses in its supply agreements.
Investment Implications: Hidden Value and Repricing Potential
For investors watching this development, the implications differ markedly between the two companies. Samsung Biologics, which now owns 80% of Samsung Bioepis, likely won't see material financial impact from the partnership in 2025-2026. However, the deal validates the company's multi-partner commercialization strategy and establishes a beachhead in Japan's expanding biosimilar market, estimated to exceed ¥400 billion.
NIPRO's valuation dynamics appear more immediately compelling. Trading at approximately 0.8 times fiscal year 2026 estimated enterprise value-to-sales—well below the 1.4-1.8 multiple commanded by biosimilar peers like Fuji Pharma and Nichi-Iko—NIPRO shares appear to price in little to no success from the partnership.
"The market has yet to incorporate meaningful biosimilar revenue into NIPRO's forecasts," explains a Tokyo-based healthcare analyst. "If management executes effectively, biosimilars could potentially enhance the group's operating margin by more than 150 basis points within five years."
Looking Ahead: Catalysts on the Horizon
Several near-term milestones will shape the partnership's trajectory. FDA and European regulatory decisions on SB17 in the third quarter of 2025 will confirm manufacturing robustness and likely accelerate Japanese regulatory filing. The National Health Insurance listing of Biocon/Yoshindo's ustekinumab biosimilar in early 2026 will establish benchmark pricing and inform NIPRO's commercial strategy.
Japan's fiscal year 2026 off-year price revision could further reduce Stelara's reference price, potentially widening the competitive gap for biosimilars. Additionally, Samsung Biologics' Plant 5 completion in 2026-2027 will add 360,000 liters of manufacturing capacity, lowering production costs and potentially enhancing partnership economics.
As Japan enters what industry observers call its "biosimilar catch-up window" between 2026 and 2029, early market entrants like the Samsung-NIPRO alliance stand positioned to capture premium economics before reference price resets normalize margins. For now, both companies have placed their strategic bets on Japan's biological future—with patients, healthcare systems, and potentially shareholders poised to benefit.
