Enhertu: The ADC That Changed Everything
Enhertu redefined what an ADC could achieve. Its expansion from HER2-positive to HER2-low and HER2-ultralow breast cancer populations dramatically increased the addressable patient population. The January 2025 FDA approval for HR-positive, HER2-low/ultralow breast cancer alone expanded the treatable population by an estimated 200,000+ patients in the U.S.
Market Dynamics: $13.5B and Accelerating
The ADC market has entered a sustained growth phase driven by multiple reinforcing factors. New indication approvals are expanding existing product revenue, while a steady stream of new approvals is broadening the overall market. The combination of ADCs with checkpoint inhibitors — exemplified by the Padcev + Keytruda combination showing 49% mortality-risk reduction in urothelial cancer — is creating new treatment paradigms that pull ADCs into earlier lines of therapy.
The competitive landscape is intensifying as major pharma companies position for ADC leadership. Pfizer's $43 billion acquisition of Seagen in 2023 was the defining transaction, giving Pfizer control of both Adcetris and Padcev plus a deep pipeline. AbbVie's acquisition of ImmunoGen (Elahere) and the continued Daiichi Sankyo-AstraZeneca partnership for Enhertu demonstrate that ADC assets command premium valuations.

Pipeline: 200+ Candidates in Development
The ADC clinical pipeline is the most active in oncology, with over 200 candidates in clinical development. Pipeline diversity has expanded dramatically — from traditional hematology and breast cancer targets to solid tumors including NSCLC, ovarian, prostate, and gastrointestinal cancers. Novel targets such as Claudin 18.2 (gastric), B7-H3 (multiple solid tumors), DLL3 (small cell lung cancer), and c-Met (NSCLC) are opening new therapeutic frontiers.
Bispecific ADCs represent the next paradigm shift — single molecules that target two distinct tumor antigens, potentially improving tumor selectivity and overcoming antigen escape resistance. Multiple bispecific ADC candidates have entered clinical trials, combining the targeting advantages of bispecific antibodies with the payload delivery mechanism of ADCs.

Case Study: The Daiichi Sankyo–AstraZeneca ADC Partnership
Daiichi Sankyo × AstraZeneca • Oncology — Antibody-Drug Conjugates
Daiichi Sankyo possessed a breakthrough DXd linker-payload platform powering multiple ADC candidates (Enhertu, Dato-DXd, DS-7300), but needed global commercial scale and oncology development expertise to maximize the platform's potential across geographies and indications.
Structured a 50/50 co-development and co-commercialization agreement (March 2019) covering three ADCs — Enhertu (HER2), Dato-DXd/Datroway (Trop-2), and DS-7300 (B7-H3). AstraZeneca contributed $1.35 billion upfront plus up to $5.6 billion in milestones, gaining access to an ADC engine powering multiple blockbusters.
Enhertu alone generated $3.75 billion in combined 2024 sales. The deal established the co-development model for ADC mega-deals, proving that platform partnerships generate more value than single-asset licenses. BD executives should prioritize platform-level ADC partnerships over individual candidate licenses.
Technology Evolution: Next-Gen ADC Platforms
ADC technology has undergone three generations of evolution. First-generation ADCs (Mylotarg, original Kadcyla) used non-cleavable linkers with limited payloads and suffered from narrow therapeutic windows. Second-generation ADCs (current market leaders) introduced cleavable linkers, site-specific conjugation, and more potent topoisomerase I inhibitor payloads. The third generation now emerging features novel payload classes, higher drug-to-antibody ratios (DAR), conditional activation mechanisms, and dual-payload designs.
Gen 1: Foundational
- Random conjugation (DAR 3-4)
- Maytansine/calicheamicin payloads
- Non-cleavable linkers
- Narrow therapeutic window
- Examples: Mylotarg, Kadcyla
Gen 2: Current Leaders
- Site-specific conjugation (DAR 4-8)
- Topo I/MMAE payloads
- Cleavable linkers with bystander effect
- Improved therapeutic index
- Examples: Enhertu, Padcev, Trodelvy
Gen 3: Emerging
- High-DAR (8-12) with controlled release
- Novel payloads: immune agonists, degraders
- Bispecific targeting antibodies
- Conditional activation (tumor microenvironment)
- Examples: Bispecific ADCs, immune-stimulating ADCs
Traditional Chemo vs ADCs: Strategic Comparison
ADCs are systematically displacing traditional cytotoxic chemotherapy across multiple indications. The Padcev + Keytruda combination demonstrating a 49% mortality-risk reduction versus chemotherapy in first-line urothelial cancer exemplifies this shift. As ADCs move into earlier treatment lines, the strategic implications for portfolio planning are significant.
Traditional Chemotherapy vs ADCs
| Dimension | Conventional Chemotherapy | Antibody-Drug Conjugates |
|---|---|---|
Targeting How the drug reaches cancer cells. | Broad cytotoxic distribution throughout body | Antibody-guided delivery to tumor cells |
Therapeutic Window Balance of efficacy vs side effects. | Narrow; dose-limited by systemic toxicity | Wide; enables use of ultra-potent payloads |
Side Effects Safety and tolerability profile. | Severe systemic toxicity (nausea, neutropenia, hair loss) | Targeted; lower systemic toxicity (ocular, neuropathy) |
Efficacy Clinical outcomes and response. | Declining response rates in later lines | Durable responses even in chemo-refractory patients |
Cost Treatment economics. | $5-15K per treatment cycle (generic available) | $100-250K+ per treatment course (specialty pricing) |
Market Trajectory Commercial and competitive trends. | Declining share; generic competition | $13.5B and growing at 10%+ CAGR; premium pricing |
China's ADC Engine: Out-Licensing Boom
Chinese biotech companies have emerged as prolific ADC innovators, driving a wave of outbound licensing deals to global pharma. China-originated ADC assets are being licensed at increasingly large valuations, reflecting both the quality of science emerging from Chinese R&D and the strategic urgency of global companies to build ADC pipelines.
Key China-to-global ADC deals include Astellas' $1.54 billion deal with Evopoint Biosciences for XNW27011, Roche's expanded deal with MediLink Therapeutics for YL201 ($570M+ near-term), and multiple other transactions in the $200-500 million range. Chinese companies bring advantages in speed of development, cost-effective manufacturing, and willingness to explore novel targets — making China-origin ADC assets attractive in-licensing opportunities for global pharma.
However, the BIOSECURE Act creates complexity for China-originated assets with manufacturing ties to designated companies. BD executives must conduct thorough due diligence on manufacturing supply chains, IP ownership structures, and BIOSECURE compliance pathways when evaluating China-origin ADC in-licensing opportunities.
China ADC Licensing — Due Diligence Framework
- IP landscape: Confirm freedom-to-operate for linker-payload technology in US/EU jurisdictions
- Manufacturing: Assess BIOSECURE exposure — can the asset be manufactured outside China for US government-linked programs?
- Clinical data quality: Ensure Phase I/II data from Chinese sites meets FDA/EMA standards for IND bridging
- Target overlap: Evaluate competitive landscape for the target antigen — many Chinese ADCs target HER2, Trop-2, and Claudin 18.2
- Regulatory pathway: Map China NMPA data packages to US FDA requirements — identify gaps requiring additional studies
BD Strategy & Licensing Opportunities
The ADC licensing environment rewards companies that move decisively. The most valuable assets are platform technologies (linker-payload systems, conjugation chemistry) that can generate multiple clinical candidates, rather than individual ADC products. Companies with manufacturing capabilities and regulatory expertise in ADC development are particularly well-positioned to attract in-licensing partnerships.
In-Licensing Priorities
- Novel targets: ADCs targeting Claudin 18.2, B7-H3, DLL3, and GPRC5D where competition is still manageable
- Platform technologies: Next-gen linker-payload systems enabling higher DAR, conditional activation, or immune-stimulating payloads
- China-origin assets: Early-stage ADCs from Chinese biotechs with differentiated constructs at attractive valuations
- ADC combinations: Data packages supporting ADC + checkpoint inhibitor combinations for earlier-line therapy
Out-Licensing Opportunities
- Regional rights: Ex-US/EU rights for approved or late-stage ADCs in Asia-Pacific and emerging markets
- Payload licensing: Novel cytotoxic or immune-stimulating payloads licensed to multiple ADC developers
- Conjugation IP: Site-specific conjugation technologies applicable across multiple antibody-payload combinations
- CDMO services: Specialized ADC manufacturing capacity — a bottleneck creating partnership opportunities
Conclusion & Strategic Outlook
Antibody-drug conjugates have definitively established themselves as a core pillar of oncology treatment. With 15 approved products, $13.5 billion in annual revenue, and a pipeline of 200+ candidates, the ADC field is entering its most dynamic phase. The convergence of next-generation technologies (bispecific ADCs, immune-stimulating payloads, conditional activation), expansion into earlier treatment lines, and potential applications beyond oncology creates a rich opportunity landscape for BD professionals.
The licensing environment rewards speed and technical sophistication. Platform-level deals (Synaffix, Araris, Tubulis) are commanding billion-dollar valuations, while China-origin assets offer attractive risk-adjusted returns for companies willing to navigate BIOSECURE complexity. The Daiichi Sankyo-AstraZeneca model demonstrates that the highest value creation comes from co-development partnerships on platform technologies, not individual product licenses.
Key 2026 catalysts include Enhertu data in additional tumor types, Padcev + Keytruda regulatory milestones, and multiple Phase III readouts for next-generation ADC candidates targeting novel antigens. Companies that build ADC portfolios now — whether through in-licensing, platform partnerships, or strategic acquisitions — will be best positioned for the $30+ billion market opportunity ahead.
