Chapter 01 Β· The Challenge
From Blunt Force Chemotherapy
to Targeted Biological Missiles
🎯

Targeted Chemotherapy

Conventional chemo broadly targets all rapidly dividing cells. ADCs chemically link a monoclonal antibody to a cytotoxic payload β€” delivering lethal precision directly to tumor cells.

πŸ“ˆ

Superior Survival Outcomes

Meta-analyses show ADCs deliver longer Overall Survival and Progression-Free Survival vs. standard chemotherapy regimens β€” with no increase in overall toxicity.

🧩

15 Approved. 200+ in Development.

From the first FDA approval in 2000 to 15 approved therapies by 2022, the ADC pipeline has become the defining frontier of precision oncology.

The ADC market grew 4,378% from Q1 2015 to Q4 2025. Every day without granular claims intelligence means navigating the fastest-evolving drug class in oncology history β€” blindfolded.

Commercial consolidation β€” Pfizer/Seagen, AstraZeneca/Daiichi, AbbVie, and others drive claim volume as approvals and M&A reshape the landscape. The lines show how each manufacturer's share of ADC claims has evolved quarter by quarter.

2000
First ADC approved. Mylotarg (gemtuzumab ozogamicin) marks the class launch β€” Paul Ehrlich's "magic bullets" arrive in the clinic.
2019–21
Enhertu & Padcev approvals. HER2-directed and urothelial breakthroughs accelerate commercial adoption and plan formulary access.
Dec 2023
Pfizer acquires Seagen for $43B. ADCs enter the strategic core of Big Pharma. Claims volume reflects the expanded commercial footprint.
Jan 2025
Enhertu HER2-low/ultralow approval. $2,446M U.S. FY2025 in-market sales (+32% YoY); AstraZeneca U.S. product revenue from Enhertu $1,176M. Eligible patient population expands dramatically into HR+ breast cancer.

The signal: Manufacturer claim share shifts in the same quarter as approvals and acquisitions β€” IMX data reflects commercial execution before earnings and public reports.

oncology has been missing.

IMX aggregates, normalizes, and delivers U.S. pharmaceutical claims at a depth no other provider matches β€” anonymized zip-code-level, claim-by-claim, day-by-day, segmented by ADC agent, payer, and patient demographics.

Enhertu's trajectory is the defining signal. The Phase III DESTINY-Breast06 trial showed median PFS >1 year and a 36% reduction in disease progression or death vs. chemotherapy (ORR: 62.6% vs. 34.4%). The Jan 27, 2025 FDA approval for HER2-low/ ultralow breast cancer expanded the eligible population dramatically β€” visible in claims data the same quarter. AstraZeneca reported $1,176M U.S. product revenue from Enhertu in FY2025 ($2,446M total U.S. in-market; +32% YoY).

Capability 04 Β· Manufacturer & Commercial Intelligence
Who holds share in ADC therapy
reflects M&A and commercial execution.

Pfizer's $43B Seagen acquisition, AbbVie's ImmunoGen deal, and AstraZeneca/Daiichi's Enhertu dominance are reshaping the landscape. IMX tracks manufacturer claim share and spend quarter by quarter β€” so you see consolidation in real-world data first.

The signal isn't the level β€” it's the change. When a manufacturer's share moves after an approval or acquisition, IMX sees it the same quarter. Real-world claims intelligence ahead of earnings and public reports.

Capability 05 Β· Payer Mix Intelligence
Medicare dominates ADC spend β€”
but the shift is where the signal lives.

ADC patients skew older β€” Medicare is the dominant payer. Commercial, Medicaid, and government coverage shifts reveal access policy changes before they appear in public reports. IMX tracks payment type mix by quarter from oncology claims.

The signal isn't the level β€” it's the change. When Medicare share compresses a point or two day-over-day, formulary access is expanding. IMX sees it first.

Capability 05 Β· Charge Profile
Per-claim charge distribution β€”
percentiles and mean

High-cost oncology ADC therapies produce a wide spread of charge amounts per claim. The interquartile band (P25–P75) captures where half of claims sit; the median is the midpoint, while the mean reflects the upward pull of high-cost tail claims. The scale runs from zero to a headroom above the upper percentiles and mean.

Why it matters: Benchmarking access programs, benefit design, and out-of-pocket exposure starts with the shape of the claim distribution β€” not just averages.

1940s Cohort Dominates

The 1940s birth decade leads β€” consistent with ADC use concentrated in breast cancer and urothelial cancer patient populations. Younger cohort penetration is the key expansion thesis.

⚑

Female-Dominant β€” For Now

Breast cancer ADC use drives the 62.3% female skew. As urothelial, lung, and gastric indications expand (Padcev, Enhertu NSCLC, gastric HER2+), the gender split will rebalance β€” trackable in IMX demographics before analyst models update.

Why it matters: As Enhertu's HER2-low indication expands the eligible population, demographic shifts are the earliest signal of real-world adoption breadth.

Capability 06 Β· Clinical Context

πŸ“‹

Claims follow the coding

Chemotherapy and immunotherapy encounter codes often lead volume; oncology-specific neoplasm codes reflect tumor site and stage of care. IMX surfaces the full diagnosis distribution behind ADC utilization β€” not just drug names.

Why it matters: Labeling and prior-authorization narratives tie to these codes; shifts here precede shifts in prescribing and access.
