Ibrutinib
The pill that ended chemotherapy for most CLL. It blocks the survival signal B cells depend on, and it was the first drug to beat chemoimmunotherapy in nearly every CLL setting.
Approved 2014 (relapsed CLL, RESONATE), 2016 (frontline, RESONATE-2), and with venetoclax as fixed-duration therapy (GLOW, CAPTIVATE; EU 2022). Also mantle cell lymphoma (withdrawn in the US 2023), Waldenström, marginal zone (withdrawn), and chronic GVHD. Off-target inhibition of EGFR, TEC, and CSK causes atrial fibrillation (~10-16%), hypertension, bleeding, and arthralgia; head-to-head trials (ELEVATE-RR, ALPINE) showed acalabrutinib and zanubrutinib are better tolerated, and zanubrutinib more effective, so ibrutinib is now second choice where alternatives exist.

- Route
- Oral
- Schedule
- 420 mg once daily continuously until progression (CLL); 560 mg in MCL
- Monitoring
- Atrial fibrillation, hypertension, bleeding (hold around surgery), infections, cytopenias

- Medicare
- Part D (self-administered)
Oral, self-administered, so it is a Part D drug: covered through a stand-alone Part D plan or Medicare Advantage drug benefit, usually on the specialty tier with 25 to 33% coinsurance until the annual cap ($2,000 in 2025, $2,100 in 2026). Imbruvica was in the first group of ten drugs negotiated under the Inflation Reduction Act: the Medicare maximum fair price of $9,319 per 30-day supply took effect 1 January 2026, a 38% cut from the 2023 list price.
- Commercial insurance
- covered with prior authorisation
Covered for FDA-labelled and NCCN-listed uses, but almost always behind prior authorisation confirming diagnosis, biomarker and line of therapy; dispensed through a specialty pharmacy. Several PBMs now prefer acalabrutinib or zanubrutinib over ibrutinib for CLL on the basis of head-to-head trials.
- List price
- $14,934 per 30-day supply, 2023 list price; negotiated Medicare price $9,319 from 2026

Part D out-of-pocket capped at $2,000 (2025) / $2,100 (2026). Medicare patients cannot use manufacturer co-pay cards; charity funds (PAN, HealthWell, CancerCare) and the Extra Help subsidy are the routes.

Landmark trials in OnCo
ELEVATE-TN put a more selective BTK inhibitor into first-line CLL and, with the head-to-head ELEVATE-RR trial, showed it is as effective as ibrutinib with fewer cardiac side effects. Continuous acalabrutinib became one of the two main front-line options alongside fixed-duration venetoclax combinations. The trade-off is indefinite therapy and cost versus a time-limited course.
ZUMA-2 gave patients with BTK-inhibitor-refractory mantle cell lymphoma, who previously had a median survival under a year, a therapy with durable remissions in a substantial fraction. Brexu-cel is now standard after BTK inhibitor failure and CAR-T is being tested earlier in the disease. Neurotoxicity rates are higher than in other lymphoma CAR-T trials.
