CAR-T & cell therapy

CAR-T toxicity is a clock, not a checklist.

Cytokine release syndrome and neurotoxicity unfold in hours, chain of identity never stops mattering, and follow-up runs for years. We bring physicians who have carried a CD19 CAR-T through BLA — to your dose-escalation design, your signal definitions, and your safety review.

Why this modality is different

Four things that don't behave like a small molecule

The toxicity window is measured in hours

CRS and ICANS can escalate within hours of infusion — a review cadence built for weekly safety batches misses the window entirely.

Chain of identity never stops mattering

From leukapheresis through manufacturing to infusion, the product is the patient's own cells — an identity error is a patient-safety event, not a paperwork error.

Follow-up runs for years

Long-term follow-up for genetically modified cell products extends well past the trial's primary endpoint — the safety obligation doesn't end at database lock.

Site readiness is part of the safety plan

Sites need ICU-level escalation pathways in place before the first patient is dosed — not discovered during the first CRS event.

Where programs stumble

Four recurring failure points

Design

Dose-escalation designs borrowed from small-molecule oncology don't fit a product with a delayed, evolving exposure curve.

Safety

CRS/ICANS grading criteria left ambiguous until the first event forces an inconsistent, retrospective call.

Regulatory

RMAT and expedited-pathway strategy started too late to shape the pivotal trial design it was meant to inform.

Operational

Site activation outpaces site readiness — a center added for enrollment speed without the escalation pathway a CRS event requires.

Expert-in-the-loop roles by phase

Where the judgment sits, stage by stage

Pre-IND

Dose-escalation design and CRS/ICANS signal definitions, set before protocol lock.

Start-up

Site readiness review — escalation pathway and ICU access confirmed before activation.

Conduct

Named physician adjudicates every CRS/ICANS-graded event, on the clock the toxicity actually runs on.

Post-market

Long-term follow-up design and signal management across the multi-year observation period.

Frequently asked

Questions CAR-T programs ask us

Do you review CRS/ICANS events on the clock they actually happen on?

Yes — Continuous Medical Oversight is built for same-day, not same-week, adjudication, with the named reviewer's decision documented as it happens.

Can you help with site readiness, not just protocol design?

Yes — site-readiness review, including escalation-pathway confirmation, is part of our start-up-phase expert-in-the-loop role.

Is this specific to CD19 CAR-T, or does it extend to other targets?

Our named CAR-T experience is CD19-specific; the underlying safety-governance discipline — signal definitions, documented adjudication, audit trail — applies across CAR-T targets and is scoped to your program on a call.
