ADJUSTING DOSAGE FOLLOWING CRS & ICANS REACTIONS IN YOUR PATIENTS
Management of CRS while using TEPKINLY1
95% of CRS events occurred in the first cycle2
Gradea | Recommended Therapy | TEPKINLY Dose Modification |
---|---|---|
Grade 1
| Provide supportive care such as antipyretics and intravenous hydration
For CRS with concurrent ICANS, refer to ICANS tab | Hold TEPKINLY until resolution of CRS event |
Grade 2
| Provide supportive care such as antipyretics and intravenous hydration
For CRS with concurrent ICANS, refer to ICANS tab | Hold TEPKINLY until resolution of CRS event |
Grade 3
| Provide supportive care such as antipyretics and intravenous hydration Anticytokine therapy, tocilizumab,d is recommended If CRS is refractory to dexamethasone and tocilizumab:
For CRS with concurrent ICANS, refer to ICANS tab | Hold TEPKINLY until resolution of CRS event In the event of grade 3 CRS lasting longer than 72 hours, TEPKINLY should be discontinued If more than 2 separate events of grade 3 CRS, even if each event resolved to grade 2 within 72 hours, TEPKINLY should be discontinued |
Grade 4
| Provide supportive care such as antipyretics and intravenous hydration Anticytokine therapy, tocilizumab,d is recommended If CRS is refractory to dexamethasone and tocilizumab:
For CRS with concurrent ICANS, refer to ICANS tab | Permanently discontinue TEPKINLY |
aCRS graded according to ASTCT consensus criteria.
bDexamethasone should be administered at 10-20 mg per day (or equivalent).
cDexamethasone should be administered at 10-20 mg intravenously every 6 hours.
dTocilizumab 8 mg/kg intravenously over 1 hour (not to exceed 800 mg per dose). Repeat tocilizumab after at least 8 hours as needed. Maximum of 2 doses in a 24-hour period.
eLow-flow oxygen is defined as oxygen delivered at <6 L/minute.
fHigh-flow oxygen is defined as oxygen delivered at ≥6 L/minute.

Recommended dose modifications for other adverse reactions1
Gradea | Recommended Therapy | TEPKINLY Dose Modification |
---|---|---|
Grade 1b ICE scorec 7-9b | Treatment with dexamethasoned
For ICANS with concurrent CRS;
| Hold TEPKINLY until resolution of event |
Grade 2b ICE scorec 3-6b | Treatment with dexamethasonef
For ICANS with concurrent CRS:
| Hold TEPKINLY until resolution of event |
Grade 3b ICE scorec 0-2
| Treatment with dexamethasoneg
For ICANS with concurrent CRS:
| Permanently discontinue TEPKINLY |
Grade 4b ICE scoreb,c 0
| Treatment with dexamethasoneg
Consider nonsedating antiseizure medicinal products (eg, levetiracetam) until resolution of ICANS No concurrent CRS:
For ICANS with concurrent CRS:
| Permanently discontinue TEPKINLY |
aICANS graded according to ASTCT ICANS Consensus Grading.
bICANS grade is determined by the most severe event (ICE score, level of consciousness, seizures, motor findings, raised ICP/cerebral oedema) not attributable to any other cause.
cIf patient is arousable and able to perform Immune Effector Cell-Associated Encephalopathy (ICE) Assessment, assess: Orientation (oriented to year, month, city, hospital=4 points); Naming (name 3 objects, eg, point to clock, pen, button=3 points); Following Commands (eg, “show me 2 fingers” or “close your eyes and stick out your tongue”=1 point); Writing (ability to write a standard sentence=1 point); and Attention (count backwards from 100 by ten=1 point). If patient is unarousable and unable to perform ICE Assessment (Grade 4 ICANS)=0 points.
dDexamethasone should be administered at 10 mg intravenously every 12 hours.
eRiegler L, et al (2019).
fDexamethasone 10-20 mg intravenously every 12 hours.
gDexamethasone 10-20 mg intravenously every 6 hours.

I would like to request a meeting with an AbbVie representative.
Explore the subcutaneous dosing schedule for TEPKINLY and important administration tips.
ASTCT=American Society for Transplantation and Cellular Therapy; BiPAP=bilevel positive airway pressure; CPAP=continuous positive airway pressure; CRS=cytokine release syndrome; EEG=electroencephalogram; ICANS=immune effector cell-associated neurotoxicity syndrome; ICE=immune effector cell-associated encephalopathy; ICP=intracranial pressure.
TEPKINLY as monotherapy is indicated for the treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) after two or more lines of systemic therapy.1
