 Assess patients with a thorough
history and physical examination
 Screen for pre-existing neuropathy
or diabetes mellitus
Before a patient starts
treatment with either
EV or SG … 
•There is a risk of infusion-related reactions
•Although rare, grade 3-4 reactions do occur
– Infusion-site extravasation observed with
EV; ensure adequate venous access
prior to infusion
•Hypersensitivity reactions, ranging from mild
to anaphylaxis, have been seen within 24 h
of SG administration
– Premedicate with an antipyretic and H1
and H2 blockers prior to each infusion
– Have medication and emergency
equipment to treat such reactions ready
for immediate use
•Monitor patients during the infusion and for
≥30 min after completion of infusion
Safety Considerations With ADCs
Peripheral Neuropathy
•May be improved/resolved with a
treatment hold
Hyperglycemia
•Monitor blood glucose in patients with/at
risk for diabetes or hyperglycemia
Ocular Disorders
•Monitor and consider prophylactic
artificial tears for dry eyes and treatment
with ophthalmic topical steroids after an
ophthalmic examination
Neutropenia
•Consider growth factor support
•Dose reduction/hold
Diarrhea
•Educate patients
•Maintain hydration with electrolytes
•Antidiarrheal medications/best
supportive care

Erdafinitib: Understanding Safety Considerations

 Patients ideally undergo testing upon
diagnosis
 Options include specifically testing tumors
for FGFR3 alterations (eg, RT-PCR
companion assay) or more comprehensive
approaches (eg, NGS panels, liquid biopsy)
 All members of the care team have
important roles in educating patients on
the implications of genomic testing
Eligibility for FGFR inhibition requires
testing for genomic alterations 
•FGFR3 inhibitors are associated with
unique AEs
•Oral hygiene is critical; mucositis and
other oral toxicities can be a concern
•Monitor for skin and nail toxicities,
referring to dermatology and podiatry
as needed
•Close monitoring and supportive care
is important
General Guidance on AEs
Associated With FGFR3 Inhibitors
•Erdafitinib also inhibits FGFR signaling
in the proximal renal tubule, impairing
function of the sodium-dependent
phosphate co-transporter
•Dietary phosphate may require
restriction
– Consult a nutrition professional
(eg, registered dietitian, nutritionist)
for individualized dietary planning
– Consider adding a non–calcium-
containing phosphate binder (eg,
sevelamer carbonate)
•Recommended ophthalmologic
examinations
– Monthly for first 4 mo; every 3 mo
thereafter
– At any time for visual symptoms
•For any occurrence of central serous
retinopathy (CSR)/retinal pigment
epithelial detachment (RPED):
– Withhold erdafitinib; discontinue
permanently if symptoms do not
resolve in 4 wk
– Discontinue permanently for
grade 4 CSR/RPED

Patient education must 
focus on the importance of 
prompt recognition and 
management of irAEs
Grade 1
Minimal or no symptoms; diagnostic change only
•In general, immune checkpoint inhibitor therapy should be continued with
close monitoring, with the exception of some neurologic, hematologic, and
cardiac toxicities
Grade 2
Mild to moderate symptoms
•Hold checkpoint inhibitor therapy for most grade 2 toxicities
•Consider resuming immunotherapy when symptoms and/or laboratory
values revert to grade 1 or lower
•Corticosteroids (initial dose of 0.1-1 mg/kg/d of prednisone or equivalent)
may be administered
Grade 3/4
Severe or life-threatening symptoms
Grade 3
•Hold checkpoint inhibitor therapy
•Initiate high-dose corticosteroids (prednisone 1-2 mg/kg/d or
methylprednisolone IV 1-2 mg/kg/d)
•If symptoms do not improve with 48-72 h of high-dose corticosteroids,
infliximab may be offered for some toxicities
•Taper corticosteroids over the course of at least 4-6 wk
•When symptoms and/or laboratory values revert to grade 1 or lower,
rechallenging with immunotherapy may be offered; however, caution is
advised, especially in those patients with early-onset irAEs; dose
adjustments are not recommended
Grade 4
•In general, permanent discontinuation of checkpoint inhibitor therapy is
warranted, with the exception of endocrinopathies that have been
controlled by hormone replacement

Understanding the Impact of Subcutaneous Immune Checkpoint Inhibitors

SC Administration Provides an Alternative With Benefits for Both Patients and Providers
Immune Checkpoint Inhibitors Are Approved Across Many Tumor Types
• IV infusions can be associated with treatment burdens (eg, long
administration times, risk for complications)
• SC approaches will have an impact not only for the patient but also for
healthcare professionals, as it will affect the organization of care
