Objective: To determine safety of intramuscular botulinum toxin A (BoNT-A) injections to reduce spasticity and improve care and comfort of nonambulatory children with cerebral palsy (CP).
Methods: Nonambulatory children with CP were randomly allocated to receive either BoNT-A (n = 23) or sham procedure (n = 18) in Cycle 1. In Cycle 2, the BoNT-A group received a second episode of BoNT-A (n = 20) and sham group received their first episode of BoNT-A (n = 17). A pediatric rehabilitation specialist masked to group allocation graded each adverse event (AE) according to system, severity (mild, moderate, serious, sentinel) and causality (unlikely/unrelated; possible; probable/definite).
Results: There was no difference for all moderate/serious AEs between the BoNT-A and sham/control groups in either Cycle 1 (incident rate ratio = 1.30, 95% confidence interval = 0.43-4.00; P = .64) or Cycle 2 (incident rate ratio = 0.72, 95% confidence interval = 0.30-1.75; P = .47). In Cycle 2, 1 serious, 3 moderate (single-episode group), and 24 mild (single-episode group n = 10; 2 episode group n = 14) AEs were probably/definitely related to BoNT-A.
Conclusions: Children receiving BoNT-A were at no greater risk of moderate/serious AEs compared with a sham control procedure. There was no increased risk of moderate/serious AEs between one and two episodes of BoNT-A.

Therapeutic reversal of immune tolerance following immune checkpoint inhibitors (ICPI) administration, has proven effective in prolonging survival of patients with a variety of solid and liquid tumors, often however at the expenses of discrete toxicities known as immune-related adverse events (AEs). Such reactions result from activation of the immune system and often present with generalized symptoms including fatigue or fever and, in some patients, may cause organ-specific damage. Skin, gut, endocrine, lung and musculoskeletal are the most frequent targets of ICPI toxicity whereas, cardiovascular, hematologic, renal, neurologic and ophthalmologic AEs occur much less frequently.
