Safety of subcutaneous and sublingual immunotherapy with allergoids in children: a real-life pharmacovigilance study

Immunotherapy. 2024 Jan;16(1):43-53. doi: 10.2217/imt-2023-0126. Epub 2023 Nov 29.

Abstract

Aims: Allergen-specific immunotherapy uses a sublingual (sublingual immunotherapy [SLIT]) or subcutaneous (subcutaneous immunotherapy [SCIT]) route. This pharmacovigilance study aimed to determine the number and type of adverse drug reactions (ADRs) for SLIT and SCIT using carbamylated monomeric allergoids (CMAs) in children. Materials & methods: This pharmacovigilance study analyzed real-world post-marketing reports collected from a safety database of Lais sublingual tablets and injective Lais-in, containing CMAs for over 10 years. Results & conclusion: From January 2009 to September 2022, 26,107 doses of Lais-in were administered in children; only two nonserious related ADRs (incidence: 0.000077%) were reported. Regarding SLIT, the results showed only 12 spontaneous nonserious ADR reports (incidence: 0.000004%). These data showed the excellent safety profile of both SLIT and SCIT CMAs.

Plain language summary

The cure for allergic people is named allergen-specific immunotherapy (AIT). Recently, AIT uses new substances named allergoids. This study has shown that AIT with allergoids is very safe.
