Injury-induced HO and FOP mouse models: BMP-2 implant, ALK2Q207D and ALK2R206H transgenic mice
“Proof of concept in vivo studies with palovarotene were conducted in various injury-induced heterotopic ossification (HO) and FOP mice models, including BMP-2 implant, transgenic mice expressing constitutively active ALK2Q207D mutant and the human relevant ALK2R206H mutation (Shimono et al. 2011; Chakkalakal et al. 2012; Chakkalakal et al. 2016).”
Not reported in the public reviews. Reviewers summarise selectively, so this usually means it wasn't discussed publicly, not that it wasn't studied.
Reviewer's view of the efficacy data
Supports mechanism, but limited as confirmatory evidence of effectiveness due to species differences and study design
“Nevertheless, the utility of the nonclinical data to provide confirmatory evidence of clinical effectiveness on its own is limited by several factors, including species-specific differences and study design issues (Table 5).”
