RWE Multivariate Analyses

Hi Jennifer - Under the Guidance documents pertaining to KM Analyses (Provision 8 ) and/or Real World Evidence (s1.4), would PAAB accept retrospective studies that use multivariate analyses to identify prognostic factors associated with Overall Survival?
Hello @alee
Provision 8 of the Guidance Document for Claims Based on Kaplan Meier Analysis does not apply to retrospective studies. The Guidance on Real-World Evidence/Data is intended for RWE/D and does not apply to (Kaplan-Meier analyses in) randomized, controlled trials. The use of multivariate analyses to identify prognostic factors associated with overall survival pertaining to a drug product may provide insights for future investigation but it also creates implications for subgroups with specific patient/disease characteristics that would not be acceptable in the absence of pre-planned evaluation of these subgroups (s. 1.4 of the Guidance on Real-World Evidence/Data for RWE/D and s. 3.1.1 of the PAAB Code for randomized, controlled trials).
