Adjusting for differences involving cohorts in line of therapy (36 of patients had received 5 or extra lines of therapy in the ibrutinib cohort versus only 13 inside the Stockholm cohort–see Table 1) and ECOG status (41 of patients had ECOG 0 in the cohort versus 23 in the Stockholm cohort) had the largest influence on the estimate of your therapy impact on PFS (Table two, Appendix). As adjustment for both characteristics had an opposite effect (suggesting ibrutinib patients to have additional sophisticated disease depending on line of therapy, but much less severe determined by ECOG), this finally leads to an adjusted HR close to the unadjusted outcome.The adjusted PFS HRs for ibrutinib versus individual therapy regimens are depicted in Fig. 3a and ranged in between 0.06 (compared with CD20mAb) and 0.30 (compared with FCR) and were statistically significant in all instances. The greatest distinction involving ibrutinib and also other regimens was observed versus immunotherapy alone and versus CLB (each HR = 0.ten [95 CI 0.06, 0.16; p 0.0001]), and also the smallest was observed when in comparison with chemoimmunotherapy therapies (HR = 0.22 [95 CI 0.14, 0.33; p 0.0001]) (Fig. 3a). The PFS HR for ibrutinib versus the ofatumumab arm from RESONATE (HR = 0.11 [95 CI 0.07, 0.15; p 0.0001]) was comparable for the HR versus the Stockholm cohort (HR = 0.15 [95 CI 0.11, 0.22; p 0.0001]).Ann Hematol (2017) 96:1681691 Fig. 1 Remedies most frequently utilized inside the Stockholm (prior normal of care) cohort, by line of therapy.

Figure 4a represents the HRs for all prognostic baseline covariates from the similar multivariate Cox model according to the pooled data from RESONATE and Stockholm cohorts, which also generated the adjusted HR for ibrutinib versus earlier standard of care reported in Fig. 3a. It illustrates the prognostic value of each baseline characteristic: older age, male gender, Binet C disease stage, poorer ECOG overall performance status and later line of therapy had been all statistically significant independent danger factors for worse outcome on PFS (p 0.05); refractory status was numerically linked with poorer PFS. The interaction effect of treatment with all baseline characteristics was only considerable for age (p = 0.025), sug.
