The less favourable pre-treatment control in the cinacalcet group than in the AVDs groups was probably due to the secondary introduction of cinacalcet in those patients resistant to AVDs treatment&#46;

as outlined above&#44; this is possibly the first study to describe in detail non-persistence to sHPT treatments and the evolution of laboratory parameters post-discontinuation&#46; The greater observed persistence to cinacalcet compared to AVDs might relate to clinician preference or the lack of a suitable alternative in patients uncontrolled on AVDs treatment alone&#46; Laboratory biochemistry post-discontinuation largely mirrored that observed for initiation and differed by treatment modality&#58; whilst iPTH increased for all three treatment groups&#44; calcium and phosphate decreased for calcitriol-alfa and paricalcitol patients and increased for cinacalcet patients&#46; When an alternative prescription-coverage threshold definition for discontinuation was applied&#44; non-persistence rates increased for all three treatment groups and laboratory trajectories were more conservative&#46;

or undesirable decreases in calcium levels &#40;with cinacalcet&#41;&#46; Discontinuation may also be driven by laboratory goal-attainment&#44; suggesting that some clinicians do not view sHPT as a long-term chronic disorder requiring continuous therapy&#46; Most initial paricalcitol prescriptions were administered intravenously&#44; affording a greater clinical influence on treatment decisions for this group&#46; Nevertheless&#44; the pattern of paricalcitol non-persistence &#40;main definition&#41;

biochemistry and treatment initiation&#47;discontinuation and could explain&#44; to an extent&#44; the clinical differences observed between the treatment groups&#46; Similarly&#44; we focused on total treatment populations when sub-group analyses might have been more revealing&#46; For example&#44; the different prescribing pattern in the Iberian Peninsula &#12287; especially with regard to cinacalcet &#12287; might provide insights into biochemical control which could inform healthcare decision-making by clinicians&#44;

more patients initiated &#12287; as evidenced by prescriptions &#12287; calcitriol-alfa than paricalcitol&#44; with fewest cinacalcet initiations observed&#46; Major geographical prescribing practice differences were observed&#44; reflecting drug reimbursement policies and the availability&#47;application of national and international guidelines&#46; Physician and centre habits might also influence the observed baseline differences in sHPT treatment&#44;

this was not the case for control of serum calcium and phosphate&#44; which was more often outside KDOQI target ranges &#40;and to some extent also outside KDIGO ranges&#41; in AVD-treated patients&#46; The less favourable pre-treatment control in the cinacalcet group than in the AVDs groups was probably due to the secondary introduction of cinacalcet in those patients resistant to AVDs treatment&#46; Attainment of all three mineral metabolism targets was poor&#44; even with treatment&#46; This is a near-universal observation&#44; reflecting the real-life challenges in this regard&#44; where correcting one parameter often represents a trade-off against control of another&#46;</p><p id="par0170" class="elsevierStylePara elsevierViewall">Whilst post-initiation laboratory trajectories have been described previously&#44; as outlined above&#44; this is possibly the first study to describe in detail non-persistence to sHPT treatments and the evolution of laboratory parameters post-discontinuation&#46; The greater observed persistence to cinacalcet compared to AVDs might relate to clinician preference or the lack of a suitable alternative in patients uncontrolled on AVDs treatment alone&#46; Laboratory biochemistry post-discontinuation largely mirrored that observed for initiation and differed by treatment modality&#58; whilst iPTH increased for all three treatment groups&#44; calcium and phosphate decreased for calcitriol-alfa and paricalcitol patients and increased for cinacalcet patients&#46; When an alternative prescription-coverage threshold definition for discontinuation was applied&#44; non-persistence rates increased for all three treatment groups and laboratory trajectories were more conservative&#46; We hypothesise that our main definition may represent definitive treatment drop-outs which occur infrequently&#44; whilst our sensitivity definition captures treatment adaptations which occur more frequently&#46;</p><p id="par0175" class="elsevierStylePara elsevierViewall">Drug discontinuation may be patient- or physician-led and it was impossible to determine in this study which were patient decisions&#44; based on drug intolerance or pill fatigue&#44; and which were medical decisions based on overcorrection of PTH levels &#40;all treatment groups&#41;&#44; undesirable increases in calcium and phosphate levels &#40;mostly with AVDs&#41; or undesirable decreases in calcium levels &#40;with cinacalcet&#41;&#46; Discontinuation may also be driven by laboratory goal-attainment&#44; suggesting that some clinicians do not view sHPT as a long-term chronic disorder requiring continuous therapy&#46; Most initial paricalcitol prescriptions were administered intravenously&#44; affording a greater clinical influence on treatment decisions for this group&#46; Nevertheless&#44; the pattern of paricalcitol non-persistence &#40;main definition&#41; was no different from the exclusively oral calcitriol-alfa group&#44; suggesting that&#44; for AVDs at least&#44; treatment discontinuation was mainly clinician-led&#46;</p><p id="par0180" class="elsevierStylePara elsevierViewall">Other methodological aspects require consideration&#46; This study utilised data from a single private dialysis provider&#44; hence findings might partially reflect internal policies&#44; limiting generalizability&#46; We assume 100&#37; persistence&#47;non-persistence when this is unlikely&#46; Patients could contribute to each treatment sub-population and&#47;or be on multiple therapies at once and this is not captured&#47;reflected&#44; increasing the potential for confounding&#46; Accordingly&#44; these results could be considered within the framework of &#12287;assessing the effect of the initial intention of a single treatment &#40;or its withdrawal&#41;&#12287;&#46; Our 45-day rule for discontinuation&#44; whilst internally consistent within AROii&#44; is arbitrary and other time periods might have been more appropriate &#40;others have advocated for data-driven definitions based on prescription length<a class="elsevierStyleCrossRef" href="#bib0250"><span class="elsevierStyleSup">25</span></a>&#41;&#46; Our descriptive analytical approach&#44; where statistical modelling was not utilised&#44; does not take into consideration characteristics &#40;observed or otherwise&#41; which could confound the relationship between patients&#12287; biochemistry and treatment initiation&#47;discontinuation and could explain&#44; to an extent&#44; the clinical differences observed between the treatment groups&#46; Similarly&#44; we focused on total treatment populations when sub-group analyses might have been more revealing&#46; For example&#44; the different prescribing pattern in the Iberian Peninsula &#12287; especially with regard to cinacalcet &#12287; might provide insights into biochemical control which could inform healthcare decision-making by clinicians&#44; policy makers&#44; payers&#44; etc&#46;&#44; but this was beyond the scope of the study&#46; Finally&#44; we reported but did not impute missing data which may be important if&#44; for example&#44; less frequent iPTH measurement is indicative of poorer clinical care which in turn is reflected in poorer control of calcium and&#47;or phosphorus&#46;</p><p id="par0185" class="elsevierStylePara elsevierViewall">In conclusion&#44; sHPT biochemistry parameters dictated treatment initiation and discontinuation within the confines of differing geographical treatment patterns&#46; Clinicians appear to adhere to treatment guidelines&#44; although goal achievement is poor&#46; In real-life conditions&#44; better biological control of sHPT appears to be more easily achievable with cinacalcet than with AVDs&#44; where iPTH response might be mediated in part by serum calcium&#46;</p></span><span id="sec0090" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0150">Funding</span><p id="par0190" class="elsevierStylePara elsevierViewall">The ARO CKD Research Initiative is a joint observational research commitment from Amgen and Fresenius Medical Care&#44;
