These regulations require the manufacturer to adequately demonstrate the comparability&#8212;mainly analytical&#44; pharmacokinetic and pharmacodynamic&#8212;of each biosimilar with respect to its reference drug&#46; Clinical trials for biosimilars usually focus on the most sensitive indication or indications of the originator and must include a sufficient number of patients to ensure statistical significance&#59; the endpoint is usually non-inferiority&#46; The findings of these studies are then extrapolated to other indications of the reference drug based on the prior demonstration of biosimilarity through comparability studies&#46; The EMA is currently working on a pilot program aimed at advising manufacturers on how to reduce or eliminate the need for clinical trials in biosimilar development&#46;<a class="elsevierStyleCrossRef" href="#bib0180"><span class="elsevierStyleSup">3</span></a></p><p id="par0015" class="elsevierStylePara elsevierViewall">Biosimilars must be approved by the EMA via a single European Union-wide procedure &#40;the so-called centralized procedure&#41;&#46;

Once a favorable opinion has been issued by the CHMP&#44; the European Commission is the body responsible for approving the drug&#44; which is then authorized for sale throughout Europe&#46; In Spain&#44;

Concepts such as the extrapolation of indications &#40;from a reference product to a biosimilar&#41; under the regulatory framework and interchangeability &#40;the non-medical substitution of a biosimilar for a reference drug&#41; have generated uncertainty and very little pertinent data is available&#46;<a class="elsevierStyleCrossRef" href="#bib0185"><span class="elsevierStyleSup">4</span></a> On the other hand&#44; the therapeutic arsenal for psoriasis has benefited from the addition of these cheaper biosimilar drugs which provide an opportunity to improve efficiency parameters within the health system and potentially to achieve significant savings in a complex therapeutic context&#46;

While there is no national law regulating the use of biosimilars&#44; we do have National Treatment Appraisal reports&#44; which generally conclude with a section entitled &#8220;Final considerations of the Treatment Appraisal Coordination Group&#8221; specifying that &#8220;the selection of &#42;&#42;&#42; or another drug with high efficacy in this indication should take into account efficiency criteria&#8221;&#46; However&#44; in the case of tildrakizumab&#44;

discontinuation may be due to a nocebo effect&#44; especially in diseases in which subjective parameters are used to assess therapeutic outcomes &#40;rheumatic diseases&#41; or when the patient has not been adequately informed about the biosimilar they are to receive&#46; However&#44; in other cases discontinuation may be due to differences in the composition of the excipient used or in the characteristics of the administration device&#44; two elements that can lead to lower tolerability&#46; For example&#44; unlike originator adalimumab&#44; all but one of the adalimumab biosimilars currently available in Spain have excipients that contain citrate&#44; acetate&#44; or lactate&#46;</p><p id="par0050" class="elsevierStylePara elsevierViewall">The EGALITY study&#44;

the mean &#40;SD&#41; Psoriasis Area Severity Index &#40;PASI&#41; at the start of treatment with an adalimumab biosimilar was 7&#46;4 &#40;6&#46;2&#41;&#44;<a class="elsevierStyleCrossRef" href="#bib0260"><span class="elsevierStyleSup">19</span></a> a value lower than that reported in the clinical trials&#46; It should&#44; however&#44; be borne in mind that this sample included patients whose disease was adequately controlled with the reference drug prior to the switch and that treatment in real-world practice is started with lower PASI values than those required in clinical trials because physicians are not obliged to impose a clearance interval during which the patient receives no topical or systemic therapy&#46; In that study&#44; 70&#46;8&#37; of the patients had not received prior biologic therapy &#40;biologic na&#239;ve&#41; and 27&#37; had concomitant psoriatic arthritis&#46; It is interesting to note that the mean period during which the disease had been controlled with the originator drug before switching to the biosimilar in the 170 patients with prior treatment was 5&#46;9 years and that the good response initially achieved with the reference drug was better retained in this subgroup than the response achieved in patients who started treatment with biosimilar adalimumab <span class="elsevierStyleItalic">de novo</span>&#44;
