DESCRIPTION (provided by applicant): Moderate-to-severe psoriasis affects 1.5 million people in the U.S. Multiple, well-designed, population-based observational studies provide convincing evidence that psoriasis is associated with 1.5- to 2-fold increased risk for cardiovascular and metabolic complications. However, the effect of immunomodulatory therapy on risk has not been adequately evaluated. Nor has risk been evaluated with respect to intermediating physiologic measures. We propose to assess the comparative effectiveness of immunomodulatory drugs used by patients with moderate-to-severe psoriasis for improving body mass index, blood pressure, lipids, and fasting plasma glucose. If these physiologic measures are worsened in psoriasis but are substantially resistant to immunomodulatory therapy, then those at high risk should be identified for screening and early behavioral intervention. On the other hand, if immunomodulatory therapy for psoriasis improves or worsens these measures, then evidence is urgently needed by doctors and patients to make sound treatment decisions that balance benefits against risks and costs given the patient's personal risk profile. The drugs under study will include anti-TNF agents, methotrexate, oral retinoids and cyclosporine. Risk on these drugs will be compared to risk on phototherapy without systemic agent. The number of patients eligible for the study is 8385, with ample numbers having exposure to the study drugs (anti-TNF, methotrexate, oral retinoids, and cyclosporine) and comparison therapy. Because the focus is on physiologic measures, the study has substantial power for subgroup analysis, with the goal of selecting patients for personalized therapy. The study will provide information that can be translated immediately and directly to the clinical setting so that doctors and patients can make the best treatment choices given the patient's underlying risk for cardiovascular disease and diabetes. We have estimated the potential impact of the study using conservative assumptions. If optimizing drug therapy reduces risk by even 5%, then 40,000 cases of cardiovascular disease and diabetes could be prevented. Alternatively, the study could demonstrate no benefit of anti-TNF therapy on physiologic risk factors for cardiovascular disease and diabetes, in which case the value of anti-TNF therapy could be optimized by maintaining valid, tight prescribing indications. The study could also inform study design and future assessments of the indirect benefits of specialty pharmaceuticals.

描述（由申请人提供）：在美国，中重度牛皮癣影响150万人。多个精心设计的、基于人群的观察性研究提供了令人信服的证据，表明牛皮癣与心血管和代谢并发症的风险增加1.5至2倍相关。然而，免疫调节疗法对风险的影响尚未得到充分评估。也没有评估关于中间生理措施的风险。我们建议评估中重度牛皮癣患者使用的免疫调节药物在改善体重指数、血压、血脂和空腹血糖方面的相对有效性。如果这些生理指标在银屑病中恶化，但对免疫调节治疗有很大的抵抗力，那么应该确定高危人群进行筛查和早期行为干预。另一方面，如果银屑病的免疫调节治疗改善或恶化了这些措施，那么医生和患者迫切需要证据来做出合理的治疗决策，在考虑患者个人风险状况的情况下，平衡收益与风险和成本。正在研究的药物将包括抗肿瘤坏死因子、甲氨蝶呤、口服类维生素a和环孢素。使用这些药物的风险将与不使用全身药物的光疗风险进行比较。符合研究条件的患者人数为8385人，其中大量患者暴露于研究药物（抗肿瘤坏死因子、甲氨蝶呤、口服类维生素a和环孢素）和比较治疗。由于研究的重点是生理指标，因此该研究具有很强的亚组分析能力，其目标是选择患者进行个性化治疗。这项研究将提供可以立即直接转化为临床环境的信息，这样医生和患者就可以根据患者患心血管疾病和糖尿病的潜在风险做出最佳治疗选择。我们使用保守假设估计了这项研究的潜在影响。如果优化药物治疗将风险降低5%，那么就可以预防40,000例心血管疾病和糖尿病病例。或者，该研究可能表明抗tnf治疗对心血管疾病和糖尿病的生理性危险因素没有益处，在这种情况下，可以通过保持有效、严格的处方指征来优化抗tnf治疗的价值。该研究还可以为研究设计和未来对特殊药物间接益处的评估提供信息。
