Clinical Trial Summary

This will be a 1:1 randomized open label trial. European and outside Europe centres will be involved. Aim of the project is to conduct a head-to-head comparison of effectiveness of two approved disease modifying treatments (DMTs) in patients with relapsing remitting multiple sclerosis (RRMS). The term effectiveness refers to efficacy in a real life setting: this is intended to be in fact the first pragmatic multi-centre randomised controlled trial to directly assess the effectiveness of the new oral agents approved for MS (fingolimod/FTY versus dimethyl-fumarate/DMF) on disease activity, disability progression, quality of life, functioning and symptoms. It will be a randomized trial taking place in clinical care setting and comparing existing therapies, any of which may constitute standard care for naive patients or sub optimal responders to first-line drugs. Post hoc analysis will also identify the better treatment strategy on the different patient subgroups. Patient overall disease experience will be considered for the first time as the most important outcome. In fact, in addition to classical "no evidence of disease activity" (NEDA), a new composite NEDA taking account also of patient point of view and quality of life, will be proposed. Finally,the specific effectiveness profile of the two DMTs will be addressed, by exploring comparative benefits on different outcomes (disease activity, disability progression, brain atrophy, quality of life, fatigue, psychiatric and cognitive symptoms, medication satisfaction).

Description:

Background and significance

1. The expansion of the treatment landscape in MS has increased the complexity of treatment decisions. Recommendations and algorithms can help to maximize the benefit of each available therapy; however, there is currently no consensus algorithm available, with most of the recently published recommendations being regional and most guidelines currently used in clinical practice, being driven by the labels of the therapies. The lack of head-to-head clinical trials for approved drugs is crucial since head-to-head trials constitute the gold standard for efficacy comparisons. This kind of information is mandatory for informed and objective health decisions. The present proposal aims at filling this critical gap in evidence. Randomized head-to-head trials are the best method for evaluating the efficacy of different treatments and to help the clinicians and the patients in health decision making. Randomized controlled trials, designed as experiments with high internal validity, have the ability to determine cause effect relationships. These experiments employ comprehensive designs to control for most, if not all, sources of bias by means of randomization, blinding, allocation concealment, etc. Usually, extended inclusion and exclusion criteria are used to identify a clearly defined population group of participants who would benefit from the intervention under investigation. Although the above experimental design, if correctly applied, leads to well-controlled trials with statistically credible results, the applicability of these results to real life practice may be questionable.

Here the investigators aim at conducting a comparative open label trial preserving the internal validity due to randomization and generalizability due to a pragmatic design. The term pragmatic is used for trials designed to test the effectiveness of the intervention in a broad routine clinical practice. The explanatory trial is designed in order to control for all known biases and confounders, so that the intervention's effect is maximized. The pragmatic trial, on the other hand, is designed to test interventions in the full spectrum of everyday clinical settings in order to maximize applicability and generalizability.1 This is intended to be the first pragmatic multi-centre randomised controlled trial to directly assess the effectiveness of the new oral agents approved for MS (FTY/gilenya versus DMF/tecfidera). FTY (0.5 mg/day) and DMF (240 mg twice daily) are both efficacious in the treatment of MS and both offer the convenience of an oral administration. As such they are similarly valuable alternative treatments for MS patients, and are indeed frequently proposed as possible alternative treatment options to MS patients. Indication for FTY is restricted in Europe to second line in first-line therapy non responders or in active naïve patients. DMF is highly prescribed also in active naive patients and as switching strategy in patients who do not adequately respond to self-injectable DMTs, such as FTY.

The need for randomized trials with approved drugs exists when treatment decision in clinical practice is challenged by the lack of evidence of superiority of one drug for a specific group of patients.

The efficacy profile of the two oral drug have been characterized in large clinical development programs. Oral therapies have been shown to offer benefits with regard to these clinical and MRI outcomes when compared with placebo in phase 3 trials.2-5 The clinical efficacy of these therapies over traditional injectable DMTs has been demonstrated for FTY in the trial assessing injectable interferon versus FTY720 oral in RRMS (TRANSFORMS).6 Findings of these phase 3 trials indicate that oral therapies may represent an advance in the treatment of MS because they offer effective treatment options that are often better tolerated and more convenient than the traditional injectable DMTs. There are no head-to-head controlled trials comparing the efficacy of the different oral DMTs. This is an area of much interest to neurologists and healthcare decision makers; therefore, indirect treatment comparisons have recently been performed. Of these, a recent study has compared FTY with DMF using a network meta-analysis approach and found no significant differences in relapse rate or in the proportion of patients with disability progression.7 Standard network meta-analysis methods may be susceptible to bias because of differences in trial populations and methodologies. Subgroup and post hoc analyses of the phase 3 trials of DMTs have demonstrated that differences in patient baseline characteristics influence the observed effect of DMTs on relapse rate and disability progression,6,8 and that the application of different definitions of disability progression has a large impact on disability outcomes.9 Therefore, it is important to adjust for these potentially confounding factors when assessing the comparative efficacy of these oral DMTs. It has been reported that FTY therapy results in a higher probability of no evidence of disease activity (NEDA) than DMF therapy when phase 3 trial data are indirectly compared and differences between trials are adjusted for.10 These findings must, however, be interpreted with caution, owing to the assumptions inherent in any modeling approach.

The need for high-quality, widely applicable evidence is gaining momentum, especially amidst health care policy makers. The increased costs of interventions and health care in a resource-limited environment have fueled the demand for clinically effective and applicable evidence. Here the investigators aim at conducting a comparative open label trial preserving the internal validity due to randomization and generalizability due to a pragmatic design. It will be the first randomized pragmatic trials in MS. Policy makers have an active interest in pragmatic trials, since these are designed to answer the question most relevant to a decision maker's agenda: comparative effectiveness of interventions in the routine practice. The availability of comparative data from routine practice will help policy makers to efficiently allocate resources and manpower and will drive patients and clinicians in shared and informed health decisions. The evolving MS landscape, in which a number of new treatments are appearing—each with their own benefits and risks—will require a change in the nature of interactions between patients and their physicians, with a shared approach to clinical decision making that emphasizes patient-related goals. Together, these innovations in MS management offer exciting new opportunities to optimize treatment outcomes. This will necessitate attention both to traditional clinical endpoints such as relapses and disability, to objective radiological surrogates of disease activity, and to newer outcome measures such as brain atrophy , cognition and patient-reported outcomes. In line with this, the present proposal aims at comparing the effectiveness of two oral MS agents on patient overall disease experience. If, traditionally, both clinical trials and routine medical care have relied on outcomes assessed by healthcare professionals, here the investigators want to focus also on the importance of self-evaluation of health, thus growing participation of individuals in their own care. The investigators can foresee a continuum where patient empowerment contributes to improve his/her healthcare and, at the same time, makes valuable medical data accessible to the medical community for future therapeutic developments.

The whole idea of applicable and generalizable research is very appealing and of benefit to the health sciences community.

This 54-item instrument generates 12 subscales along with 2 summary scores, and 2 additional single-item measures. The MSQOL-54 is a structured, self-report questionnaire that the patient can generally complete with little or no assistance. MSQOL-54 scale scores are expressed on a 0-100 scale: higher scores indicating better functioning. There is no single overall score. Two summary scores, physical health and mental health, can be derived from a weighted combination of scale scores. In addition there are 12 subscales: physical function, role limitations-physical, role limitations-emotional, pain, emotional well-being, energy, health perceptions, social function, cognitive function, health distress, overall quality of life, sexual function and satisfaction with sexual function and change in health.	over 12 and 24 months
