NCT00618527 ↗	Combination Therapy Using Cellcept and Rebif in RRMS	Completed	EMD Serono	Early Phase 1	2006-08-01	The purpose of this trial is to examine the benefits of early combination of CellCept® with Rebif® in long-term management of patients with multiple sclerosis. Quantitation of mRNA for MxA gene from ex-vivo lymphocytes obtained from patients receiving both drugs or interferon alone will be used to gauge the usefulness of this combination therapy. In addition we will examine the safety of combination of mycophenolate mofetil and interferon beta 1a in treatment of multiple sclerosis. This is a pilot study to examine if the combination of CellCept® with Rebif® will prove to be useful in the early treatment of patients with MS. Up-regulation of the MxA gene following the administration of Rebif® will be used as a surrogate marker of interferon bioactivity. This in turn could serve as a surrogate marker of interferon efficacy in these patients. The null hypothesis is that there will not be any difference in the proportion of patients that produce MxA gene transcripts in the Rebif® group as compared to the group that received Rebif® with CellCept® at the end of this study (1 year). The alternate hypothesis is that the combination of CellCept® with Rebif® will prove to be useful in prolonging the efficacy of interferon. In other words, the combination will result in a significant proportion of patients in the treatment group continuing to produce MxA as compared to the proportion of patients producing MxA in the Rebif® arm.

Clinical Trials Update, Market Analysis, and Projection for Methotrexate Preservative-Free

Last updated: November 2, 2025

Introduction

Methotrexate, a cornerstone in the treatment of rheumatoid arthritis, psoriasis, and certain cancers, has historically been formulated with preservatives like benzyl alcohol or phenol to maintain stability and sterility. However, preservative-free formulations have gained traction due to the potential for reduced adverse effects, particularly injection site reactions and systemic toxicity. This report provides an in-depth update on clinical trials, market dynamics, and future projections for preservative-free methotrexate (PFM).

Clinical Trials Update

Recent Developments and Trials

Over the past two years, multiple clinical trials have focused on affirming the safety, efficacy, and tolerability of preservative-free methotrexate formulations, especially for subcutaneous administration. These studies emphasize patient-centric outcomes, including improved tolerability and reduced adverse events.

Key Trials & Outcomes:

• Phase III Trial (NCT04197834): Conducted across multiple centers in Europe and North America, this trial compared preservative-free subcutaneous methotrexate (PF-SC MTX) against conventional formulations in patients with moderate to severe rheumatoid arthritis (RA). Results indicated non-inferiority in disease activity control (measured via DAS28 scores) and demonstrated a statistically significant reduction in injection site reactions (ISRs). The trial, completed in early 2022, confirmed superior tolerability of PF-SC MTX.

• Pediatric Rheumatology Studies: Several early-phase trials are evaluating safety profiles in juvenile idiopathic arthritis (JIA) patients, with preliminary data suggesting that preservative-free formulations mitigate systemic and local toxicity, thereby enhancing compliance.

• Long-term Safety Data: Ongoing extension studies are assessing the durability of efficacy and safety over multiple years, with initial results indicating sustained disease control and fewer adverse events compared to preservative-containing formulations.

Regulatory Approvals and Updates

• Regulatory Approvals: European Medicines Agency (EMA) and the US Food and Drug Administration (FDA) notably approved preservative-free subcutaneous methotrexate in late 2021, recognizing its improved safety profile, especially for patients requiring chronic therapy and those with hypersensitivity to preservatives.

• Labeling and Indications: Post-approval, labeling emphasizes the benefits of preservative-free formulations in reducing injection-related adverse events, which may improve adherence among sensitive patient populations.

Ongoing Clinical Trials

• Phase IV Post-Marketing Studies: Focus on real-world safety and effectiveness, with particular attention to long-term tolerability in diverse populations.
• Combination Therapy Trials: Evaluating PF-MTX as part of multi-drug regimens in various autoimmune and oncologic settings.
