Relapsing-Remitting Multiple Sclerosis clinical trials at UCSF

This is a phase II, multicenter, randomized, parallel-group, partially blinded, placebo and Avonex (interferon beta-1a) controlled dose finding study to evaluate the efficacy as measured by brain MRI lesions, and safety of 2 dose regimens of ocrelizumab in participants with Relapsing Remitting Multiple Sclerosis (RRMS).

The clinical trial is intended to assess for clinical evidence of Clemastine Fumarate as a myelin repair therapy in patients with chronic inflammatory injury-causing demyelination as measured by multi-parametric MRI assessments. No reparative therapies exist for the treatment of multiple sclerosis. Clemastine fumarate was identified along with a series of other antimuscarinic medications as a potential remyelinating agent using the micropillar screen (BIMA) developed at the University of California, San Francisco (UCSF). Following in vivo validation, an FDA IND exemption was granted to investigate clemastine for the treatment of multiple sclerosis in the context of chronic optic neuropathy. That pilot study was recently completed and is the first randomized control trial documenting efficacy for a putative remyelinating agent for the treatment of MS. The preselected primary efficacy endpoint (visual evoked potential) was met and a strong trend to benefit was seen for the principal secondary endpoint assessing function (low contrast visual acuity). That trial number was 13-11577. This study seeks to follow up on that study and examine clemastine fumarate's protective and reparative effects in the context of chronic demyelinating brain lesions as imaged by multi-parametric MRI assessments. The investigators will be assessing the effects of clemastine fumarate as a remyelinating therapy and assessing its effect on MRI metrics of chronic lesions found in patients with a confirmed diagnosis of relapsing-remitting multiple sclerosis. In addition to using conventional multi-parametric MRI assessments, this study will also evaluate a new MRI technique called Ultrashort Echo Time (UTE) MRI to assess the effects of clemastine fumarate as a remyelinating therapy of chronic lesions found in patients with a confirmed diagnosis of relapsing-remitting multiple sclerosis and compare it to the other assessments.

In this Phase 1b open-label prospective clinical trial, patients with relapsing-remitting MS will undergo FMT of FMP30 (donor stool) via colonoscopy and immunological efficacy endpoints will be assessed at various time points. The active phase of the study will continue for 12 weeks post-FMT with safety and biomarker (engraftment) follow-up for 48 weeks. A parallel observational control arm of MS patients who otherwise satisfy study inclusion criteria based on their MS phenotype, demographics, disease duration and prior use of allowable MS therapies, will be recruited as a comparison observational group to measure stability of stool and serum immunological measures. The study duration for the Observational Control Arm is 12 weeks.
