This phase I/II randomized, placebo-controlled, double-blinded, single-site clinical trial is designed to investigate the effect of a prolonged course of atorvastatin versus placebo on CCM lesional iron deposition assessed by validated quantitative susceptibility mapping (QSM) MRI studies in patients who suffered a symptomatic bleed within the preceding one year.

This phase I/II randomized, placebo-controlled, double-blinded, single-site clinical trial is designed to investigate the effect of a prolonged course of atorvastatin versus placebo on CCM lesional iron deposition assessed by validated quantitative susceptibility mapping (QSM) MRI studies in patients who suffered a symptomatic bleed within the preceding one year. Subjects will also be assessed by lesional and brain vascular permeability MRI using dynamic contrast enhanced quantitative perfusion (DCEQP) and a number of clinical evaluation tools. Subjects shall be followed for 2 years from randomization, the period of highest likelihood of rebleed after a recent CCM hemorrhage. Subjects will undergo clinical and MRI evaluations at baseline, and at 12 and 24 months during the study period. Enrolled subjects and the treating team will be blinded to treatment group allocation.

Atorvastatin Treatment of Cavernous Angiomas With Symptomatic Hemorrhage Exploratory Proof of Concept (AT CASH EPOC) Trial

Phase I-II Randomized, Placebo-Controlled, Single-Blinded, Single-Site Clinical Trial of Atorvastatin in the Treatment of Cavernous Angiomas With Symptomatic Hemorrhage Exploratory Proof of Concept (AT CASH EPOC)

Each patient contributes two outcome measurements (at year 1 and year 2) based on intention-to-treat. Evaluation of the intervention on this outcome will be performed as a time-averaged difference between two arms using a repeated measures analysis implemented as an unadjusted linear mixed model. Patients with outcome measurements in both periods will be included in the initial intention-to-treat analysis. In cases with multiple lesions, only QSM measurements in the lesion with initial hemorrhage (index lesion) shall be considered for the primary outcome assessment.

A secondary analysis of the percent QSM change per year shall be conducted per treatment rendered for all patients with at least one annual epoch of measurements.

Changes in DCEQP vascular permeability measurements in the index lesion and in brain (white matter far from lesion)

Rates of QSM and DCEQP biomarker events, representing increases in index lesional QSM or DCEQP above previously articulated "biomarker thresholds"; rates of clinically overt hemorrhages in the index lesion per adjudicated criteria; and rates of lesional expansion, defined as an increase in maximum lesion diameter on T2 sequences by 2 or more mm

We plan to use a compliance device that would record every time the bottle was opened, thus allowing the study team to track compliance with the protocol and help keep subjects accountable.

Using the modified Rankin scale, we will track subjects' functional outcome changes over the course of the trial.

The purpose of the study is to evaluate the efficacy and safety of subcutaneously administered cladribine versus placebo to stop inflammation and treat disease progression of non-active secondary progressive multiple sclerosis.

Multiple sclerosis is an inflammatory disease of the central nervous system. In most patients, it starts with a relapsing course (RMS) which is caused by acute inflammatory lesions in the brain and spinal cord. RMS transforms at later stages into progressive disease (secondary progressive MS). Currently approved disease-modifying treatments are effective in reducing clinical relapses and brain and spinal lesions visible in MR, but they perform poorly in preventing disease progression and overall disability accumulation. The growing evidence shows that disease progression partially depends on chronic inflammation present in the CNS. Drugs, which may cross the blood-brain barrier and reach inflammatory cells residing in the CNS might be effective in this stage of the disease. Cladribine is one of the DMT approved for RMS. It is a synthetic purine analog with selective lymphocyte toxicity, which enter the CNS and is found in cerebrospinal fluid. In patients treated with cladribine, the oligoclonal bands tend to disappear proving that neuroinflammation is diminished.

The participants of this clinical trial with the later non-active stage of MS are enrolled to be treated with cladribine subcutaneously or a non-active comparator (placebo) for 6 months and followed for the next 2 years, with an MRI scan and clinical evaluation every 6 months. The main questions it aims to answer are if in the non-active stage of MS cladribine is potent to lessen brain volume loss and if it is potent to attenuate inflammation in the CNS.

This is a randomized, placebo-controlled, double-blind, multi-center, phase 2 study of subcutaneous cladribine in non-relapsing, secondary progressive multiple sclerosis. Eligible patients will be randomly allocated in a 1:1 ratio to receive either placebo or subcutaneous cladribine at a dose of 1.8 mg/kg of body weight. The study will consist of three periods: screening, treatment, and follow-up. During the screening, the investigators will assess patient eligibility. During the treatment, cladribine will be given over 6 visit every 5-6 weeks. During the follow-up of 96 weeks, safety and efficacy assessments will be carried out on five visits: the first visit will take place 4 weeks after the last cladribine dose, and the remaining visits will take place every 24 weeks.

There will a rescue option of unblinding and treatment with a full dose of cladribine (cladribine arm) or approved medications (placebo arm) for patients with a severe relapse or ≥ 2 non-severe relapses after enrolment or with a substantial neuroimaging disease activity ≥ 4 Gd+ lesions in any scan, ≥ 3 Gd+ lesions in any two scans, ≥ 2 Gd+ lesions in any three scans, or ≥ 9 new/enlarging T2 lesions on any scan compared with baseline).

All raters will be blinded to treatment allocation. All neuroimaging examinations will be evaluated at a central neuroimaging unit by investigators blinded to treatment allocation.

Study type: interventional (clinical trial) Planned enrolment: 188 patients Allocation: randomized Masking: Double (Participant, Investigator) Primary purpose: Treatment Start Date: October 2022

Study design: The study aims to assess the safety and efficacy of subcutaneous cladribine in patients with SPMS who have not experienced relapses over a year and with or without active lesions on neuroimaging. The study will be randomized, placebo-controlled, and double blind. Because no treatment is approved for inactive SPMS, placebo was chosen as the comparator. Patients receiving other treatments for SPMS or immunosuppressant will not be included.

The study will consist of the following phases:

1. Screening phase (about 4 weeks)
2. Treatment phase, patients will be randomized 1:1 ratio of either cladribine 1,8mg/kg or placebo (30 weeks)
3. Follow-up phase , patients will be followed every 24 weeks for up to 122 weeks for safety and efficacy of the treatment;

Patients: The group of 188 patients fulfilling inclusion criteria and not-fulfilling exclusion criteria will enrolled to the study. All patient has to sign written informed consent form approved by Ethics Committee.

Blinding: Randomization and blinding will be done by "dual assessor" approach . Every site will have two teams of blinded and blinded investigators . The blinded investigators include Principal or treating investigators and rating investigators, as well as blinded treating nurse. The unblinded team includes: Randomizing investigator responsible also for laboratory assessment and unblinded nurse/pharmacist responsible for preparing drugs.

Intervention:

Experimental arm Drug: Cladribine at a dose of 1.8 mg/kg of body weight. Cladribine will be given subcutaneously over 6 visits every 5-6 weeks.

Comparator: Placebo matched to the subcutaneous injection of cladribine.

Follow-up: Patients will be assessed and baseline visit, and every 24 weeks over 24 months since the last dose of the interventional drug. The evaluations include:

1. Medical history, concomitant medication, relapse history
2. Physical examination, neurological examination
3. Clinical assessment: EDSS, T25FWT, 9-HPT,
4. MsQoL and CSSR scale
5. MRI of head and spinal cord (baseline, every 6 months for head and every 12 months for spinal cord)
6. Laboratory and biomarkers evaluation (hematology, coagulation, HIV serology, Hepatitis virus B and C serology, tuberculosis tests (Quantiferron test if necessary), ,

The primary end point will be percentage brain volume change between the last dose (week 24) and end of study (week 122). The primary endpoint was selected based on the widely discussed indications for designing studies in the SPMS. The main secondary clinical end points will assess the change in neurological function on the Expanded Disability Status Scale, Timed 25 Foot Walk, and 9-Hole Peg Test, which measures upper limb function. The change in cognitive function will be assessed with various neuropsychological tests. The main secondary neuroimaging end points will include change in the number of contrast-enhancing lesions, the number of T1-hypointesne lesions ("black holes"), and the volume of T2 lesions. The main exploratory end point will be the change in QSM rim+ lesions on brain neuroimaging; these lesions are markers of chronic, smoldering neuroinflammation that may take place behind an intact blood-brain barrier. Change in the concentrations of neurofilament light chain and glial fibrillary acidic protein, which are markers of brain tissue damage, will be main laboratory end points. An exploratory analysis of inflammatory protein biomarkers will be carried out in serum and cerebrospinal fluid of a selected patients (Luminex). The study will assess the safety of cladribine and its effect on quality of life.

The proposed intervention is well supported by the current evidence. Cladribine is among the few drugs that penetrate an intact blood-brain barrier, which allows action on lymphocytes resident in the central nervous system. The study will assess whether cladribine slows down disease progression clinically and it will use the best currently available indicators of disease progression: brain and cervical cord atrophy and the number of demyelinating lesions. Additionally, it will be assessed whether the presence of QSM rim+ lesions is associated with disease course and the therapeutic effect of cladribine. For example, a reduction in the number of these lesions during cladribine treatment would supports an action of the drug behind the blood-brain barrier. An association between QSM rim+ lesions and the therapeutic effect of cladribine could help select a subgroup of patients most likely to benefit from anti-inflammatory treatments. The measurement of serum biomarkers will enable an assessment of the activation of the peripheral immune system (cytokine, chemokines) and of the therapeutic effect of cladribine (NfL, GFAP). The positive results of the current project will allow the design of a phase 3 trial. A practical benefit of the proposed study is that patients with SPSM, who are currently not eligible for any treatment options, will have a choice to receive a potentially effective therapy, which costs substantially less compared to other therapies in MS.

Background: Multiple sclerosis (MS) is the most common chronic inflammatory, demyelinating disease of the central nervous system, with about 2.5 million patients worldwide, including 45 thousand in Poland. Most patients have relapsing-remitting MS (RRMS) at the start of the disease, in which neurological symptoms appear during relapses and may subside. There is a dozen of disease-modifying treatments for this form of the disease. Several years after the diagnosis of RRMS, the disease progresses into SPMS, in which disability worsens gradually independently of relapses. Patients with SPMS suffer from restricted mobility (need walking aids, wheelchair), cognitive impairment, (difficulties in workplace and in managing everyday life), depression, pain due to spasticity, chronic fatigue, lack of sphincter control, or sexual dysfunction. These patients need more medical help (office visits, rehabilitation, hospitalization), are more often unemployed, and have a lower quality of life than do patients with RRMS. Currently, three disease-modifying treatments are available for patients with SPMS in Europe: interferon beta-1b (low efficacy), mitoxantrone (serious adverse effects), and siponimod. However, these medications can be used only in patients with active disease, i.e., in those with still observed relapses or active brain lesions on magnetic resonance imaging. Therefore, about a half of patients with SPMS cannot receive any disease-modifying treatment. The current understanding of the pathogenesis of MS suggests that there are two types of neuroinflammation since disease onset. Type-1 neuroinflammation is characterized by an acute, focal infiltration of pathogenic lymphocytes and autoantibodies, which is associated with blood-brain barrier disruption. This type of neuroinflammation may be responsible for relapses and contrast-enhancing lesions. Type-2 neuroinflammation is a chronic, smoldering process that takes place behind a closed blood-brain barrier, and it is characterized by slowly expanding lesions and follicle-like lymph structures in the meninges, and diffuse inflammatory changes in white matter and cortex. Other characteristics of type-2 neuroinflammation include microglial and astroglial activation, delayed maturation of oligodendrocytes, and inhibition of remyelination. These processes cause disease progression independently of relapses. Both types of neuroinflammation occur simultaneously since disease onset, but type-2 neuroinflammation is thought to predominate in the secondary progressive phase. Standard neuroimaging methods cannot pinpoint lesions that are specific for type 2 neuroinflammation, but longitudinal brain atrophy and enlargement of lesions can indirectly measure its magnitude. Quantitative susceptibility mapping (QSM), a new imaging technique, can indicate chronic inflammatory lesions that are surrounded by active microglia at the lesion border. Microglia because of iron load form a hypointense rim, and might be thus shown by QSM technique (rim+ lesions). However, QSM is not currently used in clinical practice it is now recommended for use in clinical trials.

The currently available disease modifying-treatments for SPMS act solely or mainly on type-1 neuroinflammation, and because of that they are approved for patients with relapses or active lesions only. Cladribine is approved for the treatment of RRMS. Cladribine substantially decreases the number of contrast-enhancing lesions and relapse frequency in patients with RRMS (an effect on type-1 neuroinflammation). Cladribine may also act on type-2 neuroinflammation i.e. on the autoreactive lymphocytes resident in the central nervous system, including tertiary lymphoid structures, because cladribine penetrates into the central nervous system through an intact blood-brain barrier. The effect on type-2 neuroinflammation is supported by the observation that oligoclonal bands disappear in patients with RRMS and SPMS after cladribine treatment.
