Summary

The purpose of the following phase II clinical trial is to determine safety and effectiveness of Janus kinases and Rho-kinases inhibitor (JAK/ROCKi) in patients with Rheumatoid arthritis after oral administration of investigational medicinal product (IMP) called CPL409116. JAK inhibitors are a new class of small molecule drugs that modulate inflammatory pathways by blocking one or more JAK receptors. In recent years, JAK inhibitors have emerged as a new option for the treatment of various inflammatory diseases, including rheumatoid arthritis, psoriatic arthritis, skin disorders and others. CPL409116 inhibits JAK1 and JAK3 with less inhibitory activity against JAK2 and Tyk2. Inhibition of these kinases decreases inflammatory cytokine release which in turn decreases lymphocyte activation and proliferation. Moreover, CPL409116 blocks Rho-kinases (ROCKs), which are involved in diverse cellular processes including actin cytoskeleton organization, cell adhesion and motility, proliferation, apoptosis as well as smooth muscle contraction. ROCKs signalling is one of the major pathways implicated in the pathogenesis of cardiovascular, renal as well as fibrotic diseases. However recent data indicate their role in immune cell regulation and inflammatory disease development. CPL409116 was designed predominantly for the therapy of immune-related diseases: rheumatoid arthritis (RA) or psoriasis but the unique mode of action of this compound may be beneficial for patients suffering from fibrotic complications developing on the basis of autoimmune diseases. RA is a chronic systemic autoimmune disease characterised by persistent joint inflammation leading to loss of joint function as well as cartilage and bone damage. Chronic, progressive course of the disease results in disability, reduced quality of life, as well as higher comorbidity and mortality rates. It is well documented that JAK kinases play a pivotal role in cytokine receptor signalling to phosphorylate and activate signal transducer and activator of transcription (STAT) proteins. Several of these JAK-controlled cytokine receptor pathways are immediately involved in the initiation and progression of RA pathogenesis. After preclinical studies conducted by Celon Pharma, CPL409116 could have been classified as a good clinical candidate for the treatment of patients with RA and next, results obtained after the phase I clinical trial in healthy volunteers confirmed its safety and a good pharmacokinetic profile.

Description

This is to be a 12-week, phase II, multicentre, randomised, double blind, efficacy and safety study of CPL409116 in participants with active rheumatoid arthritis who are taking methotrexate but have an inadequate response to this drug. Eligible subjects are to be randomised into one of the 4 treatment arms (60 mg BID, 120 mg BID, 240 mg BID of CPL409116 or palcebo) and approximately 100 male and female subjects are to be enrolled in the study (25 patients per arm). The study is to include the screening period, the treatment period and the follow-up period. In all treatment arms the investigated product/ placebo is to be administered orally for 12 weeks in a blinded fashion. In order to maintain the blind and minimize bias, all subjects will receive the same number and types of tablets each day of treatment. In the screening period, patients are to undergo screening assessments from Day -28 to Day 0. Rolling admission is to be employed in this study. Patients that fulfil all the inclusion criteria and none of the exclusion criteria will be considered eligible for this study. During the treatment period, patients are to be dosed with 60, 120, 240 mg CPL409116 administered twice a day or placebo administered twice a day for 85 consecutive days (Day 1 to Day 85). The MTX dosage which should be orally or parenterally administered by participants during the study and before the start of the study should be in the range of 15-25 mg/ week, which is typical of current clinical practice. MTX must be applied for at least 12 weeks prior to Screening, and with no change in dosage and route of administration for at least 8 weeks prior to Day 1/ baseline. Within the follow-up period patients are to undergo safety assessment for 4 weeks after the last dose of IMP.

Current acute or chronic HCV and/or HBV infection
Subjects who are seropositive for antibodies to hepatitis C virus (at Screening)
may be allowed to participate in the study provided they have 2 negative HCV RNA
test results 6 months apart after completing antiviral treatment and prior to
Screening, and have a third negative HCV RNA test result at Screening
HBV serology
a positive result for HBsAg will be exclusionary
a positive result for anti-HBc antibodies in subjects negative for HBsAg
requires HBV DNA testing. A positive test result for HBV DNA will be
exclusionary
For subjects who are negative for HBsAg and anti-HBc antibodies and has had
a HBV vaccination a positive test result for anti-HBs antibodies is expected
such subjects may be enrolled without HBV DNA testing. In non-vaccinated
patients positive for anti-HBs antibodies HBV DNA testing is required
a positive result for HBV DNA will be exclusionary
NOTE: enrolled subjects positive for anti-HBc antibodies and/or anti-HBs antibodies
(except for vaccinated subjects negative for anti-HBc antibodies and positive for
anti-HBs antibodies) will have repeated HBV DNA testing at week 6 (or early
termination visit) and last follow-up visit. A positive result for HBV DNA testing in
these subjects will require immediate interruption of study drug and a hepatologist
consultation

Association [NYHA] class III or IV), or within the last 6 months, a cerebrovascular
accident, myocardial infarction, unstable angina, unstable arrhythmia or any other
cardiovascular condition which, in the opinion of the investigator, would put the
subject at risk by participation in the study
History or presence of other significant concomitant illness that, according to the
Investigator's judgment, would place the participant at unacceptable risk when taking
investigational product or could interfere with the interpretation of data
History of other (than RA) chronic inflammatory arthritis or systemic autoimmune
disorder other than Sjögren's syndrome secondary to RA, that may confound the
evaluation of the effect of the study intervention such as mixed connective tissue
disease, psoriatic arthritis, juvenile chronic arthritis, spondyloarthritis, Felty's
Syndrome, systemic lupus erythematosus, scleroderma, Crohn's disease, ulcerative
colitis, or vasculitis
Presence of fibromyalgia that, in the Investigator's opinion, would make it difficult
to appropriately assess RA activity for the purposes of this study

the Investigator, are clinically significant and indicate an unacceptable risk for the
subject's participation in the study (eg, QTc >450 msec or a QRS interval >120 msec)
If QTc exceeds 450 msec, or QRS exceeds 120 msec, the ECG should be repeated two more
times and the average of the three QTc or QRS values should be used to determine the
subject's eligibility
Pregnancy or breast- feeding
NOTE: Women of childbearing potential must have a negative pregnancy test at
Screening, at randomization and at scheduled visits throughout the study
Narcotic and alcohol addiction or abuse (more than 14 alcohol units per week: one unit
= 150 mL wine, 360 mL beer, 45 mL 40 % spirits) (UK guidelines)
Positive drug screen or alcohol breath tests
Blood donation within the last month before Day1/ baseline
Current therapy with any disease-modifying antirheumatic drugs (DMARDs) other than
MTX. All DMARDs (except for MTX) must be ceased before Day 1/ baseline, as follows
month before: etanercept, sulfasalazine, chloroquine/ hydroksychloroquine
months before: leflunomide (4 weeks in case of cholestyramine washout)
months before: adalimumab, golimumab, infliksimab, certolizumab, tocilizumab
gold, cyclosporine, penicillamine, azathioprine

use of one (and only one) biologic agent (tocilizumab or TNF-alpha inhibitor) is
allowed if administered for less than 3 months or ceased because of other than lack of
effectiveness causes
Vaccinated with a live vaccine (i.e. containing live or attenuated pathogens) within 3
months before Day 1/ baseline or necessity to vaccinate during the clinical trial
NOTE: Investigators should ensure that all study enrolment criteria have been met at
Screening and on Day 1. If a patient status after Screening changes at baseline (Day 1)
such that the study patient no longer meets all eligibility criteria, then the patient
should be excluded from participation in the study (such patient is to be considered as
screen failure). History or presence of any other medical or psychiatric condition, or
laboratory abnormality that, in the opinion of the Investigator, may place the subject at
unacceptable risk for study participation or may interfere with the study results should be
considered as an exclusion criterion
