About this trial
This clinical study is a multi-center, randomized, double-blind, placebo-controlled, outpatient study comparing the efficacy of combination of dnaJP1 peptide and hydroxychloroquine versus combination of placebo and hydroxychloroquine in patients with moderately to severely active RA who are naive to cs-, b-, tsp.-DMARDs.
A sample size of 124 patients will be enrolled in the study. Each patient will receive either combination of dnaJP1 peptide and hydroxychloroquine or combination of placebo and hydroxychloroquine in 1:1 allocation ratio.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Diagnosis of rheumatoid arthritis (RA) based on 2010 ACR/EULAR classification criteria
DAS28-ESR score more than 3.2 (at least moderately active)
Male or female with age 21 or above
Ability to understand and sign informed consent
Disqualifiers
On prednisolone >10 mg daily
conventional synthetic (cs-) disease modifying anti-rheumatic drugs (DMARDs) such as sulfasalazine, methotrexate, and leflunomide administered 6 months prior to screening
tissue-specific (tsp.-) DMARDs such as JAK inhibitors
History of lymphoma

Treatments tested in this trial
dnaJP1
DrugThe study drug is dnaJP1 peptide. It is a manmade short protein that can be taken easily as a pill. dnaJP1 works to restore the body's immune tolerance by improving its ability to self-adjust - helps to restore the immune system and improve controls on inflammation that has been lost.
Placebo
DrugThis is the control.
Treatment groups
Trial outcomes
Primary outcomes
To estimate effect size needed to ascertain the power i.e. the number of patients to be tested in the future study to prove superiority of the combination dnaJP1 and HCQ versus placebo and HCQ - To determine this ACR20 will be employed
An American College of Rheumatology (ACR) 20% response (ACR20) response was defined as at least 20% improvement in both the tender joint count and the swollen joint count and at least 20% improvement in 3 of the 5 other core set measures listed below. The core set required the inclusion of 7 clinical end points for all RA trials: swollen joint count, tender joint count, physician's assessment of disease activity, patient's assessment of disease activity, patient's assessment of pain, and patient's assessment of physical function, and levels of an acute-phase reactant (either the C-reactive protein \[CRP\] level or the erythrocyte sedimentation rate \[ESR\]).
A primary endpoint of the study will be to determine safety and tolerability of the experimental treatment in terms of AEs, SAEs, TEAEs
Reporting of Adverse Events
A mechanistic predictor of clinical efficacy at enrolment before first dosing related to immune changes in the cell activation
A combination of high dimensionality technologies will be employed, which will include single cell proteomics, a single cell RNA SEQ flow cytometry and mechanistic studies in vitro
A mechanistic biomarker of treatment response based on 20% change from baseline in increase in Tregs and decrease in inflammatory T cells
Immunological analysis performed on patients samples
Secondary outcomes
To estimate the effect size needed to ascertain the power i.e. the number of patients to be tested in the future study to prove superiority of the combination dnaJP1 and HCQ versus placebo and HCQ - ACR50
The American College of Rheumatology (ACR) 50% response (ACR50) response is the same instruments with improvement levels defined as 50% versus 20% for ACR20
To estimate the effect size needed to ascertain the power i.e. the number of patients to be tested in the future study to prove superiority of the combination dnaJP1 and HCQ versus placebo and HCQ - ACR70
The American College of Rheumatology (ACR) 70% response (ACR70) response is the same instruments with improvement levels defined as 70% versus 20% for ACR20
To estimate the effect size needed to ascertain the power i.e. the number of patients to be tested in the future study to prove superiority of the combination dnaJP1 and HCQ versus placebo and HCQ - DAS28-ESR
Disease Activity Score-28 for Rheumatoid Arthritis with erythrocyte sedimentation rate (DAS28- ESR) describes severity of rheumatoid arthritis using clinical and laboratory data, specifically ESR. The number "28" describes the number of different joints examined in the assessment. The DAS-ESR values range from 2.0 to 10.0 while higher values indicate higher disease activity. A DAS28-ESR score of ≤ 2.6 indicates remission or ≤ 3.2 indicates low disease activity.
To estimate the effect size needed to ascertain the power i.e. the number of patients to be tested in the future study to prove superiority of the combination dnaJP1 and HCQ versus placebo and HCQ - DAS28-hsCRP
Disease Activity Score-28 for Rheumatoid Arthritis with CRP (DAS28-CRP) is a modification of the DAS28-ESR, DAS28-CRP uses the C-Reactive Protein (CRP) value instead of erythrocyte sedimentation rate (ESR). The DAS28-CRP values range from 2.0 to 10.0 while higher values indicate higher disease activity.
