DekaJoint: Safety and Preliminary Signs of Efficacy of F8IL10 for Intra-articular Treatment
Study Details
Study Description
Brief Summary
This multicenter, prospective Phase I study is aimed at testing the safety of F8IL10 via i.a. administration once every 4 weeks over 8 weeks in patients with RA who, despite treatment with stable doses (at least 3 months) of DMARDs (conventional, biologic and/or targeted synthetic), present arthritis flare(s) suitable for i.a. injections.

|---|---|
| Experimental: Drug: F8IL10 Overall, 32 patients will participate in case no DLT would occur. In the standard 3+3 dose escalation part, participants will be enrolled in cohorts and will be treated with different doses of F8IL10 (from 0.5 to 10 mg) in order to identify a RD to be further explored in the subsequent dose expansion part. In the dose escalation part, patients will be treated in cohorts of 3 patients with escalating doses of F8IL10 until the MAD is reached and won't exceed 10 mg dose level. In case a DLT would be detected, further 3 patients will be enrolled for that cohort in order to confirm the MAD or to proceed with the next dose level. Therefore, up to 30 patients could be enrolled in the dose escalation part. Following successful identification of the RD, the study will proceed with a dose expansion part and 20 patients will be treated at the RD dose level (patients treated at the RD in the course of the dose escalation phase will contribute to the total sample size). |
Drug: F8IL10
The study consists of a dose escalation of F8IL10 to determine the MTD and the RD when administered intra-articular.
Patients with arthritis flare(s) in "large joints" (shoulders, elbows, knees and ankles, with the exception of hip) and "small joints" (metacarpophalangeal joints, proximal interphalangeal joints, second through fifth metatarsal-phalangeal joints, thumb interphalangeal joints, and wrists) defined as per "2010 Rheumatoid Arthritis Classification Criteria" [1] will be treated with increasing dose of F8IL10 according to the schedule detailed below:
Cohort 1: 0.5 mg F8IL10 Cohort 2: 1 mg F8IL10 Cohort 3: 2.5 mg F8IL10 Cohort 4: 5 mg F8IL10 Cohort 5: 10 mg F8IL10

Outcome Measures
Primary Outcome Measures
- MTD [From the enrollment of each patient until the completion of the treatment (for a maximum of 9 weeks)]
Maximum Tolerated Dose (in dose escalation part). The MAD is defined when at least two patients within a cohort of 2-6 patients experience a DLT (i.e., ≥33% of patients with a DLT at that dose level.
- RD [From the enrollment of each patient until the completion of the treatment (for a maximum of 9 weeks)]
Recommended Dose (in dose escalation part). The RD is defined by the Data Safety Monitoring Board (DSMB) among the safely tested dose level (i.e. not exceeding the MTD) considering the overall results dataset (e.g. safety, tolerability, efficacy, immunogenicity, pharmacokinetics) obtained in this study.
Secondary Outcome Measures
- Safety and Tolerability [From the start of treatment period (for a maximum of 9 weeks) to the end of follow-up period (for a maximum of 6 months)]
Number and frequency of Adverse Events (AEs), Serious Adverse Events (SAEs), Dose Limiting Toxicities (DLTs) and Drug-Induced Liver Injuries (DILIs)
- Efficacy measured as improvement in visual analogue scale for involved joint pain (jVAS) [From the start of treatment period (for a maximum of 9 weeks) to the end of follow-up period (for a maximum of 6 months)]
Preliminary efficay findings using jVAS scale in rheumatoid arthritis for quantifying pain intensity. Patients will assess their own current level of pain related to arthritis in target joint(s) that has been/will be injected. The information refers to a score of the joint pain perceived by the patient over the 7 days prior to the assessment and will be recorded using a 100-mm horizontal VAS where the left end represents "no pain (0%)" and the right end represents "severe pain (100%)". The assessment provided at Day 1 (Week 1) will be considered as baseline measurement.
- Quality of life - Collection of HAQ-DI for the evaluation of physical function [At day 1 and 29 (F8IL10 administration) to the end of follow-up period (for a maximum of 6 months)]
Health Assessment Questionnaire-Disability Index (HAQ-DI) as validated tool for the evaluation of Disability Index (DI) or Functional Disability Index (FDI) by considering 8 sections: dressing, arising, eating, walking, hygiene, reach, grip, and activities. There are 2 or 3 questions for each section. Scoring within each section is from 0 (without any difficulty) to 3 (unable to do). For each section, the score given to that section is the worst score within the section. The 8 scores of the 8 sections are summed and divided by 8. Changes from baseline through treatment period and follow-up will be quantified.
- Quality of life - Collection of SF-36 for the evaluation of overall health status [At day 1 and 29 (F8IL10 administration) to the end of follow-up period (for a maximum of 6 months)]
Short Form Health Survey 36 (SF-36) as validated tool for subject-reported indication of overall health status, including multi-item scales measuring 8 health concepts: (1) physical functioning; (2) role limitations because of physical health problems; (3) bodily pain; (4) social functioning; (5) general mental health; (6) role limitations because of emotional problems; (7) vitality; and (8) general health perceptions. These are summarized in two summary measures of physical and mental health: the Physical Component Summary and Mental Component Summary. Lower scores equate to higher disability and higher scores equate to lower disability. Changes from baseline through treatment period and follow-up will be quantified.
- Quality of life - Collection of FACIT-F for the evaluation of self-reported fatigue and its impact upon daily activities and function [At day 1 and 29 (F8IL10 administration) to the end of follow-up period (for a maximum of 6 months)]
Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F) as validated 13-item questionnaire for the assessment of self-reported fatigue and its impact upon daily activities and function. It uses a 5-point Likert-type scale (0 = not at all; 1 = a little bit; 2 = somewhat; 3 = quite a bit; 4 = very much). As each of the 13 items of the FACIT-Fatigue scale ranges from 0-4, the range of possible scores is 0-52, with 0 being the worst possible score and 52 the best. Changes from baseline through treatment period and follow-up will be quantified.
- Assessment of joint inflammation with ultrasound [At day 1 and 57 of treatment period]
Assessment of improvement of joint synovitis using ultrasound (US) pre-treatment and after the treatment period
- Assessment of damage with ultrasound [At day 1 and 57 of treatment period]
Assessment of non-progressive bone erosion using ultrasound (US) pre-treatment and after the treatment period
- Pharmacokinetic (PK) profile F8IL10- Area Under the Curve (AUC) [At day 1 and 29 (F8IL10 administration)]
Blood/Synovial fluid samples for PK profile of F8IL10 profile measurements will be collected from all patients enrolled in the study and who receives at least one dose of study drug and have adequate PK sampling. Standard PK parameter AUC will be estimated.
- Pharmacokinetic (PK) profile F8IL10- Maximum drug concentration (Cmax) [At day 1 and 29 (F8IL10 administration)]
Blood/Synovial fluid samples for PK profile of F8IL10 profile measurements will be collected from all patients enrolled in the study and who receives at least one dose of study drug and have adequate PK sampling. Standard PK parameter Cmax will be estimated.
- Pharmacokinetic (PK) profile F8IL10 - Terminal half-life (T½) [At day 1 and 29 (F8IL10 administration)]
Blood/Synovial fluid samples for PK profile of F8IL10 profile measurements will be collected from all patients enrolled in the study and who receives at least one dose of study drug and have adequate PK sampling. Standard PK parameter T½ will be estimated.
- Immunogenicity of F8IL10 (Human Anti-Fusion Antibody formation [HAFA]) [At day 1 and 29 (F8IL10 administration) to the first visit of follow up (week 13)]
Blood samples to assess the potential development of antibody formation to F8IL10 will be collected during the treatment period and in the first Follow-up
