January 15, 2020 updated by: Biotest

A Prospective, Double-blind, Randomized, Placebo-controlled, Repeated Dose, Multicentre Phase IIa Proof-of-Concept Study With BT063 in Subjects With Systemic Lupus Erythematosus

The purpose of this study is to evaluate the safety and efficacy of repeated intravenous infusions of the study drug BT063 in patients with Systemic Lupus Erythematosus (SLE) compared with people who receive a placebo.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Study 990 is a Phase IIa, proof-of-concept study of BT063 in subjects with SLE. This study is divided into 2 parts. After Part I an interim analysis will be performed. Each Part will enrol 18 subjects. Subjects will be randomly assigned to receive BT063 or Placebo 8 times over 12 weeks and will be followed for 4 months after their last dose.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years to 71 years (Adult, Older Adult)

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Adverse Events
Time Frame: Baseline through End of Trial Visit (Week 14)
Number of Participants with Adverse Events (Including SAEs and AEs leading to discontinuation) from Baseline through End of Trial Visit (Week 14)
Baseline through End of Trial Visit (Week 14)
Number of Participants With Changes of Safety Parameters
Time Frame: Baseline through End of Trial Visit (Week 14)
Number of Participants with changes in vital signs, ECGs, Safety laboratory parameters (full blood count including white differential count, clinical chemistry, thyroid hormones, urinalysis, and faecal occult blood test), Development of anti-drug antibodies against BT063 (anti-BT063), Immunological status of potential viral and bacterial infections (HBV, HCV, HIV, tetanus, diphtheria tuberculosis), EBV / CMV Serology, Premature withdrawals.
Baseline through End of Trial Visit (Week 14)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Improvements of Joints
Time Frame: At week14 and week 28
Number of Participants with 50% improvement of swollen/tender joints. A total of 66/68 joints was assessed for the swollen/tender joint count. A joint that is normal (no tenderness or swelling), without signs of inflammation will be graded as 0. A joint with tenderness will be graded as 1 for tender joint count and a joint with swelling will be graded as 1 for swollen joint count. Joints suspected or known to have ischemic osteonecrosis are not to be taken into consideration. Higher scores indicate more disease activity.
At week14 and week 28
Number of Participants With Improvement of Skin
Time Frame: At week14 and week 28

Number of Participants with 50% improvement in Cutaneous Lupus Erythematosus Disease Area and Sensitivity Index (CLASI) Activity score. The CLASI is an assessment over 13 body regions (scalp, ears, nose - including malar area, rest of the face, V-area neck - frontal, post. neck & shoulders, chest, abdomen, back and buttocks, arms, hands, legs, feet) and consists of 2 scores: total activity score and total damage score. Only the activity score was used in this study.

The minimum score possible on this scale is 0 and the maximum score is 70. The higher scores mean a worse outcome.
At week14 and week 28
Percent Changes in Systemic Lupus Erythematosus Disease Activity Index 2000
Time Frame: Baseline to week 14 and at week 28

Percent changes in Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) scores from baseline SLEDAI-2K score.

The SLEDAI-2K is a global index that measures SLE disease activity. It includes 24 items for the 9 organs/systems. Scores range from 0 to 105; a score of 6 is considered clinically important. The index measures disease activity within the last 10 days. Higher scores mean worse outcome. Negative percent change means reduced disease activity.
Baseline to week 14 and at week 28
