Safety, tolerability and efficacy of Descarte-08 in children, adolescents and young adults with childhood-onset systemic lupus erythematosus, ANCA-associated vasculitis, juvenile myasthenia gravis, and juvenile dermatomyositis

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

At least age 12

definitive diagnosis of childhood-onset systemic lupus erythematous, juvenile Myasthenie gravis, juvenile dermatomyositis and AAV

Signs and symptoms of moderate disease

History of systemic treatment

Disqualifiers

Major chronic illness that is not well managed at the time of study entry and in the opinion of the investigator may increase the risk to the patient;

Abnormal PT/INR or PTT increased > 1.5-fold or patient is on anticoagulation therapy (except in cases of elevated PTT with documented lupus anticoagulant; or in patients who have been on stable doses of anticoagulation therapy for more than 6 months of VTE diagnosis; or in patients on stable doses of anticoagulation therapy for at least 8 weeks of atrial fibrillation diagnosis; these conditions will not be exclusionary unless, in the investigator's opinion, they make participation in the study unsafe);

ANC < 1000 cells/microliter ;

Hemoglobin < 8.0 g/dL ;

Treatments tested in this trial

  • Descartes-08

    Drug

    In part 1, three different doses will be administered to 3 participants with either disease indication to establish maximum tolerated dose In part 2, the MTD established in Part-1 will be administered as six once-weekly infusions to up to 10 participants per each of four baskets (cSLE, AAV, JDM and JMG) in an outpatient setting.

Treatment groups

50 Participants
are divided into 2 treatment groups
Group A: Part 1: Decartes-08 to establish Maximum tolerated doseExperimental treatment 1 intervention
Group B: Part 2: Decartes-08 infusions once weekly for 6 weeksExperimental treatment 1 intervention

Trial outcomes

Primary outcomes

1

Maximum tolerated dose in Part 1, type and frequency of treatment related SAE's in Part 2

The primary endpoint for Part-1 is the Maximum Tolerated Dose (MTD), defined as the Dose Level at which no more than 20% of the patients treated have shown Dose-Limiting Toxicity (DLT), i.e. at which 3 patients received all 6 weekly infusions without a DLT by Day 50; or 6 patients received 3 weekly infusions with no more than 1 patient having a DLT by Day 50. The primary endpoint for Part-2 is the type and frequency of treatment-related SAEs. This will be assessed on Days 22, 50 and Months 3,6,9,12
