About this trial

The primary objective of the study is to evaluate the efficacy and safety of goflikicept (GFC) and olokizumab (OKZ) in patients with Still's disease

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Voluntarily signed and dated Informed Consent Form (ICF) of the patient agreed to take part in this Study

Trial outcomes

Primary outcomes

1

Proportion of patients who achieved and maintained low disease activity or remission according to DAVID criteria at Day 7 (excluding the arthritis criterion) and achieved DAVID remission criteria at Day 28

Low disease activity according to DAVID criteria is defined as the absence of fever and the presence of only one of the following criteria: * typical skin rash * arthritis * C-reactive protein (CRP) level \> 10 mg/L * Patient's global assessment of arthritis (PtGA) ≥ 5 cm Remission according to DAVID criteria is defined as the absence of fever, typical skin rash, arthritis, CRP level ≤ 10 mg/L and PtGA \< 5 cm

Time frame
Day 7 (low disease activity or remission) and Day 28 (remission)

Secondary outcomes

1

Proportion of patients who developed a flare of Still's disease within 24 weeks after randomization

Flare is defined as the occurrence of criteria consistent with low disease activity starting from Day 28 Low disease activity according to DAVID criteria is defined as the absence of fever and the presence of only one of the following criteria: * typical skin rash * arthritis * C-reactive protein (CRP) level \> 10 mg/L * Patient's global assessment of arthritis (PtGA) ≥ 5 cm

Time frame
at screening, Day 28 (week 4), and every 4 weeks up to Day 168 (week 24)
2

Proportion of patients with resolution of fever on Day 3 and Day 7

Proportion of patients with resolution of fever on Day 3 and Day 7

Time frame
Day 3 and Day 7
3

Proportion of patients who achieved inactive disease while on low-dose glucocorticosteroids (0.1 mg/kg/day) during the study

Inactive disease according to DAVID criteria is defined as the absence of fever, typical skin rash, arthritis, CRP level ≤ 10 mg/L and PtGA \< 5 cm

Time frame
at screening, on Day 7 (week 1), Day 14 (week 2), Day 28 (week 4), and every 4 weeks up to Day 252 (week 36)
4

Proportion of patients who achieved inactive disease without glucocorticosteroids during the study

Inactive disease according to DAVID criteria is defined as the absence of fever, typical skin rash, arthritis, CRP level ≤ 10 mg/L and PtGA \< 5 cm

Time frame
at screening, on Day 7 (week 1), Day 14 (week 2), Day 28 (week 4), and every 4 weeks up to Day 252 (week 36)

Other outcomes

1

Proportion of patients who prematurely discontinued study treatment due to adverse events (AEs)

Proportion of patients who prematurely discontinued study treatment due to adverse events (AEs)

Time frame
Up to Day 252 (Week 36), with follow-up visits at Weeks 4, 8, and 22 (Olokizumab group)
2

Number of patients with clinically significant laboratory abnormalities

Laboratory assessments include complete blood count, blood biochemistry, lipid profile, fibrinogen, ferritin, and urinalysis

Time frame
at screening and up to Day 252 (week 36)
3

Number of patients with clinically significant vital sign abnormalities

Vital signs include blood pressure (mmHg), heart rate (beats per minute), and respiratory rate (breaths per minute)

Time frame
at screening and up to Day 252 (week 36)
4

Change from baseline in heart rate assessed by electrocardiography (ECG)

Electrocardiography (ECG) is performed in 12 leads (I, II, III, aVR, aVL, aVF, V1-V6) to assess heart rate

Time frame
at screening, on Day 28 (week 4), Day 112 (week 16), and every 4 weeks up to Day 252 (week 36)
