General information about the trial
|
|||
Main objective of the trial |
Primary Objective:
The primary objective of the main study (at week 36) is to evaluate the neutralization of the IFN gene signature following treatment with IFN-K, as measured by the change from baseline of the expression of IFN-induced genes and to evaluate the efficacy of treatment with IFN-K using the British Isles Lupus Assessment Group (BILAG)-based Composite Lupus Assessment (BICLA) response modified by mandatory CS tapering.
|
||
Protection of trial subjects |
The Phase IIb - IFN-K-002 study was conducted in accordance with the European Union Clinical Trial Directive, and local national laws as applicable, International Conference on Harmonization (ICH) E6 GCP guidelines, and the guidelines of the Declaration of Helsinki, revised form of 64th World Medical Association (WMA) General Assembly, Fortaleza, Brazil , 2013.
An independent data safety monitoring board (iDSMB) consisting of experts in the appropriate disciplines, has been set up to oversee the conduct of the study as well as the safety with specific attention on "Lupus flares" and "Infections". Data review meetings held by iDSMB were planned 6 months after randomization of the first subject and then on a 6-monthly basis unless unscheduled meetings are required to adress particular safety concerns.

Subsequently defined using consensus methodology, LLDAS is attained if all the following items are met:
- SLEDAI-2K ≤4, with no activity in major organ systems (renal, CNS, cardiopulmonary, vasculitis, fever) and no hemolytic anemia or gastrointestinal activity
- No new features of lupus disease activity compared with the previous assessment
- SELENA-SLEDAI physician global assessment (PGA, scale 0–3) ≤1
- Current prednisolone (or equivalent) dose ≤7.5 mg daily
- Well tolerated standard maintenance doses of immunosuppressive drugs and approved biological agents, excluding investigational drugs

Timeframe for reporting adverse events |
Adverse Events (AEs) non serious and serious (SAEs) were collected from the start of study medication to Week 36.
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Adverse event reporting additional description |
Due to IFN-K mechanism of action, i.e. immunization, and the administration route, i.e. intramuscular (IM), some AEs, local and/or systemic AEs, were expected and solicited within 7 days after study Investigational Medicinal Product (IMP) administration.

Substantial protocol amendments (globally) |

| Were there any global substantial amendments to the protocol? Yes | |||
Date |
Amendment |

11 Aug 2015 |
Amendment #1 (dated 11 August 2015): it amended the protocol Version 2.0 into protocol Version 3.0 as per request of the European Health Authorities. This amendment introduced and update of the promary objective to:
- The primary objective of this study is to evaluate the neutralization of the IFN gene signature following treatment with IFN-K, as measured by the change from baseline of the expression of IFN-induced genes and to evaluate the efficacy of treatment with IFN-K using the British Isles Lupus Assessment Group (BILAG)-based Composite Lupus Assessment (BICLA) response criteria. |
||
08 Dec 2015 |
Amendment #2 (dated 08 December 2015), amending the protocol Version 3.0 into protocol Version 4.0, introduced the following modifications:
- Addition of the extended follow-up within the IFN-K-002 protocol rather than in a separate protocol: the protocol Version 4.0 therefore integrated an extended follow up period up to a total duration of 5 years (60 months, i.e. 240 weeks) after the last visit of the main study (Visit 12 at week 36). The visit at week 276 (Month 69), i.e. FU10, was then considered as the last planned visit.
- complete extended follow-up only for some subjects receiving the active treatment: due to the double-blind study design, all subjects who had completed the main study (up to Visit 12 at week 36) would enter into the extended follow-up period. When the results would be available, only subjects having received IFN-K and having produced anti-IFN-alpha antibodies (neutralizing) would continue the extended follow up. Subjects would remain into the extended follow-up period until they become negative for anti-IFN-alpha neutralizing antibodies or for up to 5 years (60 months, i.e. 240 weeks) after Visit 12, whichever comes first.
- frequency of visits during the extended follow-up: subjects would be followed every 6 months, as in the IFN-K-001 study.
- regular analyses: for safety purpose, a descriptive analysis would be performed at regular intervals, according to DSUR timelines.

28 Jan 2016 |
Amendment #3 (dated 28 January 2016), amending the protocol Version 4.0 into protocol Version 5.0, introduced the following modifications:
- Expansion of geographic areas for the study conduct: worldwide epidemiology studies reported large variations in incidence and prevalence of SLE, reflecting influences of race, ethnicity and socio-economic status; in addition, several studies have demonstrated an overexpression of IFN-alpha inducible genes in SLE subjects and a possible correlation between their expression and the disease activity notably the serological markers. The study being originally planned to be conducted in 3 geographic areas (Europe, Asia-Pacific and Latin-America), the protocol was amended to expand the study to the USA to provide results on an overall population and better cover the specificities of the different ethnicities.
- The relationship between the ethnicity and the expression of the IFN gene signature was taken into account in the randomization (minimization factor) and the sample size calculation was revised to ensure statistical power on the primary endpoints.

11 Apr 2016 |
Amendment #4 (dated 11 April 2016), amending the protocol Version 5.0 into protocol Version 6.0, introduced the following modifications:
- Complete extended follow-up only for all subjects receiving the active treatment: as requested by Food and Drug Administration (FDA), all subjects having received IFN-K would be followed up for up to 60 months, irrespective of the production of anti-IFN-alpha antibodies at Visit 12 (Week 36) and during the whole extended follow up period.
- Modification of inclusion criterion #8: as requested by FDA, the time on treatment and time on stable dose has been increased to 12 weeks prior to study product injection for subjects taking Methotrexate (MTX), Azathioprine (AZA) and Mycophenolate Mofetil (MMF).
- Modification of exclusion criterion #11 for US subjects only: as requested by FDA, only subjects with negative screening tests for malignancy according to the American Cancer Society (ACS) guidelines within 12 months before screening Visit could be enrolled; in addition, for subjects with history of treated cancers, only treated basal cell carcinoma was not preventing enrollment.
- Modification of an event leading to study product dicontinuation: as requested by FDA, “the occurrence of bronchospasm after administration of study product must be considered as a criterion for study product discontinuation” was revised as “bronchospasm or anaphylactic reaction following the administration of the study product”.
- Modification is AE reporting: since not all countries have the same requirements for reporting of fatal, life-threatening events and all other SAEs to Regulatory Health Authorities, the possibility to follow local requirements was added.
|

15 May 2017 |
Local amendment (amendment #5) for Argentina (dated 15 May 2017), amending the protocol Version 5.0 into protocol Version 6.1: per request of the Argentinian Health Authority, the following modifications have been made:
- Modification of exclusion criterion #11 for: “history of malignant cancer, except the following treated cancers: basal cell carcinoma or dermatological squamous cell carcinoma”.
- Modification of exclusion criterion #23 for: “cytological abnormalities ≥LSIL (low grade squamous intraepithelial lesions) on a cervical swab at Screening or within 3 months prior to the first planned study product administration”.
- Addition of clarification to inclusion criterion #9.
- Addition of clarification to exclusion criterion #1.
