|
|
E.4 | Principal exclusion criteria |
1) Optic neuritis relapse within the three months before inclusion 2) Normal RNFL at OCT 3) Presence of other ocular pathology (glaucoma, cataract, retinopathy, anterior uveitis, myopia>7 dioptrics, intraocular pressure>20, amblyopia, retinal or optic head abnormalities (drusen, dysversion) 4) Bilateral visual acuity <1/20 5) Visual impairment caused by ocular flutter or nystagmus 6) Pregnancy or childbearing potential woman without contraception: - Both male and female subjects who are not either surgically sterile (tubal ligation/obstruction or removal of ovaries or uterus) or post-menopausal (no spontaneous menstrual periods for at least one year confirmed by a negative hormone panel) must commit to using TWO highly effective method of birth control for the duration of the study and for two months after the treatment termination. A highly effective method of birth control is defined as those which result in a low failure rate (i.e., less than 1% per year) when used consistently and correctly such as implants, injectable or combined oral contraceptives, IUDs, sexual abstinence or vasectomized partner. Acceptable forms of effective contraception include: - Established use oral, injected or implanted hormonal methods of contraception. - Placement of an intrauterine device (IUD) or intrauterine system (IUS). - Barrier methods of contraception: Condom or Occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/suppository. Notice that, when used alone, the diaphragm and condom are not highly effective forms of contraception. - The use of additional spermicides does confer additional theoretical contraceptive protection. Spermicides alone are inefficient at preventing pregnancy when the whole ejaculate is spilled. Therefore, spermicides are not a barrier method of contraception and should not be used alone. - True abstinence: When this is in line with the preferred and usual lifestyle of the subject. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception. - Male sterilisation: subjects must present with the appropriate post-vasectomy documentation of the absence of sperm in the ejaculate. For female subjects on the study, the vasectomised male partner should be the sole partner for that subject. 7) Any general chronic handicapping disease other than MS 8) New treatment introduced less than 3 months prior to inclusion or less than 1 month for Fampridine |
1) Rechute de névrite optique dans les 3 mois précédant l'inclusion 2) Couche des fibres nerveuses de la rétine normale sur l'OCT 3) Presence d'autre maladie ophtalmique (glaucome, cataract, retinopathie, uveite anterieure, myopie > 7d, pression intra-oculaire >20, amblyopie, anomalies de la rétine ou de la papille optique (drusen, dysversion papillaire...) 4) Acuité visuelle bilaterale < 1/20 5) Baisse de l'acuité visuelle en rapport avec un nystagmus ou un flutter oculaire 6) Grossesse ou femme en age de procreation sans double contraception efficace : les hommes et les femmes qui ne sont pas stériles ou qui ne sont pas en période post ménopausique doivent utiliser deux méthodes de contraception efficaces. Ces méthodes incluent la contraception orale (pilules contraceptives), un dispositif intra-utérin (stérilet), l’abstinence sexuelle, la vasectomie, l’utilisation de diaphragmes avec spermicides et l’utilisation de préservatifs. Noter que l’utilisation de préservatifs ou d’un diaphragme avec spermicide ne sont pas des méthodes suffisamment efficaces si elles sont utilisées seules. L’abstinence périodique (par exemple en fonction du calendrier d’ovulation ou de la courbe thermique), ainsi que le retrait (coït interrompu) ne sont pas des méthodes efficaces de contraception. 7) Maladie avec handicap neurologique autre que la sclérose en plaques 8) Introduction d'un nouveau traitement dans les 3 mois précédents l'inclusion, ou dans le mois précédent pour la fampridine |

E.5 End points |
E.5.1 | Primary end point(s) |
Mean change in best corrected visual acuity (logMAR) at 100% contrast between baseline and month 6 of the diseased eye (where the diseased eye is defined as the eye with the worst visual acuity (<5/10) at baseline and with evidence of worsening during the past three years) |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Selection visit M-1, Inclusion visit M0, Interim visit M3, End of blinded period visit M6, Interim visit M9, Interim visit M12 Interim visit M18 Biannual follow-up visits |

E.5.2 | Secondary end point(s) |
1. A Fisher’s exact test will be used to compare the proportions of patients with improvement of VA of the diseased eye of at least 0.3 logMAR at M6 2. A Fisher’s exact test will be used to compare the proportions of patients with improvement of bilateral AV from <5(70 ETDRS visual acuity score) to ≥5/10 (70 visual acuity score)) at 100% contrast at M6 3. A logistic model using a generalized estimating equations (GEE) approach will be used to compare the proportions of eyes with reappearance of P100 waves or improvement of P100 latencies≥10 ms at M6 4. Mann-Whitney’s U test will be performed to compare the mean values of CGI at M6 (clinical global impression evaluated by the patient (SGI) and by the clinician (CGI), 5. Mann-Whitney’s U test will be used to compare the mean change in NEIFVQ-25 (functional vision questionnaire) between baseline and M6, 6. Mann-Whitney’s U test will be used to compare the mean change in the SF36 subscores between baseline and M6
In addition, the following endpoints will be used as exploratory endpoints to provide additional support.
End of the placebo-controlled period at M6: - The proportion of patients with improvement of VA of the selected eye of at least 0.1 and 0.2 logMAR at 100% contrast at M6 will be displayed by treatment group. A Fisher’s exact test will be used to compare the proportions of patients with improvement of VA of the selected eye of at least 0.1 and 0.2 logMAR at M6. - Mean changes in visual acuity of the non-selected eye between M0 and M6 at 100% contrast. An ANCOVA on mean changes with adjustment on visual acuity at baseline will be performed as well as a Welch t-test and a Wilcoxon-Mann-Whitney test; - Mean changes in visual acuity of all eyes between M0 and M6 at 100% contrast. A generalized estimating equations (GEE) approach will be performed; - Mean change in bilateral visual acuity at 100% contrast between baseline and M6 (M12 and M18 for the extension phase). An ANCOVA on mean changes with adjustment on visual acuity at baseline will be performed - Mean change in visual acuity of the selected eye at 5% contrast between baseline and M6 (M12 and M18 for the extension phase). An ANCOVA on mean changes with adjustment on visual acuity at baseline will be performed as well as a Welch t-test and a Wilcoxon-Mann-Whitney test. - Mean change in visual acuity of all eyes at 5% contrast between baseline and M6 (M12 and M18 for the extension phase). LogMAR at 5% contrast as well as mean changes in visual acuity of all eyes between baseline and M6 will be summarized by treatment group. A GEE model will be also performed adjusting on center and baseline values. - The proportion of patients with at least one eye improved by at least 0.3 logMAR at 5% contrast at M6 will be displayed by treatment group. A Fisher’s exact test will be used to compare the proportions of patients with at least one eye improved by at least 0.3 logMAR at 5% contrast at M6. The same analyses will be performed other cut off values of 0.1 and 0.2 logMAR. - Mean changes in the mean deviation visual field defects of the selected eye between baseline and M6 will be summarized by treatment group. An ANCOVA on mean changes with adjustment on baseline values will be performed. - Mean changes in the mean deviation visual field defects of all eyes between M0 and M6 (generalized estimating equations (GEE) approach); - Mean changes in the Pattern Standard Deviation between M0 and M6 (generalized estimating equations (GEE) approach); - Mean changes in RNFL values of all eyes between baseline and M6 (generalized estimating equations (GEE) approach); - Mean changes in temporal RNFL values of all eyes between baseline and M6 (generalized estimating equations (GEE) approach); - Mean changes in macula volume between baseline and M6 (generalized estimating equations (GEE) approach); - Mean changes in selected latencies of all eyes between M0 and M6 will be compared between the treatment groups using a GEE approach with adjustment on baseline values. Mean changes between M0 and M12 will be also described by treatment group. - Mean changes in selected amplitudes of all eyes between M0 and M6 will be compared between the treatment groups using a GEE approach with adjustment on baseline values. Mean changes between M0 and M12 will be also described by treatment group. |
