A Study Comparing 2 Doses Of CP-690,550 Vs. Placebo For The Treatment Of Rheumatoid Arthritis In Patients On Other Background Arthritis Medications
torstai 6. joulukuuta 2012 päivittänyt: Pfizer
Phase 3, Randomized, Double Blind, Placebo Controlled Study Of The Safety And Efficacy Of 2 Doses Of CP 690,550 In Patients With Active Rheumatoid Arthritis On Background DMARDS
This Phase 3 study is intended to provide evidence that CP-690,550 dosed 5 mg BID and 10 mg BID is safe and effective when used in combination with a variety of traditional disease modifying antirheumatic drugs in adult patients with rheumatoid arthritis.
It is intended to confirm the benefits of CP-690,550 in improving signs and symptoms and physical function that were observed in the Phase 2 rheumatoid arthritis studies.

Terveysarviokyselyn vammaisuusindeksin (HAQ-DI) pistemäärän muutos lähtötasosta 3. kuukaudessa
Aikaikkuna: Perustaso, kuukausi 3
|
HAQ-DI: osallistujien raportoima arvio kyvystä suorittaa tehtäviä kahdeksassa arkielämän toimintokategoriassa: pukeutuminen/sulhasen;nouseminen;syöminen; kävellä;ulottaa;ote; hygienia; yhteiset toimet viime viikolla.
Jokainen kohta pisteytettiin 4 pisteen asteikolla 0-3:0 = ei vaikeuksia; 1 = jonkin verran vaikeuksia; 2 = paljon vaikeuksia; 3 = ei pysty tekemään.
Kokonaispisteet laskettiin verkkotunnuspisteiden summana ja jaettuna vastattujen verkkotunnusten lukumäärällä.
Mahdollinen kokonaispistemäärä 0-3:0 = pienin vaikeusaste ja 3 = äärimmäinen vaikeusaste.
CP-690 550:n vertaamiseksi lumelääkkeeseen plasebosekvenssit yhdistettiin yhdeksi raportointiryhmäksi kuukauden 3 analyysiä varten.

DAS28-4 (ESR) was calculated from SJC and TJC using 28 joints count, erythrocyte sedimentation rate (ESR) (millimeters/hour[mm/hour]) and patient's global assessment (PtGA) of disease activity(participant rated arthritis activity assessment).
Total score range:0-9.4,
higher score=more disease activity.
DAS28-4 (ESR) less than or equal to (<=)3.2 implied low disease activity, greater than (>)3.2 to 5.1 implied moderate to high disease activity, less than (<)2.6=remission.
For comparison of CP-690,550 with placebo, placebo sequences were combined into single reporting group for Month 6 analysis.

36-kohtainen lyhytmuotoinen terveyskysely (SF-36) lähtötilanteessa, kuukausina 1, 3 ja 6
Aikaikkuna: Perustaso, kuukausi 1, 3, 6
|
SF-36 on standardoitu tutkimus, jossa arvioidaan 8 toiminnallisen terveyden ja hyvinvoinnin näkökohtaa: fyysinen toiminta, fyysinen rooli, kehon kipu, yleinen terveys, elinvoimaisuus, sosiaalinen toiminta, rooli emotionaalinen ja mielenterveys.
Osion pisteet ovat yksittäisten kysymyspisteiden keskiarvo, jotka skaalataan 0-100 (100 = korkein toimintataso) ja raportoidaan 2 yhteenvetopisteenä; fyysisen komponentin pistemäärä ja henkisen komponentin pistemäärä.
Yhteenvetopisteiden kokonaispistemäärä = 0-100, jossa korkeampi pistemäärä edustaa korkeampaa toimintatasoa.

Osallistujien arvioima 12 kohdan kyselylomake viime viikon unen rakenteiden arvioimiseksi.7 alaasteikkoa: unihäiriöt, kuorsaus, herännyt hengenahdistus, unen riittävyys, uneliaisuus (vaihteluväli: 0-100); unen määrä (alue: 0-24), optimaalinen uni (kyllä tai ei).
9 kohdeindeksimittaukset unihäiriöistä tarjoavat yhdistelmäpisteitä: uniongelmien yhteenveto, yleinen uniongelma.
Paitsi Riittävyys, Optimaalinen, Unen määrä, korkeammat pisteet = enemmän heikkenemistä.
Muunnetut pisteet (todellinen raakapistemäärä(RS) miinus matalin mahdollinen pistemäärä jaettuna mahdollisella RS-alueella*100);kokonaispistemäärä: 0-100, korkeampi pistemäärä = attribuutin intensiteetti.

|
MOS-SS: osallistujien arvioima 12 kohdan kyselylomake unen rakenteiden arvioimiseksi kuluneen viikon aikana.
Se sisälsi 7 ala-asteikkoa: unihäiriöt, kuorsaus, herännyt hengenahdistus, unen riittävyys, uneliaisuus, unen määrä ja optimaalinen uni.

Kroonisten sairauksien terapian (FACIT) toiminnallinen arviointi – väsymysasteikko lähtötilanteessa, kuukaudet 1, 3 ja 6
Aikaikkuna: Perustaso, kuukausi 1, 3, 6
|
FACIT-Fatigue on 13 kohdan kyselylomake.
Osallistuja pisteytti jokaisen kohdan 5 pisteen asteikolla: 0 (ei ollenkaan) 4 (erittäin paljon).
Mitä suurempi osallistujan vastaus kysymyksiin (lukuun ottamatta kahta negatiivista vastausta), sitä suurempi on väsymys.
Kaikille kysymyksille, lukuun ottamatta kahta negatiivista vastausta, koodi käännettiin ja uusi pistemäärä laskettiin 4 miinus osallistujan vastaus.
Kaikkien vastausten summa johti FACIT-väsymyspisteeseen mahdolliseksi kokonaispistemääräksi 0 (huonompi pistemäärä) 52 (parempi pistemäärä).
Korkeampi pistemäärä heijasti osallistujan terveydentilan paranemista.

Euro Life Quality of Life (EQ-5D) – Terveystilan profiilin hyödyllisyyspisteet lähtötilanteessa, kuukausi 3 ja 6
Aikaikkuna: Perustaso, kuukausi 3, 6
|
EQ-5D: osallistujien arvioima kyselylomake terveyteen liittyvän elämänlaadun arvioimiseksi yhdellä hyödyllisyyspisteellä.
Health State Profile -komponentti arvioi nykyisen terveyden tason viidellä alueella: liikkuvuus, itsehoito, tavalliset toiminnot, kipu ja epämukavuus sekä ahdistus ja masennus; 1 tarkoittaa parempaa terveydentilaa (ei ongelmia); 3 tarkoittaa huonointa terveydentilaa ("suljettu sänkyyn").
EuroQol Groupin kehittämä pisteytyskaava määrittää kullekin profiilin verkkotunnukselle hyödyllisyysarvon.
Pisteet muunnetaan ja tuloksena on kokonaispistemäärä -0,594 - 1,000; korkeampi pistemäärä tarkoittaa parempaa terveydentilaa.

Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue Scale at Month 12
Aikaikkuna: Month 12
|
FACIT-Fatigue is a 13-item questionnaire.
Participant scored each item on a 5-point scale: 0 (Not at all) to 4 (Very much).
The larger the participant's response to the questions (with the exception of 2 negatively stated), the greater the fatigue.
For all questions, except for the 2 negatively stated ones, the code was reversed and a new score was calculated as 4 minus the participant's response.
The sum of all responses resulted in the FACIT-Fatigue score for a total possible score of 0 (worse score) to 52 (better score).
A higher score reflected an improvement in the participant's health status.
