Възможност за продължаване на лечението на HBeAg отрицателни пациенти!

[Емануил Денков]

 Здравейте приятели,
за много години! Искам да споделя нещо на което попаднах! Не знам колко е актуално но попаднах на тази информация:

Long Term Treatment with Pegasys in HBeAg-negative Patients - Bulgaria
Evaluate the efficacy and safety of intermittent treatment with PEGASYS in HBeAg negative patients who have demonstrated response after treatment with interferon alfa. Contact Hoffmann-La Roche: 973-235-5000 (Please reference Study ID Number: RLI_ML20020).

Ако някой го попада в тези критерии и иска да се лекува час по-скоро да се обади на черния номер с код за САЩ!

Поздрави,
Емо

Здравей, Емо!

Информацията е актуална! На мен ми предложиха да ме включат в това клинично проучване след като завърших лечението с интерферон. Има определени изисквания, за да може да се включи пациентът - при първоначалното лечение трябва да е имал негативен HBV-DNA тест в края на третия месец и в края на лечението също да има отрицателен HBV-DNA. Три месеца след прекратяване на лечението също се прави HBV-DNA и ако и тогава копията на вируса са HBV DNA <100,000 copies/mL, могат да те включат във въпросното проучване. Терапията е в продължение на 2 години, като дозите са намалени - 135 микрограма. Три месеца си с интерферон, а следващите три месеца почиваш и т. н. Проучването е за пациенти с отрицателен HBeAg антиген. На 06-01-2009 отивам да ми направят HBV-DNA и в зависимост от това какъв е резултата ще се реши дали ще участвам в проучването или не. Ако ме включат ще ви информирам за подробности!
Всъщност става въпрос за продължаване на едногодишното лечение с още 2 години, а не за включване на нови пациенти на лечение с интерферон.

SOFIA-LTT Study: A Study of Intermittent Long Term Treatment With PEGASYS (Peginterferon Alfa-2a (40KD)) in Patients With HBeAg Negative Chronic Hepatitis B (CHB).
This study is currently recruiting participants.
Verified by Hoffmann-La Roche, December 2008
Sponsored by:    Hoffmann-La Roche
Information provided by:    Hoffmann-La Roche
ClinicalTrials.gov Identifier:    NCT00442572
  Purpose

This 2 arm study will evaluate the efficacy and safety of intermittent treatment with PEGASYS in HBeAg negative patients with chronic hepatitis B who have demonstrated virological and biochemical response after treatment with interferon alfa. After 48 weeks therapy with interferon alfa, and 24 weeks treatment-free follow-up, eligible patients will be randomized into the PEGASYS or the observational group. Those in the PEGASYS group will receive 4 therapeutic cycles of long term intermittent treatment with PEGASYS (135 micrograms sc weekly for 12 weeks, followed by a treatment-free period of 12 weeks) and those in the observational arm will receive no specific antiviral treatment. The anticipated time on study treatment is 1-2 years, and the target sample size is 100 individuals.
