Other dsRNAs can be used for the invention, in particular a complex of polyinosinic acid with polycytidylic acid, also known as poly (I) -poly (C), as well as these same complexes modified by the introduction of uridic acid within the chain of polycyclic acid, such as the product Ampligen® manufactured by the company HEMISPHERx (for a description of these products see in particular European Patent Application EP-0, 300, 580). The dsRNA used can be, for example, a mixture of dsRNAs as defined above. The dsRNAs are preferably prepared according to the procedure described in French Patent No. 2, 622, 586. In the present application, the term "antiviral agent" is understood to mean an agent acting directly on the virus, such as ribavirin. or lamivudine, and an immunomodulatory agent, for example an agent that weakens or strengthens immune defenses, such as cyclosporin or an interferon.The antiviral agents combined with the dsRNA can be chosen, for example, from an interferon, such as interferons a , ß or? or consensus interferons, and in particular, an interferon-a (INF-a), other lymphokines, such as interleukins, for example IL6 or IL9, ganciclovir, cumermicin Al, lamivudine, ribavirin, vidarabine, dideoxyinosine (DDI) ), azathioprine, prednisolone or cyclosporine.Preferably, the antiviral agent combined with the dsRNA will be an interferon.An interferon is understood to be one or more interferons to different, such as for example Interferons a-2a, a-2b, a-2c, a-ni, a-n3, or any other analog that has comparable immunological properties. By a consensus interferon is understood, for example, the interferons INF-conl, INF-con2 and INF-con3 (these consensus interferons are described in particular in U.S. Patent No. 5,372,808 and in PCT / O Patent Application 93 / 21229). By simultaneous therapeutic use is meant in the present Application, an administration of more active ingredients by the same route and at the same time. By separate use is meant, in particular, an administration of several active ingredients at about the same time by different routes. By therapeutic administration over a period of time it is understood the administration of several
é? active ingredients at different times and in particular a method of administration to which the entire administration of one of the active ingredients is completed, before the administration of the other or of the others begins. In this way it is possible to administer one of the active ingredients for several months before administering the other or other active ingredients. In this case, simultaneous administration does not occur. Viral disease is understood in particular as viral hepatitis, and in particular hepatitis B or hepatitis C. Viral hepatitis treated with the product according to the invention may be chronic or acute in nature. Preferably, the product according to the invention is intended for chronic hepatitis. The invention in particular relates to a product that is characterized in that it comprises: i) a dsRNA in combination with: n) an antiviral agent, for prolonged therapeutic use over a period of time, in the treatment of a viral disease. Preferably, the use of the dsRNA takes place before the antiviral agent.
According to a preferred variant of the invention, the invention relates to a product that is characterized in that it comprises: i) a dsRNA in combination with ii) an interferon for prolonged therapeutic use over a period of time in the treatment of a disease viral. Preferably, the use of dsRNA takes place before the inferred. Preferably the interferon used will be interferon a. According to a particular aspect of the invention, the product contains at least one dsRNA in combination with at least one antiviral agent, which can be a mmunomodulatory agent and is characterized in that it also contains at least one antiviral agent that acts directly on viruses for the simultaneous or separate use with the immunomodulatory agent or agents in the treatment of a viral disease. Preferably, the immunomodulatory agent (s) are interferons. According to another variant of the invention, the product containing at least one dsRNA in combination with at least one antiviral agent is characterized in that it also contains at least one antiviral agent for therapeutic use that is
extends over a "" period of time, and that takes place before the dsRNA in the treatment of a viral disease. Among the others, antiviral Uagents which can be used for this particular variant of the invention, there can be mentioned lymphokines different from interferons such as the methylleucins, for example, IL-6 or IL-9, ganciclovir, cumermicin Al, lamivudine, ribavirin, vidarabine, dideoxyinosine (DDI), azathioprine, prednisolone or cyclosporine. More particularly, the invention relates to a product characterized in that it comprises: i) an antiviral agent in combination with li) a dsRNA, and in) an inferred, which may be simultaneously or separately combined with an antiviral agent that acts directly on the viruses, for an administration that is separated in time and carried out in the order indicated above in the treatment of a viral disease, in particular hepatitis B. The various sequences of administration of the dsRNA and the antiviral agent can be considered. According to a particular method of + - &
the invention, the dsRNA and the antiviral are not administered simultaneously. Preferably, the dsRNA is administered before the antiviral agent with which it is combined. The treatment with the dsRNA preferably extends over a period of 1 to 12 months or more, for example 6 months, and followed by administration of the antiviral agent in an equivalent or different period of time. An object of the invention is also pharmaceutical compositions containing, as an active ingredient, a product according to the invention, for example a product containing at least one dsRNA in combination with at least one antiviral agent, preferably an interferon, in combination with excipients or supports suitable for therapeutic use simultaneously, separately or in a period of time, in the treatment of viral diseases. Preferably, the viral disease treated by the pharmaceutical products and the compositions according to the invention will be viral hepatitis, such as hepatitis A, B, C or G or hepatitis' not A, not B, not C, not G " for example hepatitis of a different type to types A, B, C or G.

doses The product can be administered daily or several times a week. For example, a dose of between 15 mg and 1.5 g can be administered, preferably of the order of 50 to 300 mg two or three times per week. The dose of interferon will in theory be that usually used by a person skilled in the art, and preferably between 0.5 and 60 million international units per dose. In the case of INF-a, for example, the dose may be
between 1 and 50 million units, preferably between 1 and 10, and in particular between 3 and 6 million units. In addition, the administration can be daily or take place several times a week. In particular, two or more may be administered per week
three administrations. For example, it is possible
Choose to manage between 3 and 6 million units two or three times a week. According to another variant of the invention, it is also possible to precede the treatment with dsRNA by a treatment with an antiviral agent. For example, an interferon, lamivudine or ribavirin could be administered during the first period, the dsRNA during a second period and finally during a third period, an interferon optionally combined with at least one antiviral agent, such as ribavirin or lamivudine. The interferon used for the treatment will preferably be an INF-a. To choose the methods and dosage of administration, a person skilled in the art could also usefully consult the following article (and the references cited therein): Daniel Dhumeaux, La rev? E du pra ct i ci en, 45 pp. 2519-2522 (1995).

Clinical properties of the products according to the invention
Example 1
A group of ten patients suffering from hepatitis C was treated successively with poly (A) poly (U) and then with interferon. The treatment was carried out as follows: initially, patients received two weekly administrations of a 150 mg dose of poly (A) poly (U) administered by the intravenous route for 24 weeks; After this initial treatment, patients received a dose of 3 million units of interferon, administered by the intravenous route 3 times per week for 24 weeks. After this two-stage treatment, a remission of the disease was observed in 6 of the patients, a remission followed by a relapse in a seventh patient and the treatment had no effect only in three of the patients.
? ? "A» r
By way of comparison, a treatment consisting of interferon alone, produced remission in only 20% to 30% of the treated cases (see Daniel Dhumeaux, La revue du pra cti ci en, 45 PP 2519- 5 2522 (1995).
Example 2
Two groups of patients suffering from
chronic active hepatitis B, the first group consisting of 42 patients (group A), the second group consisting of 44 patients (group B) received the following treatments, starting on the same date: 15 - patients in group A received a dose of 150 mg of poly (A) -poly (U) administered by the intravenous route twice a week for 24 weeks, and then a dose of 6 million units of INF-a administered by the route
Subcutaneously, 3 times a week for the next 24 weeks; patients in group B did not receive treatment for the first 24 weeks and then received 6 million units of INF-a
üs ^ y¡XhMtí L? &. ^ ..
administered by the subcutaneous route 3 times a week for the next 24 weeks. The presence of HBV virus DNA and a serum HBe test were determined 24, 48 and 72 weeks after the date when treatment with poly (A) -poly (U) was started. The results, expressed in terms of the percentage of patients who responded to the treatment, are summarized in the following table:
+ P 0.001 p = 0.02 p = 0.006
Conclusion: in patients suffering from chronic, active hepatitis B, pretreatment with poly (A) -poly (U) before treatment with INF-a had the result of increasing the proportion of response to treatment for 6 months with INF- a and reduced the number of relapses after this treatment.
It is noted that in relation to this date, the best method known to the applicant to carry out the aforementioned invention, is that which is clear from the present description of the invention.
