Description
Anwendungsgebiet der ErfindungField of application of the invention
Die Erfindung betritft ein Verfahren zur Herstellung von Vakzinen mit erhöhter Wirksamkeit, die im Bereich der Human- oder Veterinärmedizin, der Pharmazie sowie in dor Landwirtschaft (Tierproduktion) angewendet werden können.The invention relates to a process for the production of vaccines with increased efficacy, which can be applied in the field of human or veterinary medicine, pharmacy and in agriculture (animal production).
Charakteristik des bekannten Stande» der TechnikCharacteristics of the known state of the art
Es ist bekannt, daß viele Virus- odnr Bakterienantigene bei Injektion in einen Organismus keine meßbare oder nur eine geringe Immunantwort auslösen, so daß sie nicht ohne weiteres als Impfstoff verwendet werden können. Die antigene Wirksamkeit von viralen oder bakteriellen Materialien kann jedoch durch Zugabe von Adjuvantien verstärkt werden. In der Literatur sind zahlreiche Stoffe vorgeschlagen worden, die als Adjuvantien verwendet werden können. Am gebräuchlichsten sind bisher Aluminiumhydroxid, mineralische und pflanzliche Öle und Stoffwechselprodukte von Bakterien (THEIN, Vet. Med. Nachr. 59 [1988]). Sehr gute Adjuvanswirkungen werden durch Emulgieren von wäßrigen Antigenlösungen mit Mineral-oder Pflanzenölen erreicht. Solcho Emulsionen, besonders Mineralölemulsionen, werden jedoch lokal schlecht vertragen. Nach Impfungen von Ölemulsionsvakzinen können makroskopische Veränderungen an den Impfstellen bis zur 28.1 ebenswoche post vaccinationem wahrgenommen werden, was aus fleischbeschaulichen Gründen bei Nutztieren zu Reglementierungen führen kann. Weiterhin sind Ölemulsionsvakzinen verhältnismäßig viskos, wodurch der Umgang mit ihnen erschwert ist. Außerdem benötigt man für die Öle geeignete spezifische Emulgatoren.It is known that many viral or bacterial antigens when injected into an organism do not elicit a measurable or only a slight immune response, so that they can not readily be used as a vaccine. However, the antigenicity of viral or bacterial materials can be enhanced by the addition of adjuvants. Numerous substances have been proposed in the literature which can be used as adjuvants. The most commonly used so far are aluminum hydroxide, mineral and vegetable oils and metabolites of bacteria (THEIN, Vet. Med. Nachr. 59 [1988]). Very good adjuvant effects are achieved by emulsifying aqueous antigen solutions with mineral or vegetable oils. However, Solcho emulsions, especially mineral oil emulsions, are poorly tolerated locally. After vaccination of oil emulsion vaccines, macroscopic changes at the injection sites can be detected up to 28.1 weeks post vaccinationem, which may lead to regulations for meat-producing reasons in livestock. Furthermore, oil emulsion vaccines are relatively viscous, which makes handling them difficult. In addition, suitable for the oils suitable emulsifiers.
Unbefriedigend bei den meisten bekannten Adjuvantien ist allgemein ihre oft nur geringe Wirksamkeit oder eine ungenügende physiologische Verträglichkeit.Unsatisfactory with most known adjuvants is generally their often poor efficacy or inadequate physiological compatibility.
Ziel der ErfindungObject of the invention
Das Ziel der Erfindung besteht daher darin, der pharmazeutischen Industrie zu human- oder veterinärmedizinischen Zwecken Vakzinen zugänglich zu mac.' 'lie sich durch eine erhöhte Wirksamkeit und eine gute physiologische Verträglichkeit auszeichnen. Gleichzeitig ist cit>. pharmazeutisch-technische Aufwand ihrer Herstellung zu minimieren und eine gute Applizierbarkeit zu gewährleisten.The object of the invention is therefore to make available to the pharmaceutical industry for human or veterinary purposes vaccines. 'It was characterized by increased efficacy and good physiological tolerability. At the same time, cit>. pharmaceutical-technical effort to minimize their production and to ensure good applicability.
Darlegung des Wesens der ErfindungExplanation of the essence of the invention
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zu entwickeln, das mit Hilfe neuer Adjuvantien zu Vakzinen mit erhöhter Wirksamkeit führt, d.h. bei gleicher Antigenmenge eine bessere Immunisierung als ohne Adjuvans bzw. mit herkömmlichen Adjuvantien erfolgt.It is an object of the present invention to provide a method which results in improved efficacy vaccines with the aid of new adjuvants, i. For the same amount of antigen better immunization than without adjuvant or with conventional adjuvants.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, doß inaktivierte Virus- oder Bakterienmaterialien mit sterilisierten Lösungen von Polysaccharidderlvaten vermischt werden, die funktionell Gruppen der allgemeinen FormelAccording to the invention, the object is achieved by mixing inactivated virus or bacterial materials with sterilized solutions of polysaccharide derivatives which are functional groups of the general formula

tragen, wobei R1 = CH2, C2H4, R} = H, CH3, C1H6 und R3 = H, CH3, C2H6 bedeuten. Als Polysaccharidderivate können beispielsweise Produkte auf Basis von Cellulose, Hemicellulose, Agarose und Stärke verwendet wurden, wobei der Gehalt an funktionollen Gruppen pro Polysaccharidgrundbaustein 0,05 bis 1,0 betragen sollte. In besondernm Maße geeignet erwies sich dabei Diethylaminoethylcellulose. Der Polymerisationsgrad der erfindungsgemäßen Polysaccharidderivate kann in weiten Grenzen variiert werden, sollte jedoch 500 nicht überschreiten, damit die Viskosität der resulüerenden Vakzine nicht zu groß wird. Als günstig erwiesen sich Produkte mit einom Polymerisationsgrad zwischen 20 und 400, insbesondere jedoch zwischen 50 und 300. Für die Herstellung des Impfstoffes geht man vorteilhafterweise von einer 1 - bis 10%igen Lösung des Polysaccharidderivates in physiologischer Natriumchloridlösung aus, dio zunächst sterilisiert wird, beispielsweise durch Autoklavieren bei 1210C. Anschließend wird das inaktivierte Virus-oder Bakterienmaterial mit der Adjuvanslöiung in einem solchen Verhältnis vermischt, daß die Adjuvanskonzentration im Impfstoff 0,5 bis 5% beträgt. Die Applikation des Impfstoffes erfolgt in Dosen von 0,2 bis 2 ml, die jeweils 2 bis 20 mg Adjuvans enthalten. Die erfindungsgemäß hergestellten Impfstoffe zeichnen sich durch sehr gute allgemeine und lokale Verträglichkeit, gute Applizierbarkeit, eine hohe Antikörperbildung und damit auch hohe Schutzwirkung aus. Die vorgeschlagenen Adjuvantien sind durch eine verstärkende Wirkung des Antigens, Unschädlichkeit für den Impfling und einfache Zubereitung bzw. Anwendung charakterisiert.where R 1 = CH 2 , C 2 H 4 , R } = H, CH 3 , C 1 H 6 and R 3 = H, CH 3 , C 2 H 6 . For example, products based on cellulose, hemicellulose, agarose and starch may be used as polysaccharide derivatives, the content of functional groups per polysaccharide basic unit being 0.05 to 1.0. Diethylaminoethylcellulose proved to be especially suitable. The degree of polymerization of the polysaccharide derivatives according to the invention can be varied within wide limits, but should not exceed 500, so that the viscosity of the resulting vaccine does not become too large. For the production of the vaccine it is advantageous to proceed from a 1 to 10% solution of the polysaccharide derivative in physiological sodium chloride solution, the dio is first sterilized, for example by autoclaving at 121 ° C. Subsequently, the inactivated virus or bacterial material is mixed with the adjuvant solution in such a ratio that the adjuvant concentration in the vaccine is 0.5 to 5%. The vaccine is administered in doses of 0.2 to 2 ml, each containing 2 to 20 mg of adjuvant. The vaccines prepared according to the invention are distinguished by very good general and local compatibility, good applicability, high antibody formation and thus also high protective action. The proposed adjuvants are characterized by an enhancing effect of the antigen, innocuousness for vaccination and ease of preparation or use.
Zwar ist bekannt, daß verschiedene Polysaccharide immunstimulierende Eigenschaften besitzen, die vor allem auf dio β 1,3 und ß-1,6-Verknüpfungen von Glucosebsustoinen zurückgeführt werden, und auch bestimmte Voraussetzungen hinsichtlich Molekulargewicht und Löslichkeit gegeben sein müssen, doch war auf Grund dieser Kenntnisse nicht zu erwarten, daß die erfindungsgemäß als Adjuvantien vorgeschlagenen Polysaccharidderivate einen besonderen immunstimulieronden Effekt besitzen. Vielmehr hat sich gezeigt, daß vergleichsweise untersuchte Lösungen von Hydroxyethylcellulose und von Natriumcarboxymethylcnllulose keine positive Wirkung zeigenAlthough it is known that various polysaccharides have immunostimulatory properties, which are mainly attributed to dio β 1,3 and β-1,6 linkages of glucose, and must be given certain conditions in terms of molecular weight and solubility, but was due to this Knowledge can not be expected that the invention proposed as adjuvants polysaccharide derivatives have a special immunostimulating effect. Rather, it has been found that comparatively tested solutions of hydroxyethyl cellulose and Natriumcarboxymethylcnllulose show no positive effect
