FIELD OF INVENTION The present invention relates to field of live attenuated recombinant tetravalent dengue vaccines and methods of producing stable compositions. Present invention specifically relates to a stable composition and methods of using such a stable composition comprising live attenuated recombinant dengue virus, stabilizer, bulking agent and optionally buffering agents, wherein the live attenuated dengue virus is generated from A 30 and or A 31 deleted or mutated dengue strains. More specifically, the present invention relates to stabilizers for freeze-dried live attenuated immunogenic and/or vaccine compositions that may comprise, inter alia, dengue virus(es)! The invention further relates to stabilized, freeze-dried live attenuated immunogenic and/or vaccine compositions of, dengue virus(es), which may contain these stabilizers. Other aspects of the invention are described in or are evident from the following disclosure, and are within the ambit of the invention. BACKGROUND OF THE INVENTION Dengue virus (DENV) is a member of the Flavivirus genus of the Flaviviriade family which also includes yellow fever virus (YFV), West Nile virus (WNV), Japanese encephalitis virus (JEV) and tick-borne encephalitis virus. Flavivirus genome is single-stranded, positive-sense, RNA molecule of 11 kilobases containing single open reading frame. The RNA is translated into a polyprotein that is processed into at least 10 gene products: 3 structural proteins - Nucleocapsid or Core (C), Premembrane (prM), & Envelope (E) & 7 nonstructural (NS) proteins - NS 1, 2A, 2B, 3, 4A, 4B, & 5. There are four antigenically distinct serotypes (DENV 1-4) based on neutralization assay. All the serotypes are competent in causing asymptomatic manifestations as well as the more severe and fatal DHF and DSS. DENV is transmitted to humans mainly by Aedes mosquitoes (Aedes aegypti and Aedes albopictus). The prevalence of dengue disease is high especially in the Asia-Pacific region and the Americas. All four DENV serotypes are now circulating in these areas. With increased international travel and climate change, people are at risk of dengue infection beyond the traditional tropical and subtropical areas. Dengue disease is becoming one of the most important emerging vector-borne viral diseases. In the last 20 years dengue has spread rapidly and is endemic in more than 100 countries. An estimated 50 million dengue infection cases occur globally with around 500,000 cases of severe dengue and 20,000 deaths per year. Approximately, two-fifths of the world's population is at risk from dengue infection. Hence, the prevention and treatment of dengue fever is an important issue for the governments of many countries. Dengue has become a huge burden both in terms of lives lost, particularly, children and also the economic setback to the emerging economies of the world to contain the disease. A primary infection with any of the serotypes would induce lifetime immunity against that particular serotype but a subsequent infection with a different serotype can increase the severity of the disease due to a phenomenon known as antibody dependent enhancement (ADE). Hence development of an effective vaccine candidate catering to all the four serotypes, which would be safe and cost effective, is of great significance particularly for children and young adults who are the most susceptible. An ideal dengue vaccine should satisfy several factors to be commercially feasible. First, the vaccine must be protective against each of the four DENV serotypes to reduce the risk of ADE. Second, the immunization should be safe and not cause unacceptable side-effects caused by crossreactive antibodies or cross-reactive T cells. Third, the cost should be affordable to the individuals who most need the vaccines. There are still several obstacles for the development .of dengue vaccines. One is that the complicated pathogenesis is not fully understood. Another hindrance is the lack of suitable animal models. Currently there are no licensed vaccines available for dengue although there are vaccines available for a number of closely related viruses. The World Health Organization has prioritized the development of dengue vaccine and therapeutics for a long time. But so far due to unsuccessful development of any kind of vaccine or treatment for containing dengue, the arrangements so far pursued have been vector control and individual preventive steps which are tough to sustain and also expensive. The vector control programs are not sufficient to control the spread of the Dengue virus. In the absence of realistic alternatives, the development of a dengue vaccine has become a public health imperative. Similar to other viral vaccines, the success or failure of candidate dengue vaccines may well hinge on neutralizing antibody. Infection with a single DENV type results in a life-long antibody response and solid protection to challenge with the same virus type but still susceptible to other dengue serotypes. CD G) Q. CD CN O o Live attenuated vaccine development efforts are considered one of the effective approaches. A wild type dengue virus can be attenuated by serial passages in tissue culture to be used in humans maintaining its ability to generate an immune response. In another embodiment a chimeric vaccine candidate is generated by modification of a licensed yellow fever virus vaccine with dengue proteins. Another important feature of a live attenuated vaccine is its ability to induce sustained immune responses very closely mimicking a response in case of a natural infection. Several live attenuated dengue vaccine candidates have been developed and evaluated in humans or non-human primates. The first live attenuated dengue vaccine candidates were host range mutants developed by serial passage of wild type dengue viruses in the brains of mice and selection of mutants attenuated for humans (Kimura, R. & Hotta, S. 1944 Japanese J Bacteriology 1:96-99; Sabin, A.B. & Schlesinger, R.W. 1945 Science 101:640; Wisseman, C.L. Jr. et al. 1963 An J Trop Med 12:620- 623). Although these candidate vaccine viruses were immunogenic in humans, their poor growth in cell culture discouraged further development. Additional live attenuated DEN-1, DEN-2, DEN- 3, and DEN-4 vaccine candidates have been developed by serial passage in tissue culture (Angsubhakorn, S. et al. 1994 Southeast Asian J Trop Med Public Health 25:554-9; Bancroft, W.H. et al. 1981 Infect Immuno 31:698-703; Bhamarapravati, N. et al. 1987 Bull World Health Organ 65:189-95; Eckels, K.H. et al. 1984 Am J Trop Med Hyg 33:684-9; 15Hoke, C.H. Jr. et al. 1990 Am J Trop Med Hyg 43:219-26; Kanesa-thasan, N. et al. 2001 Vaccine 19:3179-88) or by chemical mutagenesis (McKee, K.T. Jr. et al. 1987 Am J Trop Med Hyg 36:435-42). It has proven very difficult to achieve a satisfactory balance between attenuation and immunogenicity for each of the four serotypes of dengue virus using these approaches and to formulate a tetravalent vaccine that is safe and satisfactorily immunogenic against each of the four dengue viruses (Kanesa-thasan, N. et al. 2001 Vaccine 19:3179-88; Bhamarapravati, N. & Sutee, Y. 2000 Vaccine 18 Suppl 2: 44-7). The goal of immunization is to protect against dengue virus disease by the induction of a long-lived neutralizing antibody response against each of the four serotypes. Simultaneous protection against E all four serotypes is required, since an increase in disease severity can occur in persons with preexisting antibodies to a heterotypic dengue virus. Such immunization can be achieved S economically with a live, attenuated virus vaccine. Applicants have successfully developed such a vaccine as reported in WO1993006214, WO2002095075, WO2003092592 and WO2008022196.

'^ strains was brought about by a novel 30 nucleotide deletion in the untranslated region at the 3' end of the viral genome. This deletion led to safe and complete attenuation of the virus strains with decreased viremia as observed in several studies in monkeys and humans (Phase I studies, with monovalent virus strains). Immunogenic compositions and vaccine compositions comprising biological ingredients, such as viruses, bacteria, parasites, fungi, proteins, polypeptides, glycoproteins, and especially, attenuated live microorganisms, are markedly sensitive to the conditions by which they are prepared, formulated and stored. Such biological ingredients can be modified and degraded by chemical reactions (e.g. hydrolysis, deamination, Maillard's reaction), many of which are mediated by water. Liquid water allows for molecular movements and can result in modification of protein conformations in compositions comprising biological ingredients. By limiting access to water or by removing water, a major factor of modification and degradation is reduced. Prior methods to confer stability to biological ingredients have primarily involved freezing the water or removing water by freeze-drying. Dengue viruses are basically thermo-labile in nature and lose infectivity upon exposure to. higher temperature. In. order to'maintain the viability of virus, ultra-storage (usually less that -60°C) is required. Storage at such a low temperature is not a favorable option in field condition due to supply chain related issues and higher cost associated with such storage temperatures. To be successful in field conditions, the vaccine needs to be stable at 2-8°C. In order to impart thermostability to virus, optimal quantity of various excipients, selected from the group of stabilizer, bulking agents, vehicle and buffering agents is required. Pivotal to the successful use and commercialization of vaccines is the manner by which they are processed and formulated, to ensure stability and maintenance of efficacy under conditions in which the vaccines are shipped and stored prior to use. Lyophilization is an approach involved in the processing of some vaccine products, and is essentially a freeze-drying process that, under low pressures, removes water through sublimation, and leaves the product as a dried cake with a small amount of moisture. This process can be advantageous to vaccines, including live attenuated dengue virus vaccines as described above, because such vaccines tend to be more stable in a low moisture environment. A critical factor impacting the efficacy of the Lyophilization process is the formulation of the vaccine. For example, it is desirable that the formulation, upon removal of water, enhances the stability of the product. Typically, a vaccine formulation will contain any or all of the following components: a bulking agent, a stabilizer, and optionally a buffer. The development of effective and efficient processing methods and formulations is therefore of great importance to the development of clinically useful and commercially successful vaccines, including live attenuated dengue vaccines. Despite advances in the area of vaccine formulations, there remains a distinct need for dengue live attenuated vaccine formulations with improved stability and shelf-life. None of the compositions known in prior art impart, the desired level of stability. The present invention addresses the unmet need for a live attenuated dengue vaccine formulation with increased stability.

The present invention further relates to a method of preventing or treating a disease or condition in a subject, the method comprising administering to the subject a composition comprising live, attenuated recombinant dengue virus, stabilizer, bulking agent and optionally buffering agents.

Lyophilization, or the process of freeze-drying, is a commonly used technique to remove water in the preparation of dehydrated products. Generally, "freeze-drying" an aqueous composition involves three steps. First, the aqueous composition is frozen under conditions of low temperature. Secondly, the frozen water is removed by sublimation under conditions of reduced pressure and low temperature. At this stage, the composition.usually contains about 15% water. Third, the residual water is further removed by desorption under conditions of reduced pressure and higher temperatures. At the end of the Lyophilization process, a freeze-dried product, also called a "pastille" or "cake" is produced. The freeze-dried product contains very low residual water (from about 0.2% to about 5% weight/weight) and dry material in a predominantly amorphous form. However, substantial loss of immunogenic activity of biological ingredients are observed during the preparation stages, such as before and during Lyophilization, and also during storage of immunogenic compositions and vaccine compositions. The integrity of biological ingredients must be safeguarded to ensure that the immunization efficiency of immunogenic compositions and vaccine compositions is retained. The immunogenic activity of biological ingredients is measured by the ability to induce and stimulate an immunologic response when administered to a host or subject. - 1 8 - ^ co Q . CD To limit the manipulation of subjects and the number of administrations, there is a strong need in the art to provide multivalent immunogenic compositions or vaccine compositions. By definition, a multivalent immunogenic composition or vaccine composition comprises more than one active immunogenic component originating from, or derived from, the same or at least two different pathogens. Viruses from different genera can vary in stability during the freeze-drying step and subsequent storage period, resulting in a loss of viability or infectivity. In the case of viruses such as dengue, the commonly administered active immunogenic components are live attenuated viruses. To efficiently stimulate the immune system, live attenuated viruses must replicate in the immunized subject. Loss of viability or infectivity can occur during the process of freeze-drying multivalent immunogenic compositions or vaccine compositions, during storage of the compositions, or before administration of the compositions after reconstitution. Thus, stabilizers have been added to such freeze-dried compositions. However, to obtain multivalent immunogenic compositions or vaccine compositions that retain their infectivity and/or viability, a stabilizer that is able to preserve viability and infectivity of different live attenuated pathogens would be particularly advantageous. Vaccine and immunogenic compositions have had a tremendous impact on public health by reducing morbidity and mortality from a variety of virulent pathogens. However, unintended side effects arising from additives in immunogenic compositions and vaccine compositions continue to pose a potential risk.that may outweigh any protective and therapeutic attributes of immunogenic compositions and vaccine compositions. The present invention addresses the need in the art by providing, inter alia, optimized formulations with stabilizers for freeze-dried live attenuated immunogenic compositions or vaccine compositions, which may comprise live attenuated recombinant dengue virus. These stabilizers may gj preserve viability and infectivity of these dengue viruses, notably during the freeze-drying process and during a long period of storage of the freeze-dried products at refrigerated temperatures and at room temperature for sufficient period of time to allow the short term excursion from cold chain. | Importantly, the presently claimed stabilizers for freeze-dried stabilized live attenuated o ^ immunogenic compositions or vaccine compositions of dengue virus are safe and suitable for CN injection to subjects after reconstitution. _ j LU Q CN CN CO CN CO CO CO o CN Q.
