BioHabana 2022: Preventive and Immunotherapeutic Strategies Against COVID-19 and Cancer in Cuba.

The convergence of life sciences with neurosciences, nanotechnology, data management, and engineering has caused a technological diversification of the biotechnology, pharmaceutical, and medical technology industries, including the phenomenon of digital transformation, which has given rise to the so-called Fourth Industrial Revolution (Industry 4.0). Confronting the COVID-19 pandemic revealed the outstanding response capacity of the scientific community and the biopharmaceutical industry, based on a multidisciplinary and interinstitutional approach that has achieved an unprecedented integration in the history of biomedical science.

Racotumomab in Non-Small Cell Lung Cancer as Maintenance and Second-Line Treatment.

Introduction: Racotumomab is a therapeutic vaccine based on a monoclonal anti-idiotypic antibody developed by the Molecular Immunology Center in Havana, Cuba, that is registered in Cuba and Argentina for treatment of non-small cell lung cancer. It induces a specific humoral and cellular immune response against the N-glycolyl GM3 (NeuGcGM3) ganglioside present in tumor cells, thereby provoking the death of these cells.

Objective: Evaluate racotumomab vaccine use as switch maintenance and second-line therapy for patients with inoperable non-small cell lung cancer in routine clinical practice, outside the framework of clinical studies, and assess the overall survival, stage-specific survival and safety in these patients.

Nimotuzumab for Patients With Inoperable Cancer of the Head and Neck.

EGFR activation induces cell proliferation, neoformation of blood vessels, survival, and metastasis of the cancer cells. Nimotuzumab is an engineered, intermediate affinity anti-EGFR antibody, that apart from other drugs in its class, is very safe and does not cause hypomagnesemia or grade 3-4 cutaneous rash. The antibody inhibits cell proliferation and angiogenesis, activates natural killer cells, stimulates dendritic cell maturation, and induces cytotoxic T cells.

HER1-based vaccine: Simultaneous activation of humoral and cellular immune response.

The human epidermal growth factor receptor 1 (HER1) is a tumor-associated antigen that has been validated as a clinical target for several passive, non-immune therapies currently approved for the treatment of epithelial tumors. HER1 is an oncogene that not only promotes tumor progression and survival, but also immune escape. Its overexpression in some epithelial malignancies has been correlated with a poor prognosis.

Pilot study of a novel combination of two therapeutic vaccines in advanced non-small-cell lung cancer patients.

Cancer vaccines contain tumor antigens in a pro-inflammatory context with the purpose to generate potent antitumor immune responses. However, tumor cells develop different immunosuppressive mechanisms that limit the effectiveness of an anticancer immune response. Therefore, therapeutic vaccine treatment alone is usually not sufficient to generate tumor regression or survival improvement, especially in the advanced disease scenario in which most clinical studies have been conducted.

Immunosenescence and gender: a study in healthy Cubans.

Background: The progressive decline in the immune function during ageing is termed immunosenescence. Previous studies have reported differences between males and females in the distribution and cell responses of lymphocyte subsets. Most studies of immunosenescence have been done in populations of industrialized countries living in a rather cold environment, and facing lower antigenic challenges such as Cytomegalovirus (CMV).
