ABSTRACT
Introduction: In the Center for Genetic Engineering and Biotechnology, Havana, Cuba, after carrying out several in vitro studies to interferons, there was obtained a pharmaceutical formulation, named HeberPAG, containing a mixture of human alpha and gamma interferons of synergistic antiproliferative activity, with effect over the growth of some tumor cell lines (epidermoid carcinoma of the larynx, non-small-cell lung cancer, primary cultures of basal cell carcinoma and others). There have been proved other properties such as angiogenesis inhibition, apoptosis stimulation and immune-modulation, which make them widely used in oncologic diseases. It was subjected to preclinical tests which identified it as a safe product to be used in humans and clinical studies where it is proved its intratumoral, perilesional or both applications, with satisfactory results and adverse effects of low intensity. Formulation was optimized and CIGB-128-A was obtained with a higher biological potency than interferons separately.Objective: to study the interferons more deeply.
Methods: bibliographic search was made from September to November, 2016. The 90 % of the selected articles were published in the last five years.
Conclusions: there was achieved with CIGB-128-A an equal or greater response than with HeberPAG in the shortest possible time, which will favor the therapy of cancer patients, susceptible to be treated with this product.
