Licensing Manager at Benemérita Universidad Autónoma de Puebla
In addition to my research interest, I am the head of the innovation and business area of the Benemerita Universidad Autonoma de Puebla. This area is responsible for the registration and licensing of patents at the university, as well as the creation of technology companies.
My research interest is in the area of immunotherapy, particularly in agonist or antagonist antibodies directed against checkpoint molecules in cancer, such as PD-1, PD-L1, CTLA-4, LAG3 and OX40.

Introduction: LAG-3 is checkpoint inhibitor in cancer that coordinates the downregulation of the proliferation of antigen-specific lymphocytes. There is a great need to discover and develop new therapies focused on inhibiting the action of LAG-3 and consequently improving the immune response in the various types of cancer. Areas covered: The patent literature reveals novel therapies, which provide information on cancer therapies. The authors used the patent databases of the six main patent offices of the world: United States Patent and Trademark Office, European Patent Office, World Intellectual Property Organization, Japan Patent Office, State Intellectual Property Office of China and Korean Intellectual Property Office, to generate a detailed landscape of patents and patent applications of active companies related to LAG-3 inhibitors. Specific patents have been grouped into innovative patents and adopting patents. Expert opinion: There is a continuing development of LAG-3 inhibitors, and these inhibitors are being used in combination with other cancer treatment schemes, for example, antibodies against PD-1, PD-L1, and CTLA-4. Immutep and IO Therapeutics were the leaders in generating innovator patents, followed by Gustave Roussy Institute, and Applied Research Systems ARS. Dana-Farber Cancer Institute was the leader in the generation of adopter patents, followed by Novartis .

Introduction: Due to the primary role of PD-1 and LAG-3 in regulating the immune response in tumors, there is a need to develop therapies focused on the inhibition of PD-1 and LAG-3 in order to improve the immune response in patients with cancer. The authors of US2018326054 patent propose a method to eradicate cancer by using bispecific anti-PD-1/LAG-3 antibodies.Areas covered: The US2018326054 patent describes anti-PD-1/LAG3 antibodies, pharmaceutical composition that contains it, and their application for cancer treatment, particularly pancreatic carcinoma. Proof concept and preclinical results show anti-PD-1/LAG-3 bispecific antibodies bind and are internalized by CD4 + T cells thereby increasing their effector functions (release of Granzyme B and INF-γ) in the presence of tumor cells, and completely suppress tumors in a murine model.Expert opinion: Anti-PD-1/LAG-3 bispecific antibodies of the US2018326054 patent are new in a general concept, but treatment data is only shown for pancreatic carcinoma. The results to be obtained in future clinical trials of safety and efficacy could conclude whether these bispecific anti-PD-1/LAG-3 antibodies will be useful in a cancer treatment scheme.

LAG-3 is checkpoint inhibitor in cancer that coordinates the down regulation of the proliferation of antigen-specific lymphocytes. There is a great need to discover and develop new therapies focused on inhibiting the action of LAG-3 and consequently improving the immune response in the various types of cancer. Authors of patent US2018271940 propose a method to eradicate cancer that utilizes the combination of LAG-3Ig and anti-PD-1 or anti-PD-L1 antibodies. Areas covered: Patent US2018271940 describes a method consisting of the utilization of either a pharmaceutical cocktail containing LAG-3Ig and an anti-PD-1 or anti-PD-L1 antibody for activation of T cells as a potential for the treatment of cancer. Expert opinion: Data supporting the patent demonstrate the ability of LAG-3Ig and PD-1/PD-L1 to be useful in T cells activation, in addition to the reports showing that LAG-3 and anti-PD-1 and PD-L1 antibodies are therapeutic agents against cancer. Although the proposed methodology is very interesting and promising, further studies are necessary to assess the clinical applicability of the inventions on cancer.

Introduction: OX40 is a potent costimulatory receptor of the immune response in various types of cancer and has been used as a target for the generation of agonists of its function. Authors of WO2018202649 patent propose a method to eradicate cancer using a bispecific antibodies against OX40/CTLA-4.Areas covered: WO2018202649 patent describes several bispecific antibodies capable of specifically binding to OX40 and CTLA-4 that target regulatory T cells in the tumor microenvironment.Expert opinion: WO2018202649 patent demonstrates that bispecific antibodies against OX40/CTLA-4 have anti-tumor activity against colon, pancreatic and bladder cancer, and that there is a synergistic action with anti-PD-1 antibodies for the treatment of colon cancer. However, there is no evidence to conclude that bispecific antibodies can be used in cancers other than colon, pancreas and bladder. Likewise, the patent only describes the application in combinatorial therapy with anti-PD-1 antibodies, without presenting data relative to the combination with other immunotherapeutic agents against other checkpoint targets.

Introduction: OX40 is checkpoint inhibitor in cancer that coordinates the downregulation of the proliferation of antigen-specific lymphocytes. There is a great need to discover and develop new therapies focused on inhibiting the action of OX40 and consequently improving the immune response in the various types of cancer. Authors of patent US2018256711A1 propose a method to eradicate cancer that utilizes anti-OX40 agonist antibody in combination with anti-PD-L1 antagonist antibody. Areas covered: Patent US2018256711A1 describes a method of cancer combinatorial treatment consisting of the utilization of a pharmaceutical cocktail containing anti-OX40 and an anti-PD-L1 antibody. Expert opinion: The results of the clinical trials only support trials regarding the tolerability of combinatorial therapy, even when the objectives of determining the safety and pharmacokinetics of the treatment are proposed.
