Aim: To overcome the limitations associated with conventional formulations for cancer treatment by the effective utilization of nanoemulsion with therapy and diagnosis through the single unit. Patent: US20210275687 describes the usage of functionalized various oil-in-water nanoemulsions as pharmacological vehicles with theranostic potential in cancer treatment. Materials & methods: Vitamin E, oleic acid, sphingomyelin, ligands for functionalization, contrast agents and therapeutic biomolecules. Results: The toxicity studies conducted on healthy mice did not show any apparent toxicity issues. The stability studies conducted at 40 °C and 75% relative humidity, which is mandatory for regulatory approval, indicated the adequate physical stability of the formulation. Conclusion: The studies exhibited the promising theranostic potential of the developed nanoemulsion for the effective management and diagnosis of cancer and metastatic diseases.

Co-crystallization is a technique for modifying physicochemical properties of pharmaceutical ingredients with an aim to enhance the therapeutic efficacy and subsequent reduction in toxicity. The patent describes the development of oxaliplatin co-crystals using flavonoids (baicalein and naringenin) via solvent volatilization technique with an objective to improve solubility and stability in GI tract and reduced side/toxic effects. The co-crystals were characterized via differential scanning calorimetry, thermogravimetric analysis, x-ray diffraction analysis. The co-crystals exhibited slow drug release, delayed hydrolysis, low cytotoxicity and enhanced therapeutic activity on human gastric adenocarcinoma cells. However, suitable solvent for co-crystal production, large scale production and regulatory challenges for continuous manufacturing of co-crystals must be addressed.

A challenge in anticipating generic entry is elucidating which patents and regulatory protections constrain generic entry. Presented here is a set of estimated loss of exclusivity dates for six drugs, from May through June 2022. These estimated drug patent expiration dates and generic entry opportunity dates are calculated from analysis of known patents and US regulatory protections covering drugs [1]. This methodology can be extended to ex-US jurisdictions by leveraging these estimates and tracking patent family members in other patent offices.

By December 2021, the COVID-19 caused approximately 6.1 million deaths around the world. Several vaccines have been approved, but there is still a need for non-prophylactic treatments for COVID-19. Remdesivir is an antiviral drug approved for emergency use against COVID-19 in several countries, but one of the first clinical trials was inconclusive about the mortality reduction, although the drug showed a reduction in the recovery time of hospitalized patients. Thus, the present investigation revisits the clinical evidence of using remdesivir for COVID-19 treatment, patent status, pharmacology and chemistry. We found 184 families of patents in the Cortellis database, and concerning the clinical evidence, we retrieved 14 systematic reviews with meta-analysis involving remdesivir as a treatment for COVID-19, discussing the reduction of adverse events, hospitalization days, mortality rate and the mechanical ventilation period.
