ABSTRACT
Introduction
Nanotechnology may open up new avenues for overcoming the challenges of pancreatic cancer therapy as a broad arsenal of anticancer medicines fail to realize their full therapeutic potential in pancreatic ductal adenocarcinoma due to the formation of multiple resistance mechanisms inside the tumor. Many studies have reported the successful use of various nano formulations in pancreatic cancer therapy.
Areas covered
This review covers all the major nanotechnology-based patent litrature available on renowned patent data bases like Patentscope and Espacenet, through the time period of 2007–2022. This is an entirely patent centric review, and it includes both clinical and non-clinical data available on nanotechnology-based therapeutics and diagnostic tools for pancreatic cancer.
Expert opinion
For the sake of understanding, the patents are categorized under various formulation-specific heads like metallic/non-metallic nanoparticles, polymeric nanoparticles, liposomes, carbon nanotubes, protein nanoparticles and liposomes. This distinguishes one specific nanoparticle type from another and makes this review a one-of-a-kind comprehensive patent compilation that has not been reported so far in the history of nanotechnological formulations in pancreatic cancer.
Article highlights
Pancreatic cancer is one of the leading causes of cancer related deaths and morbidities worldwide. It is the need of the hour to develop new therapeutic stratagems for treating this deadly and evasive form of cancer.
The most challenging aspect in therapy of pancreatic cancer is that it is resistant to most of the newest treatment approaches therapeutic combinations.
Patients inflicted with this deadly form of cancer have a very few treatment options at hand and reformative research is needed as we don’t have any major patents in this arena so far.
Nanotechnology may open up new avenues for overcoming the challenges of pancreatic cancer therapy.
We outline major patents that harness the unique tumor targeting capabilities of nanomedicine from 2007 to 2022.
Connective research is needed further in order to establish the veracity and effectiveness of the claims made in the patents discussed.
