capsules, when used in combination with cytochrome P450 expressing cells, can be placed at the tumor site so that the cells inside the capsule can convert the drug ifosfamide. When the patient is subsequently injected with the chemotherapeutic drug ifosfamide, the encapsulated cells transform this prodrug into its active form, which kills the pancreatic cancer cells.
It is extremely difficult to diagnose pancreatic cancer early on. Approximately 26% of people diagnosed have pancreatic cancer that spreads into the regions beside the tumor and 52% of patients have metastatic disease spread to regional lymph nodes and the liver. From trial and use data, for all pancreatic cancer stages combined there is only a
26% survival rate at 1 year
, whereas using
phase 1/2 clinical trial
the 1-year survival rate was 36%, double that of the standard Gemzar® therapy 1-year results of 18%.
The advantage of this approach is that pancreatic tumors are locally delivered high concentrations of active drug, allowing a decrease to only one-third of the standard amount of ifosfamide, reducing toxic side effects such as nausea, diarrhea, bone marrow suppression and weight loss. Due to the advanced stage most pancreatic cancers are found in, an important question has been whether the reduced amount of drug used can have an effect on the few pancreatic cancer cells, called micro metastases, which leave the primary tumor and are found in organs “downstream” from the original pancreatic tumor.
