New drug for platinum resistant ovarian cancer

Multiple new drugs have been developed lung and breast cancers over the last decade.

But only a few new drugs have been approved for ovarian cancers in the past decade.

Drugs like Olaparib and Niraparib – which have been approved for ovarian cancers recently – are maintenance drugs used after chemotherapy rather than used as an upfront treatment .

So it is very good news that a brand new drug is likely to enter the market in the near future.

The new drug is called Relacorilant.(Rela).

It has been tested in ovarian cancers which have become resistant to the platinum drugs.

Platinum drugs are the standard of care ovarian cancers and most other drugs do not work very well once ovarian cancers have become resistant to carboplatin or cisplatin (platinum resistant ovarian cancers).

So it is very good news that we may have a new option now for this group of patients with platinum resistant ovarian cancers.

Early phase drug trial results of Rela in 2023 were promising but not definitive.

Advanced phase 3 trials of Rela have been positive in improving survival (2025).

The study results were due to presented at the prestigious annual meeting of the American Society of Clinical Oncology (ASCO) at Chicago.( June 2025).

More pancreatic cancer patients may benefit from immunotherapy

Immunotherapy has revolutionised cancer treatment over the last few years . But, sadly, not all cancer patients derive benefit from the costly immunotherapy drugs

For instance, almost, all advanced kidney or skin melanoma cancer patients are eligible to try immunotherapy. But only about 1% of patients with pancreatic cancer are at present eligible for immunotherapy .

A new study suggests more people with pancreatic cancer may be eligible for immunotherapy. 

The preliminary data from a good quality early study (randomized phase II trial) is interesting.

The study compared treatment with gemcitabine (G) and nab-paclitaxel (N) with and without dual immunotherapy treatment with durvalumab (D) and tremelimumab (T) as 1st-line therapy in patients with advanced pancreatic cancer. 

In this study, only a subset of patients derived benefit from the dual combination therapy. 

Subsequent molecular and genetic analysis showed that the presence of certain gene mutations (≥2 DDR) was strongly associated with benefit from the combination of chemotherapy with dual immune checkpoint inhibitor therapy. 

These intriguing exploratory data analysis needs confirmatory data before the combination therapy become the standard of care for advanced pancreatic cancer patients.

The study data was presented at the prestigious annual meeting of the American Society of Clinical Oncology (ASCO) hosted at Chicago.
