Two drugs in combination improve survival in patients with advanced pancreatic cancer

In continuation of my update on nab-paclitaxel (stands for nab-nanoparticle albumin-bound) and gemcitabine...

Investigators at the Vall d´Hebron University Hospital and the Vall d'Hebron Institute of Oncology (VHIO), have participated in an international phase III study, published in The New England Journal of Medicine. Results show that administering these two drugs in combination significantly improves one- and two-year survival in patients with advanced pancreatic cancer versus gemcitabine alone, the first-line treatment or most standard approach for this type of cancer to date.
The new drug is set to become a reference in advanced pancreatic cancer treatment. A multicentre phase III study, with centers participating from 11 countries in North America, Europe and Australia, shows that the drug combination nab-paclitaxel and gemcitabine is more effective in the treatment of patients with advanced pancreatic cancer than gemcitabine alone, which has been the standard treatment for these patients up until now.

The clinical trial, sponsored by Celgene Corporation, involved 861 patients, half of whom were administered the nab-paclitaxel/gemcitabine combination, while the other half received gemcitabine alone. Median overall survival was 8.5 months for nab-paclitaxel/gemcitabine versus 6.7 months for gemcitabine alone. One-year survival rates were 35% and 22%, respectively, and two-year survival rates were 9% and 4%, respectively. Similar side effects were found in the new drug and gemcitabine alike. The trial report therefore concluded that the nab-paclitaxel/gemcitabine combination significantly improves overall survival and response rate in patients with advanced pancreatic cancer.

Drug combination extends pancreatic cancer patient survival, study suggests

A multi-center Phase III clinical trial demonstrates that Abraxane (below left structure) (nab-paclitaxel) plus gemcitabine is the first combination of cancer drugs to extend survival of late-stage pancreatic cancer patients compared to standard treatment. Their findings show that Abraxane plus gemcitabine (below right structure) was well tolerated and resulted in clinically meaningful outcomes compared to gemcitabine alone, the current standard of care. 


MPACT is the largest phase III clinical trial completed in advanced pancreatic cancer with more than 800 patients. Findings from the study showed a 59 percent increase in one-year median survival rates from less than a quarter of the patients (22 percent) to more than a third (35 percent). The two-year survival rate for this cancer is negligible, less than 4 percent, but that more than doubles (9 percent) with the nab-paclitaxel/gemcitabine combination.

The study showed significant improvement among some of the sickest patients including those with increased metastases. Significantly there was no increase in life-threatening toxicity. Other drug combinations that have demonstrated benefit have been limited by increased toxicities.

"This is a major improvement in a cancer with the lowest survival rates among all cancer types," said Dr. Ramesh Ramanathan, medical director of Virginia G. Piper Cancer Center Clinical Trials at Scottsdale Healthcare and principal investigator for the clinical trial in the United States. "Advanced pancreatic cancer is fourth most common cause of cancer death in the United States and throughout the world. It is difficult to diagnose with a majority of the cases diagnosed at a late stage after the disease has already advanced."
