According to reports, AstraZeneca's experimental anti-PD-L1 immunotherapy drug MEDI4736 will be tested alongside Lilly's approved medicine Cyramza, or ramucirumab. The early-stage Phase I trial will be run by Lilly.
Cramer said Astra Zeneca has a number of other promising drugs in the pipeline that could prove effective in the fight against cancer, making additional partnerships possible.
The potential of drugs that unleash the body's immune system to fight cancer will be the main focus of the annual meeting of the American Society of Clinical Oncology starting later Friday in Chicago.
"This is a brilliant move by Lilly," said Cramer, portfolio manager for Action Alerts PLUS. "It's a fabulous tie-up, Just fabulous."
