UPDATE 2-Key AstraZeneca drug shown to reduce risk of death from lung cancer

* Positive trial results put AstraZeneca ahead of rivals

LONDON, May 12 (Reuters) - A trial of AstraZeneca’s key immunotherapy drug durvalumab showed it reduced the risk of death from advanced lung cancer, giving it a lead over rivals as it seeks to transform its oncology business.

The trial results are an unexpectedly early boost for the product, known commercially as Imfinzi, which the company hopes will become a blockbuster drug with sales in the billions of dollars.

Shares in AstraZeneca were up 4.7 percent by 1000 GMT, the top FTSE 100 riser, and the company said it was in talks with the authorities over plans for regulatory approval.

“These are highly encouraging results for patients with locally-advanced lung cancer for whom surgery is not an option,” Sean Bohen, Executive Vice President, Global Medicines Development at AstraZeneca, said in a statement.

Analysts said the results of the trial, known as PACIFIC, showed AstraZeneca was ahead of competitors as there was a gap in the market for such treatment. It also augured well for another trial due in mid-2017 which could mean the drug could be used in combination in newly diagnosed cases.

“The surprise early positive readout of the PACIFIC trial of... durvalumab (Imfinzi) in locally advanced lung cancer is a major inflection point for AstraZeneca’s immuno-oncology,” analysts at Deutsche Bank said in a note.

“In theory, this could open a market opportunity of $1.75bn to $3.5bn (or more) for the drug, which is not included in our current forecasts.”

AstraZeneca is looking to sales of recently launched and experimental cancer medicines to help offset the impact of a loss of patents on blockbusters such as cholesterol pill Crestor.

The drug works by helping the body’s immune cells kill cancer, offering an alternative to chemotherapy.

The trial found that durvalumab “significantly reduces risk of disease worsening or death” in forms of lung cancer which are difficult to operate on but have not spread. In this trial it was used after chemotherapy or radiation therapy.

Analysts at Berenberg said that trial results, which were earlier than expected, put AstraZeneca ahead of rivals Roche and Merck, whose trials for similar treatments aren’t expected until September 2019.

They also said the efficacy of durvalumab in PACIFIC augured well for the results of a trial of the drug in a combination therapy, called MYSTIC. That is used used on more advanced cancers, but before or instead of chemotherapy, and results are expected in June or July.

“While MYSTIC is still very important, PACIFIC clearly lessens its importance, and provides more reassurance that Imfinzi is an active drug and therefore must have a chance of working in MYSTIC,” analysts at Berenberg said.

U.S. regulators earlier this month approved durvalumab as a treatment for bladder cancer, marking the first commercial green light for the product. (Reporting by Alistair Smout; Editing by Keith Weir)
