Circassia Pharmaceuticals PLC (CIR.LN) said Tuesday that it will exercise an option to acquire full U.S. commercial rights to Tudorza, a drug for chronic obstructive pulmonary disease.

The pharmaceutical company said it has issued a notice of option exercise to AstraZeneca PLC (AZN.LN), its partner in the development of the drug.

Completion of the option exercise, which is expected on Dec. 31, will trigger a $5 million payment, Circassia said. A deferred payment of $20 million will be payable upon approval of Duaklir--another drug for treatment of chronic obstructive pulmonary disease-- in addition to a deferred consideration of $100 million due under the agreement between AstraZeneca and Circassia.

Circassia shares at 1231 GMT were down 1.8% at 64.80 pence.
