Frequently asked questions about PH-797804

What is PH-797804 used for?

PH-797804 is an investigational small molecule being developed by Pfizer for the treatment of chronic obstructive pulmonary disease (COPD). It has been studied in a Phase 2 trial in adults with moderate to severe COPD, and it is also being evaluated in healthy volunteer studies. The drug is not approved and remains in clinical development.

What does PH-797804 target?

PH-797804 is a small molecule that targets p38 MAP kinase, an enzyme involved in inflammatory signaling. By inhibiting this target, the drug is intended to reduce inflammation in conditions like COPD. This mechanism was studied in a Phase 2 trial for COPD and in healthy volunteer studies.

Who makes PH-797804?

PH-797804 is developed by Pfizer, Inc., a biopharmaceutical company listed on the New York Stock Exchange under the ticker PFE. Pfizer has conducted clinical trials of PH-797804 in multiple countries, including the United States, for the treatment of chronic obstructive pulmonary disease.

What phase is PH-797804 in?

PH-797804 has completed Phase 2 clinical development for chronic obstructive pulmonary disease. It has also completed Phase 1 studies in healthy volunteers. The drug is investigational and has not received FDA approval. All three clinical trials for PH-797804 have been completed, with no active trials currently ongoing.

What clinical trials has PH-797804 been in?

PH-797804 has been studied in three completed clinical trials. The Phase 2 trial NCT01543919 evaluated its efficacy and safety in 730 adults with moderate to severe COPD. Phase 1 trials include NCT01589614, which studied its interaction with erythromycin in 12 healthy subjects, and NCT01862887, which assessed its effect on QTc interval in 48 healthy volunteers.

Is PH-797804 the same as other drugs?

PH-797804 is a distinct investigational compound developed by Pfizer. It is not known to be the same as any other marketed drug. Its development has focused on chronic obstructive pulmonary disease, and it has been studied in clinical trials under its own name, PH-797804.
