Frequently asked questions about PF-04995274

What is PF-04995274?

PF-04995274 is an investigational small molecule developed by Pfizer, Inc. It has been studied in Phase 1 clinical trials in healthy adult and elderly volunteers. Its therapeutic indication has not been disclosed, and no Phase 1 trial of PF-04995274 has studied a patient population.

Who makes PF-04995274?

PF-04995274 is developed by Pfizer, Inc., which trades on the New York Stock Exchange under the ticker PFE. Pfizer sponsored all four Phase 1 trials of PF-04995274, which were conducted in the United States and Belgium.

What phase is PF-04995274 in?

PF-04995274 is in Phase 1 clinical development. All four of its recorded trials are Phase 1 studies, and all four are completed, with no active trials ongoing. PF-04995274 is investigational and has not been approved by the FDA for any indication.

What clinical trials is PF-04995274 in?

PF-04995274 has been evaluated in four completed Phase 1 trials: NCT01193062, NCT01173757, NCT01169714, and NCT01091272. These studies enrolled 114 participants in total and examined safety, tolerability, plasma drug levels, cerebrospinal fluid sAPP-alpha changes, and brain receptor binding in healthy volunteers.

What was studied in the PF-04995274 trials?

The PF-04995274 Phase 1 program studied safety, tolerability, and plasma drug concentrations after single and multiple doses in healthy adults and elderly volunteers. One trial measured changes in the cerebrospinal fluid protein sAPP-alpha, and another used PET imaging to evaluate the relationship between plasma drug levels and brain receptor binding.
