简要总结
This study will test the hypothesis that PF-06649751 with continuous co-administration of trimethobenzamide hydrochloride (TMB) with will be safe and well tolerated. Single doses of PF-06649751 will be tested in this study, starting at a low dose and escalating to a dose projected to be under the current limits for drug concentration.

入选标准
- •Healthy male and/or female subjects of non childbearing potential between the ages of 18 and 55 years, inclusive.
- •Body Mass Index (BMI) of 17.5 to 30.5 kg/m2; and a total body weight >50 kg (110 lbs).
- •Evidence of a personally signed and dated informed consent document indicating that the subject has been informed of all pertinent aspects of the study.
排除标准
- •Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at the time of dosing).
- •Treatment with an investigational drug within 30 days (or as determined by the local requirement) or 5 half lives preceding the first dose of study medication (whichever is longer).
- •Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the subject inappropriate for entry into this study.
研究组 & 干预措施
Single Ascending Doses Cohort 1
Single doses, given by oral solution, starting at 0.75 mg up to a possible maximum of 3.0 mg. The subject will have been fasted for 10 hours prior to the single dose. For each dosing period, 3 subjects will be given a placebo as a comparator while 6 are given active dose. The subjects will be given concomitant trimethobenzamide hydrochloride for the 3 weeks that the subject is in the CRU. For each of the three periods, subjects will be crossed-over from placebo or PF-06649751. Each PF-06649751 dose is separated by one week.

Single Ascending Doses Cohort 2
Single doses, given by oral solution, starting at 4.5 mg up to a possible maximum of 9.0 mg. The subject will have been fasted for 10 hours prior to the single dose. For each dosing period, 3 subjects will be given a placebo as a comparator while 6 are given active dose. The subjects will be given concomitant trimethobenzamide hydrochloride for the 3 weeks that the subject is in the CRU. For each of the three periods, subjects will be crossed-over from placebo or PF-06649751. Each PF-06649751 dose is separated by one week.

结局指标
主要结局
Supine and standing vital sign measurements
时间窗: 0 - 4 weeks
Measurement of blood pressure and pulse rate.
Number of Participants With Laboratory Test Values of Potential Clinical Importance
时间窗: 0 - 4 weeks
Pre-defined criteria were established for each laboratory test to define the values that would be identified as of potential clinical importance.
Electrocardiogram (ECG)
时间窗: 0 - 4 weeks
Measurement of standard 12-lead ECG, single or triplicate
Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)
时间窗: 0 - 4 weeks
Counts of participants who have treatment-emergent adverse events (TEAEs), defined as newly occurring or worsening after first dose. Relatedness to PF-06649751 will be assessed by the investigator (Yes/No). Participants with multiple occurrences of an AE within a category will be counted once within the category.
