Exclusion Criteria:

• 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).
• Any condition possibly affecting drug absorption (eg, injuries to subcutaneous tissue at the injection site).
• Any clinically significant, as determined by the investigator, abnormal laboratory evaluations, including HIVAb, HBVsAg, HBVcAb, HCVAb and liver function taken at Screening. The negative HIVAb status will be confirmed at Screening, and all HIV results will be maintained confidentially by the study site.
• History of malignancy, including current malignancy, with the exception of adequately treated squamous or basal cell carcinoma of the skin or cervical carcinoma in situ within 5 years.
• Surgery within the 4 months prior to Screening.
• History of splenic rupture (or participant who is asplenic), pulmonary infiltrate or pneumonia, sickle cell disease, chronic neutropenia, thrombocytopenia, or vasculitis.
• Other medical or psychiatric condition including recent (within the past year) or active suicidal ideation/behavior or laboratory abnormality that may increase the risk of study participation or, in the investigator's judgment, make the participant inappropriate for the study.
• History of biological growth factor exposure, including but not limited to pegfilgrastim, filgrastim and other G-CSFs in the context of treatment, prophylaxis, peripheral blood stem cell mobilization, or previous investigational study setting. This also includes exclusion for history of interferon, epoetin, and IVIG exposure.
• Receipt of live vaccination, or exposure to communicable viral diseases such as chicken pox, varicella, mumps, measles, or COVID-19 within the 4 weeks prior to Screening.
• Use of any prescription medicine (with the exception of contraceptives) within 7 days or at least 5 half-lives, whichever was longer. Use of oral or parenteral anticoagulant or antiplatelet agents and corticosteroids should be specifically queried.
• Administration of a drug by depot injection (with the exception of depot contraception) within 30 days prior to the initial study drug administration or 5 half-lives of that drug, whichever is longer.
• Use of over the counter medications, including aspirin and non-steroidal anti-inflammatory drugs, or natural preparations (dietary supplement or herbal product) within 7 days of the first dose of PF-06881894 or at least 5 half-lives, whichever is longer. Vitamins and calcium supplements are allowed (not to exceed 100% Daily Value). As an exception, acetaminophen/paracetamol may be used at doses of ≤1 g/day. Limited use of non-prescription medications that are not believed to affect participant safety or the overall results of the study may be permitted on a case-by-case basis following approval by the sponsor.
• Females using post-menopausal hormone replacement therapy may be eligible to participate in this study if they are willing to discontinue therapy at least 28 days prior to the first dose of study treatment and remain off hormonal therapy for the duration of the study.

• Screening supine BP >= 140 mm Hg (systolic) or >= 90 mm Hg (diastolic), following at least 5 minutes of rest. If BP is >= 140 mm Hg (systolic) or >= 90 mm Hg (diastolic), the BP should be repeated 2 more times and the average of the 3 BP values should be used to determine the participant's eligibility.
• Screening supine 12-lead ECG demonstrating QTc >450 msec or a QRS interval >120 msec. If QTc exceeds 450 msec, or QRS exceeds 120 msec, the ECG should be repeated two more times and the average of the three QTc or QRS values should be used to determine the participant's eligibility.
• Participants with the following abnormalities in clinical laboratory tests at screening or the Day -5 to Day -4 visit, as assessed by the study specific laboratory will be confirmed by a single repeat test, if deemed necessary. Then the investigator (in consultation with the medical monitor) will determine if the laboratory abnormality is clinically significant and sufficient to exclude the participant from the study.

Lack of adequate hepatic reserve, defined by AST/SGOT or ALT/SGPT >= 1.5 × ULN of the reference laboratory; TBili >= 1.5 × ULN; participants with a history of Gilbert's syndrome may have a direct bilirubin measured and would be eligible for this study provided the direct bilirubin is <= ULN.

Participants with the rare heredity problem of fructose intolerance are excluded due to the excipient sorbitol.
• History of regular alcohol consumption exceeding 7 drinks/week for females or 14 drinks/week for males (1 drink = 5 ounces [150 mL] of wine or 12 ounces [360 mL] of beer or 1.5 ounces [45 mL] of hard liquor) within 6 months of Screening.
• History of sensitivity to heparin or heparin-induced thrombocytopenia.
• Pregnant female participants, breastfeeding female participants, and male participants able to father children and female participants of childbearing potential who are unwilling or unable to use a highly effective method of contraception as outlined in this protocol for the duration of the study and for at least 28 days after the last dose of study intervention.
• Blood donation (including plasma donations) of approximately 1 pint (500 mL) or more within 60 days prior to dosing OR had a transfusion of any blood product within 90 days prior to Screening.
• Unwilling or unable to comply with the criteria in the Lifestyle Considerations section of this protocol. Male participants with pregnant partners are not to be enrolled in the study, even if the participant is willing to comply with the contraception lifestyle requirements and use a highly effective method of contraception consistently and correctly for the duration of the study and for at least 28 days after the last dose of study intervention.
• Investigator site staff or Pfizer employees directly involved in the conduct of the study, site staff otherwise supervised by the investigator, and their respective family members.
