  • Gender: Male or Female

Inclusion Criteria:

  1. Age 18 or older
  2. Adequate renal, hematological, hepatic function defined as:
    • Normal renal function defined as serum creatinine 1.5 mg/dl or creatinine clearance
    • 60 mL/min/1.73 m2 (according to local evaluation method).
    • Hepatic function: alkaline phosphatase 2.5 LSN, aspartate aminotransferase (AST) 2.5 LSN, alanine aminotransferase 2.5 LSN, total bilirubin 1.5 LSN.
    • Leukocyte count 3,000/mcL, neutrophils absolute count 1500/mm3 (1.5 109/L).

Platelets 100,000/mm3 (100 109/L) and Hemoglobin 9.0 g/dL in peripheral blood.

  • Cardiovascular function: No evidence of acute ischemic heart disease in the electrocardiogram. 3. No uncontrolled or significant comorbidities determined by clinical history, physical examination and screening laboratory tests at the discretion of the investigator. 4. Women of childbearing age must have a negative pregnancy test (urine or serum) at the time of screening and enrollment. 5. Female subjects of childbearing age (those who have not been menopausal at least for 12 months or who have undergone surgical sterilization by bilateral tubal ligation procedure, bilateral oophorectomy or hysterectomy), and their male partners, must use at least one of the below mentioned contraceptive methods at the time of entering the study, throughout the study, and at least 6 months following the P3Et use (the effects of

P2Et in the developing human fetus are unknown):

  1. Total abstinence of sexual intercourse, starting at least one complete menstrual cycle prior to the administration of the study drug; (it should be noted that: sexual abstinence as a contraceptive method must be limited to those cases in which it has been established as the pre-existent election of lifestyle by the patient);

  3. Hormonal contraceptives (oral, parenteral or transdermal) for at least 3 months prior to the administration of the study drug;
  4. Intrauterine device (IUD)

  7. The subject must sign and date the informed consent form voluntarily for his (her) participation in the study, approved by an Institutional Ethics Committee (IEC) prior to the initiation of any selection procedure or specific to the study.

Exclusion Criteria:

  2. History of allergic reactions attributed to polyphenol-type compounds similar to those found in green tea.
  3. Use of dietary supplements or phytopharmaceutical drugs < 15 days prior to the admission and during the study.
  4. Subjects with diagnosis of an active disease and/or receiving pharmacological treatment prescribed for an active disease and who have evidence of an active disease at the time of the initial clinical examination at the discretion of the investigator.
  5. Severe, active concomitant morbidity, including but not limited to:
    • Bacterial or fungal acute infection requiring intravenous antibiotics at the time of inclusion.
    • Moderate or severe liver failure (B or higher Child-Pugh category with qualification 7 or higher).

    • Exacerbation of chronic obstructive pulmonary disease or another respiratory disease requiring hospitalization or that precludes the study treatment at the time of inclusion.
    • Subjects with a disease indicative of clinically defined Acquired Immunodeficiency Syndrome (AIDS). This is necessary in order to assure that those subjects can be more likely to be suitable to receive the full treatment.
    • Any other major clinical disease or psychiatric disorder that, at the discretion of the investigator, precludes the administration or completion of the protocol treatment.
  6. Voluntary subjects having history or drugs and/or alcohol abuse.
