The program priority for execution of this clinical trial changed prior to enrollment of the first patient. The study was not withdrawn due to any safety concerns.

The primary objectives of this study to evaluate the safety, tolerability and efficacy of BGE-117 in the treatment of anemia of aging in participants ≥ 65 years of age.

This is a randomized, placebo-controlled, multicenter, double- blind study of BGE-117 administered PO in participants ≥ 65 years of age for the treatment of anemia of aging. Anemia of aging accounts for approximately one-third of anemia in patients over 65 years of age, defined as a suboptimal hemoglobin level due to different underlying characteristics. This study's planned size is 160 evaluable subjects (80 subjects randomized to BGE-117 and 80 subjects randomized to placebo).

After signing informed consent, participants may be Pre-screened for hemoglobin using HemoCue, and subsequently will be screened for study eligibility. Screening will include full physical examination, vital signs, safety and study-related laboratory evaluation, ophthalmic exam, ECG, Wells score for DVT, and clinical outcome assessment. If confirmed that the participant qualifies for this protocol according to listed inclusion and exclusion criteria, participants will be randomized to BGE-117 or placebo, PO, once per day, for a treatment period duration of approximately 12 weeks. Dose adjustments for study medication during the treatment period are made according to a dosing algorithm to achieve and maintain hemoglobin (Hb) within the target range (12.5-13.0 g/dL). Study procedures and assessments are performed at various timepoints during the treatment period per the schedule outlined in the study protocol. Participants will undergo follow-up assessments for approximately 4 weeks after administration of the last dose.

Inclusion Criteria:

• Ability to voluntarily provide written, signed, and dated informed consent to participate in the study
• An understanding, ability, and willingness to fully comply with study procedures and restrictions
• Is 65 years of age or older at the time of Screening (Visit 1)
• Anemia of Aging defined as a hemoglobin level in the range of ≥ 9.0 g/dL to ≤ 11.5 g/dL (≥ 90 g/L to ≤ 115 g/L) as determined by central laboratory measurement. (Note: For subjects with newly diagnosed anemia, appropriate investigations for the cause of the anemia should be completed according to standard-of-care under the direction of the subject's primary care physician.
• Weight at Screening (Visit 1) is ≥ 40.0 kg

Exclusion Criteria:

• History or diagnosis of any of the following:

  • Anemia due to pernicious anemia, thalassemia, sickle cell anemia, sickle trait, or myelodysplastic syndromes
  • Bone-marrow hypoplasia or pure red cell aplasia
  • Androgen deprivation therapy within the previous12 months or radiation treatment for prostate cancer
  • Thyroid-stimulating hormone (TSH) <0.1 mIU/L or >10.0 mIU/L
  • Folic acid and Vitamin B12 levels less than the lower limit of normal range
  • eGFR as measured by Modification of Diet in Renal Disease (MDRD) <30.0 mL/m/1.73 m2
  • Myocardial infarction, acute coronary syndrome, stroke, transient ischemic attack, or pro thrombotic arrhythmia or condition (e.g., untreated atrial fibrillation) within 6 months before Screening or during the Screening (Visit 1).
  • Cancer diagnosis with active or uncertain disease (i.e. active malignancy), or are receiving active treatment within 12 weeks before Screening (Visit 1) (squamous cell or basal cell carcinoma of the skin are excluded from this criterion)
  • Suspected or history of hematologic malignancy. Remote or childhood hematologic malignancies may be permitted as judged by the investigator. Age-related clonal changes in hematopoiesis (e.g., clonal hematopoiesis of indeterminate potential (CHIP), clonal cytopenia of undetermined significance (CCUS)) are permitted as judged by the investigator.
  • Intravenous (IV) iron within 12 weeks before Screening (Visit 1) or during the Screening Period or Treatment Period. Rescue therapy with IV iron is permitted during the Follow-up Period if the subject's hemoglobin is below their baseline level. Note: oral iron supplementation is permitted. The subject must have started treatment with oral iron supplements at least 4 weeks before Screening. The same dose and dosing regimen should be maintained throughout the Screening Period and Treatment Period.

• Erythropoieisis-stimulating agent (ESA) treatment within 12 weeks before Screening (Visit 1) or during the Screening Period or Treatment Period. Rescue therapy with ESA is permitted during the Follow-up Period if the subject's hemoglobin level is below baseline.

• History of uncontrolled hypertension including:

  • Difficult-to-control hypertension (unless approved by the investigator and the Medical Monitor)

  • Malignant hypertension (unless approved by the investigator and the Medical Monitor)

  • Systolic blood pressure ≥ 160 mmHg or diastolic blood pressure ≥ 95 mmHg (confirmed by repeated measurement) within 2 weeks before randomization. Note:

    • Subjects being treated for hypertension should have been on a stable medication and dosing regimen for at least 8 weeks before randomization
    • Subjects may be rescreened after their blood pressure is controlled

• Evidence of gastrointestinal bleeding within 12 weeks before Screening (Visit 1), as judged by the investigator

• Blood or plasma donation within 8 weeks before Screening (Visit 1) or at any time during the study period.

• Class III heart failure, as defined by the New York Heart Association (NYHA) functional classification system

• QTcF > 500 msec or QTcF > 530 msec in subjects with bundle branch block Note: This evaluation will be done only at Screening (Visit 1); ECG and corresponding intervals and overall interpretation can be mechanically or manually read by an appropriately designated and trained personnel.

• Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≥ 3 × the upper limit of normal (ULN)

• Bilirubin > 1.5 × ULN (isolated bilirubin > 1.5 × ULN is acceptable if bilirubin is fractionated and direct bilirubin is < 35%) Note: Bilirubin increases associated with Gilbert's syndrome are permitted.

• A reported average intake of alcohol of ≥ 80 g/day (i.e., equivalent of 6 cans of beer or 5 shots of hard liquor)

• Increase in hemoglobin level to the target range (12.5-13.0 g/dL) would pose an unacceptable medical risk to the subject, as judged by the investigator

• History of severe allergic or anaphylactic reactions or hypersensitivity to excipients in the investigational product

• Use of another investigational agent within 30 days or 5 half-lives of the investigational agent; whichever is longer

• Prior randomization in the current study (BGE-117-201)

  • Current, unstable active liver or biliary disease (generally defined by the onset of ascites, encephalopathy, coagulopathy, hypoalbuminemia, esophageal/gastric varices, persistent jaundice, or cirrhosis) Note: Stable liver disease (including asymptomatic gallstones, asymptomatic chronic hepatitis B, chronic hepatitis C, or Gilbert's syndrome) is acceptable if the subject otherwise meets entry criteria and the investigator and Sponsor approve entry into the study.
  • Current or relevant history of a medical condition that may require inpatient treatment or make the subject unlikely to complete the study

• Unable or unwilling to adhere to the contraception requirements specified in the protocol
