Brief Summary

This study employs a multicenter, randomized, open-label, positive drug-controlled, multiple ascending dose clinical trial design to comprehensively evaluate the safety, tolerability, immunogenicity, and pharmacokinetic characteristics of SSS06 injection in patients with chemotherapy-induced anemia from non-myeloid malignancies, while also exploring its potential efficacy.

Conditions

Chemotherapy-induced Anemia; Non-myeloid Malignancies

Outcome Measures

rhEPO DRUG

a recombinant human erythropoietin injection.

Also known as: Yibiao

Positive control group

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Male or female participants aged ≥18 years at the time of signing the informed consent.
• Histologically or cytologically confirmed diagnosis of non-myeloid malignancies.
• Chemotherapy-induced anemia defined as hemoglobin (Hb) ≤100 g/L at screening, with a documented decrease in Hb of ≥10 g/L post chemotherapy initiation, as judged by the investigator.
• Serum ferritin ≥50 ng/mL and transferrin saturation (TSAT) ≥10% at screening.
• Body weight ≥40 kg at screening.
• Eastern Cooperative Oncology Group (ECOG) performance status score of 1 or 2 at screening.
• Expected survival ≥6 months.
• Planned to receive at least 8 weeks of myelosuppressive chemotherapy starting from Day 1 of the study.
• Childbearing women must agree to use reliable contraception and have no plans to conceive or donate eggs from the start of study drug administration until 6 months post-last dose. Men must agree to use reliable contraception and have no plans to father a child or donate sperm from the start of study drug administration until 6 months post-last dose.
• Voluntarily sign informed consent, willing to participate in the trial, and able to comply with the protocol requirements for administration and follow-up, including examinations, visits, and other procedures.

You may not qualify if:

• Patients undergoing myelosuppressive chemotherapy with an expected curative outcome.
• Subjects receiving only hormone therapy, biologics, immunosuppressants (e.g., PD-1 and PD-L1 immune checkpoint inhibitors), or targeted therapies, or radiation therapy to treat/control their tumors; however, subjects receiving chemotherapy in combination with these therapies may be included.
• Subjects with a hematocrit (HCT) ≥ 36%.
• Subjects who have undergone interventions (e.g., blood transfusion, erythropoiesis-stimulating agents (ESAs), or hypoxia-inducible factor prolyl hydroxylase inhibitors (HIF-PHIs)) to elevate hemoglobin (Hb) levels to meet chemotherapy safety standards prior to the initiation of the scheduled chemotherapy regimen.
• Subjects who received red blood cell (RBC) transfusions, ESAs, or HIF-PHIs within 4 weeks prior to enrollment.
• Subjects with abnormal liver or kidney function test results: alanine aminotransferase (ALT) \> 3×ULN, aspartate aminotransferase (AST) \> 3×ULN, or total bilirubin (TBL) \> 1.5×ULN (subjects with TBL up to 2×ULN may be included if ALT/AST are within normal limits and the investigator deems no safety concerns). Estimated glomerular filtration rate (eGFR) \< 30 mL/min/1.73 m² (calculated using the CKD-EPI formula).
• Subjects with active systemic infections requiring treatment.
• Subjects with a history of clinically significant cardiovascular disease, including New York Heart Association (NYHA) Class III or IV heart failure within the past 6 months, uncontrolled hypertension or hypotension, or severe valvular or endocardial disease history that may increase the risk of thromboembolic events.
• Subjects who experienced thromboembolic events (e.g., deep vein thrombosis, pulmonary embolism, myocardial infarction, stroke, transient ischemic attack) within the past 6 months.
• Subjects with clinically significant anemia due to other causes, such as iron deficiency, vitamin B12 or folate deficiency, autoimmune anemia, hemolysis, hemorrhage, or genetic anemias (e.g., sickle cell anemia or thalassemia).
• Subjects with clinically significant or uncontrolled chronic inflammatory or autoimmune diseases (e.g., rheumatoid arthritis, Crohn's disease, celiac disease).
• Subjects with severe or active liver disease.
• Subjects planning to undergo major surgery during the treatment period (surgery with minimal blood loss that does not affect Hb concentration is exempt).
• Subjects with myeloid malignancies.
• Subjects with primary or metastatic malignant tumors in the central nervous system.
