The purpose of this study is to investigate the pharmacokinetics (PK) similarity of Bmab1700 (an intended nivolumab biosimilar), compared with United States (US)-licensed Opdivo, in participants after complete surgical removal of melanoma.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion criteria
. Participants greater than or equal to (\>=)18 years of age on the day of signing informed consent (follow local regulatory requirements if the legal age of consent for study participation is \>18 years old).
. Able to understand and willing to provide consent using the study Informed Consent Form (ICF). The voluntarily signed ICF must be obtained before any study-specific procedures are performed.
. Histologically or cytologically confirmed Stage IIB, Stage IIC, Stage III, or Stage IV melanoma (per American Joint Committee on Cancer, 8th edition) that was completely surgically resected. Complete surgical resection requires removal of all clinically or radiographically evident regional disease. Completion of lymph node dissection is not required unless clinically indicated. Participants must have been surgically rendered free of disease with negative margins on resected specimens documented by appropriate pathology and surgical reports.
. Complete surgical resection of melanoma must have been performed within 12 weeks before randomization.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Area Under the Concentration-Time Curve from Time 0 (Day 1) To Day 29 After the First Dose (AUC0-28days) of Bmab 1700 and Opdivo
Timeframe: Week 0 through Week 4
2
Area Under the Concentration-Time Curve Over a Dosing Interval (AUC0-tau) of Bmab 1700 and Opdivo
. All participants must have disease-free status documented by a complete physical examination and imaging studies before randomization.
. Eastern Cooperative Oncology Group (ECOG) performance status score of 0 or 1.
. Participants must have recovered from melanoma related surgery and its complications before randomization, as per investigator.
Exclusion criteria
. History of ocular/uveal melanoma.
. Participants with an active, known, or suspected autoimmune disease are to be excluded from participation. Participants who have received systemic treatment for an autoimmune disease within the past 2 years before randomization (eg, with disease-modifying agents, corticosteroids, or immunosuppressive drugs) are also excluded.
. History of active malignancy other than melanoma under study within 3 years before randomization, except for locally curable early-stage cancers (carcinoma in situ or Stage I) that have been curatively treated, such as basal or squamous cell skin cancer, superficial bladder cancer, or carcinoma in situ of the prostate, cervix, or breast.
. Participants with a condition requiring systemic treatment with either corticosteroids \>10 mg daily prednisone or equivalent or other immunosuppressive medications within 14 days before randomization. Inhaled or topical steroids, and adrenal replacement steroid doses \<=10 mg daily prednisone or equivalent, are permitted in the absence of active autoimmune disease
. Female participants who are pregnant or breastfeeding at the screening visit, or who intend to become pregnant or breastfeed at any time during the study and for 150 days after the last dose of study intervention.
. Use of an investigational agent or an investigational device within 28 days or 5 half-lives (if half-life is known for the investigational agent), whichever is longer, before randomization or have not recovered from AEs associated with such therapies to Grade 1 or below (based on CTCAE Version 6.0).
. Any antineoplastic therapy after the complete resection of melanoma under study (eg, chemotherapy, radiation therapy, targeted agents, biotherapy, or limb perfusion).
. Participants who have received a live/attenuated vaccine within 28 days before randomization. Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster (chicken pox), yellow fever, rabies, Bacillus Calmette-Guérin, and typhoid vaccine.
