Brief Summary
BLOOD is an investigator-initiated, multicenter, prospective biomarker study in patients with advanced melanoma treated with anti-PD-1 monotherapy in the first-line setting. The "studied products" will be administered and managed within routine medical care in Belgium. The overall goal is (i) to investigate biomarkers for anti-PD-1 monotherapy and (ii) to gather evidence on real-life use of anti-PD-1 monotherapy in melanoma.

Outcome Measures
Primary Outcomes (2)
The association between ABO blood groups (specifically O vs A/B/AB) and anti-PD-1 monotherapy efficacy.
In terms of objective response rate (ORR) according to RECIST v1.1
25 weeks
Descriptive data on real-life use of anti-PD-1 therapy.
Based on demographics (age, ethnicity, sex, height, weight (and Body Mass Index), smoking status, and gravida/para/abortus (if female)), melanoma history, clinical profile of participant at time of anti-PD-1 initiation, prior and/or concomitant intervention(s), duration of treatment exposure during the study, and effectiveness and safety of anti-PD-1 therapy.
3, 6, 12 months
Secondary Outcomes (15)
The association between ABO blood groups and anti-PD-1 monotherapy efficacy.
12, 25 weeks
The association between ABO blood groups and anti-PD-1 monotherapy efficacy.
3, 6, 12 months
The association between Kell, Kidd, Duffy, MNS, Rhesus, and Dombrock blood group antigens and anti-PD-1 monotherapy efficacy.
12, 25 weeks
The association between Kell, Kidd, Duffy, MNS, Rhesus, and Dombrock blood group antigens and anti-PD-1 monotherapy efficacy.
3, 6, 12 months
The association between irregular antibodies and anti-PD-1 monotherapy efficacy.
12, 25 weeks
- +10 more secondary outcomes
Other Outcomes (3)
The relationship between anti-PD-1 monotherapy efficacy and red blood cell transfusions.
12, 25 weeks and 3, 6, 12 months
The relationship between anti-PD-1 monotherapy efficacy and vaccinations.
12, 25 weeks and 3, 6, 12 months
The relationship between anti-PD-1 monotherapy efficacy and previous pregnancies.
12, 25 weeks and 3, 6, 12 months
Study Arms (1)
Patients with advanced melanoma
Patients receiving anti-PD-1 monotherapy (Nivolumab or Pembrolizumab) in the first-line setting
Interventions
Whole venous blood of participants will be collected in EDTA tubes (max. 10 mL) at baseline, before start of first immunotherapy round. The Belgian Red Cross will perform serological blood group diagnostics, and molecular RBC typing.
Eligibility Criteria
Patients with advanced melanoma
You may qualify if:
- Histologically proven advanced melanoma.
- Anti-PD-1 monotherapy of advanced (unresectable or metastatic) melanoma (prescribed within its approved indication as per usual practice according to RIZIV/INAMI regulations) in the first-line setting.
- No prior systemic therapy for advanced melanoma.
- Have measurable disease per Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1.
- At least 18 years of age.
You may not qualify if:
- Prior treatment with any drug specifically targeting T-cell co-stimulation or immune checkpoints (e.g., antibodies targeting PD-(L)1 or CTLA-4, chimeric antigen receptor T (CAR-T) cell therapy).
- Metastasis-directed therapy (surgery or radiotherapy) with definitive intent (local therapy to address symptomatic sites of disease is permitted).
- Previous systemic treatment for advanced melanoma.
- Active central nervous system (CNS) metastases (previously treated brain metastases are permitted if stable) or carcinomatous meningitis.
