This grade answers one narrow question: how strong is the public evidence and safety record behind this drug, and how clean is its money trail and court record? It is not a verdict on whether the drug is right for you.
Listed on the WHO Model List of Essential Medicines: a global expert panel judged it among the medicines a health system should always have, on evidence of value, not marketing.
is a programmed death receptor-1 (PD-1)-blocking antibody indicated for the treatment of: Melanoma • adult and pediatric (12 years and older) patients with unresectable or metastatic melanoma, as a single agent or in combination with ipilimumab. (1.1) • for the adjuvant treatment of adult and pediatric patients 12 years and older with completely resected Stage IIB, Stage IIC, Stage III, or Stage IV melanoma. (1.2) Non-Small Cell Lung Cancer (NSCLC) • adult patients with resectable (tumors ≥4 cm or node positive) non-small cell lung cancer in the neoadjuvant setting, in combination with platinum-doublet chemotherapy. (1.3) • adult patients with resectable (tumors ≥4 cm or node positive) non-small cell lung cancer and no known EGFR mutations or ALK rearrangements, for neoadjuvant treatment, in combination with platinum-doublet chemotherapy, followed by single-agent OPDIVO as adjuvant treatment after surgery. (1.4) • adult patients with metastatic non-small cell lung cancer expressing PD‑L1 (≥1%) as determined by an FDA-authorized test, with no EGFR or ALK genomic tumor aberrations, as first-line treatment in combination with ipilimumab.

Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment. • Withhold or permanently discontinue based on severity and type of reaction. (2.3) • Infusion-related reactions: Interrupt, slow the rate of infusion, or permanently discontinue OPDIVO based on severity of reaction. (5.2) • Complications of allogeneic HSCT: Fatal and other serious complications can occur in patients who receive allogeneic HSCT before or after being treated with a PD-1/PD-L1 blocking antibody. (5.3) • Embryo-Fetal toxicity: Can cause fetal harm. Advise females of reproductive potential of potential risk to a fetus and to use effective contraception. (5.4 , 8.1 , 8.3) • Treatment of patients with multiple myelo...

These are counts of reports people filed, not rates of harm. Anyone can file one, and nobody checks whether the drug was the cause. Millions of doses are taken for every report sent, so the useful part is how this drug compares with the average across all drugs.

Source: the FDA's Adverse Event Reporting System (FAERS). Reports are voluntary and unverified. Drugs that are prescribed a lot, in the news, or in lawsuits attract more reports, so the percentages are compared with the whole database to correct for that partly, not fully.
Counts measure how much evidence exists and how transparent it is, not how big the benefit is. For that, ask your prescriber: if 100 people like me took this, how many would get better because of it, and how many would be harmed? (Doctors call these the "number needed to treat" and "number needed to harm.") It differs by condition and is the number drug ads leave out. Sources: PubMed, ClinicalTrials.gov.
