Few cancer drugs carry as many separate approvals as the one this article covers. It is a PD-1 inhibitor — a type of immunotherapy — approved across eleven different cancer types, from lung cancer to mesothelioma, sometimes alone and sometimes paired with another immunotherapy, chemotherapy, or a targeted drug.
Because the approved combinations and dosing vary so much by cancer type, this guide focuses on how the treatment works in general, which cancers it covers, what the FDA-reviewed trial data actually showed for each one, and what to expect around side effects and access. Every figure below is drawn directly from the current FDA-approved prescribing information, not from journal articles or secondhand summaries. Approvals and label wording change over time and differ by country, so this is background reading — not a replacement for what your own oncologist tells you.
| Drug class | PD-1 (programmed death receptor-1) blocking antibody — a checkpoint inhibitor immunotherapy, not chemotherapy |
| Brand name | Opdivo (nivolumab), Bristol Myers Squibb |
| How it is given | Intravenous (IV) infusion, alone or combined with another immunotherapy, chemotherapy, or a targeted drug, depending on the cancer |
| Cancers covered | Eleven types — see the table below |
| Typical dose | 240 mg every 2 weeks, 360 mg every 3 weeks, or 480 mg every 4 weeks as a fixed dose — the exact regimen and combination partner depend on the specific cancer and treatment line |
| Before starting | Not every use needs a biomarker test, but several do (for example, PD-L1 or MSI-H/dMMR testing) — ask which applies to your case |
| Main safety concern | Immune-mediated side effects — the immune system can be switched on against healthy organs, not just the tumor |
| Good to know | Not a cure in most settings; it is used to extend the time a cancer stays controlled, and in a few settings, to reduce the risk of recurrence after surgery |
T-cells are the immune system's cancer-fighting cells. Many tumors protect themselves by activating a checkpoint protein called PD-1 on T-cells, which effectively switches those T-cells off before they can attack.
PD-1 A checkpoint receptor on T-cells that, once triggered, tells the immune system to stand down. | PD-L1 A protein many tumors display to trigger that PD-1 checkpoint and hide from the immune system. | What this drug does Blocks PD-1 so the checkpoint cannot be triggered. T-cells stay active and can recognize and attack the tumor. |
This is why it is called a checkpoint inhibitor: it does not attack cancer cells directly the way chemotherapy does. It releases a brake the immune system already had, which is also why the main safety risk is an immune system that becomes overactive against normal tissue, not the classic chemotherapy side effects like hair loss.
More checkpoints blocked at once generally means a stronger response and a higher chance of an immune-related side effect — which is why the FDA has approved this combination for some cancers and risk groups, and not others.
The table gives the current FDA-approved picture. Several cancers have more than one approved use (for example, both a first-line combination and a later-line single-agent option) — the sections after the table go into more detail for each.
| Cancer | Typical setting | Usually combined with |
|---|---|---|
| Non-small cell lung cancer (NSCLC) | Resectable disease before/after surgery, or metastatic disease, first-line or after chemotherapy | Chemotherapy, ipilimumab, or given alone |
| Melanoma | Unresectable/metastatic disease, or after surgery to reduce recurrence risk | Alone or with ipilimumab |
| Renal cell carcinoma (RCC) | First-line advanced disease, or after prior anti-angiogenic therapy | Ipilimumab, cabozantinib, or given alone |
| Classical Hodgkin lymphoma | Previously untreated Stage III/IV, or relapsed after stem cell transplant | AVD chemotherapy, or given alone |
| Head and neck squamous cell carcinoma | Recurrent or metastatic, after platinum-based therapy | Given alone |
| Urothelial carcinoma | After surgery (high recurrence risk), first-line metastatic, or after chemotherapy | Cisplatin and gemcitabine, or given alone |
| Colorectal cancer (MSI-H/dMMR) | Unresectable or metastatic, any treatment line | Ipilimumab, or given alone |
| Hepatocellular carcinoma (HCC) | Unresectable or metastatic, first-line or after sorafenib | Ipilimumab |
| Esophageal cancer | After surgery with residual disease, or advanced squamous cell disease | Chemotherapy, ipilimumab, or given alone |
| Gastric, gastroesophageal junction and esophageal adenocarcinoma | Advanced or metastatic, PD-L1 expressing | Chemotherapy |
| Malignant pleural mesothelioma | Unresectable, first-line | Ipilimumab |
This is the largest of the eleven approvals, covering everything from early, operable disease to advanced disease that has already progressed on chemotherapy.
| 17.1 vs 14.9 months | CheckMate-227 · NCT02477826 Median overall survival, first-line combined with ipilimumab vs chemotherapy, in patients with PD-L1≥1% tumors (hazard ratio 0.79). |
| 12.2 vs 9.4 months | CheckMate-057 · NCT01673867 Median overall survival, single agent vs chemotherapy, in previously treated non-squamous NSCLC (hazard ratio 0.73). |
Melanoma is where this class of drug first transformed outcomes for advanced disease, and it remains one of its best-studied uses.
| NR vs 36.9 vs 19.9 mo | CheckMate-067 · NCT01844505 Median overall survival with combination therapy (not reached), single-agent therapy (36.9 months), and ipilimumab alone (19.9 months), based on extended follow-up (hazard ratio 0.55 for combination vs ipilimumab alone). The trial was not designed to prove the combination beats single-agent treatment directly. |
| NR vs 25.9 months | CheckMate-214 · NCT02231749 Median overall survival, combined with ipilimumab vs sunitinib, in intermediate/poor-risk patients (hazard ratio 0.63). |
| 37.7 vs 34.3 months | CheckMate-9ER · NCT03141177 Updated median overall survival, combined with cabozantinib vs sunitinib (hazard ratio 0.70). |
| HR 0.42 | SWOG S1826 · NCT03907488 Progression-free survival, combined with AVD vs brentuximab vedotin plus AVD, in previously untreated Stage III/IV disease. Events occurred in 5.6% vs 12.4% of patients over the follow-up period studied. |
| 66–69% response rate | Pooled relapsed/refractory data Confirmed overall response rate as a single agent in patients who had relapsed after stem cell transplant, across two supporting trials (CheckMate-205 and CheckMate-039). |
Approved as a single agent for disease that has come back or spread after platinum-based chemotherapy.
| 7.5 vs 5.1 months | CheckMate-141 · NCT02105636 Median overall survival vs investigator-selected of chemotherapy (cetuximab, methotrexate or docetaxel), hazard ratio 0.70. |
| 21.7 vs 18.9 months | CheckMate-901 · NCT03036098 Median overall survival, first-line combined with cisplatin and gemcitabine vs chemotherapy alone (hazard ratio 0.78). |
| 20.8 vs 10.8 months | CheckMate-274 · NCT02632409 Median disease-free survival as adjuvant treatment after surgery, vs placebo (hazard ratio 0.70). |
This approval applies only to a specific biomarker subset — tumors that are microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR), meaning they have lost the ability to correctly repair certain DNA errors. This is a minority of colorectal cancers overall, but one where checkpoint inhibitors work unusually well.
| NR vs 5.8 months | CheckMate-8HW · NCT03143153 Median progression-free survival, first-line combined with ipilimumab vs chemotherapy, in centrally confirmed MSI-H/dMMR disease (hazard ratio 0.21). |
| 23.7 vs 20.6 months | CheckMate-9DW · NCT04039607 Median overall survival, first-line combined with ipilimumab vs investigator-selected of lenvatinib or sorafenib (hazard ratio 0.79). |
| 22.4 vs 11.0 months | CheckMate-577 · NCT02743494 Median disease-free survival as adjuvant treatment vs placebo (hazard ratio 0.69). |
| 15.4 vs 9.1 months | CheckMate-648 Median overall survival, first-line combined with chemotherapy vs chemotherapy alone, in PD-L1-expressing squamous cell carcinoma (hazard ratio 0.54). |
Approved for advanced or metastatic disease that expresses PD-L1, combined with chemotherapy, as first-line treatment.
| 14.4 vs 11.1 months | CheckMate-649 · NCT02872116 Median overall survival, combined with chemotherapy vs chemotherapy alone, in tumors with PD-L1 combined positive score ≥5 (hazard ratio 0.71). |
This is the approval that most clearly distinguishes this drug from other checkpoint inhibitors — it is the only PD-1 inhibitor combination approved as first-line treatment for unresectable malignant pleural mesothelioma.
| 18.1 vs 14.1 months | CheckMate-743 · NCT02899299 Median overall survival, combined with ipilimumab vs chemotherapy (hazard ratio 0.74). The benefit was larger in non-epithelioid tumors (hazard ratio 0.46) than in epithelioid tumors (hazard ratio 0.85). |
This is an intravenous infusion, given at a hospital or infusion center — not a tablet taken at home. Because the dose, schedule and combination partner all depend on the specific cancer and treatment line, the table below gives typical examples rather than an exhaustive list.
| Example regimen | Used in |
|---|---|
| 240 mg every 2 weeks, or 480 mg every 4 weeks, alone | Several single-agent uses across multiple cancers |
| 360 mg every 3 weeks, combined with chemotherapy | First-line NSCLC, urothelial carcinoma, esophageal and gastric cancers |
| Combined with ipilimumab on a separate schedule (often every 3 or 6 weeks) for a fixed number of doses, then continued alone | Melanoma, RCC, mesothelioma, HCC, colorectal cancer (MSI-H/dMMR) |
Because this drug works by releasing a brake on the immune system, that same immune system can turn against healthy tissue — the lungs, gut, liver, hormone glands, skin, kidneys, or other organs. These reactions are called immune-mediated adverse reactions, and they are the defining safety concern for this entire class of drug, not a rare footnote.
These reactions can appear at any point during treatment, and sometimes even after it has stopped. Blood tests to check liver enzymes, kidney function and thyroid hormones are done before starting and periodically throughout treatment specifically to catch these early. Most immune-mediated reactions are managed by pausing treatment and, if needed, giving corticosteroids — but severe cases can require permanently stopping treatment.
Reported in at least one in five patients, depending on whether it is used alone or in combination:

This is a hospital-administered, prescription-only infusion, typically given in an oncology day-care unit. Where it is registered and reimbursed, that logistics chain is usually already in place. In many other countries, though, it may not be launched yet, may only be approved for some of its eleven indications, or the cost may be well beyond what a family can absorb without support.

Eleven cancer types currently carry FDA approvals: non-small cell lung cancer, melanoma, renal cell carcinoma, classical Hodgkin lymphoma, head and neck squamous cell carcinoma, urothelial carcinoma, MSI-H/dMMR colorectal cancer, hepatocellular carcinoma, esophageal cancer, gastric/gastroesophageal junction/esophageal adenocarcinoma, and malignant pleural mesothelioma. The exact approved setting (first-line, after surgery, after other treatment) differs by cancer.
No. It is an immunotherapy — specifically a PD-1 checkpoint inhibitor. Rather than killing dividing cells directly the way chemotherapy does, it releases a brake on the patient's own immune system so T-cells can recognize and attack the tumor. It is sometimes combined with chemotherapy, but it is not chemotherapy itself.
In most approved settings, no trial has described it as a cure — the goal is longer disease control or longer survival. In a few adjuvant settings (after surgery, such as in melanoma, urothelial or esophageal cancer), it is used specifically to reduce the chance the cancer comes back, which is a different goal than treating existing metastatic disease.
As an intravenous infusion at a hospital or infusion center, typically every 2, 3 or 4 weeks depending on the regimen. It is not a tablet and cannot be taken at home.
Immune-mediated side effects, where the activated immune system attacks healthy organs — commonly the lungs, gut, liver, skin, kidneys or hormone glands. These can appear at any time during treatment or after stopping, which is why regular blood monitoring is part of routine care.
Combinations can produce a stronger response than either drug alone by attacking the tumor through more than one immune pathway, or by pairing immune activation with direct tumor cell killing. Combinations also generally carry a higher rate of side effects, so the specific pairing used depends on the approved indication for that cancer.
It depends on the cancer. Some approvals require PD-L1 testing on the tumor; the colorectal cancer approval requires MSI-H or dMMR status specifically. Other uses do not require a biomarker test at all. Ask your oncologist which applies to your specific diagnosis.
It varies by cancer and setting — some regimens run for a fixed period (often up to two years), while others continue until the disease progresses or side effects become unacceptable. Your oncologist will specify the plan for your particular indication.
Yes, in specific settings. In advanced renal cell carcinoma, it is approved in combination with the targeted drug cabozantinib as a first-line option.
Fatigue, rash, joint or muscle pain, itching, diarrhea, nausea, reduced appetite, cough and fever are the most frequently reported, whether used alone or in combination.
They are in the same drug class (PD-1 inhibitors) and often used in similar clinical situations, but each has its own set of FDA-approved indications, trial data and dosing. They are not interchangeable without a specific reason, and the choice between them is made by the treating oncologist based on the approved indication for the cancer in question.
Often, yes — though it depends on the destination country's import rules, cold-chain logistics, the prescription on file, and whether the product is already registered there. Ikris Pharma Network coordinates the documentation and logistics. Share your country and requirement, and we will tell you what is realistic.
