SPECIAL WARNINGS AND PRECAUTIONS FOR USE
Immune-mediated Adverse Reactions
Immune-mediated adverse reactions including severe and fatal cases, have occurred in patients receiving KEYTRUDA. In clinical trials, most immune-mediated adverse reactions occurred during treatment, were reversible and managed with interruptions of KEYTRUDA, administration of corticosteroids and/or supportive care. Immune-related adverse reactions have also occurred after the last dose of KEYTRUDA. Immune-mediated adverse reactions affecting more than one body system can occur simultaneously.
For suspected immune-mediated adverse reactions, ensure adequate evaluation to confirm aetiology or exclude other causes. Based on the severity of the adverse reaction, withhold KEYTRUDA and consider administration of corticosteroids. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Based on limited data from clinical studies in patients whose immune-related adverse reactions could not be controlled with corticosteroid use, administration of other systemic immunosuppressants can be considered. Restart KEYTRUDA if the adverse reaction remains at Grade 1 or less following corticosteroid taper. If another episode of a severe adverse reaction occurs, permanently discontinue KEYTRUDA.
Withhold or discontinue KEYTRUDA to manage adverse reactions as described in the Data Sheet. No dose reductions of KEYTRUDA are recommended.
Immune-mediated pneumonitis
Pneumonitis (including fatal cases) has been reported in patients receiving KEYTRUDA. Monitor patients for signs and symptoms of pneumonitis. If pneumonitis is suspected, evaluate with radiographic imaging and exclude other causes.
Immune-mediated colitis
Colitis has been reported in patients receiving KEYTRUDA. Monitor patients for signs and symptoms of colitis and exclude other causes.
Immune-mediated hepatitis
Hepatitis has been reported in patients receiving KEYTRUDA. Monitor patients for changes in liver function (at the start of treatment, periodically during treatment and as indicated based on clinical evaluation) and symptoms of hepatitis and exclude other causes.
Immune-mediated nephritis
Nephritis has been reported in patients receiving KEYTRUDA. Monitor patients for changes in renal function and exclude other causes.
Immune-mediated endocrinopathies
Adrenal insufficiency (primary and secondary) and hypophysitis has been reported in patients receiving KEYTRUDA. Monitor patients for signs and symptoms of adrenal insufficiency and hypophysitis (including hypopituitarism) and exclude other causes.
Type 1 diabetes mellitus, including diabetic ketoacidosis, has been reported in patients receiving KEYTRUDA. Monitor patients for hyperglycaemia or other signs and symptoms of diabetes.
Thyroid disorders, including hyperthyroidism, hypothyroidism and thyroiditis, have been reported in patients receiving KEYTRUDA and can occur at any time during treatment, therefore monitor patients for changes in thyroid function and clinical signs and symptoms of thyroid disorders.
Severe skin reactions
Immune-mediated severe skin reactions have been reported in patients treated with KEYTRUDA. Monitor patients for suspected severe skin reactions and exclude other causes. Cases of Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and bullous pemphigoid have been reported in patients treated with KEYTRUDA. Some cases of SJS and TEN have had a fatal outcome.
Other immune-mediated adverse reactions
The following additional clinically significant, immune-mediated adverse reactions were reported in less than 1% of patients treated with KEYTRUDA in KEYNOTE-001, KEYNOTE-002, KEYNOTE-006, and KEYNOTE-010: uveitis, myositis, Guillain-Barre syndrome, pancreatitis, encephalitis, sarcoidosis, myasthenic syndrome/myasthenia gravis (including exacerbation), myelitis, vasculitis, hypoparathyroidism, gastritis, haemolytic anaemia and pericarditis. The following was reported in other clinical studies with KEYTRUDA or in post-marketing use: myocarditis, sclerosing cholangitis and exocrine pancreatic insufficiency.
Transplant-related adverse reactions
Solid organ transplant rejection has been reported in the post-marketing setting in patients treated with KEYTRUDA. Treatment with KEYTRUDA may increase the risk of rejection in solid organ transplant recipients. Consider the benefit of treatment with KEYTRUDA versus the risk of possible organ rejection in these patients.
Acute graft-versus-host-disease (GVHD), including fatal GVHD, after treatment with KEYTRUDA has been reported in patients with a history of allogeneic hematopoietic stem cell transplant (HSCT). Patients who experienced GVHD after their transplant procedure may be at increased risk for GVHD after treatment with KEYTRUDA. Consider the benefit of treatment with KEYTRUDA versus the risk of possible GVHD in patients with a history of allogeneic HSCT.
Elevated liver enzymes when KEYTRUDA is given in combination with axitinib for RCC
When KEYTRUDA is given with axitinib, higher than expected frequencies of Grades 3 and 4 ALT and AST elevations have been reported in patients with advanced RCC. Monitor liver enzymes before initiation of and periodically throughout treatment. Consider more frequent monitoring of liver enzymes as compared to when the drugs are used in monotherapy. Follow medical management guidelines for both drugs. Refer to the prescribing information for axitinib.
Increased mortality in patients with multiple myeloma when KEYTRUDA is added to a thalidomide analogue and dexamethasone
In two randomised clinical trials in patients with multiple myeloma, the addition of KEYTRUDA to a thalidomide analogue plus dexamethasone, a use for which no PD-1 or PD-L1 blocking antibody is indicated, resulted in increased mortality. Treatment of patients with multiple myeloma with a PD-1 or PD-L1 blocking antibody in combination with a thalidomide analogue plus dexamethasone is not recommended outside of controlled clinical trials.
Infusion-related reactions
Severe infusion reactions, including hypersensitivity and anaphylaxis, have been reported in 6 (0.2%) of 2799 patients receiving KEYTRUDA in KEYNOTE-001, KEYNOTE-002, KEYNOTE-006 and KEYNOTE-010. Patients with mild or moderate infusion reaction may continue to receive KEYTRUDA with close monitoring; premedication with antipyretic and antihistamine may be considered.
Patients excluded from clinical trials
Patients with HIV, HBV, HCV, other active infections requiring therapy; and patients with a history of severe immune-mediated adverse reactions with ipilimumab, defined as any Grade 4 toxicity requiring treatment with corticosteroids or Grade 3 toxicity requiring corticosteroid treatment (greater than 10 mg/day prednisone or equivalent dose) for greater than 12 weeks were excluded from the clinical trial. No clinical data is available. Caution should be used in these patient populations.
Patients who experienced less severe adverse reactions (including immune-mediated) on ipilimumab that resolved or improved to Grade 0-1 and ≤10 mg/day prednisone (or equivalent dose) for immune-mediated adverse events for at least two weeks prior to first dose of KEYTRUDA were included in the clinical trial. Caution should be used in this patient population.
Effect on Laboratory Tests
Thyroid and liver (hepatic transaminase and bilirubin levels) function tests should be performed at the start of treatment, periodically during treatment and as indicated based on clinical evaluation.
Effects on Fertility
Fertility studies have not been conducted with KEYTRUDA.
Use in Pregnancy (Category D) and Use in Lactation
There are no data on the use of KEYTRUDA in pregnant women. KEYTRUDA is not recommended during pregnancy unless the clinical benefit outweighs the potential risk to the foetus. Women of childbearing potential should use effective contraception during treatment with KEYTRUDA and for at least 4 months following the last dose of KEYTRUDA.
It is unknown whether KEYTRUDA is secreted in human milk. A decision should be made whether to discontinue breast-feeding or to discontinue KEYTRUDA.
Effects on ability to drive and use machines
Because of potential adverse reactions such as fatigue, patients should be advised to use caution when driving or operating machinery until they are certain that KEYTRUDA does not adversely affect them.
CONTRAINDICATIONS
Hypersensitivity to the active substance or to any of the excipients; Histidine, Histidine monohydrochloride monohydrate, Sucrose, Polysorbate 80 and water for injection.
INTERACTIONS WITH OTHER MEDICINES
No formal pharmacokinetic drug interaction studies have been conducted with KEYTRUDA. The use of systemic corticosteroids or immunosuppressants before starting KEYTRUDA should be avoided, however, systemic corticosteroids or other immunosuppressants can be used after starting KEYTRUDA to treat immune-mediated adverse reactions. Corticosteroids can also be used as premedication, when Keytruda is used in combination with chemotherapy, as antiemetic prophylaxis and/or to alleviate chemotherapy-related adverse reactions.
ADVERSE EFFECTS
Clinical trials experience
The safety of KEYTRUDA was evaluated in 2799 patients with melanoma and NSCLC in controlled and uncontrolled studies. The median treatment duration was 4.2 months (range 1 day to 30.4 months) including 1153 patients treated for greater than or equal to six months and 600 patients treated for greater than or equal to one year.
KEYTRUDA was discontinued for treatment-related adverse reactions in 5% of patients. Treatment-related serious adverse events (SAEs) reported up to 90 days after the last dose occurred in 10% of patients receiving KEYTRUDA. Of these treatment-related SAEs, the most common were: pneumonitis, colitis, diarrhoea, and pyrexia. The most common treatment-related adverse reactions (reported in >10% of patients) were: fatigue, pruritus, rash, diarrhoea, and nausea.

DOSAGE AND ADMINISTRATION
Recommended Dosing
KEYTRUDA is administered as an intravenous infusion over 30 minutes. The recommended dose of KEYTRUDA in adults is:
- 200 mg every 3 weeks or
- 400 mg every 6 weeks
The recommended dose of KEYTRUDA in paediatric patients is 2 mg/kg (up to a maximum of 200 mg) every 3 weeks.
For use in combination, please review the Data Sheets for KEYTRUDA and the relevant concomitant therapies. When administering KEYTRUDA as part of a combination with intravenous chemotherapy, KEYTRUDA should be administered first.
Patients should be treated with KEYTRUDA until disease progression or unacceptable toxicity. Atypical responses (i.e., an initial transient increase in tumour size or small new lesions within the first few months followed by tumour shrinkage) have been observed. Clinically stable patients with initial evidence of disease progression can under some circumstances remain on treatment until disease progression is confirmed.
For the adjuvant treatment of melanoma, RCC or NSCLC, KEYTRUDA should be administered for up to one year or until disease recurrence or unacceptable toxicity.
For the neoadjuvant and adjuvant treatment of high-risk early-stage TNBC, patients should be treated with neoadjuvant KEYTRUDA in combination with chemotherapy for 8 doses of 200 mg every 3 weeks or 4 doses of 400 mg every 6 weeks or until disease progression that precludes definitive surgery or unacceptable toxicity, followed by adjuvant treatment with KEYTRUDA as monotherapy for 9 doses of 200 mg every 3 weeks or 5 doses of 400 mg every 6 weeks or until disease recurrence or unacceptable toxicity. Patients who experience disease progression that precludes definitive surgery or unacceptable toxicity related to KEYTRUDA as neoadjuvant treatment in combination with chemotherapy should not receive KEYTRUDA monotherapy as adjuvant treatment.
No dose reductions of KEYTRUDA are recommended.
Use in Geriatric Patients
No overall differences in safety or efficacy were reported between elderly patients (65 years and over) and younger patients (less than 65 years). No dose adjustment is necessary in this population.
Use in patients with Renal/Hepatic Insufficiency
No dose adjustment is needed for patients with mild or moderate renal impairment, or mild hepatic impairment. KEYTRUDA has not been studied in patients with severe renal impairment, or moderate or severe hepatic impairment.

KEYTRUDA, as monotherapy, is indicated for the first-line treatment of patients with metastatic or unresectable recurrent HNSCC, whose tumours express PD-L1 [Combined Positive Score (CPS) ≥1] as determined by a validated test.
KEYTRUDA, as monotherapy, is indicated for the treatment of patients with metastatic or unresectable recurrent HNSCC with disease progression on or after platinum-containing chemotherapy.
Microsatellite instability-high cancer
Colorectal
KEYTRUDA is indicated in adult and paediatric patients for the treatment of unresectable or metastatic, microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR) colorectal cancer that has progressed following treatment with a fluoropyrimidine, oxaliplatin, and irinotecan. This indication was approved based on objective response rate and response duration in a single-arm trials.
Non-colorectal
KEYTRUDA is indicated in adult and paediatric patients for the treatment of unresectable or metastatic, MSI-H or dMMR tumours that have progressed following prior treatment and when there are no satisfactory alternative treatment options. Sample sizes for individual tissue types were too small to provide data on clinical utility of the MSI-H/dMMR tests for each of the tissue types, individually. The assumption that MSI-H/dMMR-status is predictive of the treatment effect of KEYTRUDA for every tissue type has not been verified.
The safety and effectiveness of KEYTRUDA in paediatric patients with MSI-H central nervous system cancers have not been established.

SPECIAL WARNINGS AND PRECAUTIONS FOR USE
Immune-mediated Adverse Reactions
Immune-mediated adverse reactions including severe and fatal cases, have occurred in patients receiving KEYTRUDA. In clinical trials, most immune-mediated adverse reactions occurred during treatment, were reversible and managed with interruptions of KEYTRUDA, administration of corticosteroids and/or supportive care. Immune-related adverse reactions have also occurred after the last dose of KEYTRUDA. Immune-mediated adverse reactions affecting more than one body system can occur simultaneously.
For suspected immune-mediated adverse reactions, ensure adequate evaluation to confirm aetiology or exclude other causes. Based on the severity of the adverse reaction, withhold KEYTRUDA and consider administration of corticosteroids. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Based on limited data from clinical studies in patients whose immune-related adverse reactions could not be controlled with corticosteroid use, administration of other systemic immunosuppressants can be considered. Restart KEYTRUDA if the adverse reaction remains at Grade 1 or less following corticosteroid taper. If another episode of a severe adverse reaction occurs, permanently discontinue KEYTRUDA.
Withhold or discontinue KEYTRUDA to manage adverse reactions as described in the Data Sheet. No dose reductions of KEYTRUDA are recommended.
Immune-mediated pneumonitis
Pneumonitis (including fatal cases) has been reported in patients receiving KEYTRUDA. Monitor patients for signs and symptoms of pneumonitis. If pneumonitis is suspected, evaluate with radiographic imaging and exclude other causes.
Immune-mediated colitis
Colitis has been reported in patients receiving KEYTRUDA. Monitor patients for signs and symptoms of colitis and exclude other causes.
Immune-mediated hepatitis
Hepatitis has been reported in patients receiving KEYTRUDA. Monitor patients for changes in liver function (at the start of treatment, periodically during treatment and as indicated based on clinical evaluation) and symptoms of hepatitis and exclude other causes.
Immune-mediated nephritis
Nephritis has been reported in patients receiving KEYTRUDA. Monitor patients for changes in renal function and exclude other causes.
Immune-mediated endocrinopathies
Adrenal insufficiency (primary and secondary) and hypophysitis has been reported in patients receiving KEYTRUDA. Monitor patients for signs and symptoms of adrenal insufficiency and hypophysitis (including hypopituitarism) and exclude other causes.
Type 1 diabetes mellitus, including diabetic ketoacidosis, has been reported in patients receiving KEYTRUDA. Monitor patients for hyperglycaemia or other signs and symptoms of diabetes.
Thyroid disorders, including hyperthyroidism, hypothyroidism and thyroiditis, have been reported in patients receiving KEYTRUDA and can occur at any time during treatment, therefore monitor patients for changes in thyroid function and clinical signs and symptoms of thyroid disorders.
Severe skin reactions
Immune-mediated severe skin reactions have been reported in patients treated with KEYTRUDA. Monitor patients for suspected severe skin reactions and exclude other causes. Cases of Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and bullous pemphigoid have been reported in patients treated with KEYTRUDA. Some cases of SJS and TEN have had a fatal outcome.
Other immune-mediated adverse reactions
The following additional clinically significant, immune-mediated adverse reactions were reported in less than 1% of patients treated with KEYTRUDA in KEYNOTE-001, KEYNOTE-002, KEYNOTE-006, and KEYNOTE-010: uveitis, myositis, Guillain-Barre syndrome, pancreatitis, encephalitis, sarcoidosis, myasthenic syndrome/myasthenia gravis (including exacerbation), myelitis, vasculitis, hypoparathyroidism, gastritis, haemolytic anaemia and pericarditis. The following was reported in other clinical studies with KEYTRUDA or in post-marketing use: myocarditis, sclerosing cholangitis and exocrine pancreatic insufficiency.
Transplant-related adverse reactions
Solid organ transplant rejection has been reported in the post-marketing setting in patients treated with KEYTRUDA. Treatment with KEYTRUDA may increase the risk of rejection in solid organ transplant recipients. Consider the benefit of treatment with KEYTRUDA versus the risk of possible organ rejection in these patients.
Acute graft-versus-host-disease (GVHD), including fatal GVHD, after treatment with KEYTRUDA has been reported in patients with a history of allogeneic hematopoietic stem cell transplant (HSCT). Patients who experienced GVHD after their transplant procedure may be at increased risk for GVHD after treatment with KEYTRUDA. Consider the benefit of treatment with KEYTRUDA versus the risk of possible GVHD in patients with a history of allogeneic HSCT.
Elevated liver enzymes when KEYTRUDA is given in combination with axitinib for RCC
When KEYTRUDA is given with axitinib, higher than expected frequencies of Grades 3 and 4 ALT and AST elevations have been reported in patients with advanced RCC. Monitor liver enzymes before initiation of and periodically throughout treatment. Consider more frequent monitoring of liver enzymes as compared to when the drugs are used in monotherapy. Follow medical management guidelines for both drugs. Refer to the prescribing information for axitinib.
Increased mortality in patients with multiple myeloma when KEYTRUDA is added to a thalidomide analogue and dexamethasone
In two randomised clinical trials in patients with multiple myeloma, the addition of KEYTRUDA to a thalidomide analogue plus dexamethasone, a use for which no PD-1 or PD-L1 blocking antibody is indicated, resulted in increased mortality. Treatment of patients with multiple myeloma with a PD-1 or PD-L1 blocking antibody in combination with a thalidomide analogue plus dexamethasone is not recommended outside of controlled clinical trials.
Infusion-related reactions
Severe infusion reactions, including hypersensitivity and anaphylaxis, have been reported in 6 (0.2%) of 2799 patients receiving KEYTRUDA in KEYNOTE-001, KEYNOTE-002, KEYNOTE-006 and KEYNOTE-010. Patients with mild or moderate infusion reaction may continue to receive KEYTRUDA with close monitoring; premedication with antipyretic and antihistamine may be considered.
Patients excluded from clinical trials
Patients with HIV, HBV, HCV, other active infections requiring therapy; and patients with a history of severe immune-mediated adverse reactions with ipilimumab, defined as any Grade 4 toxicity requiring treatment with corticosteroids or Grade 3 toxicity requiring corticosteroid treatment (greater than 10 mg/day prednisone or equivalent dose) for greater than 12 weeks were excluded from the clinical trial. No clinical data is available. Caution should be used in these patient populations.
Patients who experienced less severe adverse reactions (including immune-mediated) on ipilimumab that resolved or improved to Grade 0-1 and ≤10 mg/day prednisone (or equivalent dose) for immune-mediated adverse events for at least two weeks prior to first dose of KEYTRUDA were included in the clinical trial. Caution should be used in this patient population.
Effect on Laboratory Tests
Thyroid and liver (hepatic transaminase and bilirubin levels) function tests should be performed at the start of treatment, periodically during treatment and as indicated based on clinical evaluation.
Effects on Fertility
Fertility studies have not been conducted with KEYTRUDA.
Use in Pregnancy (Category D) and Use in Lactation
There are no data on the use of KEYTRUDA in pregnant women. KEYTRUDA is not recommended during pregnancy unless the clinical benefit outweighs the potential risk to the foetus. Women of childbearing potential should use effective contraception during treatment with KEYTRUDA and for at least 4 months following the last dose of KEYTRUDA.
It is unknown whether KEYTRUDA is secreted in human milk. A decision should be made whether to discontinue breast-feeding or to discontinue KEYTRUDA.
Effects on ability to drive and use machines
Because of potential adverse reactions such as fatigue, patients should be advised to use caution when driving or operating machinery until they are certain that KEYTRUDA does not adversely affect them.
CONTRAINDICATIONS
Hypersensitivity to the active substance or to any of the excipients; Histidine, Histidine monohydrochloride monohydrate, Sucrose, Polysorbate 80 and water for injection.
INTERACTIONS WITH OTHER MEDICINES
No formal pharmacokinetic drug interaction studies have been conducted with KEYTRUDA. The use of systemic corticosteroids or immunosuppressants before starting KEYTRUDA should be avoided, however, systemic corticosteroids or other immunosuppressants can be used after starting KEYTRUDA to treat immune-mediated adverse reactions. Corticosteroids can also be used as premedication, when Keytruda is used in combination with chemotherapy, as antiemetic prophylaxis and/or to alleviate chemotherapy-related adverse reactions.
ADVERSE EFFECTS
Clinical trials experience
The safety of KEYTRUDA was evaluated in 2799 patients with melanoma and NSCLC in controlled and uncontrolled studies. The median treatment duration was 4.2 months (range 1 day to 30.4 months) including 1153 patients treated for greater than or equal to six months and 600 patients treated for greater than or equal to one year.
KEYTRUDA was discontinued for treatment-related adverse reactions in 5% of patients. Treatment-related serious adverse events (SAEs) reported up to 90 days after the last dose occurred in 10% of patients receiving KEYTRUDA. Of these treatment-related SAEs, the most common were: pneumonitis, colitis, diarrhoea, and pyrexia. The most common treatment-related adverse reactions (reported in >10% of patients) were: fatigue, pruritus, rash, diarrhoea, and nausea.

The safety profile in those paediatric patients was similar to that seen in adults treated with pembrolizumab. The most common adverse reactions (reported in ≥20% of paediatric patients) were pyrexia, vomiting, headache, abdominal pain, anaemia, cough, and constipation.
DOSAGE AND ADMINISTRATION
Recommended Dosing
KEYTRUDA is administered as an intravenous infusion over 30 minutes. The recommended dose of KEYTRUDA in adults is:
- 200 mg every 3 weeks or
- 400 mg every 6 weeks
The recommended dose of KEYTRUDA in paediatric patients is 2 mg/kg (up to a maximum of 200 mg) every 3 weeks.
For use in combination, please review the Data Sheets for KEYTRUDA and the relevant concomitant therapies. When administering KEYTRUDA as part of a combination with intravenous chemotherapy, KEYTRUDA should be administered first.
Patients should be treated with KEYTRUDA until disease progression or unacceptable toxicity. Atypical responses (i.e., an initial transient increase in tumour size or small new lesions within the first few months followed by tumour shrinkage) have been observed. Clinically stable patients with initial evidence of disease progression can under some circumstances remain on treatment until disease progression is confirmed.
For the adjuvant treatment of melanoma, RCC or NSCLC, KEYTRUDA should be administered for up to one year or until disease recurrence or unacceptable toxicity.
For the neoadjuvant and adjuvant treatment of high-risk early-stage TNBC, patients should be treated with neoadjuvant KEYTRUDA in combination with chemotherapy for 8 doses of 200 mg every 3 weeks or 4 doses of 400 mg every 6 weeks or until disease progression that precludes definitive surgery or unacceptable toxicity, followed by adjuvant treatment with KEYTRUDA as monotherapy for 9 doses of 200 mg every 3 weeks or 5 doses of 400 mg every 6 weeks or until disease recurrence or unacceptable toxicity. Patients who experience disease progression that precludes definitive surgery or unacceptable toxicity related to KEYTRUDA as neoadjuvant treatment in combination with chemotherapy should not receive KEYTRUDA monotherapy as adjuvant treatment.
No dose reductions of KEYTRUDA are recommended.
Use in Geriatric Patients
No overall differences in safety or efficacy were reported between elderly patients (65 years and over) and younger patients (less than 65 years). No dose adjustment is necessary in this population.
Use in patients with Renal/Hepatic Insufficiency
No dose adjustment is needed for patients with mild or moderate renal impairment, or mild hepatic impairment. KEYTRUDA has not been studied in patients with severe renal impairment, or moderate or severe hepatic impairment.
