oIncludes myositis reported in an ongoing trial of dostarlimab in combination, and immune-mediated myositis (monotherapy pool); estimated frequency category.
plncludes nephritis and tubulointerstitial nephritis.
qlncludes transaminases increased, alanine aminotransferases increased, aspartate aminotransferases increased, and hypertransaminasaemia.
rIncludes alanine aminotransferase increased, aspartate aminotransferase increased and transaminases increased.
sIncludes infusion-related reaction and hypersensitivity.
The Discontinuation Rate Due to Adverse Reactions Was Low at 6.3%, With a Median Follow-Up of 27.6 Months1
- Most common adverse reactions in at least 10% of patients were anaemia, diarrhoea, nausea, vomiting, arthralgia, pruritus, rash, pyrexia, aspartate aminotransferase increased, and hypothyroidism1
- Some additional uncommon adverse reactions in patients treated with dostarlimab, such as myasthenic syndrome, systemic inflammatory response syndrome, and myocarditis (including immune-mediated myocarditis), were reported from ongoing category trials of dostarlimab in combination, and the frequency is estimated1
- All patients recovered from infusion-related reactions1
- Treatment-related adverse events did not increase after Q3W-to-Q6W dose transition2
The safety of JEMPERLI has been evaluated in 605 patients with endometrial cancer or other advanced solid tumours who received JEMPERLI monotherapy in the GARNET study, including 153 patients with recurrent/advanced dMMR/MSI-H endometrial cancer. Patients received doses of 500 mg every 3 weeks for 4 cycles followed by 1000 mg every 6 weeks for all cycles thereafter.1
In recurrent/advanced post-platinum dMMR/MSI-H EC
A Low Incidence of Grade 3 irARs Supports the Manageable Safety Profile of JEMPERLI1


Immune-related adverse reactions (irARs) were generally manageable for JEMPERLI1*
- There was 1 reported incident of a Grade 4 event (immune-related pneumonitis)
*The majority of JEMPERLI treatment discontinuations and serious adverse reactions were due to immune-related events. The rate of discontinuation due to adverse reactions was 6.3%, and the rate of serious adverse reactions was 11.2%.1
