Uses
1 INDICATIONS AND USAGE JEMPERLI is a programmed death receptor-1 (PD-1)–blocking antibody indicated: Endometrial Cancer • in combination with carboplatin and paclitaxel, followed by JEMPERLI as a single agent, for the treatment of adult patients with primary advanced or recurrent endometrial cancer (EC). ( 1.1 ) • as a single agent for the treatment of adult patients with mismatch repair deficient (dMMR) recurrent or advanced EC, as determined by an FDA-approved test, that has progressed on or following prior treatment with a platinum-containing regimen in any setting and are not candidates for curative surgery or radiation.
Dosage
2 DOSAGE AND ADMINISTRATION • JEMPERLI, in combination with carboplatin and paclitaxel, for primary advanced or recurrent EC: 500 mg every 3 weeks for 6 cycles followed by 1,000 mg monotherapy every 6 weeks for all cycles thereafter. ( 2.2 ) • JEMPERLI, as a single agent, for dMMR recurrent or advanced EC: 500 mg every 3 weeks for 4 cycles followed by 1,000 mg every 6 weeks for all cycles thereafter. ( 2.2 ) • JEMPERLI, as a single agent, for dMMR recurrent or advanced solid tumors: 500 mg every 3 weeks for 4 cycles followed by 1,000 mg every 6 weeks for all cycles thereafter. ( 2.2 ) • Administer as an intravenous infusion over 30 minutes. ( 2.2 ) • For complete dosing instructions, see full prescribing information.
Side Effects
6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: • Severe and fatal immune-mediated adverse reactions [see Warnings and Precautions ( 5.1 )] • Infusion-related reactions [see Warnings and Precautions ( 5.2 )] • Most common adverse reactions (≥20%), including laboratory abnormalities, with JEMPERLI in combination with carboplatin and paclitaxel in patients with EC are decreased hemoglobin, increased creatinine, peripheral neuropathy, decreased white blood cell count, fatigue, nausea, alopecia, decreased platelets, increased glucose, decreased lymphocytes, decreased magnesium, decreased neutrophils, increased aspartate aminotransferase (AST), arthralgia, rash, constipation, diarrhea, increased alanine aminotransferase (ALT),...
Warnings
5 WARNINGS AND PRECAUTIONS • Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue, including the following: immune‑mediated pneumonitis, immune-mediated colitis, immune‑mediated hepatitis, immune-mediated endocrinopathies, immune-mediated nephritis with renal dysfunction, immune‑mediated dermatologic adverse reactions, and solid organ transplant rejection. Monitor for signs and symptoms of immune‑mediated adverse reactions. Evaluate clinical chemistries, including liver enzymes, creatinine, and thyroid function, at baseline and periodically during treatment. Withhold or permanently discontinue JEMPERLI and administer corticosteroids based on the severity of reaction. 4 CONTRAINDICATIONS None. None. ( 4 )
Pregnancy
8.1 Pregnancy Risk Summary Based on its mechanism of action, JEMPERLI can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology ( 12.1 )] . There are no available data on the use of JEMPERLI in pregnant women. Animal studies have demonstrated that inhibition of the PD-1/PD-L1 pathway can lead to increased risk of immune-mediated rejection of the developing fetus resulting in fetal death (see ) .
Storage
16 HOW SUPPLIED/STORAGE AND HANDLING JEMPERLI (dostarlimab-gxly) injection is a clear to slightly opalescent, colorless to yellow solution supplied in a carton containing one 500 mg/10 mL (50 mg/mL), single-dose vial (NDC 0173-0898-03).
