5 Warnings and Precautions

5.1 Severe and Fatal Immune-Mediated Adverse Reactions

Additions and/or revisions underlined:

JEMPERLI in Combination with Carboplatin and Paclitaxel: Hypophysitis (Grade 3) occurred in 0.4% (1/241) of patients receiving JEMPERLI in combination with carboplatin and paclitaxel. Systemic corticosteroids were required and the event resolved. JEMPERLI was withheld and the patient reinitiated treatment.

JEMPERLI as a Single Agent: Hypophysitis (Grade 2) occurred in 0.2% (1/605) of patients receiving JEMPERLI as a single agent. Systemic corticosteroids were required and the event did not resolve. JEMPERLI was withheld and the patient reinitiated treatment.

Hypothyroidism: JEMPERLI in Combination with Carboplatin and Paclitaxel: Hypothyroidism occurred in 12% (28/241) of patients receiving JEMPERLI in combination with carboplatin and paclitaxel, all of which were Grade 2. Hypothyroidism led to discontinuation of JEMPERLI in 1 patient and resolved in 18% (5/28) of patients. JEMPERLI was withheld for 5 patients and all reinitiated treatment with JEMPERLI. Thyroid hormone replacement was required for 26 of the 28 patients with hypothyroidism.

JEMPERLI as a Single Agent: Hypothyroidism occurred in 8% (46/605) of patients receiving JEMPERLI as a single agent, all of which were Grade 2. Hypothyroidism did not lead to discontinuation of JEMPERLI and resolved in 37% (17/46) of patients. JEMPERLI was withheld for 2 patients and both reinitiated treatment. Thyroid hormone replacement therapy was required for 45 of the 46 patients with hypothyroidism.

Type 1 diabetes mellitus led to withholding JEMPERLI; the patient reinitated treatment and required long-term insulin therapy.

JEMPERLI as a Single Agent: Type 1 diabetes mellitus occurred in 0.2% (1/605) of patients receiving JEMPERLI as a single agent, which was Grade 3. Type 1 diabetes mellitus did not result in treatment discontinuation and did not resolve.

6 Adverse Reactions

6.1 Clinical Trials Experience

Additions and/or revisions underlined:

The safety population described in the Warnings and Precautions for use of JEMPERLI in combination with carboplatin and paclitaxel was evaluated in 241 patients with primary advanced or recurrent endometrial cancer (EC) in the randomized, double-blind, active- controlled RUBY trial.

Mismatch Repair Deficient (dMMR) or Microsatellite Instability-High (MSI-H) Primary Advanced or Recurrent EC: JEMPERLI In Combination with Carboplatin and Paclitaxel

The safety of JEMPERLI in patients with primary advanced or recurrent dMMR/MSI-H EC was evaluated in RUBY [see Clinical Studies (14.1)]. Patients received JEMPERLI 500 mg (n = 52) or placebo (n = 65) in combination with carboplatin and paclitaxel every 3 weeks for 6 doses followed by JEMPERLI 1,000 mg or placebo every 6 weeks until disease progression or unacceptable toxicity. Among the 52 patients, 56% were exposed for >1 year and 31% were exposed for >2 years.

Serious adverse reactions occurred in 13% of patients receiving JEMPERLI in combination with carboplatin and paclitaxel; the most common serious adverse reaction was sepsis, including urosepsis (6%). Fatal adverse reactions occurred in 6% of patients receiving JEMPERLI including septic shock (3.8%), and myelosuppression (1.9%).

In patients receiving JEMPERLI in combination with carboplatin and paclitaxel, JEMPERLI was permanently discontinued due to adverse reactions in 8 patients (15%) including 1 case (1.9%) each of rash maculo-papular, fatigue, general physical health deterioration, acute kidney injury, infusion-related reaction, keratitis, muscular weakness, and myelosuppression.

Dosage interruptions due to an adverse reaction occurred in 35% of patients who received JEMPERLI in combination with carboplatin and paclitaxel. Adverse reactions that required dosage interruption in greater than or equal to 5% of patients who received JEMPERLI in combination with carboplatin and paclitaxel were anemia, thrombocytopenia, platelet count decreased, peripheral neuropathy, and rash.

The most common adverse reactions, including laboratory abnormalities (greater than or equal to 20%), were decreased hemoglobin, decreased white blood cell count, decreased platelets, decreased lymphocytes, increased glucose, increased alkaline phosphatase, decreased neutrophils, rash, diarrhea, increased aspartate aminotransferase, increased alanine aminotransferase, decreased sodium, hypothyroidism, and hypertension.

MEDICATION GUIDE

Additions and/or revisions underlined

What is JEMPERLI?

JEMPERLI is a prescription medicine used to treat adults with:

  • a kind of uterine cancer called endometrial cancer (EC)

    • JEMPERLI may be used in combination with the chemotherapy medicines, carboplatin and paclitaxel, and then after that JEMPERLI may be used alone:

      • when a laboratory test shows that your tumor is mismatch repair deficient (dMMR) or microsatellite instability-high (MSI-H), and

      • your cancer has spread outside your uterus (advanced) or,

      • your cancer has returned.

    • JEMPERLI may be used alone:

      • when a laboratory test shows that your tumor is mismatch repair deficient (dMMR), and

      • your cancer has returned, or it has spread (advanced EC), and

      • you have received chemotherapy that contains platinum and it did not work or is no longer working, and

      • your cancer cannot be treated by surgery or radiation.

         

  • a kind of cancer that is shown by laboratory test to be mismatch repair deficient (dMMR) solid tumor. JEMPERLI may be used to treat:

    • cancer that has returned or has spread (advanced cancer) and,

    • has progressed during treatment or after treatment, and you have no satisfactory treatment options.

      What are the possible side effects of JEMPERLI?

      JEMPERLI can cause serious side effects.

  • See “What is the most important information I should know about JEMPERLI?”

6.2 Immunogenicity

Additions and/or revisions underlined

The immunogenicity of dostarlimab was evaluated in GARNET. Treatment-emergent anti-drug antibodies (ADAs) against dostarlimab-gxly were detected in 2.1% of 384 patients who received dostarlimab-gxly at the recommended dosage. Neutralizing antibodies were detected in 1% of patients. Because of the small number of patients who developed ADAs, the effect of immunogenicity on the efficacy and safety of dostarlimab-gxly is inconclusive.
