5 Warnings and Precautions

WARNINGS AND PRECAUTIONS

5.1 Neutropenia

Additions and/or revisions underlined:

TRODELVY can cause severe, life-threatening, or fatal neutropenia as early as the first cycle of treatment. Neutropenia occurred in 64% of patients treated with TRODELVY. Grade 3-4 neutropenia occurred in 49% of patients. Febrile neutropenia occurred in 6% of patients. The median time to first onset of neutropenia (including febrile neutropenia) was 16 days (range: 1 to 435 days). Neutropenia occurred earlier in patients with reduced UGT1A1 activity [see Warnings and Precautions (5.5)]. Neutropenic colitis occurred in 1.4% of patients.

Primary prophylaxis with G-CSF is recommended starting in the first cycle of treatment in all patients at increased risk of febrile neutropenia, including older patients, patients with previous neutropenia, poor performance status, organ dysfunction, or multiple comorbidities.

Monitor absolute neutrophil count (ANC) during treatment. Withhold TRODELVY for ANC below 1500/mm3 on Day 1 of any cycle or below 1000/mm3 on Day 8 of any cycle. Withhold TRODELVY for neutropenic fever. Dose modifications may be required due to neutropenia. Treat neutropenia with G-CSF and administer prophylaxis in subsequent cycles as clinically indicated or indicated in Table 2 [see Dosage and Administration (2.3)].


5.4 Nausea and Vomiting

Additions and/or revisions underlined:

TRODELVY is emetogenic and can cause severe nausea and vomiting. Nausea occurred in 64% of all patients treated with TRODELVY. Grade 3-4 nausea occurred in 3% of patients.

PATIENT INFORMATION

Additions and/or revisions underlined:

What is the most important information I should know about TRODELVY? TRODELVY can cause serious side effects, including:

  • Low white blood cell count (neutropenia). Low white blood cell counts are common with TRODELVY and can sometimes be severe and lead to infections that can be life-threatening or cause death as early as the first cycle of treatment. Your healthcare provider should check your blood cell counts during treatment with TRODELVY and may give a medicine to help prevent low blood cell count starting in the first cycle of treatment if you have an increased risk for developing low white blood cell count with a fever (febrile neutropenia). If your white blood cell count is too low, your healthcare provider may need to delay treatment or lower your dose of TRODELVY, give you a medicine to treat low blood cell count, or in some cases may permanently stop TRODELVY. Your healthcare provider may need to give you antibiotic medicines if you develop fever while your white blood cell count is low.

. . .

  • Severe diarrhea. Diarrhea is common with TRODELVY and can also be severe. Severe diarrhea can lead to loss of too much body fluid (dehydration) and kidney problems. Your healthcare provider should monitor you for diarrhea and give you medicine as needed to help control your diarrhea. If you lose too much body fluid, your healthcare provider may need to give you fluids and electrolytes to replace body salts. If you develop diarrhea during treatment with TRODELVY, your healthcare provider should check to see if diarrhea may be caused by an infection. Your healthcare provider may decrease your dose, delay treatment, or permanently stop TRODELVY if your diarrhea is severe and cannot be controlled with anti-diarrheal medicines.

. . .

  • Nausea and vomiting. Nausea and vomiting are common with TRODELVY and can sometimes be severe. Before each dose of TRODELVY, you will receive medicines to help prevent nausea and vomiting. You should be given medicines to take home with you, along with instructions about how to take them to help prevent and treat any nausea and vomiting after you receive TRODELVY. Call your healthcare provider right away if you have nausea or vomiting that is not controlled with the medicines prescribed for you. Your healthcare provider may decide to decrease your dose, delay treatment, or permanently stop TRODELVY if your nausea and vomiting is severe and cannot be controlled with anti-nausea medicines.

5.5 Increased Risk of Adverse Reactions in Patients with Reduced UGT1A1 Activity

Additions and/or revisions underlined:

Patients homozygous for the uridine diphosphate-glucuronosyl transferase 1A1 (UGT1A1)*28 allele are at increased risk for neutropenia, febrile neutropenia, and anemia; and may be at increased risk for other adverse reactions when treated with TRODELVY.

The incidence of neutropenia and anemia was analyzed in 948 patients who received TRODELVY and had UGT1A1 genotype results. In patients homozygous for the UGT1A1 *28 allele (n=112), the incidence of Grade 3-4 neutropenia was 58%. In patients heterozygous for the UGT1A1*28 allele (n=420), the incidence of Grade 3-4 neutropenia was 49%. In patients homozygous for the wild-type allele (n=416), the incidence of Grade 3-4 neutropenia was 43% [see Clinical Pharmacology (12.5)]. In patients homozygous for the UGT1A1 *28 allele, the incidence of Grade 3-4 anemia was 21%. In patients heterozygous for the UGT1A1*28 allele, the incidence of Grade 3-4 anemia was 10%. In patients homozygous for the wild-type allele, the incidence of Grade 3-4 anemia was 9%.

The median time to first neutropenia including febrile neutropenia was 9 days in patients homozygous for the UGT1A1*28 allele, 15 days in patients heterozygous for the UGT1A1*28 allele, and 20 days in patients homozygous for the wild-type allele. The median time to first anemia was 21 days in patients homozygous for the UGT1A1*28 allele, 25 days in patients heterozygous for the UGT1A1*28 allele, and 28 days in patients homozygous for the wild-type allele.

Closely monitor patients with known reduced UGT1A1 activity for adverse reactions. Withhold or permanently discontinue TRODELVY based on clinical assessment of the onset, duration and severity of the observed adverse reactions in patients with evidence of acute early-onset or unusually severe adverse reactions, which may indicate reduced UGT1A1 enzyme activity [see Dosage and Administration (2.3)].
