Embryo-Fetal Toxicity
- Pomalidomide capsules are contraindicated in pregnancy. Pomalidomide is a thalidomide analogue. Thalidomide is a known human teratogen that causes severe birth defects or embryo-fetal death. In females of reproductive potential, obtain 2 negative pregnancy tests before starting pomalidomide treatment.
- Females of reproductive potential must use 2 forms of contraception or continuously abstain from heterosexual sex during and for 4 weeks after stopping pomalidomide treatment [see Contraindications (4), Warnings and Precautions (5.1) and Use in Specific Populations (8.1, 8.3)].
- Deep venous thrombosis (DVT), pulmonary embolism (PE), myocardial infarction, and stroke occur in patients with multiple myeloma treated with pomalidomide capsules. Prophylactic antithrombotic measures were employed in clinical trials. Thromboprophylaxis is recommended, and the choice of regimen should be based on assessment of the patient's underlying risk factors [see Warnings and Precautions (5.3)].
- ANC less than 500 per mcL or febrile neutropenia (fever greater than or equal to 38.5°C and ANC less than 1,000 per mcL)
- Withhold pomalidomide capsules until ANC is greater than or equal to 500 per mcL; follow CBC weekly.
- Resume pomalidomide capsules dose at 1 mg less than the previous dose.*
- For each subsequent drop of ANC less than 500 per mcL
- Withhold pomalidomide capsules until ANC is greater than or equal to 500 mcL.
- Resume pomalidomide capsules dose at 1 mg less than the previous dose.*
- Platelets less than 25,000 per mcL
- Withhold pomalidomide capsules until platelets are greater than or equal to 50,000 per mcL; follow CBC weekly.
- Resume pomalidomide capsules dose at 1 mg less than the previous dose*
- For each subsequent drop of platelets less than 25,000 per mcL
- Withhold pomalidomide capsules until platelets are greater than or equal to 50,000 per mcL.
- Resume pomalidomide capsules at 1 mg less than the previous dose*
Pomalidomide capsules are only available through a restricted distribution program called PS-Pomalidomide REMS [see Warnings and Precautions (5.2)]. Information about PS-Pomalidomide REMS is available at www.PS-PomalidomideREMS.com or by calling the REMS Call Center at 1-888-423-5436.
Venous and Arterial Thromboembolism
Multiple Myeloma: Dosage Modifications for Hematologic Adverse Reactions
Initiate a new cycle of pomalidomide capsules in patients with multiple myeloma (MM) when the neutrophil count is at least 500 per mcL and the platelet count is at least 50,000 per mcL.
Dosage modification for pomalidomide capsules for hematologic adverse reactions in patients with MM are summarized in Table 1.
| Adverse Reaction | Severity | Dosage Modification |
|---|---|---|
| * Permanently discontinue pomalidomide capsules if unable to tolerate 1 mg once daily. ANC= absolute neutrophil count | ||
Neutropenia [see Warnings and Precautions (5.5)] | ||
Thrombocytopenia [see Warnings and Precautions (5.5)] | ||
CYP1A2 inhibitors
In healthy subjects, co-administration of fluvoxamine, a strong CYP1A2 inhibitor, increased Cmax and AUC of pomalidomide by 24% and 125% respectively [see Clinical Pharmacology (12.3)]. Increased pomalidomide exposure may increase the risk of exposure related toxicities. Avoid co-administration of strong CYP1A2 inhibitors (e.g. ciprofloxacin and fluvoxamine). If co-administration is unavoidable, reduce the pomalidomide dose [see Dosage and Administration (2.6)].
