Teratogenicity Pomalidomide must not be taken during pregnancy, since a teratogenic effect is expected. Pomalidomide is structurally related to thalidomide. Thalidomide is a known human teratogen that causes severe life-threatening birth defects.
3). The conditions of the Pregnancy Prevention Programme must be fulfilled for all patients unless there is reliable evidence that the patient does not have childbearing potential. Criteria for women of non-childbearing potential A female patient or a female partner of a male patient is considered of non-childbearing potential if she meets at least one of the following criteria: • Age ≥ 50 years and naturally amenorrhoeic for ≥ 1 year (amenorrhoea following cancer therapy or during breast-feeding does not rule out childbearing potential) • Premature ovarian failure confirmed by a specialist gynaecologist • Previous bilateral salpingo-oophorectomy, or hysterectomy • XY genotype, Turner syndrome, uterine agenesis.
Counselling For women of childbearing potential, pomalidomide is contraindicated unless all of the following are met: • She understands the expected teratogenic risk to the unborn child • She understands the need for effective contraception, without interruption, at least 4 weeks before starting treatment, throughout the entire duration of treatment, and at least 4 weeks after the end of treatment • Even if a woman of childbearing potential has amenorrhoea she must follow all the advice on effective contraception • She should be capable of complying with effective contraceptive measures • She is informed and understands the potential consequences of pregnancy and the need to rapidly consult if there is a risk of pregnancy • She understands the need to commence the treatment as soon as pomalidomide is dispensed following a negative pregnancy test • She understands the need and accepts to undergo pregnancy testing at least every 4 weeks except in case of confirmed tubal sterilisation • She acknowledges that she understands the hazards and necessary precautions associated with the use of pomalidomide.

If adverse reactions occur after dose reductions to 1mg, then the treatment should be discontinued. g. 2). Bortezomib dose modification or interruption For instructions on dose interruptions or reductions for bortezomib related adverse reactions, physicians should refer to bortezomib Summary of Product Characteristics (SmPC).
Dexamethasone dose modification or interruption Instructions on dose interruptions or reductions for low-dose dexamethasone related adverse reactions are outlined in Tables 4 and 5 below. However, dose interruption or resumption decisions are at the physician’s discretion per Summary of Product Characteristics (SmPC).
Table 4. Dexamethasone dose modification instructions Toxicity Dose Modification Toxicity Dose Modification Dyspepsia = Grade 1-2 Maintain dose and treat with histamine (H2) blockers or equivalent. Decrease by one dose level if symptoms persist.
Dyspepsia ≥ Grade 3 Interrupt dose until symptoms are controlled. Add H2 blocker or equivalent and resume at one dose level lower than previous dose. Oedema ≥ Grade 3 Use diuretics as needed and decrease dose by one dose level. Confusion or mood alteration ≥ Grade 2 Interrupt dose until symptoms resolve.
Resume at one dose level lower than previous dose. Muscle weakness ≥ Grade 2 Interrupt dose until muscle weakness ≤ Grade 1. Resume at one dose level lower than previous dose. Hyperglycaemia ≥ Grade 3 Decrease dose by one dose level. Treat with insulin or oral hypoglycaemic agents as needed.

The prescriber must ensure that for women of childbearing potential: • The patient complies with the conditions of the Pregnancy Prevention Programme, including confirmation that she has an adequate level of understanding • The patient has acknowledged the aforementioned conditions.
For male patients taking pomalidomide, pharmacokinetic data has demonstrated that pomalidomide is present in human semen during treatment. As a precaution, and taking into account special populations with potentially prolonged elimination time such as hepatic impairment, all male patients taking pomalidomide must meet the following conditions: • He understands the expected teratogenic risk if engaged in sexual activity with a pregnant woman or a woman of childbearing potential • He understands the need for the use of a condom if engaged in sexual activity with a pregnant woman or a woman of childbearing potential not using effective contraception, throughout treatment duration, during dose interruption and for 7 days after dose interruptions and/or cessation of treatment.
This includes vasectomised males who should wear a condom if engaged in sexual activity with a pregnant woman or a woman of childbearing potential as seminal fluid may still contain pomalidomide in the absence of spermatozoa. • He understands that if his female partner becomes pregnant whilst he is taking pomalidomide or 7 days after he has stopped taking pomalidomide, he should inform his treating physician immediately and that it is recommended to refer the female partner to a physician specialised or experienced in teratology for evaluation and advice.
Contraception Women of childbearing potential must use at least one effective method of contraception for at least 4 weeks before therapy, during therapy, and until at least 4 weeks after pomalidomide therapy and even in case of dose interruption unless the patient commits to absolute and continuous abstinence confirmed on a monthly basis.
If not established on effective contraception, the patient must be referred to an appropriately trained health care professional for contraceptive advice in order that contraception can be initiated. e. 5). If a patient is currently using combined oral contraception the patient should switch to one of the effective methods listed above.
The risk of venous thromboembolism continues for 4-6 weeks after discontinuing combined oral contraception. 5). Implants and levonorgestrel-releasing intrauterine systems are associated with an increased risk of infection at the time of insertion and irregular vaginal bleeding.
Prophylactic antibiotics should be considered particularly in patients with neutropenia. Insertion of copper-releasing intrauterine devices is not recommended due to the potential risks of infection at the time of insertion and menstrual blood loss which may compromise patients with severe neutropenia or severe thrombocytopenia.
Pregnancy testing According to local practice, medically supervised pregnancy tests with a minimum sensitivity of 25 mIU/mL must be performed for women of […]
