Pomalidomide, an analogue of thalidomide, is an immunomodulatory antineoplastic agent. FDA approved on February 8, 2013.


Pomalidomide is indicated for patients with multiple myeloma who have received at least two prior therapies including lenalidomide and bortezomib and have demonstrated disease progression on or within 60 days of completion of the last therapy.

Mechanism of Action

Promalidomide is an immunomodulatory agent with antineoplastic activity. It is shown to inhibit the proliferation and induce apoptosis of various tumour cells. Furthermore, promalidomide enhances T cell and natural killer (NK) cell-mediated immunity and inhibited the production of pro-inflammatory cytokines, like TNF-alpha or IL-6, by monocytes. The primary target of promalidomide is thought to be the protein cereblon. It binds to this target and inhibits ubiquitin ligase activity. It is also a transcriptional inhibitor of COX2.


Pomalidomide is generally well absorbed. The major circulating component is the parent compound. Tmax, single oral dose = 2 -3 hours. When 4 mg of promalidomide is given to patients with multiple myeloma, the steady-state pharmacokinetic parameters are as follows: AUC(T) = 400 ng.hr/mL; Cmax = 75 ng/mL. Promalidomide accumulates following multiple doses.
Mean apparent volume of distribution (Vd/F), steady-state = 62 - 138 L
Promalidomide is hepatically metabolized by CYP1A2 and CYP3A4. The metabolites are 26-fold less active than the parent compound. Minor contributions from CYP2C19 and CYP2D6 have been observed in vitro.


Total body clearance = 7-10 L/hour


Most common adverse reactions (≥30%) included fatigue and asthenia, neutropenia, anemia, constipation, nausea, diarrhea, dyspnea, upper-respiratory tract infections, back pain and pyrexia.
