Drugs with unknown mechanisms of action Glutarimides Immunosuppressants Phthalimides Teratogens. Thalidomide selectively inhibits tumor necrosis factor alpha production by stimulated human monocytes. NF-kappaB in the pathogenesis and treatment of multiple myeloma. In addition, dysregulation of regulatory T cells T reg have been reported, although the role of T reg in the pathophysiology of MM remains unclear. Lenalidomide has also been evaluated with Doxil, Vincristine and dexamethasone DVd in relapsed, refractory MM Baz et al , and in combination with dexamethasone in newly diagnosed MM Rajkumar et al , b. Antiangiogenic therapy is a viable option for the treatment of patients with MM since it is associated with prominent bone marrow vascularity, the degree of which correlates with prognosis. Efficacy of low-dose thalidomide and dexamethasone as first salvage regimen in multiple myeloma.

Both kmid derived by adding an amino group to the fourth carbon of the phthaloyl ring of thalidomide. Lenalidomide is currently in phase II studies in myelofibrosis with myeloid metaplasia.

Immunomodulatory Drugs (IMiDs) in Multiple Myeloma.

However, relapse rates are very high and few salvage therapies are available. Vascular endothelial growth factor and interleukin-6 in paracrine tumor-stromal cell interactions in multiple myeloma.

Immunomodulatory imide drugs IMiDs are a class of immunomodulatory drugs [1] drugs that adjust immune responses containing an imide group. Open in a separate window. Eleven out of 20 patients had cytogenetic remission, including complete miid remission in The IMiDs have many different effects on biological systems and the combination of these properties probably accounts for their antineoplastic activity.


The mechanism of T-cell co-stimulation by the IMiDs involves enhanced transcriptional activity of activated protein-1 AP-1a key driver for IL-2 production. This activity provided the rationale for the development of thalidomide analogues with the goal of enhancing antineoplastic activity while inid or inid thalidomide-associated side effects.

The primary objective of this phase I study was to assess the safety and tolerability of lenalidomide and in this regard there were no serious adverse effects attributed to treatment. Ideally this should be measured in patients naive to previous immunomodulatory drugs, with observations kmid before and after subsequent treatment with these agents.

The relative contribution of anti-inflammatory properties of Imir towards their anti-myeloma activity is uncertain. Their development was facilitated by an improved understanding in myeloma MM biology and initiated a profound shift in the therapeutic approach towards MM.

In most tumour cell lines examined thus far, lenalidomide induces expression of the cyclin-dependent kinase inhibitors p21, p27 and p15, the early growth response genes Egr-1, 2 and 3, and SPARC Secreted protein acidic and rich in cysteine.

The other grade 3 adverse event reported was neuropathy one patient Hussein et al Author manuscript; available in PMC Feb imir Impaired functionality and phenotypic profile imiid dendritic cells from patients with multiple myeloma. After a median of 81 weeks, the median duration of transfusion independence had not been reached and the median haemoglobin was Intracellular regulation of tumor necrosis factor-related apoptosis-inducing ligand-induced apoptosis in human multiple myeloma cells.


Two patients discontinued due to drug toxicity.

Immunomodulatory imide drug – Wikipedia

Here, imjd provide a review on the development of IMiDs, and explore their mechanisms of action, with a particular focus on immune modulation including their effects on regulatory T cells T regsdisruption of plasma cell PC —microenvironment interactions, and direct anti-tumour effects.

Multiple Myeloma induces immunoparesis.

Chemical structure of thalidomide and its analogues, lenalidomide CC and pomalidomide CC The second-generation IMiDs, such as lenalidomide and CC, exhibited a greatly enhanced potency for immunomodulation and antiangiogenesis imic nonclinical studies when compared with the parent compound, thalidomide.

The introduction of IMiDs has coincided with the beginning of a major shift in the understanding of effective anti-cancer treatments. NF-kappaB in the pathogenesis and treatment of multiple myeloma.

This cross-linking triggers tumour cell cytotoxicity via perforin and granzymes released by NK cells, as well as tumour cell apoptosis induced by death ligands: Views Read Edit View history.

Exp Opin Biolog Ther.

Multiple myeloma cell adhesion-induced interleukin-6 expression in bone marrow stromal cells involves activation of NF-kappa B. Thus, each molecule cannot be assumed to have the same overall biological effects or therapeutic properties as thalidomide or other IMiDs.

Grade 3 neutropenia occurred in two patients, but there was no neutropenic sepsis.

The precise mechanism of action of IMiDs in the treatment of specific diseases is not entirely clear and may differ for various diseases depending on their imidd pathobiologies.
