Pharmacological properties of thalidomide (alpha-phthalimido glutarimide), a new sedative hypnotic drug.

Thalidomide (alpha-phthalimidoglutarimide, "Distaval," "Contergan") is a new sedative hypnotic drug which produces no toxic effects when administered orally to animals in massive doses. This lack of toxicity may be due to limited absorption. The drug has a quietening effect on the central nervous system, reducing the voluntary activity of laboratory animals and promoting sleep. Unlike the barbiturate drugs it does not cause an initial excitation in mice, incoordination or narcosis. It potentiates the actions of other central nervous system depressants, in particular the barbiturates. Its sedative effects are counteracted by central nervous system stimulants. It has no deleterious side effects and does not affect the heart, respiration or autonomic nervous system.

Is there a role for tumor necrosis factor-alpha inhibitors and especially thalidomide in dermatology?

Because of the relative shortcomings and their side effects of the available anti-inflammatory drugs such as systemic nonsteroids, corticosteroids, and immunosuppressive drugs, and since tumor necrosis factor-a plays a major role in noninfectious inflammatory and autoimmune disorders, tumor necrosis factor-a inhibitory drugs and the available tumor necrosis factor-a inhibitory biologic modifying reagents are described. Among the drugs reviewed are pentoxifylline, thalidomide, etanercept, infliximab, and adalimumab. Their relative effectiveness and side effects are reported and recommendations are made.

Thalidomide as an anti-cancer agent.

Thalidomide is a glutamic acid derivative initially introduced as a sedative hypnotic nearly forty years ago. It was withdrawn following numerous reports linking it to a characteristic pattern of congenital abnormalities in babies born to mothers who used the drug for morning sickness. It has gradually been re-introduced into clinical practice over the past two decades, albeit under strict regulation, since it was found to be useful in the management of erythema nodosum leprosum and HIV wasting syndrome. Recognition of its anti-angiogenic effect led to its evaluation in the treatment of various malignancies, where angiogenesis has been shown to play an important role. Numerous clinical trials done over the past four years have confirmed the significant anti-myeloma activity of this drug. It has also shown promise in preliminary trials in the treatment of a variety of different malignant diseases. The mechanisms of its antineoplastic effects continue to be the focus of ongoing research. It has become clear that even though its anti angiogenic effects play a significant role in the anti-tumor activity, there are other properties of this drug which are responsible as well. It also possesses anti-TNF alpha activity, which has led to its evaluation in several inflammatory states. In this concise review, we briefly describe the historical background and pharmacological aspects of this drug. We have concisely reviewed the current knowledge regarding mechanisms of its anti-neoplastic activity and the results of various clinical trials in oncology.

Thalidomide plus dexamethasone is an effective salvage regimen for myeloma patients relapsing after autologous transplant.

OBJECTIVES: High-dose therapy followed by autologous transplant (AT) is the effective induction treatment for newly diagnosed multiple myeloma (MM) patients. The best salvage therapy has not been defined; treatment options include thalidomide plus dexamethasone (TD), AT and conventional chemotherapy (CC). The aim of the study was to define the best treatment option for patients relapsing after AT. PATIENTS AND METHODS: We compared the outcome of 90 MM patients treated at diagnosis with AT and then salvaged with TD (43 patients), AT (28 patients) or CC (19 patients). The major prognostic factors, the median times between diagnosis and start of salvage treatment and the progression-free survival (PFS) from diagnosis were similar among the three groups. RESULTS: The response rate was higher after salvage AT and after TD, and lower after CC (P < 0.001). TD significantly prolonged PFS from first relapse (P < 0.0001). Median PFS was 20.3 months after TD, 9 months after AT, and 4.5 months after CC. Overall survival (OS) from first relapse was significantly improved by TD (median OS 55.5 months) but not by AT (15 months) or CC (27.5 months) (P = 0.008). Multivariate analysis indicated that TD and age were the only independent risk factors associated with improved outcome. CONCLUSION: TD improved PFS and OS in myeloma patients relapsing after AT.

Vincristine, doxorubicin, and dexamethasone or thalidomide plus dexamethasone for newly diagnosed patients with multiple myeloma?

Multiple myeloma (MM) is a malignant plasma cell tumor that is distributed at multiple sites within the bone marrow compartments. High-dose dexamethasone regimens [including vincristine, doxorubicin, and dexamethasone (VAD) chemotherapy] induce rapid responses, and have resulted in improved survival for many patients when followed by intensive therapy with autologous stem cell support early in the disease course. However, VAD have several disadvantages including the need for an intravenous indwelling catheter, which predisposes patients to catheter-related sepsis and thrombosis; most of the activity of VAD was from high-dose dexamethasone component. We enrolled all patients who fulfilled entire criteria for MM during the period between January 1997 and December 2005. The present study is a descriptive, retrospective, longitudinal, and observational one. The frequency of response (CR, VGPR/NCR, and PR) in the group of thalidomide and dexamethasone was 84.3% (CR 18.75% VGPR/NCR 18.75%, and PR 46.8%) being higher than VAD, 55% (CR 16%, VGPR/NCR 5%, and PR 34%). P = 0.0005. In summary, we conclude Thal/dex is an effective therapy in newly diagnosed MM inducing objective responses in over 84.3%.

Low tolerance and high toxicity of thalidomide as maintenance therapy after double autologous stem cell transplant in multiple myeloma patients.

Although a double autologous peripheral blood stem cell transplant (APBSCT) is an effective therapy for patients (pts) with multiple myeloma and extends progression-free survival and overall survival, pts show a continued pattern of recurrent disease. The feasibility and tolerability of thalidomide (Thal) administered in the post-transplantation period as maintenance therapy was tested in 17 pts at a dose of 100 mg/d starting between 3 and 5 months after the second transplantation and continuing either until toxicity precluded further therapy or until pts had disease progression. After a median administration of 13 months (range: 3-26), 76.5% (13 pts) failed to tolerate Thal because of: transiet ischemic attack (three pts), severe fatigue (two), neutropenia (one), piastrinopenia (one), severe opportunistic infectious (two), erectile impotence (one), gastrointestinal toxicity (anorexia with weight loss one), peripheral neuropathy (two). After a median follow-up of 36 months (range: 10-59) from the second transplant, 13 patients attained a CR + near CR (with a conversion rate from 47.1% to 76.5%). In conclusion, Thal as maintenance therapy after double ASCT is associated with low feasibility and high toxicity and could prevent a lengthy use of this antineoplastic agent.

Effects of the tumour necrosis factor-alpha inhibitors pentoxifylline and thalidomide in short-term experimental oral mucositis in hamsters.

Oral mucositis is a frequent side-effect of cancer therapy. A definitive method of prophylaxis or treatment is not yet available. As pentoxifylline (PTX) and thalidomide (TLD) have been shown to inhibit cytokine synthesis, we studied the effects of these cytokine inhibitors in an experimental oral mucositis model. Oral mucositis was induced in Golden hamsters by the administration of 5-fluorouracil (5-FU) followed by mechanical trauma of the cheek pouch. On days 4, 5, 10, 12, 14 and 16, lesions induced by 5-FU were examined macroscopically and microscopically, and the presence and intensity of hyperemia, erythema, edema, inflammatory cell infiltration, hemorrhagic areas, ulcers and abscesses were recorded. Saline (control), PTX (5, 15, 45 mg kg(-1)) or TLD (10, 30, 90 mg kg(-1)) were administered daily and animals were killed on day 10 for macroscopic and histological analysis and assay of myeloperoxidase (MPO) activity. Animals were weighed daily, and total and differential leukocyte counts were performed on peripheral blood. PTX and TLD were found to reduce the macroscopic and histological parameters of oral mucositis and MPO activity. PTX and TLD also reversed peripheral neutrophilia, but only PTX prevented weight loss. The results indicate a protective effect of PTX and TLD, suggesting an important role for tumour necrosis factor-alpha (TNF-alpha) in the pathophysiology of 5-FU induced-oral mucositis in hamsters.

Successful thalidomide therapy for actinic prurigo in a European woman.

Actinic prurigo is a rare, often difficult-to-treat, idiopathic photodermatosis. Actinic prurigo is divided into a hereditary form appearing in the Native American population and a sporadic form occurring in non-Native Americans. We present a 28-year-old Caucasian woman who developed typical clinical signs and symptoms of actinic prurigo, just as had her mother and grandmother. The patient and her mother were HLA-A24 and HLA-DR 4 with the subtype HLA-DRB1*0408. Based on clinical symptoms and the HLA pattern, the diagnosis of actinic prurigo was made. Treatment with thalidomide led to resolution of the disease. This case report of a Caucasian woman suffering from a hereditary form of actinic prurigo questions the established classification of actinic prurigo into a hereditary Native American form and a sporadic form occurring in the non-Native American population.

Enhancement of cytokine production and AP-1 transcriptional activity in T cells by thalidomide-related immunomodulatory drugs.

CC-4047 (Actimid) and CC-5013 (Revimid) belong to a class of thalidomide analogs collectively known as the immunomodulatory drugs (IMiDs), which are currently being assessed in the treatment of patients with multiple myeloma and other cancers. IMiDs potently enhance T cell and natural killer cell responses and inhibit tumor necrosis factor-alpha, interleukin (IL)-1 beta, and IL-12 production from LPS-stimulated peripheral blood mononuclear cells. However, the molecular mechanism of action for these compounds is unknown. Herein, we report on the ability of the IMiDs to up-regulate production of IL-2 from activated human CD4+ and CD8+ peripheral blood T cells, production of IL-2 and IFN-gamma from T helper (Th)1-type cells, and production of IL-5 and IL-10 from Th2-type cells. Elevation of IL-2 production from Jurkat T cells was observed as early as 6 h poststimulation and correlated with an increase in IL-2 promoter activity that was dependent upon the proximal but not the distal AP-1 binding site. The IMiDs enhanced AP-1-driven transcriptional activity 2- to 4-fold after 6 h of T cell stimulation, and their relative potencies for AP-1 activation correlated with their potencies for increased IL-2 production in Jurkat T cells and in CD4+ or CD8+ human peripheral blood T cells. The most potent of these IMiDs, CC-4047, had no effect on nuclear factor of activated T cells transcriptional activity, calcium signaling, or phosphorylation of extracellular signal-regulated kinase 1/2, c-Jun NH2-terminal kinase 1/2, p38 mitogen-activated protein kinase, or c-Jun/Jun D in Jurkat T cells. These data suggest that IMiDs increase T cell cytokine production by potentiating AP-1 transcriptional activity.

Thalidomide down-regulates transcript levels of GC-rich promoter genes in multiple myeloma.

Thalidomide (Thd), a potent teratogen, was shown to have therapeutic potential in cancer, primarily in multiple myeloma (MM), yet its mechanism of action has not been elucidated. It was recently suggested that its teratogenicity is derived from interference in expression of genes regulated by GC-rich promoters by blocking the binding of SP1 transcription factor to its motif. We explored the validation of the proposed model by focusing on potential molecular targets associated with MM pathogenesis. Cell lines RPMI 8226, U266, and ARH-77 were exposed for 24 h to racemic Thd and analyzed for apoptosis, membranal expression of CD29 and CD63, transcript level of hTERT, CD63, and IGFI-R (characterized by GC-rich motifs) and telomerase activity. Analysis of an hTERT core promoter reporter gene expression [enhanced green fluorescent protein (EGFP)] in transiently transfected RPMI 8226 incubated with racemic and steric (+/-)-enantiomers of Thd was performed. A consistent reduction ( approximately 10-40%) in transcript levels of all three assayed genes in all three cell lines was demonstrated in the presence of racemic Thd. Significant reduction of EGFP was demonstrated in cells transfected with hTERT reporter gene and treated with racemic and (S)-Thd. Our results show that Thd's antimyeloma activity can be ascribed to the same mechanism responsible for its teratogenic effect and that the inhibition of GC-rich promoter genes is mostly attributed to the S-racemate. Indeed, this selectivity delineates GC-rich promoter genes as a unique group eligible for specific drug targeting.

Thalidomide inhibits lipoarabinomannan-induced upregulation of human immunodeficiency virus expression.

Mycobacterium tuberculosis accelerates the progression of human immunodeficiency virus type 1 (HIV-1) infection. The results of this study, which show that thalidomide inhibits the upregulation of HIV-1 expression in U1 cells stimulated with mycobacterial lipoarabinomannans, support the rationale behind conducting controlled trials of this immunodeficiency agent with patients dually infected with HIV-1 and M. tuberculosis.

Thalidomide inhibits the growth and progression of hepatic epithelioid hemangioendothelioma.

Hepatic epithelioid hemangioendothelioma (HEH) is a rare vascular tumor of the liver with an unpredictable malignant potential. Its growth can lead to hepatic failure, extrahepatic metastasis and death. Surgical resection or liver transplantation is the treatment of choice if metastasis is not identified. Several antineoplastic agents have been proposed for cases of nonresectable HEH. We report the case of a 52-year-old patient with HEH metastatic to the lungs who was successfully treated with oral thalidomide therapy.

Scleromyxedema, a positive effect with thalidomide.

Scleromyxedema is a rare dermatological disorder marked by widespread symmetric 2- to 3-mm, firm, waxy, closely spaced papules involving the hands, forearms, face, neck, upper trunk and thighs. The most common extracutaneous manifestation of scleromyxedema is a benign plasma cell dyscrasia. Treatment of scleromyxedema is limited by the lack of long-term results, toxicity and significant adverse side effects. We report a severe case of scleromyxedema who had marked improvement when treated with thalidomide.

Shoulder joint replacement for osteoarthrosis in association with thalidomide-induced phocomelia.

The natural history of thalidomide-induced phocomelia has not yet been established since only 35 years have elapsed since the problems associated with this drug became evident. This paper presents what is considered to be the first case of osteoarthrosis in such an individual treated by shoulder joint replacement. Joint arthoplasty is almost certainly going to become an integral part of the life-long rehabilitation process in such affected individuals.

A phase 2 trial of combination low-dose thalidomide and prednisone for the treatment of myelofibrosis with myeloid metaplasia.

Single-agent thalidomide (THAL) at "conventional" doses (> 100 mg/d) has been evaluated in myelofibrosis with myeloid metaplasia (MMM) based on its antiangiogenic properties and the prominent neoangiogenesis that occurs in MMM. THAL monotherapy at such doses produces approximately a 20% response rate in anemia but is poorly tolerated (an adverse dropout rate of > 50% in 3 months). To improve efficacy and tolerability, we prospectively treated 21 symptomatic patients (hemoglobin level < 10 g/dL or symptomatic splenomegaly) with MMM with low-dose THAL (50 mg/d) along with a 3-month oral prednisone (PRED) taper (beginning at 0.5 mg/kg/d). THAL-PRED was well tolerated in all enrolled patients, with 20 patients (95%) able to complete 3 months of treatment. An objective clinical response was demonstrated in 13 (62%) patients, all improvements in anemia. Among 10 patients who were dependent on erythrocyte transfusions, 7 (70%) improved and 4 (40%) became transfusion independent. Among 8 patients with thrombocytopenia (platelet count < 100 x 10(9)/L), 6 (75%) experienced a 50% or higher increase in their platelet count. In 4 of 21 patients (19%), spleen size decreased by more than 50%. Responses observed were mostly durable after discontinuation of the PRED. The dose of THAL in this study (50 mg/d) was better tolerated than the higher doses used in previous studies. Adverse events associated with corticosteroid therapy were mild and transient. Clinical responses did not correlate with improvements in either intramedullary fibrosis or angiogenesis. THAL-PRED is well tolerated and preliminarily appears to be a promising drug regimen for treating cytopenias in patients with MMM.

Superiority of thalidomide and dexamethasone over vincristine-doxorubicindexamethasone (VAD) as primary therapy in preparation for autologous transplantation for multiple myeloma.

The aim of the present study was to compare thalidomide-dexamethasone (Thal-Dex) and vincristine-doxorubicin-dexamethasone (VAD) as primary therapy in preparation for autologous peripheral blood stem-cell (PBSC) transplantation for multiple myeloma (MM). For this purpose, we performed a retrospective matched case-control analysis of 200 patients who entered 2 consecutive studies from 1996 to 2004 and received Thal-Dex (n = 100) or VAD (n = 100) administered for 4 months before collection of PBSCs and autologous transplantation. Matching criteria included age, clinical stage, and serum beta2-microglobulin levels. In comparison with VAD, Thal-Dex resulted in a significantly higher response rate (52% versus 76%, respectively; P < .001) and effected more profound reduction in myeloma cell mass of both immunoglobulin G (IgG; P = .02) and IgA (P = .03) type. More frequent toxicities included nonfatal deep vein thrombosis with Thal-Dex (15%) and granulocytopenia with VAD (12%). In each of the 2 treatment groups, 91% of patients proceeded to PBSC mobilization. The median number of collected CD34+ cells was 7.85 x 10(6)/kg in the Thal-Dex group and 10.5 x 10(6)/kg in the control group. Thal-Dex may be considered an effective and relatively well-tolerated oral alternative to the more complex VAD regimen as front-line therapy for MM patients who are candidates for subsequent autologous transplantation.
