Thalidomide has been reported to be an effective agent for treatment of chronic graft-versus-host disease (CGVHD). To determine the efficacy of this agent in patients with refractory CGVHD a total of 80 patients who failed to respond to prednisone (PSE) or PSE and cyclosporine (CSA) were treated with thalidomide. Sixteen patients (20%) had a sustained response, 9 with a complete remission and 7 with a partial response. Twenty-nine patients (36%) had thalidomide discontinued because of side effects, which included sedation, constipation, neuritis, skin rash, and neutropenia. Side effects were reversible with drug discontinuation except for mild residual neuritis in one case. Rashes and neutropenia have not previously been reported as thalidomide side effects when used for CGVHD treatment. We conclude thalidomide is immunosuppressive and active in the treatment of CGVHD. A high incidence of reversible side effects limited dose intensity and reduced the number of patients who could benefit from treatment.

A 52-year-old dentist with kappa light chain multiple myeloma relapsed 6 months after 180 mg/m2 melphalan and an autograft. A partial remission had been attained after the autograft. Relapse occurred while he was on dexamethasone maintenance therapy. Chemotherapy was not an option due to low blood counts. Thalidomide was administered at relatively high doses (escalated up to 700 mg daily and continued for 4 months). There was a prompt decline in urine protein from 6067 mg/day to 2177 mg/day within a month. The response continued to improve with achievement of near-complete remission within 6 months and a decline in urine protein to 413 mg/day. Subsequently, grade 3 neutropenia and peripheral neuropathy required dose reduction to 200 mg/day. Disease activity parameters continued to improve on the lower dose of thalidomide. Nine months after starting thalidomide, the patient is in near-complete remission, enjoys an excellent quality of life, and has returned to work. We conclude that thalidomide can effectively control myeloma relapsing after high-dose chemotherapy, and may be especially useful in resistant cases or those unable to tolerate further chemotherapy.

A multicenter, double-blind, randomized, placebo-controlled study was conducted to determine the safety and efficacy of thalidomide in reduced, intermittent doses for preventing recurrences of oral and esophageal aphthous ulcers in patients with human immunodeficiency virus (HIV) infection. Forty-nine HIV-infected patients whose ulcers previously had healed as a result of thalidomide therapy were randomly assigned to receive either 100 mg of oral thalidomide or placebo 3 times per week for 6 months. Ulcers recurred in 14 (61%) of 23 thalidomide-randomized patients, compared with 11 (42%) of 26 placebo-randomized patients, with no significant difference in the median time to recurrence of ulcers (P=.221). There were no changes in plasma levels of HIV RNA, tumor necrosis factor (TNF)-alpha, and soluble TNF receptor II at the time of ulcer recurrence. Adverse events among patients treated with thalidomide included neutropenia (5 patients), rash (5 patients), and peripheral sensory neuropathy (3 patients). Thalidomide in lower intermittent doses is ineffective at preventing recurrence of aphthous ulcers in HIV-infected persons.

Thalidomide shows a significant ability to eliminate painful mouth ulcers in HIV patients and is also effective in reversing wasting and clearing up severe diarrhea caused by microsporidiosis. However, the drug comes with several side effects. Side effects include peripheral neuropathy, neutropenia, sedation, rash, and a small but statistically significant rise in HIV viral loads. Many physicians are not using Thalidomide due to the publicity that was generated from the birth defects that it caused. Thalidomide is available free through a compassionate use program and through an Investigational New Drug (IND) protocol. Contact information is included for both of these programs.

We conducted a clinical trial of thalidomide as initial therapy for asymptomatic smoldering (SMM) or indolent multiple myeloma (IMM). Sixteen patients were studied. Thalidomide was given orally at a dose of 200 mg/day for 2 weeks, and then increased as tolerated by 200 mg/day every 2 weeks to a maximum dose of 800 mg/day. Bone marrow microvessel density (MVD) and angiogenesis grading were estimated using CD34 immunostaining. Six patients had a confirmed response to therapy with at least 50% or greater reduction in serum and urine monoclonal (M) protein. When minor responses (25-49%) decrease in M protein concentration) were included, 11 of 16 patients (69%) responded to therapy. Major grade 3-4 toxicities included two patients with somnolence, and one patient each with syncope and neutropenia. Pre-treatment MVD was not a significant predictor of response to therapy, median MVD 4 and 12 in responders and non-responders respectively, P = 0.09. We conclude that thalidomide has significant activity in the treatment of newly diagnosed SMM/IMM. However, we do not recommend treatment with thalidomide at this stage since some patients with SMM/IMM can be stable for several months or years without any therapy. Additional randomized trials are needed to determine if thalidomide will delay progression to active multiple myeloma.

Neo-adjuvant chemotherapy of epirubicin plus paclitaxel was administered to 23 patients with locally advanced breast cancer (including 13 cases of stage IIb, 6 of stage IIIa, and 4 of stage IIIb). All patients were female. They were treated with epirubicin 60 mg/m2, on day 1, by i.v. followed paclitaxel 150 mg/m2 by 3 hours continuous infusion on day 2 and every 3 weeks repeatedly. Premedication with dexamethasone, ondansetron, diphenhydramine and cimetidine were administered to prevent gastroenteric and allergic reactions before chemotherapy. Two to 4 cycles were used. Ten out of 23 patients had a complete response, 10 had partial response, and 3 had no change. The response rate was 87% (20/23). Six out of 23 patients underwent breast conserving surgery as tumor size had become smaller and downstaging was realized after neo-adjuvant chemotherapy. The major toxicities included neutropenia, myalgia, arthralgia, nephrotoxicity, gastroenteric reactions, alopecia and flushing to the face. However, these were well tolerated in these patients.

Thalidomide as a single agent (200-400 mg/day) was administered in fourteen cases of refractory myeloma, from March 2001 till February 2002. The median age was 71 years (range 58 to 85 years), and the efficacy of thalidomide was observed in cases receiving treatment for at least three consecutive months. Response was evaluated in February 2002, according to the criteria for assessment of response described by Kakimoto et al. At the time of evaluation, two cases were in the PR2 state, one in PR3, two were stable, and three were PD. Evaluation of the response was not possible in six cases in whom treatment had to be discontinued due to intolerable side effects. The response to thalidomide was variable, with some cases responding well even to a low dose (200 mg/day) while a few others showed an early relapse due to the refractory nature of the disease in its response to the drug. The efficacy of treatment seemed to be correlated with the maturation pattern of myeloma cells. Side effects included neurological complications like somnolence, physiological symptoms such as constipation and so on, etc but all were relieved with symptomatic treatment. The drug was well tolerated in geriatric patients. Neutropenia was a dose limiting factor with half of the cases (7/14) presenting with severe neutropenia (grade 3-4), but a response was observed in all of them on administration of G-CSF. Thromboembolism occurred in two cases, the cause of which is not clear. These results suggest that thalidomide is a well tolerated drug and can be considered as a mainstay in the therapy of refractory myeloma.

Thalidomide, an antiemetic administered in 60th of the 20th century to pregnant women, has become notorious for a range of adverse effects which led to its taking off market. In recent years, its antimyeloma effect was discovered. The aim of the work was to evaluate the incidence of adverse reactions to thalidomide. Its therapeutic effect has not been assessed because of a short period of monitoring and diversity of a sample. The assessed sample consisted of 17 patients with diagnosis of multiple myeloma (10 men and 7 women). An average age of patients was 62.9 +/- 9.4. An average time elapsed from making the diagnosis to starting the treatment with thalidomide was 51.0 +/- 23.7 months. An average length of therapy was 20.1 +/- 9.6 weeks. An average daily maximum therapeutic dose was 138.3 +/- 83.2 mg. Data were collected from outpatient physicians reports, regular laboratory tests, and direct interviews with patients. To classify severity of adverse drug effects (grades 0-4) we used WHO criteria, Cancer and Leukemia Group B criteria, and in cases where certain adverse effects were not included in the above mentioned criteria, we defined our own criteria. The most frequent adverse effects included: leucopenia or neutropenia in 12 (70.6%) patients, altered state of consciousness in 11 (64.7%) patients, obstipation in 10 (58.8%) patients, skin alterations in 9 (52.9%) patients, dizziness in 8 (47.1%) patients, peripheral neuropathy in 7 (41.2%) patients, spasms and spasmodic convulsions in 7 (41.2%) patients, and altered liver tests in 6 (35.3%) patients. From the perspective of necessity to interrupt treatment or reduce the dose the most severe disorders included: peripheral neuropathy in 2 patients (inability to control lower extremities), altered consciousness in 1 patient (protracted somnolence during a day), skin alteration in 1 patient (generalized toxoalergic reaction), leucopenia or neutropenia in 1 patient (1.0 resp < 0.5 x 10(9)/l), altered vision in 1 patient (blurred vision), hypothyroidism in 1 patient, and altered mood in 1 patient (subjective feeling of depression). This work proved thalidomide to be beneficial for the patients with multiple myeloma but it also shoved necessity to intensively monitor its adverse effects and to adjust its doses.

Thalidomide has shown promise in the treatment of newly diagnosed multiple myeloma and relapsed/refractory disease, but side effects such as somnolence, constipation, and neuropathy limit its use. CC-5013, an immunomodulatory drug (IMiD), is more potent than thalidomide. CC-5013 has various immunomodulatory effects, including growth arrest or apoptosis of drug-resistant myeloma cell lines and inhibition of binding of myeloma cells to bone marrow stromal cells. Clinically, 17 of 24 patients (71%) with relapsed/refractory disease experienced a reduction of paraprotein of > or = 25% following treatment with CC-5013, including 11 who had a history of treatment with thalidomide. Another two experienced stable disease. Median time to best response was 2 months (range, 1 to 11) and median duration was 6 months (range, 2 to 18). Grade 3 thrombocytopenia was seen in 20% of patients; grade 3 neutropenia was seen in 60%; and grade 4 neutropenia was seen in 16%. CC-5013 use was not associated with somnolence, constipation, or neuropathy. This article reviews thalidomide in multiple myeloma, the effects of thalidomide analogues IMiDs, and the preclinical and clinical data on CC-5013 in relapsed/refractory multiple myeloma.

Childhood tuberculous meningitis is associated with serious long-term sequelae, including mental retardation, behavior disturbances, and motor handicap. Brain damage in tuberculous meningitis results from a cytokine-mediated inflammatory response, which causes vasculitis and obstructive hydrocephalus. Thalidomide, a potent tumor necrosis factor alpha inhibitor, was well tolerated and possibly showed some clinical benefit in children with tuberculous meningitis during a pilot study. The purpose of the present study was to assess the effect of adjunctive thalidomide in addition to standard antituberculosis and corticosteroid therapy on the outcome of tuberculous meningitis. Thalidomide (24 mg/kg/day orally) or placebo was administered in a double-blind randomized fashion for 1 month to patients with stage 2 or 3 tuberculous meningitis. The study was terminated early because all adverse events and deaths occurred in one arm of the study (thalidomide group). Thirty of the 47 children enrolled received adjunctive thalidomide, of whom 6 (20%) developed a skin rash, 8 (26%) hepatitis, and 2 (6%) neutropenia or thrombocytopenia. Four deaths (13%) occurred in patients with very severe neurologic compromise at baseline; two deaths were associated with a rash. Motor outcome after 6 months of antituberculosis therapy was similar in the two groups, even though the thalidomide group showed greater neurologic compromise on admission. In addition, the mean IQ of the two treatment groups did not differ significantly (mean IQ thalidomide group 57.8 versus mean IQ control group 67.5; P = .16). These results do not support the use of adjunctive high-dose thalidomide therapy in the treatment of tuberculous meningitis.
