50 patients with relapsed or refractory myeloma were treated with thalidomide, at escalating doses 100-800 mg PO qhs. Results:
  - Response rate was 44%, when including both PR (45.5%) and minor response (54.5%). No CR were seen.
  - The median tolerated dose of thalidomide was 400 mg, and only 2 patients (4%) were able to tolerate 800 mg daily
  - The median time to response was 29 days (range, 8-155 days)
Interestingly, leukopenia was a clinical predictor of response to thalidomide: 18 of the 22 (82%) responders had  a transient reduction of WBC before the the response, whereas this was seen in only 4 of the 28 (14%) non-responders (p<0.001). Leukopenia was generally transient, and it quickly resolved despite the continuation of thalidomide.

Among 256 newly diagnosed myeloma patients randomized to thalidomide vs no thalidomide, DVT was observed more frequently in the thalidomide group (hazard ratio: 4.5). Low dose coumadin (1 mg/day) did not prevent venous thromboembolism, whereas LMWH (enoxaparin 40 mg SC qd) effectively prevented it.

Prophylactic low-dose aspirin is effective antithrombotic therapy for combination treatments of thalidomide or lenalidomide in myeloma.

In this study, the prophylactic use of low-dose aspirin (81 mg) was effective in reducing the incidence of venous thromboembolism in patients with multiple myeloma treated with thalidomide or lenalidomide.

Aspirin, Warfarin, or Enoxaparin Thromboprophylaxis in Patients With Multiple Myeloma Treated With Thalidomide: A Phase III, Open-Label, Randomized Trial.

Palumbo A, Cavo M, Bringhen S, Zamagni E, Romano A, Patriarca F, Rossi D, Gentilini F, Crippa C, Galli M, Nozzoli C, Ria R, Marasca R, Montefusco V, Baldini L, Elice F, Callea V, Pulini S, Carella AM, Zambello R, Benevolo G, Magarotto V, Tacchetti P, Pescosta N, Cellini C, Polloni C, Evangelista A, Caravita T, Morabito F, Offidani M, Tosi P, Boccadoro M.
In this study, 667 patients with myeloma treated with thalidomide were randomized into 3 groups:
  - Aspirin 100 mg/day PO
  - Warfarin fixed low-dose, 1.25 mg/day PO
  - LMWH: enoxaparin 40 mg/day SC
Treatment was continued for the first 3-6 cycles of induction therapy. Both aspirin and fixed low-dose warfarin showed similar efficacy in reducing thromboembolic complications when compared with LMWH. Rate of complications (i.e., DVT, PE, arterial thrombosis, acute cardiovascular events, and sudden death) was:
  - 5% with LMWH
  - 6% with aspirin
  - 8% with warfarin



Thalidomide neuropathy: clinical, electrophysiological and neuroradiological features.

Isoardo G, Bergui M, Durelli L, Barbero P, Boccadoro M, Bertola A, Ciaramitaro P, Palumbo A, Bergamasco B, Cocito D.
The authors obtained nerve conduction studies, somatosensory-evoked potentials, and MRI of cervical and dorsal spinal cord MRI in 6 patients with myeloma and thalidomide-induced polyneuropathy. The results indicated that thalidomide induces an axonal length-dependent sensory neuropathy and, less frequently, a ganglionopathy.

40 myeloma patients treated with thalidomide for longer than 12 months were assessed for neurotoxicity. Neurotoxicity was the most important and frequent (75%) toxicity of thalidomide. Symptoms included paresthesias, tremors, and dizziness.
  - Grade 1: 15%
  - Grade 2: 32.5%
  - Grade 3: 27.5% (patients with grade 3 neurotoxicity had to interrupt the therapy)
EMG showed a symmetrical, mainly sensory peripheral neuropathy.

This is a report of the dermatologic side effects of thalidomide in 87 patients with multiple myeloma enrolled in a clinical trial with thalidomide either alone or in combination with dexamethasone. The prevalence of skin rash with thalidomide was high, because a minor-moderate skin rash was observed in 46% of patients (43% in patients taking thalidomide + dexamethasone). 3 patients taking thalidomide + dexamethasone developed a severe skin rash that required hospitalization and discontinuation of thalidomide.
