Side effects of Zegomib 3.5 mg in details

infoA side effect of any drug can be defined as the unwanted or undesired effect produced by the drug. The side effect can be major or in few medications minor that can be ignored. Side effects not only vary from drug to drug, but it also depends on the dose of the drug, the individual sensitivity of the person, brand or company which manufactures it. If side effects overweigh the actual effect of the medicine, it may be difficult to convince the patient to take the drug. Few patients get specific side effects to specific drugs; in that case, a doctor replaces the drug with another. If you feel any side effect and it troubles you, do not forget to share with your healthcare practitioner.

Summary of Clinical Trials of Zegomib 3.5 mg IV in Patients with Relapsed/Refractory Multiple Myeloma: The safety and efficacy of Zegomib 3.5 mg were evaluated in 3 studies at the recommended dose of 1.3 mg/m2. These included a phase 3 randomized, comparative study versus dexamethasone of 669 patients with relapsed or refractory multiple myeloma who had received 1-3 prior lines of therapy (M34101-039); a phase 2 single arm, open-label, multicenter study of 202 patients who had received at least 2 prior therapies and demonstrated disease progression on their most recent therapy (M34100-025); and a phase 2 dose-response clinical study in relapsed multiple myeloma for patients who had progressed or relapsed on or after 1st line therapy with Zegomib 3.5 mg 1 mg/m2 or 1.3 mg/m2 (M34100-024).

Summary of Clinical Trials of Zegomib 3.5 mg IV versus SC in Patients with Relapsed Multiple Myeloma: The safety and efficacy of Zegomib 3.5 mg SC were evaluated in 1 phase 3 study at the recommended dose of 1.3 mg/m2. This was a randomized, comparative study of Zegomib 3.5 mg IV versus SC in 222 patients with relapsed multiple myeloma.

Although in general, safety data were similar for the IV and SC treatment groups, the following table highlights differences larger than 10% in the overall incidence of adverse drug reactions between the 2 treatment arms.

Patients who received Zegomib 3.5 mg SC compared to IV administration had 13% lower overall incidence of treatment-emergent adverse drug reactions that were grade 3 or higher in toxicity (57% vs 70%, respectively) and a 5% lower incidence of discontinuation of Zegomib 3.5 mg (22% vs 27%). The overall incidence of diarrhea (24% for the SC arm vs 36% for the IV arm), gastrointestinal and abdominal pain (6% for the SC arm vs 19% for the IV arm), asthenic conditions (27% for SC arm vs 39% for IV arm), upper respiratory tract infections (14% SC arm vs 26% IV arm) and peripheral neuropathy NEC (38% SC arm vs 53% IV arm) were 12-15% lower in the SC group than the IV group. In addition, the incidence of peripheral neuropathies that were grade ≥3 in toxicity was 10% lower (6% for SC vs 16% for IV) and the discontinuation rate due to peripheral neuropathies was 8% lower for the SC group (5%) as compared to the IV group (12%).

Six percent (6%) of patients were reported to have had an adverse local reaction to SC administration, mostly redness. Only 2 (1%) subjects were reported as having severe reactions. These severe local reactions were 1 case of pruritus and 1 case of redness. These reactions seldom led to dose modifications and all resolved in a median of 6 days.

Summary of Clinical Trials in Patients with Previously Untreated Multiple Myeloma: Table 19 describes safety data from 340 patients with previously untreated multiple myeloma who received Zegomib 3.5 mg IV (1.3 mg/m2) in combination with melphalan (9 mg/m2) and prednisone (60 mg/m2) in a prospective phase 3 study.

Herpes Zoster Virus Reactivation: Physicians should consider using antiviral prophylaxis in patients being treated with Zegomib 3.5 mg. In the phase 3 study in patients with previously untreated multiple myeloma, the overall incidence of herpes zoster reactivation was more common in patients treated with VcMP compared with MP (14% vs 4%, respectively). Antiviral prophylaxis was administered to 26% of the patients in the VcMP arm. The incidence of herpes zoster among patients in the VcMP treatment group was 17% for patients not administered antiviral prophylaxis compared to 3% for patients administered antiviral prophylaxis.

Patients with Mantle Cell Lymphoma: Safety data for patients with mantle cell lymphoma were evaluated in a phase 2 study, which included 155 patients treated with Zegomib 3.5 mg at the recommended dose of 1.3 mg/m2. The safety profile of Zegomib 3.5 mg in these patients was similar to that observed in patients with multiple myeloma. Notable differences between the 2 patient populations were that thrombocytopenia, neutropenia, anemia, nausea, vomiting and pyrexia were reported more often in the patients with multiple myeloma than in those with mantle cell lymphoma; whereas peripheral neuropathy, rash and pruritis were higher among patients with mantle cell lymphoma compared to patients with multiple myeloma.
