BORTEZOMIB DR. REDDYS

Bortezomib treatment must be initiated under supervision of a physician experienced in the treatment of cancer patients, however Bortezomib may be administered by a healthcare professional experienced in use of chemotherapeutic agents.

6). 3 mg/m² body surface area twice weekly for two weeks on days 1, 4, 8, and 11 in a 21-day treatment cycle. This 3-week period is considered a treatment cycle. It is recommended that patients receive 2 cycles of bortezomib following a confirmation of a complete response.

It is also recommended that responding patients who do not achieve a complete remission receive a total of 8 cycles of bortezomib therapy. At least 72 hours should elapse between consecutive doses of bortezomib. 4). 7 mg/m²). If the toxicity is not resolved or if it recurs at the lowest dose, discontinuation of bortezomib must be considered unless the benefit of treatment clearly outweighs the risk.

4). Patients with pre-existing severe neuropathy may be treated with bortezomib only after careful risk/benefit assessment. 3 mg/m² once per week Grade 2 with pain or Grade 3 (severe symptoms; limiting self care ADL***) Withhold bortezomib treatment until symptoms of toxicity have resolved.

7 mg/m² once per week. Grade 4 (life-threatening consequences; urgent intervention indicated) and/or severe autonomic neuropathy Discontinue bortezomib * Based on posology modifications in Phase II and III multiple myeloma studies and post-marketing experience.

0. ** Instrumental ADL: refers to preparing meals, shopping for groceries or clothes, using telephone, managing money, etc; *** Self care ADL: refers to bathing, dressing and undressing, feeding self, using the toilet, taking medicinal products, and not bedridden.

3 mg/m² body surface area twice weekly for two weeks on days 1, 4, 8, and 11 in a 21-day treatment cycle. This 3-week period is considered a treatment cycle. At least 72 hours should elapse between consecutive doses of bortezomib. Pegylated liposomal doxorubicin is administered at 30 mg/m² on day 4 of the bortezomib treatment cycle as a 1 hour intravenous infusion administered after the bortezomib injection.

Up to 8 cycles of this combination therapy can be administered as long as patients have not progressed and tolerate treatment. Patients achieving a complete response can continue treatment for at least 2 cycles after the first evidence of complete response, even if this requires treatment for more than 8 cycles.

Summary of the safety profile Serious adverse reactions uncommonly reported during treatment with bortezomib include cardiac failure, tumour lysis syndrome, pulmonary hypertension, posterior reversible encephalopathy syndrome, acute diffuse infiltrative pulmonary disorders and rarely autonomic neuropathy.

The most commonly reported adverse reactions during treatment with bortezomib are nausea, diarrhoea, constipation, vomiting, fatigue, pyrexia, thrombocytopenia, anaemia, neutropenia, peripheral neuropathy (including sensory), headache, paraesthesia, decreased appetite, dyspnoea, rash, herpes zoster and myalgia.

Tabulated summary of adverse reactions Multiple Myeloma Undesirable effects in Table 7 were considered by the investigators to have at least a possible or probable causal relationship to bortezomib. 3 mg/m² and included in Table 7. Overall, bortezomib was administered for the treatment of multiple myeloma in 3,974 patients.

Adverse reactions are listed below by system organ class and frequency grouping.

Frequencies are defined as:

Very common (≥ 1/10); common (≥ 1/100 to < 1/10); uncommon (≥ 1/1,000 to < 1/100); rare (≥ 1/10,000 to < 1/1,000); very rare (< 1/10,000), not known (cannot be estimated from the available data). Within each frequency grouping, undesirable effects are presented in order of decreasing seriousness.

When bortezomib is given in combination with other medicinal products, the Summary of Product Characteristics of these other medicinal products must be consulted prior to initiation of treatment with bortezomib. 6). Intrathecal administration There have been fatal cases of inadvertent intrathecal administration of bortezomib.

5 mg powder for solution for injection is for intravenous or subcutaneous use. Bortezomib should not be administered intrathecally. Gastrointestinal toxicity Gastrointestinal toxicity, including nausea, diarrhoea, vomiting and constipation are very common with bortezomib treatment.

8). Therefore, patients who experience constipation should be closely monitored. Haematological toxicity Bortezomib treatment is very commonly associated with haematological toxicities (thrombocytopenia, neutropenia and anaemia). In studies in patients with relapsed multiple myeloma treated with bortezomib and in patients with previously untreated MCL treated with bortezomib in combination with rituximab, cyclophosphamide, doxorubicin, and prednisone (BzR-CAP), one of the most common haematologic toxicity was transient thrombocytopenia.

Platelets were lowest at day 11 of each cycle of bortezomib treatment and typically recovered to baseline by the next cycle. There was no evidence of cumulative thrombocytopenia.. The mean platelet count nadir measured was approximately 40% of baseline in the single-agent multiple myeloma studies and 50%in the MCL study.

In patients with advanced myeloma the severity of thrombocytopenia was related to pre-treatment platelet count: for baseline platelet counts < 75,000/
l, 90% of 21 patients had a count ≤ 25,000/
l during the study, including 14% < 10,000/
l; in contrast, with a baseline platelet count > 75,000/
l, only 14% of 309 patients had a count ≤ 25,000/μl during the study.

8%) of Grade ≥ 3 thrombocytopenia in the bortezomib treatment group (BzR-CAP) as compared to the non- bortezomib treatment group (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone [R- CHOP]). 2%]). 9% of patients in the R-CHOP group.
