EMERGING VELCADE® RETREATMENT DATA
VELCADE is indicated for the treatment of patients with multiple myeloma who have received at least one prior therapy.
39% Overall Response Rate (ORR) with Velcade Retreatment +/- Dexamethasone7
|
|
Open-label, prospective, multicenter, single-arm US study (n=28
evaluable for safety; n=23 evaluable for response)*
|
–
|
Standard VELCADE dosing†
|
|
–
|
68% of patients had dexamethasone
|
|
–
|
Median number of prior therapies: 3 (including initial VELCADE)
|
|
–
|
ORR defined as ≥ 50% M-protein reduction
|
|
|
|
Time from initial first dose to progression following retreatment: 32 months‡
|
–
|
Median duration of VELCADE treatment in total: 6.4 months, 2.9 months initially and 2.8 months upon retreatment
|
|
–
|
Median time off treatment: 11.1 months (range: 2.4-33.9 months)
|
|
|
|
VELCADE was generally well-tolerated
|
–
|
5 patients (18%) experienced new peripheral neuropathy (PN),
2 (7%) had worsening PN during retreatment
|
|
–
|
2 serious adverse events (SAEs) were possibly related to VELCADE:
one grade 2 and one grade 3 thrombocytopenia
|
|
–
|
In total 11 patients reported SAEs
|
|
–
|
3 patients died: 2 due to disease progression, 1 due to sepsis
|
|
*The primary objective of the study was to determine ORR to VELCADE in patients who had achieved a response to prior VELCADE therapy with a duration of response > 4 months, at least 2 months of which they were off all therapy.
†VELCADE 1.3 mg/m2 days 1, 4, 8, and 11 of a 21-day cycle.
‡Relapsed patients were retreated at the VELCADE dose at which they finished their initial treatment administered as a bolus injection on days 1, 4, 8, and 11 of a 21-day cycle, alone or in combination with dexamethasone at the discretion of the investigator.
31% Retreatment Response Rate in Patients with Partial Response§ to Initial Velcade8
|
|
Retrospective, case series of 95 patients receiving 2 courses of VELCADE > 60 days apart in community centers
|
–
|
Median number of therapies prior to initial VELCADE: 3
|
|
–
|
Patients received a median of 4 cycles on initial VELCADE; 3 cycles
on retreatment
|
|
–
|
Median time between first and second VELCADE treatment: 5 months; 45% had intervening treatment
|
|
–
|
54% of patients had single-agent VELCADE followed by retreatment with single-agent VELCADE
|
|
|
|
38 patients responded to initial treatment, of whom 12 (31%) responded to retreatment¶
|
–
|
Of the 24 patients who did not respond to initial treatment (less than 50%
M-protein reduction), 3 (13%) responded to retreatment
|
|
|
|
Retreatment was not associated with unexpected toxicities
|
–
|
Discontinuation for toxicity decreased between initial and retreatment (from 39% to 27%)
|
–
|
Most common toxicities leading to discontinuation: neuropathy and thrombocytopenia
|
|
|
–
|
Discontinuation due to neuropathy decreased between initial and retreatment (from 17% to 5%)
|
|
§Partial response: 50%-90% reduction in M-protein values.
¶Sixty-two patients were evaluable for treatment response in both courses of therapy.
60% Overall Response Rate to Velcade® Retreatment
in Patients Who Responsded Initially
(≥50% M-Protein Reduction)9
|
|
Retrospective case series designed to clarify the utility of VELCADE retreatment in academic centers (n=22)
|
–
|
Patients received at least 2 cycles of VELCADE therapy with at
least a 60-day rest period prior to retreatment
|
|
–
|
Median number of therapies prior to retreatment: 6
|
|
–
|
VELCADE retreatment was typically given in combination (including dexamethasone, pegylated liposoneal doxorubicin, thalidomide, and melphalan)
|
|
|
|
Median time off treatment between end of initial VELCADE therapy and start of next alternative therapy: 12.6 months
|
–
|
Most patients (55%) had intervening treatment
|
|
–
|
Patients received initial treatment of 7.5 cycles of VELCADE and 5.5 cycles of retreatment
|
|
–
|
Patients who were sensitive to initial VELCADE treatment (≥50% M-protein reduction and TFI ≥6 months) were highly sensitive to VELCADE retreatment (75% ORR)
|
|
–
|
Response rates for patients who had not responded (less than 50%
M-protein reduction) to VELCADE initially was 29%
|
|
–
|
Response rates to retreatment were similar with combination
VELCADE use compared with single-agent VELCADE
|
|
|
|
No dose reductions for neuropathy upon retreatment (vs 4 during initial treatment)
|
–
|
2 patients withdrew due to toxicities during retreatment versus 3
during initial treatment
|
|
–
|
No hospitalizations for adverse events during retreatment (vs 3
during initial treatment)
