Presentation includes discussion of the following off-label use of a
drug: Lenalidomide in multiple myeloma


Bortezomib
Potent preclinical activity against multiple myeloma (MM) via
inhibition of NF-B, activation of caspases 3, 8, 91
Maximum tolerated dose (MTD) 1.3 mg/m2 twice wkly for 2 wks
followed by 1 wk of rest 2-4
Efficacious in phase 2 trials of relapsed and/or refractory MM:
SUMMIT,5 CREST6
Pivotal phase 3 randomized trial (APEX,7 n = 669)

­ Significant improvements in response rate (RR), time to
progression (TTP), survival compared with high-dose
dexamethasone (dex) in relapsed MM pts with 1­3 prior
therapies

In frontline trials in MM, RR 75%­95%, complete response
(CR)/near CR (nCR) 25%­31%8-10

Lenalidomide
Potent preclinical activity against MM via caspase 8-dependent
apoptosis; T cell proliferation/stimulation, IL-2, IFN-
production;
TNF
& IL-1 inhibition1-4
Active, well tolerated in MM: responses with 50% M-protein
reduction in

­ 24%­40% of pts receiving lenalidomide ± dex, with relapsed and
relapsed/refractory MM, including prior thal and bortezomib5-7
2 pivotal phase 3 randomized trials with HD dex (MM-009, n=354,
010, n=351)

­ Significant improvement in RR (CR, PR),TTP vs HD dex alone in
relapsed MM pts with 1-3 prior therapies 8
In frontline with high dose dex, RR 91%, CR / nCR 38%9

Rationale
Lenalidomide sensitizes MM cells to bortezomib and
dex in preclinical studies1
Expected overlapping toxicities manageable
(primarily hematologic)2
In phase 1

­ MTD of lenalidomide 25 mg (PO daily, 28-day
cycle)2,3
­ MTD of bortezomib 1.3 mg/m2 (IV twice weekly,
21-day cycle)4-6

­ Identify MTD and recommended dose for phase 2
study
Secondary
­ Evaluate response
­ Assess PK
­ Explore pharmacogenomics/surrogate markers

Summary
Combination of lenalidomide and bortezomib well tolerated
­ One DLT in cohort 4, cohort 6
­ No DVT
­ No significant PN or fatigue
Active in heavily pretreated pts, including pts who received
either agent alone

­ 67% RR (CR + nCR + PR + MR)
­ Dex added in 3 pts ­ no added toxicity; PD in 1 pt, SD in
2 pts
Study ongoing to determine MTD
­ Additional 10 pts to be enrolled at MTD

Future Directions
Completion of PK, surrogate marker analysis
Phase 2 studies in relapsed and relapsed
refractory MM
Phase 2 study in newly diagnosed pts
"Steroid sparing" approach (lower dose dex)
Potential oral/IV regimens using lenalidomide
and bortezomib in combination with other
novel agents
