THE THRUST OF CURRENT DEVELOPMENTS

Identify subsets of patients with diffuse large B cell or Hodgkin lymphoma who are either destined to do well or fare poorly using techniques beyond the known clinical predictive factors, particuarly those techniques using molecular changes and/or PET scans.

By applying our better understanding of the (molecular) biology of these diseases, can we not only identify these subsets, but also develop and individualize treatments using less therapy for those with a good prognosis and using novel therapies for those destined to do poorly.

DHL: Impact of R-EPOCH

• Results of chi-square analysis

– Improved CR compared to R-CHOP (p = .005)

– Trend towards improvement w/ other regimens (p = .07)

– Decreased PD compared to R-CHOP (p = .005)

– Decreased PD w/ other intensive regimens (p = .003)

Page 22: LATEST CONCEPTS IN LARGE CELL AND HODGKIN LYMPHOMAS

DHL: Conclusions

• DHL has a poor prognosis, although a subset exists which can achieve durable CR

• R-EPOCH is associated with improved rates of CR and decreased rates of PD

• SCT does not clearly improve OS compared to observation alone in those achieving CR

• Novel approaches and agents are necessary to overcome unfavorable biology

Background

1Morgillo F, et al. Mol Cancer Ther 2008;7:1698-707; 2Dumstorf CA, et al. Mol Cancer Ther 2010;9:3158-63; 3Robertson MJ, et al. J Clin Oncol 2007;25:1741-6.

R-CHOP = rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone.

The PRELUDE Trial

• Patients with DLBCL and an IPI score of 3-5 at diagnosis who relapse after R-CHOP can have a poor prognosis.

• Enzastaurin is a potent and selective competitive inhibitor of PKCβ.1,2

• Enzastaurin was associated with freedom from progression in a phase II trial in a small subgroup of patients with relapsed or refractory DLBCL, thereby providing the rationale for this study.3

Page 25: LATEST CONCEPTS IN LARGE CELL AND HODGKIN LYMPHOMAS

Background

• PKCβ is the major isoform expressed in normal and malignant B cells.1,2

1Shipp MA, et al. Nat Med 2002;8:68-74; 2Graff JR, et al. Cancer Res 2005;65:7462-9; 3Robertson MJ, et al. J Clin Oncol 2007;25:1741-6.

• PKCβ is required for B cell receptor signaling, activation of NFκB, and VEGF-mediated angiogenesis.3

• Over-expression of PKCβ mRNA and protein is associated with a poor outcome in patients with DLBCL.1

DLBCL = diffuse large B cell lymphoma.

Discussion and Conclusions

• Enzastaurin did not improve DFS, EFS, or OS vs. placebo in patients with CR after initial treatment for DLBCL and an IPI score of ≥3

• Safety results of PRELUDE were consistent with the established safety profile of enzastaurin when used as a single-agent therapy in lymphoma and other cancers

• Cell-of-origin (GCB vs. non-GCB) was not prognostic for DFS in patients with CR

BENDAMUSTINE (with rituximab, vitamin R)

Three studies reported: Japan, NSH, Germany Doses of B were 120mgm/m2 days 1,2 + R

375 mgm/m2 every three weeks. German study was with unrx’ed elderly (E) Responses ranged from 58% to 69% (E) CR’s ranged from 19% to 54% (E) PFS/OS ranged from 6 to 7.7(E) months Significant toxicity

Page 30: LATEST CONCEPTS IN LARGE CELL AND HODGKIN LYMPHOMAS

Approach to “variant” DLBCLs GCB vs non-GCB

– R-CHOP is standard– Various randomized trials underway

MYC+, DH, TH– Consider FISH/IHC for MYC, BCL2, BCL6– Less favorable with R-CHOP– Unclear if other approaches better– Prospective studies underway, including R-EPOCH

Intensive BL type regimens

R-EPOCH

Less favorable outcome than other DLBCL with R-CHOP– Risk seems to be beyond age, IPI

Less favorable at progression

Rearrangements noted– BCL2 31%– BCL6 18%– C-MYC 13%

C-MYC worse PFS and OS

In Hodgkin lymphoma, what role do PET Scans play in lessening (toxicity) therapy and enhancing

cure?

May interim PET/CAT scans be of value or should scans be used only at the end of treatment?

75% PET-negative at central review after ABVD x 3

In the randomized PET-negative population, 3 yr PFS is 93.8% IFRT and 90.7% NFT

Risk difference -3% is within the maximum allowable difference of -7%

Radford J, et al. Blood. 2012;120: Abstract 547.

Page 40: LATEST CONCEPTS IN LARGE CELL AND HODGKIN LYMPHOMAS

Conclusion

Patients with a negative PET scan after 3 cycles ABVD have an excellent prognosis without further treatment, and for these patients RT can be avoided

Radford J, et al. Blood. 2012;120: Abstract 547.

Page 41: LATEST CONCEPTS IN LARGE CELL AND HODGKIN LYMPHOMAS

Commentary

These data are similar to those reported from Argentina several years ago.

Would the slightly higher rate of false negative PET scans at cycle 3 seen in those patients not receiving adjuvant radiotherapy been avoided had the PET been performed at cycle 2, or better yet, cycle 1

Response-adapted therapy based on quality- controlled/assured PET imaging may become the future standard of care in early-stage HL

Superior long-term overall survival with CMT is highly unlikely

Overall survival after treatment with Brentuximab

vedotin

• Median observation time from 1st dose: – All patients = 29.5 months

(range, 1.8 to 36.9) – CR patients = 29.1 months

(range, 2.6 to 34.3) • 60/102 patients (59%) remain

alive; median OS has not been reached (95% CI: 28.7, NE)

• Estimated 24-month survival rate* = 65% (95% CI: 55, 74)

Page 51: LATEST CONCEPTS IN LARGE CELL AND HODGKIN LYMPHOMAS

Overall Survival by Cycle 4 PET Status

Page 52: LATEST CONCEPTS IN LARGE CELL AND HODGKIN LYMPHOMAS

Conclusions

After a median observation time of ~2.5 years from first

brentuximab vedotin dose, 60 of 102 patients (59%) remain alive at

last follow up

Median OS has not yet been reached; the estimated 24-mo survival

rate was 65%

– Improved OS strongly correlated with both:

Achievement of CR Negative PET scan at Cycle 4

– Prolonged OS was observed in patients with both long and short progression-free intervals after auto-SCT

How can we improve the cure rate and reduce the toxicity for advanced stage disease?

• Response results at end of front-line therapy:

◦ AVD cohorts: 24 of 25 CR (96%)• In addition, 1 patient withdrew consent and 3

patients were lost to follow-up prior to completion of front-line therapy and were not evaluable for response

CONCLUSIONS

EFS (primary endpoint) is similar between treatment arms.

However, more progressions / relapses were observed with ABVD

while early discontinuations were more frequent with BEACOPP

In this high-risk group, conventional dose escalation with

BEACOPP 4+4 provides a better PFS compared to ABVD, yet not

good enough to improve OS

Additional considerations (treatment burden & cost, fertility issues,

risk of relapse, risk of salvage, immediate & late morbidities) may

guide physician / patient decisions toward ABVD or BEACOPP,

which currently may share the claim for “current standard of care”

CONCLUSIONS A GENERAL SURVEY OF STUDIES COMPARING BEACOPP TO

ABVD ALMOST ALL CONSISTENTLY SHOW A SUPERIOR

PROGRESSION FREE SURVIVAL FOR BEACOPP BUT LONG

TERM SURVIVAL SEEMS TO BE COMPARABLE DUE TO THE

TOXICITY OF BEACOPP.

AS WITH LIMITED STAGE DISEASE, CAN INTERIM PET SCANS

BE USED TO SELECT OUT THOSE PATIENTS NOTNEEDING

MORE AGGRESSIVE THERAPY AND THEREBY AVOID ALL THE

UNNECESSARY TOXICITY OF BEACOPP? IS GENETIC

INSTABILITY ADVANCED BY DR DIEHL TRULY OPERATIVE

EVEN AS EARLY AS (A PET SCAN AFTER) ONE CYCLE

Page 65: LATEST CONCEPTS IN LARGE CELL AND HODGKIN LYMPHOMAS

3 cycles of ABVD without IFRT has an excellent outcome for favorable stage IA/IIA

patients who are at the conclusion of treatment are PET neg.

Disease control may be slightly better for CMT as compared with CT (3%-7%),

although a survival difference is unlikely although long-term effects of IF (reduced)

RT are unknown.

BV + AVD results are comparable, if not superior, to ABVD for patients with stage

III/IV HL. Phase III comparison has opened. BV has been shown effective in

relapsing/refractory patients including those failing transplant. It is being

incorporated into many strategies for the rx of ‘difficult’ HL pts.

The overall results with ABVD are at least equal to BEACOPP with less toxicity.

Interim PET scans may prove valuable in the rx strategies for HL.
