Oncology 6-Part Case Series: Key Themes
• Mechanisms of action of novel agents and tissue
assays to predict response
• Side effects and toxicities of novel agents; dose
adjustments
• Assessment and management of adherence
• Specific goals of therapy and likely outcomes;
sequencing of agents in advanced disease
• Local and systemic complications of cancer: Fatigue,
pain, CNS involvement
• Care of older, frail patients and those with comorbidities
Oncology 6-Part Case Series: Key Themes
• Clinical trials as a means to access new treatments earlier
• Management of anxiety and depression
• Key determinants of patient satisfaction: What do people
with cancer want and need?
• Quality, value and cost: Investing resources optimally
• End-of-life care and planning
• Impact of the cancer experience on family and loved
ones, including minor children
• Impact of the oncology experience on oncology health
professionals

Case 1 (from the practice of Ms Goodrich)
• A 52-year-old man was diagnosed with Stage IVA MCL
in 2009
• He responded to R-CHOP and was considered for
autologous stem cell transplant (SCT), but his cardiac
ejection fraction was 41%
• Eighteen months later, disease progression occurred
• He received bendamustine/rituximab (BR) x 2 cycles,
then R-ICE x 3 followed by allogeneic SCT
• He then developed multiple subcutaneous relapses and
underwent treatment with rituximab/radiation therapy
and bortezomib/radiation therapy
• Most recently, treatment with ibrutinib has been initiated
• His wife, who sees the same medical oncologist, is
dying of metastatic endometrial cancer

FDA Approves the Use of Obinutuzumab in
Combination with Chlorambucil for CLL
“On November 1, 2013, the US Food and Drug
Administration (FDA) approved obinutuzumab (GA101)
for use in combination with chlorambucil for the
treatment of patients with previously untreated CLL,
based on demonstration of an improvement in PFS in a
randomized open-label multicenter trial that compared
obinutuzumab in combination with chlorambucil (GClb)
with chlorambucil (Clb) alone in patients with previously
untreated CD20-positive CLL.”

FDA Approves the Use of Ofatumumab in
Combination with Chlorambucil for CLL
“On April 17, 2014, the US Food and Drug Administration
(FDA) approved ofatumumab in combination with
chlorambucil, for the treatment of previously untreated
patients with CLL, for whom fludarabine-based therapy is
considered inappropriate, based on results from a Phase III
study (COMPLEMENT 1) which demonstrated statistically
significant improvement in median PFS in patients who
received the combination of ofatumumab and chlorambucil
compared to patients who received chlorambucil alone.”

Mechanism of Action of Idelalisib
Idelalisib
Adapted from Woyach JA et al. Blood 2012;120(6):1175-84.
• 220 patients with decreased renal function, previous therapyinduced myelosuppression or major coexisting illnesses with
relapsed CLL received R/idelalisib or R/placebo
- Median PFS:
Not reached vs 5.5 mo
- Overall response rate:
81% vs 13%
- 12-month overall survival:
92% vs 80%
Mechanism of Action of ABT-199
• Many tumors, particularly lymphoid malignancies, are
addicted to BCL-2 for survival.
• ABT-199 is specific for BCL-2 and induces selective
death of BCL-2-dependent tumor cells while sparing
platelets, which depend primarily on BCL-XL
for survival.
Davids MS, Letai A. Cancer Cell 2013;23(2):139-41.
ABT-199: A Potent and Selective BCL-2 Inhibitor
• Oral, small molecule inhibitor of BCL-2
• Binds with high affinity to BCL-2 and with substantially
lower affinity to other BCL-2 proteins (BCL-XL, BCL-W
and MCL-1)
• Demonstrated preclinical activity as a single agent in a
wide range of hematologic cancer
• Main toxicities reported in relapsed/refractory NHL:
– Primarily Grade 1/2 (minimal Grade 3/4)
– Diarrhea, nausea, fatigue, pyrexia, upper respiratory
tract infection, neutropenia, cough
• Antitumor activity in multiple NHL histologies, including
100% best response rate in MCL

Clinical Issues with the Use of Rituximab
• Infusion-Related Adverse Reactions
• Administration and Dosing

• Phase 3 RATE study (Proc ASH 2011;Abstract 2703)
• FDA approved on October 19, 2012 starting cycle 2
for patients with NHL who did not experience a Grade
3 or 4 infusion-related adverse reaction during cycle 1
– Fixed-dose subcutaneous versus standard intravenous
infusion
• Phase 3 SABRINA study (Lancet Oncol 2014)
• Long-Term Safety
– Hypogammaglobulinemia
– Risk of persistent infections
For your patients receiving R maintenance therapy,
do you generally switch to rapid infusion rate R
(90 minutes) after no complications with an initial
standard-rate infusion?

Case 6 (from the practice of Ms Rogers)
• A 65-year-old man with ALK-negative ALCL whose
disease relapsed on multiple treatments, including
CHOP, pralatrexate, DHAP and radiation therapy
• He received brentuximab vedotin on a clinical trial,
which caused a clinical response but peripheral
neuropathy that was addressed with dose
adjustments, and after completing 16 cycles he
was in CR
• His disease recurred while he was considering
allogeneic SCT
2008: Neoplasm in calf

Mechanism of Action of Brentuximab Vedotin
Brentuximab vedotin is an antibody drug conjugate (ADC)
targeted to cells expressing CD30 on their surface
1 ADC binds to CD30 and
initiates internalization of
the ADC-CD30 complex
2 MMAE is released
3 MMAE binds to tubulin
and disrupts the
microtubule network
