Summary
• The Histopathology of SS is characterized by
•
Epidermotropism (Expression , Pautrier
Microabszesses)
•
Increased Atypical Lymphocytes (cerebriform, blastär)
•
CD7 loss
•
PD-1 und MUM-1 Expression
•
Less CD8+ cells
•
Increased proliferation
• Negative prognostic Marker for SS are diffuse and deep
dermal infiltrates
Goals of Therapy in Patients with
CTCL in 2014
Hope to Cure or increase DFS
Durable Remission lasting > 1yr
PR and decreased symptoms
Stabilize to prevent progression
Recognize and treat infections
Avoid immunosuppression and toxicity
Therapeutic Options for Cutaneous T-cell
Lymphoma, 2014
•
•
•
•
Topical/skin directed therapy
– Topical steroids, , phototherapy (UVB/PUVA), PDT, radiation treatment,
imiquimod
Systemic therapy
– Biologics, targeted therapy:
• Photopheresis, interferon, retinoid (bexarotene), fusion protein/toxin
(denileukin diftitox*), alemtuzumab**
•*FDA approved
– HDAC inhibitors: vorinostat*, romidepsin*
•** taken off the market
– Chemotherapeutics:
• MTX, lipo. doxorubicin, gemcitabine, etoposid, pentostatin, combinations,
pralatrexat (approved for PTCL*)
Combination therapies
– Topical and photo therapy, topical and systemic, systemic + systemic
Investigative therapy
– Monoclonal antibodies (e.g., CD30, CCR4)
- Kinase inhibitors
– TLRA (e.g., CpG, resiquimod)
- Vaccination strategies
– Improved chemotherapeutic, misc.
- Allo transplantation
Disappointing results or not further developed
- Forodesine, Zanolimumab

advanced cutaneous T-cell lymphoma.
The CTCL Platform
• Reasons for failure:
- Complicated study design for the
maintanance study
- Prolongation due to regulatory affairs
- Drug development was stopped
- No aggreement within the BMT group
on one protocol
Arguments for EORTC studies in
cooperation with academic medicine
and industry
EORTC as a label for independance and reputation
in clinical research
EORTC infrastructure with specialized and
experienced expert in clinical studies
EORTC as a clinical integrative research platform
for Pan- European medicine
EORTC as a strong inter-disciplinary network in oncology
Problems for EORTC studies in cooperation
with academic medicine and industry
New drug developments are performed by
pharmaceutical companies under their control and
leadership: Data ownership
Companies do not recognize the additional value of
being asscociated with EORTC
Clinical research is financed directly by clinical
studies provided by pharma industry
Individual centers have a higher profit margin
EORTC‘s reputation is of controversial value
Problems for EORTC studies in cooperation
with academic medicine and industry
How to solve the problems
- Establishing a clinical study group
- Defining new targets for therapy based on
translational research
- Involvement in early drug development
- Performing small and effective Phase I and
II studies
- Performing studies in a given time frame
- Fund raising

• Investigational small molecule
inhibitor of Aurora A kinase
(AAK)
– AAK regulates aspects of cell
mitosis
– Administered orally
– Clinical studies are
evaluating dosing schedules
and pharmacodynamics
– Phase 1 and 2 trials are
ongoing in patients with solid
tumors and hematologic
malignancies
– Phase 3 trial initiated in
relapsed/refractory peripheral
T-cell lymphoma (PTCL)
