DRUG TRIALS SNAPSHOT SUMMARY:
What is the drug for?
POTELIGEO is used to treat adults with mycosis fungoides (MF) or Sézary syndrome (SS) who have received at least one prior systemic (such as injections or pills) treatment for their disease but the treatment did not work or the disease has come back.
MF and SS are rare types of cancer called cutaneous T-cell lymphoma which form in the lymph system and affect the skin.
How is this drug used?
POTELIGEO is given by a healthcare provider directly into the bloodstream through a needle in the vein. This is known as an intravenous, or IV infusion. It takes about one hour to receive a POTELIGEO infusion.
POTELIDEO is given on days 1, 8, 15, and 22 of the first 28-day cycle and on days 1 and 15 of each subsequent cycle.
What are the benefits of this drug?
In the trial, patients who received POTELIGEO experienced longer period of time a patient stays alive without the cancer growing (called progression-free survival) in comparison to patients who received vorinostat (a type of chemotherapy) . For patients treated with POTELIGEO it took about 7.6 months before disease progression and for patients treated with vorinostat about 3.1 months.
Were there any differences in how well the drug worked in clinical trials among sex, race and age?
- Sex: POTELIGEO worked similarly in men and women.
- Race: Most of the patients were White. Differences in how well the drug worked among races could not be determined because of the small number of patients in other races.
- Age: POTELIGEO worked similarly in patients younger and older than 65 years of age.
What are the possible side effects?
POTELIGEO may cause serious side effects including life threatening rash, infusion reactions, infections, and worsening of autoimmune diseases and complications of stem cell transplantation.
The most common side effects of POTELIGEO are rash, infusion related reactions, fatigue, diarrhea, musculoskeletal pain, and upper respiratory tract infection.
Were there any differences in side effects among sex, race and age?
- Sex: The occurrence of side effects was similar in men and women.
- Race: Most of the patients were White. Differences in the occurrence of side effects among races could not be determined because of the small number of patients in other races.
- Age: The occurrence of side effects was similar in patients younger and older than 65 years of age.
WHO WAS IN THE CLINICAL TRIALS?
Who participated in the clinical trials?
The FDA approved POTELIGEO based on evidence from one clinical trial (NCT01728805) which enrolled 372 patients with MF or SS who had received at least one prior therapy for the disease.
The trial was conducted in United States, Europe, Japan and Australia.
Figure 1 summarizes how many men and women were in the clinical trial.

How were the trials designed?
There was one trial that evaluated the benefit and side effects of POTELIGEO in patients with MF or SS who had received at least one prior systemic therapy.
Half of the patients received POTELIGEO infusion and the other half vorinostat capsules (a previously approved drug to treat skin lymphoma). POTELIGLEO was given once a day on days 1, 8, 15, and 22 of the first 28-day cycle and on days 1 and 15 of each subsequent cycle and vorinostat capsules daily for 28-day cycles. Both, patients and health care providers knew which treatment was given.
Treatment continued until disease progression or unacceptable side effects.
The benefit of POTELIGEO was evaluated by measuring the length of time during which patients stay alive without the cancer growing (progression-free survival or PFS) and comparing it to PFS in patients who took vorinostat.
GLOSSARY
CLINICAL TRIAL: Voluntary research studies conducted in people and designed to answer specific questions about the safety or effectiveness of drugs, vaccines, other therapies, or new ways of using existing treatments.
COMPARATOR: A previously available treatment or placebo used in clinical trials that is compared to the actual drug being tested.
EFFICACY: How well the drug achieves the desired response when it is taken as described in a controlled clinical setting, such as during a clinical trial.
PLACEBO: An inactive substance or “sugar pill” that looks the same as, and is given the same way as, an active drug or treatment being tested. The effects of the active drug or treatment are compared to the effects of the placebo.
SUBGROUP: A subset of the population studied in a clinical trial. Demographic subsets include sex, race, and age groups.
