Health Canada has granted conditional approval for pralatrexate (Folotyn®) to treat relapsed or refractory peripheral T-cell lymphoma (PTCL).

Pralatrexate received a Notice of Compliance with Conditions (NOC/c), which is an approval granted on the basis of promising evidence of clinical effectiveness that must be verified in additional clinical trials.

To be approved under Health Canada’s NOC/c policy, a product must be intended for the treatment, prevention, or diagnosis of a serious, life-threatening, or severely debilitating illness.

In addition, the product must have demonstrated promising benefit, be of high quality, have an acceptable safety profile based on a benefit/risk assessment, and either respond to a serious unmet need or provide a significant improvement over existing therapies.

The NOC/c for pralatrexate is based on response rates in the single-arm, phase 2 PROPEL trial. Results from PROPEL were published in the Journal of Clinical Oncology in 2011.

The trial enrolled 115 patients with relapsed or refractory PTCL who had received a median of three (range, 1-12) prior systemic therapies.

The patients received pralatrexate once weekly at a dose of 30 mg/m² for 6 weeks in 7-week cycles until disease progression or unacceptable toxicity.

In the 109 evaluable patients, the response rate was 29% (32/109). The complete response rate was 11% (n=12), and the partial response rate was 18% (n=20).

The median duration of response was 10.1 months, the median progression-free survival was 3.5 months, and the median overall survival was 14.5 months.

The most common adverse events (AEs) were mucositis (71%), thrombocytopenia (41%), nausea (41%), fatigue (36%), pyrexia (34%), anemia (34%), constipation (34%), edema (31%), cough (29%), epistaxis (26%), vomiting (25%), neutropenia (25%), and diarrhea (23%).

The most common grade 3/4 AEs were thrombocytopenia (32%), mucositis (22%), neutropenia (22%), and anemia (18%).

The product monograph for pralatrexate contains a boxed warning highlighting the risk of AEs associated with pralatrexate use, including dermatologic reactions, bone marrow suppression, infection, mucosal inflammation, tumor lysis syndrome, potential fetal harm, and pulmonary toxicity.

The product monograph is available for download from the website of Servier Canada, the company marketing pralatrexate in Canada.
