Study Description

Brief Summary:

This study is to evaluate the effect of leucovorin in preventing or reducing Folotyn-related Grade 2 or higher oral mucositis.

Condition or disease	Intervention/treatment	Phase
Relapsed Peripheral T-Cell Lymphoma; Refractory Peripheral T-Cell Lymphoma	Drug: Folotyn and Leucovorin; Drug: Folic Acid; Drug: Vitamin B12	Phase 2

Detailed Description:

This is a Phase 2, single-arm, open-label, multicenter study to determine the effect of leucovorin in preventing or reducing Folotyn-related Grade 2 or higher oral mucositis in patients with hematological malignancies including PTCL and CTCL.

Patients with hematological malignancies, including PTCL and CTCL, will be enrolled based on meeting all protocol eligibility criteria. The primary endpoint will be evaluated in the first 7-week treatment cycle. For patients who respond to study treatment, the Investigator can treat patients for a total of 6 cycles. Approximately 37 patients will be enrolled. Safety, as assessed by reported SAEs, will continue to be monitored during the optional treatment period. Efficacy will be followed to the extent that it is evaluated according to the Institution's standard of care. No formal analysis of efficacy will be made.

Arms and Interventions

Arm

Intervention/treatment

Experimental: Folotyn and Leucovorin; Folotyn will be administered by IV push at a dose of 30 mg/m2 once weekly for 6 weeks in each cycle, followed by 1 week of rest (no treatment). Leucovorin (25 mg tablets) will be taken orally tid for 2 days for a total of six doses (150 mg cumulative weekly dose), beginning 24 hours after each dose of Folotyn is administered. Folic acid and Vitamin B12 is given prior to initiation of Folotyn.

Drug: Folotyn and Leucovorin; Other Name: Pralatrexate (Folotyn); Drug: Folic Acid; Folic acid (1.0 mg PO QD) is to be initiated at least 10 days prior to Folotyn administration, or per the USPI for Folotyn.; Drug: Vitamin B12; Vitamin B12 (1 mg IM) is to be administered within 10 weeks prior to initiation of Folotyn and can be administered during Screening. Subsequent vitamin B12 injections may be given the same day as treatment with Folotyn and patients are to receive vitamin B12 every 8 to 10 weeks while treated with Folotyn.

Outcome Measures

Primary Outcome Measures :

1. Grade 2 Oral Mucositis Prevention [ Time Frame: 15 weeks ]
   To evaluate the effect of leucovorin in preventing or reducing Folotyn-related Grade 2 or higher oral mucositis.

Secondary Outcome Measures :

1. Grade 3 Oral Mucositis Prevention [ Time Frame: 15 weeks ]
   To evaluate the effect of leucovorin in preventing or reducing Folotyn-related Grade 3 or higher oral mucositis.
2. Grade 2 Oral Mucositis Duration of first occurrence [ Time Frame: 15 weeks ]
   To evaluate the time to first occurrence of Folotyn-related Grade 2 or higher oral mucositis.
3. Grade 2 Oral Mucositis Duration [ Time Frame: 15 weeks ]
   To evaluate the duration of Folotyn-related Grade 2 or higher oral mucositis.
4. Effectiveness of Leucovorin in Folotyn dose modification [ Time Frame: 15 weeks ]
   To evaluate the effect of leucovorin on the number and proportion of patients whose subsequent dose of Folotyn is omitted, delayed, or reduced due to the onset of oral mucositis.
5. Objective Response Rate [ Time Frame: 17 weeks ]
   To evaluate objective response rate (ORR) of Folotyn in patients with relapsed or refractory (R/R) PTCL.
