Detailed Description
This is a Phase 1, single-arm, open-label, multi-center study designed to determine an effective and well-tolerated dose and schedule of pralatrexate when administered concurrently with vitamin B12 and folic acid supplementation to patients with relapsed or refractory CTCL. The start of study treatment is defined as the initiation of pralatrexate. A patient may begin pralatrexate, provided he/she has methylmalonic acid (MMA) serum concentrations < 200 nmol/L and homocysteine (Hcy) concentrations < 10 μmol/L at screening. If a patient has elevated MMA and/or Hcy concentrations, vitamin supplementation will be initiated at least 10 days prior to pralatrexate initiation. Once the patient is on study, the dosing of vitamin supplementation must adhere to the schedule defined by the protocol. Vitamin supplementation will consist of vitamin BB12
1 mg intramuscular (IM) every (q) 8-10 weeks, and folic acid 1 mg by mouth (PO) once a day (QD).

- Methylmalonic acide (MMA) serum concentration < 200 nmol/L and homocysteine (Hcy) concentration < 10 μmol/L at screening, or receipt of 1 mg daily oral folic acid for at least 10 days prior to the planned start of pralatrexate and 1 mg intramuscular vitamin B12 within 10 weeks of the planned start of pralatrexate.
- Women of childbearing potential must use a medically acceptable contraceptive regimen from study treatment initiation until at least 30 days after the last dose of pralatrexate and must have a negative serum pregnancy test within 14 days prior to the first day of study treatment. Serum pregnancy test not required for patients who are postmenopausal (greater than 12 months since last menses) or are surgically sterilized.

- Written informed consent and privacy authorization.
Exclusion Criteria:
- Active concurrent malignancy (except non-melanoma skin cancer or carcinoma in situ of the cervix). If there is a history of prior malignancy, the patient must be disease-free for ≥ 5 years. Patients with other prior malignancies < 5 years before study entry may be enrolled if treatment resulted in complete resolution of the cancer and currently have no clinical, radiologic, or laboratory evidence of active or recurrent disease.
- Congestive heart failure Class III/IV per the New York Heart Association Heart Failure Guidelines.
- Uncontrolled hypertension.
- Human immunodeficiency virus (HIV)-positive diagnosis with a CD4 count of <100 mm3 or detectable viral load within the past 3 months, and is receiving combination anti-retroviral therapy.
- Symptomatic central nervous system metastases or lesions for which treatment is required.
- Active uncontrolled infection, underlying medical condition that would impair ability to receive protocol treatment.
- Major surgery within 2 weeks of planned start of treatment.
- Receipt of any conventional chemotherapy or radiation therapy (RT) encompassing >10% of bone marrow within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to study treatment or planned use during the study.
- Receipt of systemic corticosteroids within 3 weeks of study treatment, unless on a continuous dose of ≤10 mg/day of prednisone for at least 1 month.
- Initiation of or change in dosage of topical corticosteroids within 3 weeks of study treatment (topical steroid use within 3 weeks is allowed if strength/use has been stable for at least 1 month; topical corticosteroids cannot be started during the study).
- Use of investigational drugs, biologics, or devices within 4 weeks prior to study treatment or planned use during the study.
- Receipt of a monoclonal antibody within 3 months without evidence of progression.
- Use of oral retinoids within 4 weeks of study treatment or high-dose vitamin A.
- Previous exposure to pralatrexate, unless the patient was on this study, achieved a complete or partial response, and was taken off study treatment because of investigator decision, and subsequently experienced disease recurrence or progressive disease.
- Re-entering patients: must not have received subsequent therapy for CTCL during the time off initial study treatment.

Intravenous (IV) push over 3-5 minutes into a patent IV line containing normal saline (0.9% sodium chloride). Pralatrexate will be administered via intravenous (IV) push over 3-5 minutes.

---|---|---|
Determine an Effective and Well-tolerated Dose and Schedule of Pralatrexate with Vitamin B12 and Folic Acid Supplementation for Patients with Relapsed or Refractory Cutaneous T-cell Lymphoma (CTCL)
Time Frame: Assessed at the end of every even-numbered cycle (every 8 weeks) for the first 6 months, then every 4 cycles (16 weeks)
|
Response rate was used as the primary measure of efficacy during the process of identifying a well-tolerated and effective dosing regimen of pralatrexate in patients with relapsed/refractory CTCL.
Duration of response was defined as the number of days between the date of first tumor response assessment of objective response (CR, CRu, or PR, whichever was recorded first) and the first date that recurrent disease or PD was objectively documented or death.

Assessed at the end of every even-numbered cycle (every 8 weeks) for the first 6 months, then every 4 cycles (16 weeks)

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Characterize the Safety Profile of Pralatrexate in Patients with Relapsed or Refractory CTCL.
Time Frame: Assessed at all study visits: weekly while on treatment and at safety follow-up (35 +/- 5 days post-last dose) or early termination visit (at time of withdrawal)
|
The safety analysis set included all patients who received at least 1 dose of pralatrexate. In order to be considered evaluable in the dose-finding phase of the study, patients must have (a) either experienced a DLT or (b) received all planned doses within the first cycle. Patients who terminated from the study prior to completion of cycle 1 for reasons other than DLTs were replaced. |
Assessed at all study visits: weekly while on treatment and at safety follow-up (35 +/- 5 days post-last dose) or early termination visit (at time of withdrawal)
