Study Details

Study Description

Brief Summary

In the United States, thiotepa has been utilized in reduced intensity conditioning regimens for alternative donor courses (double umbilical cord blood transplant (dUCBT) and haplo-identical transplants).

The hypothesis is that thiotepa at a dose of 10mg/kg, in combination with melphalan (100mg/m2) and fludarabine (160mg/m2) as a reduced intensity conditioning regimen for alternative donor transplant is safe and effective in patients with hematologic malignancies.

Given that this regimen has been investigated extensively, and the current study proposes to confirm those previous observations with a small modification (melphalan dose reduction due to previous mucositis rates with higher doses), this will be a phase II study designed to measure disease-free-survival.

Condition or Disease	Intervention/Treatment	Phase
Leukemia	Drug: Melphalan Drug: Thiotepa Drug: Fludarabine Drug: Keratinocyte Growth Factor (KGF)	Phase 2

Detailed Description

Primary Objective:

To assess the effectiveness of Thiotepa, Fludarabine, and Melphalan in alternative donor transplants as measured by leukemia free survival.

Secondary Objective:

To assess the 1- year OS, Relapse, TRM, aGVHD and cGVHD rates and the rates of neutrophil and platelet engraftment.

Study Design This is a Phase II study of Thiotepa, Fludarabine, and Melphalan in alternative donor transplants.

Subjects will be assessed for safety and tolerability (including adverse events, serious adverse events, and clinical/laboratory assessments) using a continuous monitoring approach. Subjects will be followed for up to 1 year or until progression of disease, relapse, or death.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Thiotepa + Fludarabine + Melphalan + KGF Melphalan 100 mg/m2 on day -8 Thiotepa 10 mg/kg on day -7 Fludarabine 160 mg/m2 in divided doses given on days -6, -5, -4 and -3. Keratinocyte Growth Factor (KGF) 60mcg/kg IV on day -11, -10, and -9 and 0, +1, and +2.	Drug: Melphalan Alkylating agent which is a derivative of mechlorethamine that inhibits DNA and RNA synthesis via formation of carbonium ions; cross-links strands of DNA; acts on both resting and rapidly dividing tumor cells. Melphalan may cause a lowering of the white blood cell or platelet counts, leading to an increased risk of infection and frequent bruising or bleeding. It may cause damage to the GI tract causing mouth sores, nausea, vomiting, and diarrhea. Other side effects may include loss of appetite, liver abnormalities, hair loss, swelling, fatigue, sleepiness, skin rash. Other Names: Alkeran Evomela Drug: Thiotepa Thiotepa is an alkylating agent which produces cross-linking of DNA strands leading to inhibition of DNA, RNA, and protein synthesis; thiotepa is cell-cycle independent. Thiotepa may cause a lowering of the white blood cell or platelet counts, leading to an increased risk of infection and frequent bruising or bleeding. It may cause damage to the GI tract causing mouth sores, nausea, vomiting, and diarrhea. Other side effects may include loss of appetite, liver abnormalities, hair loss, swelling, fatigue, sleepiness, skin rash. Other Names: Tepadina Drug: Fludarabine Fludarabine is an antineoplastic fluorinated nucleoside analog and inhibits DNA synthesis through inhibition of polymoerase alpha after incorporation into DNA. Fludarabine may cause a lowering of the white blood cell or platelet counts, leading to an increased risk of infection and frequent bruising or bleeding. Other side effects may include loss of appetite, liver abnormalities, hair loss, swelling, fatigue, sleepiness, skin rash, and lower limb weakness. Other Names: Fludara Drug: Keratinocyte Growth Factor (KGF) Chemoprotective Agent.Recombinant keratinocyte growth factor (KGF) produced in E. coli. KGF binds to the KGF receptor resulting in proliferation, differentiation and migration of epithelial cells in multiple tissues, including (but not limited to) the tongue, buccal mucosa, esophagus, and salivary gland. Palifermin may cause rash, itching, redness, or discoloration of the skin. It may cause edema, an increase in pancreatic enzymes. It may cause arthralgias. It may cause tongue discoloration or tongue edema. Other Names: Palifermin Kepivance K
