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.

Conditions

Interventions

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.

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.

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.
