Use of a New Medicine "Daratumumab" to Treat Left-over Cancer in a Blood Cancer Called "T Acute Lymphoblastic Leukemia"

T-ALL (T-acute lymphoblastic leukemia) is an aggressive blood cancer, wherein patients who are MRD positive after two courses of induction chemotherapy have poor outcomes. This goal of this study is to determine if Daratumumab can make such T-ALL patients MRD negative. The main questions this study aims to answer are - 1. Whether MRD Positive T-ALL patients can become MRD negative after two doses of daratumumab? 2. Whether MRD Positive T-ALL patients can become MRD negative after four doses of daratumumab? 3. Whether addition of daratumumab can affect the risk of progression or death at 1-year? 4. Whether daratumumab is safe to use? Newly diagnosed patients of T-ALL who are MRD positive after two courses of induction chemotherapy will be eligible to receive daratumumab. These patients will receive two doses of weekly intravenous daratumumab at standard dose (16mg/kg), and will undergo repeat evaluation of MRD from bone marrow one week after the second dose of daratumumab. Patients who become MRD negative will continue chemotherapy as per institutional policy. Those who remain MRD positive will be eligible to receive two additional doses, and will undergo another bone marrow MRD testing one week after the fourth dose. Irrespective of the results after the fourth dose, patients will be continued on chemotherapy as per institutional policy.
