Detailed Description
PRIMARY OBJECTIVES:
I. Evaluate the safety and determine the maximum tolerated dose (MTD) of ADCT-602 in patients with relapsed or refractory B-cell (B)-acute lymphoblastic leukemia (ALL) in Phase 1.
II. Determine the recommended dose of ADCT-602 for Phase 2. III. Evaluate the efficacy (complete response [CR] with incomplete marrow recovery [CR/CRi] rate) of ADCT-602 in Phase 2.
SECONDARY OBJECTIVES:
I. Evaluate the clinical activity of ADCT-602, based on duration of response (DOR), overall survival (OS), and progression-free survival (PFS).
II. Characterize the pharmacokinetic (PK) profile of ADCT-602. III. Evaluate the immunogenicity of ADCT-602. IV. Characterize the effect of ADCT-602 exposure on the QT interval.
EXPLORATORY OBJECTIVES:
I. Obtain preliminary data on the correlation between the clinical activity and PK profile of ADCT-602 with the baseline expression of CD22 and other cluster of differentiation (CD) markers in peripheral blood.
II. Assess the impact of soluble CD22 (sCD22) on ADCT-602 PK.
OUTLINE: This is a dose escalation study followed by a phase II study.
Patients receive ADCT-602 intravenously (IV) over 30 minutes on day 1. Courses repeat every 21 in the absence of disease progression or unacceptable toxicity. Patients who achieve CR/CRi receive ADCT-602 every 28 days.
After completion of study treatment, patients are followed up at 30 days and then every 12 weeks for up to 1 year.

Negative urine or serum beta-human chorionic gonadotropin (B-HCG) pregnancy test within 7 days prior to the cycle 1, day 1 visit, for women of child-bearing potential. Women of child bearing potential must agree to use an effective method of contraception from the time of giving informed consent until at least 16 weeks after the last dose of ADCT-602. Men with female partners who are of child bearing potential must agree that they or their partners will use a highly effective method of contraception from the time of giving informed consent until at least 16 weeks after the patient receives his last dose of ADCT-602
- Women of child bearing potential defined as: Sexually mature women who have not undergone bilateral tubal ligation, bilateral oophorectomy, or hysterectomy; or who have not been postmenopausal (i.e., who have not menstruated at all) for at least 1 year
Effective method of contraception defined as: Hormonal contraceptives (oral, injectable, patch, intrauterine devices), male partner sterilization, or total abstinence from heterosexual intercourse, when this is the preferred and usual lifestyle of the patient
- NOTE: The double-barrier method (e.g., synthetic condoms, diaphragm, or cervical cap with spermicidal foam, cream, or gel), periodic abstinence (such as calendar, symptothermal, post ovulation), withdrawal (coitus interruptus), lactational amenorrhea method, and spermicide-only are not acceptable as highly effective methods of contraception
- White blood cell (WBC) value of < 15,000 cells/uL prior to cycle 1 day 1
Exclusion Criteria:
Known active central nervous system (CNS) leukemia, defined as morphologic evidence of lymphoblasts in the cerebrospinal fluid (CSF), or symptomatic CNS leukemia (i.e., cranial nerve palsies or other significant neurologic dysfunction) within 28 days prior to screening.
- NOTE: Patients may have a history of CNS leukemic involvement if they have received prior treatment for CNS involvement and no evidence of active disease (defined as >= 2 consecutive spinal fluid assessments with no evidence of disease) is present at screening. Prophylactic intrathecal chemotherapy is allowed on the trial and is not a criterion for exclusion
- Patients with Burkitt's leukemia/lymphoma
- Active graft-versus-host disease (GVHD) or severe/extensive chronic GVHD

Major surgery, chemotherapy, systemic therapy (excluding hydroxyurea, steroids and any targeted small molecules or biologics), or radiotherapy within 14 days or 5 half-lives (whichever is shorter) prior to cycle 1, day 1 treatment
- NOTE: a) To reduce the circulating lymphoblast count or palliation: steroids and hydroxyurea are allowed. No washout necessary for these agents. b) Cytarabine IV could be used for cytoreduction with a washout of 1 week. c) For ALL maintenance/treatment: mercaptopurine, oral methotrexate, vincristine, and/or tyrosine kinase inhibitors.
