Phase I/II Study of hLL1-DOX in Relapsed NHL and CLL

Phase 1

Terminated

• Conditions: Non-Hodgkin's Lymphoma; Chronic Lymphocytic Leukemia
• Interventions: Drug: hLL1-DOX (IMMU-115)

• Registration Number: NCT01585688
• Lead Sponsor: Gilead Sciences

Brief Summary

The primary objectives are to evaluate the safety and tolerability of hLL1-DOX, and to determine the maximum tolerated dose (MTD) regimen (in terms of a dose and its associated dosing schedule). The secondary objectives are to obtain information on efficacy, pharmacodynamics, pharmacokinetics, and immunogenicity, and to determine the optimal dose for subsequent studies.

Detailed Description

Patients receive hLL1-DOX at one of 4 dose levels administered on Days 1, 4, 8 and 11 of 21-day treatment cycles which are continued in the absence of progression or unacceptable toxicity up to a total of 8 cycles. After treatment, follow-up will be done at 4, 8 and 12 weeks post-treatment and will continue to be done every 3 months for up to 2 years.

• Patients with recent (≤ 6 months) cardiac angina, difficult to control congestive heart failure, uncontrolled hypertension, or difficult to control cardiac arrhythmias will be excluded
• Known autoimmune disease or presence of autoimmune phenomena
• At least 7 days beyond any infection requiring intravenous antibiotic use (Oral antibiotics may be administered prophylactically as clinically indicated)
• Systemic corticosteroids within 2 weeks, except low dose regimens (prednisone, ≤ 20 mg/day, or equivalent) which may continue if unchanged
• Substance abuse or other concurrent medical or psychiatric conditions that, in the Investigator's opinion, could confound study interpretation or affect the patient's ability to tolerate or complete the study

Group	Intervention	Description
hLL1-DOX	hLL1-DOX (IMMU-115)	-

Primary Outcome Measures

Name	Time	Method
Evaluate the safety and tolerability of hLL1-DOX	These assessments will be done routinely during treatment & changes at 4, 8 & 12 weeks after treatment	NCI CTCAE version 4.0 is used to grade all adverse events
All patients who were treated and meet the efficacy criteria for response assessment will be included in the analysis of efficacy	During treatment and the changes at 4, 8 and 12 weeks after treatment and then every 3 months for up to 2 years	For the primary efficacy evaluations, the proportion of responders (defined as patients with a best response of PR or CR) will be tabulated for each dose level. In addition, the progression-free survival (PFS, as measured from start of treatment to disease progression, death or last follow-up) will be summarized using Kaplan-Meier survival analysis methods.; Similarly, for responders at each dose level, the duration of response (DR, as measured from time of first response to relapse or last follow-up) will also be summarized using Kaplan- Meier survival analysis methods, if appropriate.
