Health condition and Intervention

Section to complete information about the primary medical condition(s) or problem(s) studied and, a characteristics of the intervention(s).

Health condition(s) or Problem(s) studied:

Non-Hodgkin lymphoma, Chronic lymphocytic leukemia, Multiple myeloma

Intervention(s):

Stage I 14F mAb intravenously in 5 dose levels (25 mg, 50 mg, 100 mg, 200 mg o 400 mg) every 15 days (5 doses) in induction period and, then every 28 days (4 doses) in maintenance period. Stage II 14F mAb intravenously in 2 dose level for each cohort of patients according to health condition. One dose level will be the Maximum Tolerable Dose (MTD) obtained in stage I and, the other dose level will be the immediate dose lower or higher than MTD according to the criteria of the protocol. Both dose levels will be administered in the same scheme as stage I.

Outcomes and Timepoint

Section to complete information about primary and secondary outcomes including. It includes the metric or method of measurement used and, the time point for every outcome.

Primary outcome(s):

Stage I Serious Adverse Events (SAE) with causality relationship (Serious Adverse Events those that: 1. Produce death, 2. life-threatening, 3. hospitalization or prolongation of hospitalization indicated, 4. Produce disability / persistent or significant disability, 5. Produce birth defect or congenital anomaly. Will be consider causality relationship when the SAE has definitive/highly probable or probable causality relationship). Measuring time: during and after each administration, throughout the study period until week 52. Stage II Objective response (Complete response y partial response according to the international criteria for each chronic B-cell lymphoproliferative syndrome). Measurement time: weeks 13, 29, 41 and 52

Key secondary outcomes:

Control of the disease (It will to evaluate according to the International response criteria for each chronic B-cell lymphoproliferative syndrome (CLPS) in the categories "Control of the disease" (complete + partial response + stable disease) and "Non-responders" (death + progressive disease) . Measurement time: weeks 13, 29, 41 and 52. Relapse-Free Survival (The time from the date of achievement of a complete response until the date of relapse or death from any cause. Defined only for patients achieving complete response). Measuring time: 52 weeks Event-free survival (The time from treatment began until treatment failure, or relapse or death from any cause). Measurement time: 52 weeks Progression free survival (The time from the start of treatment until to the date of disease progression or death from any cause) Measurement time: 29 and 52 weeks Survival rates (Percentage of patients alive from the diagnosis and the start of treatment). Measuring time: week 29 and week 52 Time to progression (Time measured from the start of treatment to the date of disease progression). Measurement time: 52 weeks Time to treatment failure (Time from the start of treatment to the interruption of treatment for any reason, including disease progression, toxicity or death). Measurement time: 52 weeks Immunogenicity HAHA response (Yes, No. It will be "Yes" when the value of the density of the patient serum is greater than 2 standard deviations of the value of the sera of healthy donor). Measurement time: At baseline, prior to each administration of product, week 29 and week 52. Pharmacokinetics Bioavailability of mAb 14F7hT (numerical value). Measurement time: 1st and 5th administration Volume of distribution of the MAb 14F7hT (numerical value).
