Brief Summary:
This study evaluates MBC-11 (a conjugate of a bone-targeting vehicle (etidronate) and a cytostatic agent [ara-C] in patients with malignant tumors with CIBD. This is a first use in human.

Condition or disease Intervention/treatment Phase
Bone Metastasis Drug: MBC-11 Phase 1

Detailed Description:

A standard "3+3" dose escalation design to determine Maximum Tolerated Dose with consecutive different dose level cohort recruitment.

The following dose levels to be investigated: 0.5 mg/kg, 1.0 mg/kg, 2.5 mg/kg, 5.0 mg/kg, 10 mg/kgm 20 mg/kg. The study for each patient consists of 14-days screening period, single dose administration of MBC-11 followed by 7-day safety monitoring and then 2 cycles of multiple use of MBC-11 (28 days each cycle, study drug is administered at Days1-5). In case of partial metabolic reaction/stable metabolic reaction therapy maybe prolonged up to 4 cycles (at investigator and sponsor consideration)

Arm Intervention/treatment
Experimental: dose escalation of MBC-11
MBC-11 was administered in 5 consecutively recruited cohort in dose 0.5 mg/kg, 1 mg/kg, 2.5 mg/kg, 5 mg/kg,10 mg/kg accordingly. The dose escalation is aimed at determining the maximum tolerated dose (MTD)
 Drug: MBC-11
0.5 mg/kg-10 mg/kg , IV (in the vein) on day 1-5 of each 28 day cycle. Number of cycles: 2, in case of partial metabolic reaction or stable metabolic reaction - up to 4.
