Brief Summary

Amblyomin-X is an inhibitor of Factor Xa that also acts as an apoptotic agent for tumor cells. In the case of in vitro assays, Amblyomin-X induces tumor cells to death and does not affect the viability of normal cells. When in vivo assays were performed on mice bearing tumors, treatment with Amblyomin-X caused a significant reduction in tumor mass and number of metastases.

Outcome Measures

Primary Outcomes (1)

  • grade 4 or non-haematological grade 3 haematological toxicity according to the CTCAE (version 4)

    Presence of grade 4 or non-haematological grade 3 haematological toxicity according to the Common Terminology Criteria for Adverse Events (CTCAE, version 4)

    2 weeks

    2 weeks

  • Adverse Events

    4 weeks

Study Arms (6)

Cohort 1

EXPERIMENTAL

This cohort will include 3 patients with the first calculated dose of Amblyomin-X drug. The patient will receive the intravenous drug. If no Dose-limiting toxicity (DLT) in this group the study continues including the next cohort. However, if If only one patient in a given cohort develops DLT, three more patients will be included at that dose level, up to a maximum total of six patients per dose level. If two or more of the three patients of a certain dose level develop DLT, this dose level is considered very toxic, and the study does not proceed. If this occurs at the first dose level, the study will be finalized. If only one in six patients at a dose level develops DLTs, escalation proceeds until Tolerated Maximum Dose.

Biological: Amblyomin-X

Cohort 2

EXPERIMENTAL

This cohort will include 3 patients with the second calculated dose of Amblyomin-X drug. The patient will receive the intravenous drug. If no Dose-limiting toxicity in this group the study continues including the next cohort

Biological: Amblyomin-X

Cohort 3

EXPERIMENTAL

This cohort will include 3 patients with the third calculated dose of Amblyomin-X drug. The patient will receive the intravenous drug. If no Dose-limiting toxicity in this group the study continues including the next cohort

Biological: Amblyomin-X

Cohort 4

EXPERIMENTAL

This cohort will include 3 patients with the fourth calculated dose of Amblyomin-X drug. The patient will receive the intravenous drug. If no Dose-limiting toxicity in this group the study continues including the next cohort

Biological: Amblyomin-X

Cohort 5

EXPERIMENTAL

This cohort will include 3 patients with the fifth calculated dose of Amblyomin-X drug. The patient will receive the intravenous drug. If no Dose-limiting toxicity in this group the study continues including the next cohort

Biological: Amblyomin-X

Cohort 6

EXPERIMENTAL

This cohort will include 3 patients with the sixth calculated dose of Amblyomin-X drug, the last dose calculated. The patient will receive the intravenous drug.

Biological: Amblyomin-X
