SST0001 (Roneparstat) in Advanced Multiple Myeloma

• Status: Completed
• Trial end date: 2016-11-01
• Target enrollment: 0
• Participant gender: All

Summary

Heparanase cleaves heparan sulfate (HS) chains, a natural substrate for heparanase, and participates in degradation and remodelling of the extra-cellular matrix (ECM) facilitating, among other activities, cell invasion associated with cancer metastasis, angiogenesis, and inflammation. The heparanase enzyme is a promising target for development of new anticancer drugs. HS and the structurally related heparin are present in most animal species. As an analogue of the natural substrate of heparanase HS, heparin is considered to be a potent inhibitor of heparanase. SST0001 is a polymer with a heparin-like structure. It is a reduced oxidized N-acetyl heparin, these modifications cause the reduction of anticoagulant activity and are strictly related to the anti-heparanase activity. In preclinical murine models SST0001 showed a significant anti myeloma effect in multiple myeloma mice xenograft models, with a significant reduction of subcutaneous growth of different multiple myeloma cell lines, when SST0001 was administered either alone or in combination with dexamethasone. The purpose of this study is to determine the safety and tolerability of escalating doses of SST0001 in the treatment of advanced refractory multiple myeloma.

• No known central nervous system involvement by myeloma.

• Capacity of understanding the nature of the trial and giving written informed consent.

• Unless a female patient is post-menopausal or surgically sterilized, must be willing to use an acceptable method of birth control (hormonal contraceptive, intrauterine device, barrier contraceptive with spermicide, or abstinence) for the duration of the study.

• Male patient must agree to use an acceptable method for contraception (barrier contraceptive or abstinence) for the duration of the study.

Exclusion Criteria:

• Pregnancy or lactation or unwillingness to use adequate method of birth control

• Ascertained or presumptive hypersensitivity to the active principle and/or formulations ingredients.

• Active uncontrolled viral, bacterial, or fungal infection or history of HIV, hepatitis B or C, or any infection requiring systemic antivirals or antimicrobials.

• Grade ≥ 2 toxicity due to previous anti-neoplastic therapy (except alopecia), and Grade ≥ 3 peripheral motor or sensory neuropathy, in the 2 weeks before treatment (CTCAE V4.0).

• Less than 2 weeks since most recent chemotherapy, or concurrent chemotherapy.

• Presence of cirrhosis or chronic hepatitis.

• Diagnosis of amyloidosis or diagnosis of plasma cell leukaemia.

• Presence of serious cardiac (congestive heart failure, angina pectoris, myocardial infarction within one year prior to study entry, uncontrolled hypertension or arrhythmia), neurological or psychiatric disorder.

• Presence of uncontrolled intercurrent illness or any condition which in the judgement of the investigator would place the subject at undue risk or interfere with the results of the study.
