Minimum age
18 Years
Maximum age

Sex

Can healthy volunteers participate?
No
Key exclusion criteria
- Clinically significant non-malignant disease including, but not limited to, major surgery within 6 weeks of randomisation, active clinically significant infection, myocardial infarction within 6 months prior to randomisation, cerebrovascular event or transient ischaemic attack within 12 months prior to randomisation or clinically significant gastrointestinal bleeding within 12 months prior to randomisation. Anti-cancer therapy within 4 weeks of Cycle 1 day 1 (excluding GnRH agonists for prostate cancer). Palliative radiation for bone metastases within 2 weeks of Cycle 1 day 1.
- Active CNS metastases. Subjects with prior CNS metastases treated by surgery and/or stereotactic irradiation are eligible providing they have no evidence of active disease at screening. Subjects with prior CNS metastases treated with only whole brain radiation therapy are ineligible.
- Subjects with uncontrolled diabetes.
- History of allergy and / or hypersensitivity and / or other clinically significant adverse drug reaction to heparin or other anti-coagulant agents.
- History of immune-mediated thrombocytopaenia or other platelet abnormalities or other hereditary or acquired coagulopathies, or laboratory evidence of anti-heparin antibodies, or any previous history of having tested positive for anti-heparin antibodies.
- Concomitant use of aspirin (> 150 mg/day), non steroidal anti-inflammatory drugs (except COX-2 selective inhibitors), vitamin K antagonists (other than low-dose prophylactic use), heparin within two weeks prior to randomisation, or other anti-platelet drugs (e.g. abciximab, clopidogrel, dipyridamole, ticlopidine and tirofiban). Low-dose aspirin (= 150 mg/day) and low dose prophylactic vitamin K antagonists (e.g. warfarin = 1 mg/day) are permitted as concomitant medications.
- History of severe allergic, anaphylactic or other significant adverse reaction to radiographic contrast media (iodinated or non-iodinated), which cannot be managed by pre treatment with agents such as steroids or anti histamines, and which, in the opinion of the Investigator, renders the subject unsuitable for routine CT or MRI scanning. Subjects who are contra-indicated for CT or MRI scanning for other reasons (e.g. ferromagnetic implants, profound claustrophobia), should not be enrolled.
- Known seropositivity to the human immunodeficiency virus (HIV).
- Women who are pregnant or breast-feeding.
- Women of child-bearing potential and male subjects who are partners of women of childbearing potential who are unable or unwilling to practice a highly effective means of contraception. Effective birth control includes: a) birth control pills, depot progesterone, or an intrauterine device plus one barrier method, or b) two barrier methods. Effective barrier methods are: male and female condoms, diaphragms, and spermicides (creams or gels that contain a chemical to kill sperm).
- Active substance abuse, including alcohol, which, in the opinion of the Investigator, risks impairing the ability of the subject to comply with the protocol.
- Subjects who have received an investigational agent within 28 days prior to Cycle 1 Day 1; or are currently participating in any other clinical study or research project which involves administration of a pharmaceutical product or experimental treatment, or which involves protocol-specified laboratory tests, imaging studies or other investigations.

Summary
Brief summary
This study aims to establish the maximum tolerated dose of PG545 and to evaluate its safety in subjects with advanced solid tumours.

Who is it for? You may be eligible to join this study if you are a male or female aged 18 years or above who has been diagnosed with a non haematological malignant solid tumour, excluding primary brain or spinal tumours. To be eligible patients must have failed all standard therapies, no longer be a candidate for standard therapy, have no standard therapy available, or have chosen not to pursue standard therapy.

Study details: All participants in this study will receive the drug PG545 once weekly via a 1 hour intravenous infusion (i.e. directly into the vein). Subjects will be treated until either disease progresses or they can't have further treatment due to tolerability. They will be regularly monitored throughout the treatment period in order to determine the safety and tolerability of treatment. The dose of PG545 will also be increased in new groups of patients in order to determine the maximum tolerated dose. In addition the study will explore whether PG545 exposure results in changes to chemicals produced by the body that are associated with cancer growth and spread. This is the first clinical study of PG545 administered by intravenous infusion.
