Phase IIb Clinical Trial With TGF-β2 Antisense Compound AP 12009 for Recurrent or Refractory High-grade Glioma

Study Purpose

In this multinational dose finding Phase IIb study the efficacy and safety of two doses of AP 12009 compared to standard chemotherapy (temozolomide or PCV) is investigated in adult patients with confirmed recurrent high-grade glioma.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT00431561
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

The purpose of this study is to compare the safety and efficacy of two doses of AP 12009 and standard chemotherapy in adult patients with recurrent high-grade glioma (anaplastic astrocytoma [AA], WHO grade III; or glioblastoma [GBM], WHO grade IV). AP 12009 is a phosphorothioate antisense oligodeoxynucleotide specific for the mRNA of human transforming growth factor-beta2 (TGF-beta2). The growth factor TGF-beta plays a key role in malignant progression of various tumors by inducing proliferation, invasion, metastasis, angiogenesis and escape from immunosurveillance. It has been shown that in a number of tumor types the degree of TGF-beta production strongly correlates with tumor grade and stage. In patients with high-grade glioma, the TGF-beta2 overexpression is associated with disease stage, clinical prognosis and the immunodeficient state of the patients.
