The following is a roundup of TPS abstracts that feature trials open to patients aged >17 years with a broad range of cancer types.
The Trials in Progress Poster Session (TPS), which was held at the ASCO meeting in June and is now in its second year, is intended to stimulate discussion in the oncology community about ongoing clinical trials and to promote collaboration. The following is a roundup of TPS abstracts that feature trials open to patients aged ≥18 years with a broad range of cancer types.
Radiation therapy plus temozolomide with cilengitide or cetuximab in poor-prognosis glioblastoma
This phase II study will determine the effect of radiation therapy (RT) plus temozolomide (TMZ) combined with cilengitide or cetuximab in patients with newly diagnosed glioblastoma multiforme (GBM) with an unmethylated promoter of the O6-methylguanine-DNA-methyltransferase (MGMT) gene. An unmethylated MGMT-promoter is associated with a notoriously poor prognosis. All participants will receive postoperative RT with daily concomitant TMZ followed by adjuvant TMZ, and will then be randomized to additional treatment with either the integrin inhibitor cilengitide or the monoclonal epidermal growth factor receptor (EGFR)-targeted antibody cetuximab. The primary endpoint is the 1-year overall survival (OS). Secondary endpoints include progression-free survival (PFS) and safety. Abstract TPS134.

Trastuzumab-DM1 (T-DM1) with or without pertuzumab versus trastuzumab plus a taxane for first-line treatment of metastatic breast cancer
This global phase III study will evaluate the efficacy and safety of T-DM1 with or without pertuzumab compared with trastuzumab plus either docetaxel or paclitaxel in women with human epidermal growth factor receptor 2 (HER2)-positive, progressive or recurrent locally advanced or metastatic breast cancer (MBC). T-DM1 is a unique antibody-drug conjugate that combines the antitumor activities of trastuzumab with intracellular delivery of the highly potent cytotoxic agent DM1 (derivative of maytansine). T-DM1 plus pertuzumab has demonstrated synergistic antitumor effects in preclinical models, and preliminary phase Ib/II trial results showed acceptable tolerability and promising efficacy in patients with MBC. The primary endpoint is PFS by independent review facility. Secondary endpoints include safety, overall response rate (ORR), OS, duration of response, and QOL. Thus far, 141 patients have been enrolled and the target recruitment is 1092 patients. The MARIANNE study is the first phase III study to evaluate the combination of a targeted antibody and an antibody-drug conjugate for first-line MBC. The systemic chemotherapy-sparing combination has the potential to establish a new treatment paradigm by optimizing efficacy while minimizing toxicity. Abstract TPS102.

12-weekly intravenous bisphosphonate therapy in women with low-risk bone metastases from breast cancer
This study will examine whether IV bisphosphonates (BPs) can be safely given to breast cancer patients with biochemically defined low-risk bone metastases every 12 weeks. Most patients currently receive an IV BP every 3 to 4 weeks regardless of their individual risk for a skeletal-related event (SRE). This one-size-fits-all strategy exposes individuals who are at a relatively low risk of SREs to the financial and QOL burden of multiple clinic visits for treatments, along with an increased risk of drug toxicity. The primary aim of the study is to demonstrate that the administration of IV BP every 12 weeks is sufficient to maintain biochemical stability for 1 year. The palliative benefit of 12-weekly IV BP therapy as reflected by occurrence of SREs, analgesic use, and self-reported pain (using validated pain measures) will also be evaluated. Abstract TPS242.
