Paclitaxel trevatide (formerly known as ANG 1005 or GRN 1005) is a paclitaxel-peptide drug conjugate, where three paclitaxel molecules linked by a cleavable succinyl ester linkage to a brain peptide vector, Angiopep-2. Paclitaxel trevatide is an oncology product to leverage the low-density lipoprotein receptor-related protein 1 (LRP-1) pathway to cross the blood-brain barrier (BBB) and enter cancer cells. This drug successfully completed phase II clinical trials in breast cancer patients with recurrent brain metastases and in patients with high-grade glioma. 30-May-2014 Angiochem, the company that developed this drug, announced that the Food & Drug Association (FDA) had granted both orphan drug and fast track designation to paclitaxel trevatide for the treatment of glioblastoma multiforme (GBM). In addition, paclitaxel trevatide is going to be involved in phase III clinical trial to see if this drug can prolong survival compared to a Physician Best Choice control in HER2-negative breast cancer patients with the newly diagnosed leptomeningeal disease and previously treated brain metastases.

Tertomotide (also known as GV1001) is a synthetic telomerase-specific peptide vaccine patented by Norsk Hydro Asa for the cancer treatment. The agent was initially developed as a cancer vaccine, for example, against pancreatic and prostate cancer. Telomerase, a reverse transcriptase normally repressed in healthy cells, is overexpressed in most cancer cells and plays a key role in cellular proliferation. Vaccination with Tertomotide may activate the immune system to mount a cytotoxic T-lymphocyte response against telomerase-expressing cells. Subsequently, in vivo studies have demonstrated the efficacy of Tertomotide in alleviating benign prostatic hyperplasia (BPH) symptoms by reducing the size of the prostate gland. The mechanism of action of Tertomotide has been proposed to be through its dual activity as a GnRH inhibitor and 5a-reductase inhibitor. The GnRH antagonist activity has been established by co-immunoprecipitation assay, demonstrating an interaction between Tertomotide and the GnRH receptor, which was abolished by pre-treatment with anti-GnRH receptor antibody.
