RCSI and ALMAC Discovery Partnership to Target the Root of Cancer: Cancer Stem Cells

A New Year…and a new challenge for MCT postdoctoral researcher Gillian Moore¬†

Between the post-Christmas blues, cold days and that painful wait for the next pay day, January can be a pretty long and gruelling month. This year, deviating from the norm, my January kicked off to a great start with my eagerly awaited move to RCSI. Before Christmas I was delighted to find out that I would be working alongside Prof. Tracy Robson in the Department of MCT and I’m really excited for 2017, and the new opportunities and challenges this postdoctoral research position has to offer.
An ongoing research collaboration between the Robson research group and leading oncology pharmaceutical company, ALMAC Discovery, resulted in the development of ALM201, an anti-cancer peptide-based drug currently in Phase I clinical trial for patients with solid tumours. ALM201 is structurally based on the naturally occurring protein, FKBPL. FKBPL and its peptide-derivative, ALM201, have demonstrated potent anti-angiogenic properties, and notably, a unique ability to target cancer stem cells. Targeting of cancer stem cells has arguably become the Holy Grail of cancer therapy in recent years. Within the mass of every tumour there is a subpopulation of cancer cells with the ability to self-regenerate. It is this cell population that are responsible for the initiation and propagation of a tumour, and recurrence of disease following resistance to chemo and/or radiotherapy. If we can robustly target the bulk of the tumour in addition to any residual cancer stem cells then we can potentially circumvent progression and indeed recurrence of disease.

Ovarian cancer is one of the top ten most common cancers in women and is associated with a poor prognosis, primarily due to the late presentation of disease. In the coming months, the next stage in the clinical trial of ALM201 will involve the treatment of a cohort of ovarian cancer patients. Recent, unpublished preclinical data in the Robson group has indicated promising anti-cancer stem cell efficacy of ALM201 in the ovarian cancer setting. I am interested in understanding the molecular mechanisms that underpin this observed anti-cancer stem cell activity of ALM201. A new phase of academic research funding from ALMAC Discovery will enable us to carry out this work. While the specific targeting of ovarian cancer stem cells is a relatively new research field, it has potential to provide much needed alternate treatment options for this aggressive tumour type and may have implications for other malignancies.

It’s great to be part of MCT at RCSI and I’m looking forward to sharing our research findings as the project develops.
