A study, published in the Journal of Clinical Oncology, looked at a new precision medicine, berzosertib, in 40 patients with cancer.
Dr Darius Widera, Associate Professor in Stem Cell Biology and Regenerative Medicine, University of Reading, School of Pharmacy, said:
“This is an encouraging study providing additional evidence for the idea that blocking key players in tumour DNA repair is safe and could be used as a potent cancer treatment.
“However, as an open label phase 1 trial, this study involved only small numbers of patients and did not include a placebo control. In contrast to phase 2 and phase 3 trials, phase 1 trails are mainly are conducted with limited number of study participants and designed and to assess the safety profile of a drug rather than its efficacy. Therefore, it is too early to consider berzosertib a game changer in cancer treatment.
“Nevertheless, the unusually strong effects of berzosertib, especially in combination with conventional chemotherapy, give reasons to be optimistic regarding the outcomes of follow-up studies with larger patient numbers and appropriate placebo controls.”
‘Phase I trial of first-in-class ATR inhibitor M6620 (VX-970) as monotherapy or in combination with carboplatin in patients with advanced solid tumors’ by Timothy A. Yap et al. was published in the Journal of Clinical Oncology at 21:00 UK time on Monday 22 June 2020.
