Background:

Lurbinectedin (PM01183) is a new DNA minor groove covalent binder with potent anti-tumour activity; inhibits RMG1 and RMG2 cell growth with IC50 values of 1.25 and 1.16 nM, respectively.

PM01183 is a new synthetic tetrahydroisoquinoline alkaloid that is currently in phase I clinical development for the treatment of solid tumours. PM01183-DNA adducts in living cells give rise to double-strand breaks, triggering S-phase accumulation and apoptosis. The potent cytotoxic activity of PM01183 is ascertained in a 23-cell line panel with a mean GI50 value of 2.7 nM[2]. Lurbinectedin exhibits significant antitumor activity toward chemosensitive and chemoresistant human ovarian clear cell carcinoma (CCC) cells in vitro[1].

Mouse CCC cell xenografts reveals that lurbinectedin significantly inhibits tumor growth. Lurbinectedin plus SN-38 results in a significant synergistic effect[1]. In four murine xenograft models of human cancer, PM01183 inhibits tumour growth significantly with no weight loss of treated animals[2]. Single lurbinectedin or cisplatin-combined therapies are effective in treating cisplatin-sensitive and cisplatin-resistant preclinical ovarian tumor models. The strongest synergistic effect is observed for combined treatments, especially in cisplatin-resistant tumors. Lurbinectedin tumor growth inhibition is associated with reduced proliferation, increased rate of aberrant mitosis, and subsequent induced apoptosis[3].
