(Reuters) - Abbvie Inc on Friday said bit.ly/2F9iUlb it will record an estimated $4 billion in impairment charges related to the scrapping of its development program of Rova-T, an investigational cancer therapy.

The drugmaker acquired Rova-T through its $5.8 billion acquisition of Stemcentrx in 2016, as it aimed to enter the broad and lucrative arena of solid tumors and lessen dependence on its blockbuster arthritis treatment Humira.

In December, Abbvie halted enrollment for a late-stage trial of Rova-T as a second-line therapy for advanced small-cell lung cancer, following recommendations made by an independent data monitoring committee.

Abbive said it will monitor a remaining $1 billion of intangible assets for further impairment. It added that it will continue to evaluate other Stemcentrx-related clinical development programs.
