Given its favorable risk-benefit and convenience profile, however, ponesimod might become a leading option among S1P receptor modulators used for RMS. Published peer-reviewed data on long-term safety and efficacy are still lacking but have been collected and regulatory authorities expressed a favorable opinion to market access.

Acute myeloid leukemia (AML) is the most common type of acute leukemia in adults, but the results for patients with AML are still unsatisfactory. The discovery of new mutations in AML, including IDH mutations, has opened the door for treatment with targeted agents. Ivosidenib is a selective, potent inhibitor of the IDH1 mutant protein. This review summarizes the mechanism of action, safety profile and efficacy of ivosidenib for patients with IDH1-mutated AML. The authors then provide their expert perspectives on the use of the drug including their future perspectives. Ivosidenib is a promising, most probably practice changing, new drug for the treatment of IDH1-mutated AML. Current phase III trials are ongoing to evaluate the addition of ivosidenib to the current standards-of-care. In the near future, more drug combinations are awaited. Challenges for the future include the development of resistance and establishing the duration of maintenance therapy. Ivosidenib is a promising, most probably practice changing, new drug for the treatment of IDH1-mutated AML. Current phase III trials are
