Two new medicines recommended for approval

EMA’s human medicines committee (CHMP) recommended two medicines for approval at its May 2023 meeting.

The committee recommended granting a marketing authorisation for Pylclari (piflufolastat (18F)), intended for the diagnosis of prostate cancer. The benefit of this medicinal product is its potential to diagnose prostate cancer during primary staging of patients at high risk and in the staging of patients with a suspected recurrence.

Ztalmy* (ganaxolone) received a positive opinion from the CHMP for the treatment of epileptic seizures associated with cyclin-dependent kinase-like 5 deficiency disorder, a genetic disorder defined by seizures beginning in infancy.

Recommendations on extensions of therapeutic indication for two medicines

The committee recommended two extensions of indication for medicines that are already authorised in the EU: Opdivo and Sogroya*.


Following a re-examination, the CHMP confirmed its original recommendation to refuse the granting of a marketing authorisation for Sohonos* (palovarotene). This medicine was intended to treat fibrodysplasia ossificans progressiva, a rare genetic disease that causes extra bone to form in places outside the skeleton, such as in joints, muscles, tendons and ligaments, leading to progressively decreasing mobility and other severe impairments. For more information on this re-examination opinion, see the question-and-answer document in the grid below.

Withdrawals of applications

Two applications for marketing authorisation were withdrawn: Asimtufii, as a maintenance treatment of schizophrenia, and Susvimo, for the treatment of neovascular age-related macular degeneration in adults.

Question-and-answer documents on the withdrawals are available in the grid below.

Outcome of referral

The committee has recommended that Adakveo (crizanlizumab) should no longer be used to prevent painful crises in patients aged 16 years and older with sickle cell disease, a genetic condition in which the red blood cells become rigid and sticky and change from being disc-shaped to being crescent-shaped (like a sickle). This follows a review by the CHMP, which concluded that the benefits of the medicine did not outweigh its risks. The review looked at results of a clinical trial study, which compared the effectiveness and safety of Adakveo with placebo (a dummy treatment) in patients who had previously had painful crises leading to a healthcare visit. The study showed that Adakveo did not lead to a decrease when compared to the placebo. For more information, see the public health communication in the grid below.

Agenda and minutes

The agenda of the May 2023 CHMP meeting is published on EMA's website. Minutes of the April 2023 CHMP meeting will be published in the coming weeks.

*This product was designated as an orphan medicine during its development. Orphan designations are reviewed by EMA's Committee for Orphan Medicinal Products (COMP) at the time of approval to determine whether the information available to date allows maintaining the medicine’s orphan status and granting the medicine ten years of market exclusivity.
