Servier Highlights Growing Neuro-Oncology Portfolio with New Data Across Pediatric and Adult Glioma at SNO 2026

PR Newswire

BOSTON, Nov. 6, 2026

• Updated results from the four-year follow-up analysis of the Phase 2 FIREFLY-1 study provide additional information on the duration of response to OJEMDA® (tovorafenib) in patients with relapsed or refractory BRAF-altered pediatric low-grade glioma
• Breadth of clinical and real-world data expands understanding of VORANIGO® (vorasidenib) in IDH-mutant glioma, including long-term outcomes and experiences across patient populations

BOSTON, Nov. 6, 2026 /PRNewswire/ -- Servier today announced that it will present nine abstracts, including five oral presentations, at the 31st Society for Neuro-Oncology (SNO) Annual Meeting, November 12-15 in Philadelphia. The data span Servier's growing glioma portfolio and include clinical and real-world data for VORANIGO® (vorasidenib) in IDH-mutant glioma, as well as recently released four-year data from the Phase 2 FIREFLY-1 study of OJEMDA® (tovorafenib) in relapsed or refractory BRAF-altered pediatric low-grade glioma (pLGG).

"By expanding the scope of clinical and real-world evidence supporting the safety and efficacy of VORANIGO and OJEMDA, we are deepening our understanding of these complex diseases and generating insights that will help us deliver meaningful treatment advances for people living with glioma," said Islam Hassan, M.D., MSc., Global Head of Development, Neuro-Oncology at Servier. "Our robust body of data at SNO underscores Servier's leadership in glioma and our commitment to advancing targeted therapies for adults and children living with significant unmet needs."

Evaluating long-term outcomes in pLGG

An oral presentation will highlight OJEMDA data in pLGG:

• Updated results from the four-year follow-up analysis of the Phase 2 FIREFLY-1 study will be presented, including data on post-treatment observation and retreatment with OJEMDA following disease progression in patients with relapsed or refractory BRAF-altered pLGG.

Building on the clinical evidence in IDH-mutant glioma

Two oral presentations will feature analyses from the Phase 3 INDIGO trial:

• Extended follow-up (median overall duration of 41.6 months) data from patients with Grade 2 IDH-mutant glioma randomized to receive VORANIGO, including subgroup analyses of histological subtype, will be presented. The results demonstrate sustained, long-term clinical benefits of VORANIGO in Grade 2 IDH-mutant glioma regardless of prognostic factors.
• A separate analysis suggests long-term treatment with VORANIGO generally led to a sustained decrease in seizure activity and delayed worsening of quality of life in patients with IDH-mutant glioma.

Exploring potential beyond the INDIGO population

Two oral presentations will highlight retrospective observational analyses of real-world utilization of VORANIGO in Grade 2 and Grade 3 IDH-mutant glioma:

• Analyses of time to next intervention (TTNI) among 499 patients with Grade 2 IDH-mutant glioma demonstrated short-term real-world effectiveness of VORANIGO. The highest rate was observed among frontline VORANIGO users. 
• An analysis of a cohort of 80 Grade 3 mIDH glioma patients showed emerging evidence of the effectiveness of VORANIGO in these patients.

These data collectively reflect Servier's continued investment in advancing glioma research. A full list of Servier abstracts and presentation details for SNO 2026 can be found here.

About Glioma1
Gliomas are tumors that arise from glial or precursor cells within the central nervous system (CNS). The 2021 World Health Organization (WHO) classification recognizes four general groups of gliomas, one of which is adult-type diffuse gliomas. These diffuse gliomas are the most common primary malignant brain tumors in adults. The pathogenesis and prognosis of these tumors are tightly linked to mutations (or lack thereof) in the metabolic enzyme isocitrate dehydrogenase (IDH), and molecular testing is required for proper diagnosis. As of 2021, adult-type diffuse gliomas are sub-divided into only three categories:

• Astrocytoma, IDH-mutant (CNS WHO grades 2-4)
  
  
• Oligodendroglioma, IDH-mutant and1p/19q-codeleted (CNS WHO grades 2-3)
  
  
• Glioblastoma, IDH-wildtype (CNS WHO grade 4)

About Pediatric Low-Grade Glioma

Pediatric low-grade gliomas (pLGG) are the most common brain tumor with an estimated US incidence of 1,100 and Europe incidence of 700 children per year who are eligible for front-line systemic therapy.2, 3 BRAF is the gene most commonly altered in pLGG, which includes two primary types of BRAF alterations – a BRAF gene fusion and BRAF point mutation. These BRAF alterations account for >50% of pLGG cases worldwide and prior to the introduction of OJEMDA, there were no approved treatments for people with pLGG driven by BRAF fusions.2, 4

Pediatric low-grade gliomas can be chronic and relentless, with patients suffering profound side effects from both the tumor and the treatment, which may include chemotherapy and radiation. These side effects can impact their life over the long term, and may include motor deficiencies, vision loss, hormone deficiency and alterations in growth and development. Most children with pLGG will survive their cancer, but for the majority of those in whom a complete surgical resection is not possible, these tumors tend to recur frequently throughout childhood, necessitating multiple treatments. The cumulative toxicity of numerous therapies, along with the damage caused by multiple episodes of tumor progression, take a significant toll on the children and their families.

VORANIGO IMPORTANT SAFETY INFORMATION

What is VORANIGO?

VORANIGO (40 mg tablets) is a prescription medicine used to treat adults and children 12 years of age and older with certain types of brain tumors called astrocytoma or oligodendroglioma with an isocitrate dehydrogenase-1 (IDH1) or isocitrate dehydrogenase-2 (IDH2) mutation, following surgery. Your healthcare provider will perform a test to make sure that VORANIGO is right for you. It is not known if VORANIGO is safe and effective in children under 12 years of age.

What are the possible side effects of VORANIGO?

VORANIGO may cause serious side effects, including:

• Liver problems. Changes in liver function blood tests may happen during treatment with VORANIGO and can be serious.

OJEMDA INDICATION and IMPORTANT SAFETY INFORMATION

WHAT IS OJEMDA® (tovorafenib)? 

OJEMDA is a prescription medicine used to treat a type of brain tumor (cancer) called pediatric low-grade glioma (pLGG) in people 6 months of age and older whose tumor has come back after previous treatment or did not respond to previous treatment, and that has a certain type of abnormal BRAF gene. A healthcare provider will perform a test to confirm that OJEMDA is right for the patient.

OJEMDA was approved based on how many patients' tumors responded to treatment and how long those responses lasted. Continued approval may depend on confirmation of clinical benefit in a confirmatory study. It is not known if OJEMDA is safe and effective in children younger than 6 months of age.

IMPORTANT SAFETY INFORMATION

OJEMDA may cause serious side effects, including:

• Bleeding problems (hemorrhage). Bleeding is common during treatment with OJEMDA and can also be serious. Patients should contact their healthcare provider or get medical help right away if they have any signs of bleeding, such as headache, dizziness or weakness, coughing up or vomiting blood (or vomit that looks like coffee grounds), or red or black stools that look like tar.
• Skin reactions, including sensitivity to sunlight (photosensitivity). OJEMDA can cause skin reactions that may become severe. Patients should tell their healthcare provider about new or worsening skin reactions, such as rash, acne, bumps, blisters, or peeling, redness, or irritation. Patients should limit time in sunlight and use sun protection, such as sunscreen, sunglasses, and protective clothing, during treatment.
• Liver problems. OJEMDA can cause liver problems. A healthcare provider will do blood tests to check the liver before and during treatment. Patients should tell their healthcare provider right away about yellowing of the skin or the whites of the eyes, dark or brown (tea-colored) urine, nausea or vomiting, loss of appetite, feeling tired, bruising, bleeding, or pain in the upper right stomach area.
• Slowed growth in children. OJEMDA can slow growth in children. A child's growth will be checked routinely during treatment with OJEMDA.
• Harm to an unborn baby. OJEMDA can harm an unborn baby. A healthcare provider will check whether a patient is pregnant before starting OJEMDA. Females who are able to become pregnant should use effective nonhormonal birth control during treatment and for 28 days after the last dose, because OJEMDA can cause some hormonal birth control to not work as well. Males with female partners who are able to become pregnant should use effective birth control during treatment and for 2 weeks after the last dose. Patients should tell their healthcare provider right away if they become pregnant or think they might be pregnant during treatment.

Before receiving OJEMDA, patients should tell their healthcare provider:

• about all of their medical conditions, including if they have bleeding, skin, or liver problems; or are pregnant, plan to become pregnant, or are breastfeeding.
• about all the medicines they take, including prescription and over-the-counter medicines, vitamins, herbal supplements, and any hormonal birth control. OJEMDA may affect how other medicines work, and other medicines may affect how OJEMDA works.

Patients should not breastfeed during treatment with OJEMDA and for 2 weeks after the last dose.

OJEMDA may cause fertility problems in males and females, which may affect the ability to have children.

The most common side effects of OJEMDA include rash, hair color changes, feeling tired, viral infection, vomiting, headache, bleeding, fever, dry skin, constipation, nausea, acne, and upper respiratory tract infection.

The most common severe abnormal blood test results include decreased phosphate, decreased red and white blood cells, increased creatine phosphokinase, increased liver function tests, decreased albumin, decreased potassium, and decreased sodium.

These are not all of the possible side effects of OJEMDA. Talk to a healthcare provider for medical advice about side effects.
