- Rozlytrek has shown durable responses across multiple tumour types, including cancer that has spread to the brain
- This approval shows the value of combining genomic profiling with precision medicine to offer patients with rare and hard-to-treat cancers a personalised treatment option
Basel, 03 August 2020 – Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced that the European Commission has granted conditional marketing authorisation for Rozlytrek® (entrectinib) for the treatment of adult and paediatric patients 12 years of age and older with solid tumours expressing a neurotrophic tyrosine receptor kinase (NTRK) gene fusion, who have a disease that is locally advanced, metastatic or where surgical resection is likely to result in severe morbidity, and who have not received a prior NTRK inhibitor, who have no satisfactory treatment options. The European Commission has also approved Rozlytrek for the treatment of adults with ROS1-positive, advanced non-small cell lung cancer (NSCLC) not previously treated with ROS1 inhibitors.1
“We are excited to announce the approval of Rozlytrek in Europe for two indications, bringing patients with NTRK and ROS1 gene fusions a new effective treatment even when their cancer has spread to the brain,” said Levi Garraway, M.D., Ph.D., Roche’s Chief Medical Officer and Head of Global Product Development. “This advance represents another important step forward in cancer care by allowing us to treat certain genetic drivers of cancer irrespective of the location of the tumour within the body. Roche is deeply committed to driving personalised healthcare and addressing the high unmet need in patients around the world with rare cancers.”
The approval is based on results from the integrated analysis of the pivotal phase II STARTRK-2, phase I STARTRK-1 and phase I ALKA-372-001 trials, and data from the phase I/II STARTRK-NG study. These studies demonstrate that Rozlytrek has durable responses across several NTRK gene fusion-positive solid tumours, including sarcoma, non-small cell lung, salivary MASC, secretory and non-secretory breast, thyroid, colorectal, neuroendocrine, pancreatic, ovarian, endometrial carcinoma, cholangiocarcinoma, gastrointestinal cancers and neuroblastoma, as well as ROS1-positive NSCLC.1 Results showed:
- Rozlytrek shrank tumours in more than half of people with NTRK fusion-positive, locally advanced or metastatic solid tumours (overall response rate [ORR]=63.5%; N=74), and objective responses were observed across 14 tumour types (median duration of response [DoR]=12.9 months [9.3 months – not reached], N=21 out of 47 patients defined by ORR).1
- In ROS1-positive, advanced NSCLC, Rozlytrek shrank tumours in 73.4% of people with the disease (ORR; N=94 with a minimum of 12 months follow up), with a median DoR of 16.5 months (14.6 – 28.6 months). In a group of 161 patients with a minimum of 6 months follow up, including 29% of patients with central nervous system (CNS) metastases at baseline, ORR was observed to be 67.1%.1
- Objective responses to Rozlytrek were seen in people with CNS metastases at baseline, with an intracranial ORR of 62.5% and 77.8% in both NTRK and ROS1 populations, respectively.1
- In paediatric patients, Rozlytrek shrank tumours (ORR) in all children and adolescents who had NTRK gene fusions (N=5), with two achieving a complete response (CR). Two patients with primary high-grade tumours in the CNS had objective responses, including one patient with a CR.1 Rozlytrek was well tolerated.
- The most common adverse reactions (≥20 percent) with Rozlytrek were fatigue, constipation, altered sense of taste (dysgeusia), swelling (oedema), dizziness, diarrhoea, nausea, nervous system disorders (dysaesthesia), shortness of breath (dyspnoea), anaemia, increased weight, increased blood creatinine, pain, cognitive disorders, vomiting, cough, and fever (pyrexia).1
Rozlytrek has been granted Priority Medicines (PRIME) designation by the EMA for the treatment of NTRK fusion-positive, locally advanced or metastatic solid tumours in adult and paediatric patients who have either progressed following prior therapies or who have no acceptable standard therapies.1 NTRK gene fusions have been identified in a range of solid tumour types, and are present in up to 90% of some rare cancer types and less than 1% of other more common tumours, including lung and colorectal.2 ROS1 gene fusions account for 1-2% of NSCLC, the most common type of lung cancer that accounts for up to 85% of all diagnoses.3,4
Biomarker testing for these fusions is the most effective way to identify people who are most eligible for treatment with Rozlytrek. Roche is leveraging its expertise in developing personalised medicines and advanced diagnostics, in conjunction with Foundation Medicine, to develop a companion diagnostic that will help identify people with NTRK and ROS1 gene fusions.
About the integrated analysis
The approval in Europe is based on an integrated analysis including data from 74 people with locally advanced or metastatic NTRK fusion-positive solid tumours (14 tumour types) and 161 people with ROS1-positive NSCLC from the phase II STARTRK-2, phase I STARTRK-1 and phase I ALKA-372-001 trials.1 It is also based on data from the phase I/II STARTRK-NG study in paediatric patients. The studies enrolled people across 15 countries and more than 150 clinical trial sites. Safety was assessed from an integrated analysis of 504 people across these four trials.1
About NTRK fusion-positive cancer
NTRK fusion-positive cancer occurs when the NTRK1/2/3 genes fuse with other genes, resulting in altered TRK proteins (TRKA/TRKB/TRKC) that can activate signalling pathways involved in the proliferation of certain types of cancer.5 NTRK gene fusions are present in tumours irrespective of site of origin. These fusions have been identified in a broad range of solid tumour types, including sarcoma, non-small cell lung, salivary MASC, secretory and non-secretory breast, thyroid, colorectal, neuroendocrine, pancreatic, ovarian, endometrial carcinoma, cholangiocarcinoma, gastrointestinal cancers and neuroblastoma.1
About ROS1-positive NSCLC
ROS1 is a tyrosine kinase, which plays a role in controlling how cells grow and proliferate. When a ROS1 gene fusion occurs, cancer cells grow and proliferate in an uncontrolled manner. Blocking this abnormal signalling can cause tumour cells to shrink or die.3
ROS1 gene fusions account for 1-2% of NSCLC.3 Lung cancer is the leading cause of cancer-related death across the world.6 Each year, more than one and a half million people die as a result of the disease globally, equating to more than 4,000 deaths every day.6 NSCLC is the most common type of lung cancer and accounts for up to 85% of all lung cancer diagnoses.4 While the ROS1 gene fusion can be found in any patient with NSCLC, young never-smokers with NSCLC have the highest incidence of ROS1 gene fusions.3
About Rozlytrek
Rozlytrek® (entrectinib) is a tumour-agnostic once-daily oral medicine for the treatment of locally advanced or metastatic solid tumours that harbour NTRK1/2/3 or ROS1 gene fusions. It is a selective tyrosine kinase inhibitor designed to inhibit the kinase activity of the TRKA/B/C and ROS1 proteins, whose activating fusions drive proliferation in certain types of cancer.7,8 Rozlytrek can block NTRK and ROS1 kinase activity and may result in the death of cancer cells with NTRK or ROS1 gene fusions.7,8
Rozlytrek was granted accelerated approval in August 2019 by the US Food and Drug Administration (FDA), following receipt of Breakthrough Therapy designation, for the treatment of adult and paediatric patients 12 years of age and older with solid tumours that have a NTRK gene fusion without a known acquired resistance mutation, are metastatic or where surgical resection is likely to result in severe morbidity, and have progressed following treatment or have no satisfactory alternative therapy, and was approved for the treatment of adults with ROS1-positive, metastatic NSCLC. In June 2019, Japan’s Ministry of Health, Labour and Welfare (MHLW) also approved Rozlytrek for the treatment of adult and paediatric patients with NTRK fusion-positive, advanced recurrent solid tumours, and later approved Rozlytrek in ROS1-positive NSCLC in February 2020. Rozlytrek has also received approvals by health authorities in Australia, Canada, Hong Kong, Israel, New Zealand, South Korea and Taiwan.
