EUSA Pharma Receive Positive Opinion from The CHMP For tivozanib For The First-Line Treatment of Advanced Renal Cell Carcinoma In The European Union
The CHMP’s recommendation is based on data from the global, open-label, randomised, multi-centre Phase III trial (TiVO-1)1,5 which evaluated the efficacy and tolerability of tivozanib compared to a currently available comparator VEGFR-TKI treatment (sorafenib) in the treatment of over 500 patients with advanced RCC. The trial met its primary endpoint demonstrating the longest median progression-free survival (PFS) seen with a VEGFR-TKI in a first-line phase III clinical study in advanced RCC. Patients treated with tivozanib experienced superior PFS (11.9 vs. 9.1 months in the overall population [HR, 0.797; 95% CI, 0.639 to 0.993; P =.042] and 12.7 vs. 9.1 months in treatment-naïve patients [HR, 0.756; 95% CI, 0.580 to 0.985; P =.037]) versus sorafenib.1,5 There was also an improved side effect profile with tivozanib, meaning 86% of patients were able to remain on full dose (versus 57% with sorafenib, P = <0.001), with only 14% (versus 43% with sorafenib) requiring a dose reduction due to adverse events (AEs). In addition, fewer people on tivozanib experienced the burdensome side effects, commonly associated with other VEGFR-TKIs, such as diarrhoea (23% vs 33%), and hand-foot syndrome (14% vs 54%).5
Dr Bernard Escudier, Medical Oncologist and member of the Genitourinary Tumour Board of Gustave Roussy, France, commented “This is excellent news for patients with metastatic RCC. Outcomes in this disease have greatly improved with the introduction of targeted therapies, meaning that patients are living for longer, although currently available therapies can be associated with burdensome toxicities. We are still in need of effective and well tolerated new treatments in metastatic RCC and thus, tivozanib will be a welcomed addition. We also look forward to continuing our investigations of potential combination approaches with other therapeutic agents.”
Tivozanib is an oral, once-daily, potent and highly-selective VEGFR-TKI. Current first-line VEGFR-TKIs block the action of a broad range of Tyrosine Kinases (TKs), in addition to the VEGFR targets, which can lead to patients experiencing burdensome side effects.5,6
“Today’s opinion by the CHMP to recommend marketing authorisation of tivozanib in the EU is an important step in expanding treatment options for patients with advanced renal cell carcinoma, where, despite advancements in therapy, survival rates in advanced disease remain low and existing treatments can be associated with therapy-limiting toxicities,” said Dr Jon Morgan, Medical Director, EUSA Pharma. “The opinion is supported by robust and consistent results from the TiVO-1 pivotal study which demonstrated compelling efficacy of tivozanib as a first-line treatment, and importantly for this class of agents, a highly favourable and advantageous tolerability profile.”
Lee Morley, EUSA Pharma’s Chief Executive Officer said, “Tivozanib has the potential to become an important new first-line therapy and this positive CHMP outcome represents a great achievement for the EUSA team. Along with the recent EU approval of dinutuximab beta, EUSA is making great strides in building a leading specialty pharmaceutical business. In our short history we have made significant progress in expanding our portfolio of specialist medicines, and we look forward to further strengthening our portfolio focused in the oncology field.”
Following the CHMP positive opinion, the European Commission will now issue a formal decision on approval, and if approved, tivozanib will be indicated for use in the 28 countries in the European Union plus Iceland and Norway.
NOTES TO EDITORS
About tivozanib and renal cell carcinoma (RCC)
Kidney cancer is the seventh most common cancer in Europe, with more than 115,000 new cases diagnosed each year.7 RCC is the most common form of kidney cancer2 with RCC accounting for around 80% of all kidney cancers.8 Kidney cancer is expected to be one of the fastest increasing cancers over the next ten years, as a result of Europe’s ageing population, with smoking and a rise in obesity also playing a part.4
An over-expression of VEGF protein, and a resulting increase in tumour blood supply (angiogenesis), is a common feature of RCC.5 VEGFR-TKIs reduce the supply of blood to the tumour and are the gold standard first-line treatment for advanced RCC in Europe, however, patients on current treatments often experience significant side effects, including skin rashes, diarrhoea, and hand-foot syndrome.
In the global Phase III trial (TiVO-1)5 in advanced RCC, tivozanib demonstrated a significant PFS benefit versus sorafenib (11.9 vs. 9.1 months in the overall patient population [HR, 0.797; 95% CI, 0.639 to 0.993; P =.042], and 12.7 vs. 9.1 months in treatment-naïve patients [HR, 0.756; 95% CI, 0.580 to 0.985; P =.037]).1,5 There was also an improved side-effect profile versus sorafenib, with significantly fewer patients on tivozanib (14% versus 43%) requiring a dose reduction due to AEs; and less than 5% of patients experiencing the severe side effects (grade 3&4) commonly associated with other VEGF-TKIs, such as diarrhoea, asthenia (physical weakness) and hand-foot syndrome. Hypertension (44%) and dysphonia (21%) were the most commonly reported AEs on tivozanib.5
Under EUSA’s license agreement with AVEO PHARMACEUTICALS, INC, announced in December 2015, the company holds exclusive commercialisation rights to tivozanib in RCC in Europe and in a number of other territories outside North America, including South America and South Africa, in addition to a range of further indications. Under the terms of the agreement, EUSA Pharma will undertake and fund the commercialisation of the product in its territories, assuming approval. AVEO PHARMACEUTICALS, INC retains the rights to commercialise the product in North America.
