QBiotics receives first registration for tigilanol tiglate with European Medicines Agency approval of Stelfonta(R)
BRISBANE, Australia, Jan. 20, 2020 /PRNewswire-AsiaNet/ --

- STELFONTA(R) (tigilanol tiglate) approved by the European Medicines Agency 
(EMA), making it the first pharmaceutical treatment available for all grades of 
canine non-metastatic mast cell tumours (MCT)[1] 
- The approval marks the first registration of QBiotic's, lead compound 
tigilanol tiglate, which is also under review by the US Food and Drug 
Administration - Center for Veterinary Medicine (FDA-CVM) and the Australian 
Pesticides and Veterinary Medicines Authority (APVMA); 
- Approval is supported by a full technical data package focused on safety and 
efficacy including a pivotal study in 123 canine patients where a single 
injection of STELFONTA(R) completely removed (Complete Response) 75% of treated 
MCT;[2] 
- QBiotics have partnered with Virbac, who will be launching STELFONTA(R) 
across key EU markets in the coming months. 

Australian life sciences company, QBiotics Group Limited (QBiotics) is today 
announcing the first registration for its small molecule, tigilanol tiglate, 
with the European Medicines Agency (EMA) approval of STELFONTA as an oncology 
veterinary pharmaceutical.

QBiotic's STELFONTA receives EMA approval

STELFONTA (tigilanol tiglate) is indicated for the treatment of non-resectable, 
non-metastatic (WHO staging[3]) subcutaneous MCT located at or distal to the 
elbow or the hock, and non-resectable, non-metastatic cutaneous MCT in dogs. 
Tumours must be less than or equal to 8 cm[3] in volume and must be accessible 
to intratumoural injection.[1]

MCTs are the second most frequent cancer diagnosed in dogs and the most common 
skin cancer, accounting for up to 21% of skin cancer cases.[3]

QBiotics Veterinary Oncologist, Dr Pam Jones said, "The EMA approval of 
STELFONTA represents an exciting additional treatment option for MCT where 
surgical removal of the tumour mass is currently the standard of care.[4] 
However, there are some challenges associated with surgery, as in some cases 
the tumour isn't always easily accessible, and anaesthesia carries inherent 
risks - especially for older dogs and brachycephalic breeds."

"STELFONTA is administered by injection directly into the tumour mass. 
Generally, dogs undergoing treatment do not need to be sedated, or need local 
or general anaesthesia," said Dr Jones. 

Worldwide, as many as 1 in 4 dogs will develop cancer at some time in their 
lives. Cancer is the leading cause of death in dogs, with almost 50% of dogs 
over the age of 10 years dying of the disease.[5,6]  

"To date, there are only a very small number of registered treatments for 
cancer in companion animals, providing a significant opportunity for new 
treatments in this growing market," said QBiotics' CEO and Managing Director, 
Dr Victoria Gordon.

"Tigilanol tiglate is a new approach to the problem of cancer. The drug works 
largely through specific protein kinase C (PKC) activation, in which it locally 
stimulates the immune system, resulting in destruction of the tumour mass and 
the tumour's blood supply, followed by rapid healing of the site with minimal 
scarring,"[7] Dr Gordon said.

Approval for STELFONTA was based on a full data package supporting the safety 
and efficacy of STELFONTA. This included a QBiotics sponsored, pivotal, multi 
centre, randomised, blinded and untreated control study in 123 canine patients 
with MCTs. This study was conducted in accordance with the principles of Good 
Clinical Practice (GCP) as outlined in 'Guidance for Industry Guideline #85 of 
the USA Food and Drug Administration (FDA), Center for Veterinary Medicine Good 
Clinical Practice: VICH GL9, Final Guidance May 2001.

In this pivotal study conducted in eleven veterinary clinics, at 28 days post 
treatment 75% percent of dogs achieved a Complete Response (tumour is 
completely destroyed) after a single intra-tumoural injection of STELFONTA 
compared to untreated controls (p=0.0001). Importantly, STELFONTA(R) was very 
well tolerated and animals had a good quality of life during and after 
treatment.[2]   

Dr Gordon said "QBiotics and our partner, global veterinary pharma company 
Virbac, are gearing up for the launch of STELFONTA in early 2020, initially in 
the UK, France, Spain and Germany, and later in the USA, subject to FDA 
approval. This is an exciting time for QBiotics, adding global 
commercialisation of a novel pharmaceutical to our list of attributes."
