ORPHELIA Pharma and Gustave Roussy announce issuance of European Patent covering Kimozo®, the first oral liquid formulation of temozolomide

Paris and Lyon, on June 16, 2021 – ORPHELIA Pharma, a French biopharmaceutical company dedicated to the development and marketing of pediatric and orphan drugs and Gustave Roussy, the leading cancer center in Europe, announce today that the European Patent Office has issued Patent EP3613436, which is directed to Kimozo®, the first pediatric, ready-to-use and taste-masked oral suspension of temozolomide. Kimozo® results from the collaboration between the pharmacists and clinicians from Gustave Roussy and ORPHELIA Pharma.

“Temozolomide is an essential oncology drug used to treat relapsed or refractory neuroblastoma, a disease that unfortunately affects very young children. We are working in close collaboration with European clinicians and our goal is to make this pediatric form of temozolomide available as early as 2021 through early access programs”; commented Jeremy Bastid, Chief Development Officer of ORPHELIA Pharma.

“We have developed a hospital compounded liquid preparation of temozolomide in 2015 to address the needs of young patients treated at our center”, explain Maxime Annereau, pharmacist and Samuel Abbou, pediatric oncologist at Gustave Roussy, both at the origin of this project. “This hospital formulation was suitable for children but did not exhibit the physico-chemical and stability properties compatible with an industrialized product. This product was therefore not available to all patients. Three years of research and development between Gustave Roussy and ORPHELIA Pharma were necessary in order to achieve the targeted specifications: a highly concentrated, taste-masked and stable formulation”.

“Our research efforts led to the development of Kimozo®, the first drinkable formulation of temozolomide. The innovation is based on the discovery of a key excipient involved in the stability and the control of the rheological properties of the suspension, an invention that has been patented”, concludes Jeremy Bastid.

The grant of Patent EP3613436 entitled “oral suspension of temozolomide” and co-owned by ORPHELIA Pharma and Gustave Roussy has been published in the European Patent Bulletin. Based on the filing date of the application, the patent protection is expected to last until 2038.

About Kimozo®

Kimozo® (also known as ORP-005 or Ped-TMZ) is a ready-to-use and taste-masked oral suspension of temozolomide that is currently under development to address the needs of children. Kimozo® is an investigational medicinal product not yet approved for marketing.

ORPHELIA Pharma announces the inclusion of the first patient in the TEMOkids pediatric clinical trial

Paris and Lyon, on May 4^th, 2021 – ORPHELIA Pharma, a French biopharmaceutical company dedicated to the development and marketing of pediatric and orphan drugs, announces the inclusion of a first patient in the TEMOkids pediatric clinical study. The TEMOkids study aims to determine the pharmacokinetic parameters, tolerance, acceptability and response to treatment of Kimozo®, the first oral suspension of temozolomide, in the pediatric population (www.temokids.eu).

Temozolomide is an anti-cancer drug used in treatment regimens for refractory or relapsed neuroblastoma that mainly affect very young children. It is also used to treat rhabdomyosarcoma and certain brain tumors. The only oral forms of temozolomide currently available are capsules which are not suited to children. In fact, to be administered, the capsules must be opened and their content added to food. In young children, the formulation is essential to ensure correct medication intake, safety, accuracy of the delivered dose and adherence to treatment. To meet the requirements of onco-pediatricians and the needs of children, ORPHELIA Pharma, working in close collaboration with Gustave Roussy hospital teams, has developed Kimozo®, the first ready-to-use drinkable suspension of temozolomide.

“The TEMOkids trial, during which our oral suspension of temozolomide will be administered to children for the first time, is a key stage in the clinical development of Kimozo®,” says Caroline Lemarchand, Chief Pharmaceutical Development Officer for ORPHELIA Pharma, “This study will evaluate the pharmacokinetics of temozolomide, alone or in combination with other treatments, in children from 1 year of age. It will also define the tolerance and acceptability of Kimozo® within the study population, and collect data on tumor response to treatment. The first results of this clinical trial are expected mid-2022.“

“We are very pleased to be involved in the clinical development of this long-awaited new pediatric formulation of temozolomide for the treatment of cancer in children,” says Dr Samuel Abbou, pediatric oncologist at the Gustave Roussy hospital, and coordinating investigator of the TEMOkids study. “The study plans to recruit 40 children in 5 countries; that is France, Germany, Spain, the UK and the Netherlands, thanks to the support of a structured European-scale pediatric oncology network.”

“We have received an enthusiastic response from the members of the European pediatric oncology community who have chosen to participate in this clinical trial,” says Hugues Bienaymé, General Manager and Chief Scientific Officer for ORPHELIA Pharma, before adding by way of a conclusion that “TEMOkids complements our ongoing bioequivalence study in adult patients, and should support the filing of the Kimozo® registration dossier at European level in 2023.”

About the TEMOkids study (NCT04610736)

The clinical trial entitled “TEMOkids Study: A Phase I Pediatric Study for KIMOZO, Oral Suspension of temozolomide” is an international, open-label, non-randomized, phase 1 study involving 40 pediatric patients aged 1 year and over. The main objective of this study is to determine the pharmacokinetic parameters of Kimozo® in the population concerned by the study. The secondary objectives are to evaluate its tolerance and acceptability among children, and their response to treatment.

Ten clinical centers are involved in the TEMOkids study: Gustave Roussy in Villejuif (the coordinating center); Institut Curie in Paris, France; La Timone Children’s Hospital in Marseille, France; The Institute of Pediatric Hematology and Oncology in Lyon, France; The Oscar Lambret Center in Lille, France; The Charité University Medical Hospital in Berlin, Germany; The Hopp Children’s Cancer Center in Heidelberg, Germany; The Princess Máxima Center for Pediatric Oncology in Utrecht, the Netherlands; The Vall d’Hebron Research Institute in Barcelona, Spain; and Southampton General Hospital in the United Kingdom.

ORPHELIA announces the inclusion of the first patient in a clinical study evaluating Kimozo, its pediatric formulation of temozolomide

Paris and Lyon, October 5^th, 2020 – ORPHELIA Pharma, a French biopharmaceutical company dedicated to the development and marketing of pediatric and orphan drugs is pleased to announce the inclusion of the first-in patient in a clinical study aimed at demonstrating the bioequivalence between Kimozo, the first pediatric formulation of temozolomide under clinical development, and Temodal® capsule.

Although not approved in this indication, temozolomide is an essential anticancer medicine recommended for use in treatment protocols of relapsed or refractory neuroblastoma, a condition that affects young children. However, the only oral formulations that are commercially available are in the form of capsules that are poorly adapted to children. Caretakers are thus compelled to open capsules and disperse the content into a soft food prior to administration to the child, which harbors several risks such as the uncertainty with regards to the delivered dose, the exposure of the caregiver to the cytotoxic drug and the instability of the drug in aqueous milieu. To overcome the risks this situation implies, Kimozo, a ready to use oral formulation has been specifically designed to address the needs of the pediatric population.

Kimozo has been developed in collaboration with Gustave Roussy, one of the leading cancer centers in Europe. The current clinical trial conducted by ORPHELIA Pharma aims at demonstrating, first for regulatory purposes, the bioequivalence between Kimozo and the Temodal® capsules in adult patients having brain cancers, with additional clinical investigation to come in the pediatric population of interest.

“We have reached an important milestone for Kimozo with the clinical trial approval from competent authorities and the recruitment of a first patient“, said Caroline Lemarchand, Chief Pharmaceutical Development Officer of ORPHELIA Pharma “We plan to enroll 30 patients by mid-2021 thanks to the support of the three neuro-oncology teams involved in the study: Professor Ducray of the Hospices Civils de Lyon (coordinating investigator), Professor Chinot of the Timone Hospital in Marseille and Dr Bronnimann of Saint-André Hospital in Bordeaux. ”

“We are pleased to contribute to the development of this new pediatric formulation of temozolomide. A liquid form is unambiguously of interest for treating children.“, underlines Pr. François Ducray. Hugues Bienaymé, General Manager of ORPHELIA Pharma further comments: “This first administration is a major milestone in the development of Kimozo. We are now preparing the opening of our second clinical trial, which will evaluate Kimozo in pediatric patients, by the end of the year ”, he concludes.

About the Bioequivalence Study (NCT04467346)

The clinical trial entitled “Bioequivalence Study between temozolomide oral suspension (Ped-TMZ) and Temodal® capsules” (NCT04467346) is an open label phase I study, randomized, crossover, 2-period study in 30 male/female patients with primary CNS malignancies. Patients will receive, under fasting conditions, 200 mg/m² of Temozolomide Oral Suspension (Ped-TMZ, the code name of Kimozo) or Temodal®, as single oral administration in 2 different study periods depending on the randomization, with no wash out period between administrations. The primary objective is to evaluate the bioequivalence between Kimozo and Temodal® capsules for oral administration. The secondary objectives are to define the pharmacokinetic parameters of Kimozo administration and to assess its buccal safety.

The clinical centers are Hospices Civils de Lyon, Bron, France ; CHU de Bordeaux, Bordeaux, France and Hôpital de la Timone (AP-HM), Marseille, France. The Study sponsor is ORPHELIA Pharma.
