More than 20 years of passionate drug development
Oncopeptides AB (publ) was formed in year 2000 by some of Sweden’s leading cancer researchers and cancer research institutions. More than 20 years later the Company is dedicated to providing patient access to its innovative alkylating drug.
Development of melflufen
The development of melflufen, stems from work originally undertaken by Dr Joachim Gullbo at Uppsala University, Sweden, on a molecule initially known as ‘J1’. Backed by funding from a leading venture capital firm, Industrifonden, and the Karolinska Institute, Oncopeptides embarked on a pre-clinical development journey.
Research collaboration in the US
Following an early study of the effectiveness of ‘J1’ in solid tumors, further work resulted in the development of melflufen. During this period, Oncopeptides established a research collaboration with the Harvard Medical School, Dana Farber Cancer Institute in the USA, a collaboration that has been instrumental to the development of melflufen.
Oncopeptides embarked on the phase 1/2 studies of melflufen in patients with late-stage multiple myeloma. These studies were financed by life sciences venture capital fund HealthCap, and Industrifonden together with members of the Board and Management.
Following the completion of the phase 1 of the phase 1/2 study in 2015, melflufen was granted Orphan Drug Designation in the US and EU, including extended marketing exclusivity.
Advancement of the Clinical Development Program
In 2016 the clinical research and regulatory engagement advanced. The phase 2 part of the phase 1/2 study was presented at the European Hematology Association Congress and several meetings were held with the US Food and Drug Administration (FDA) and European authorities. The design of the phase 3 study was approved by FDA through a Special Protocol Assessment process.
2022 – Making a difference for the patients
- The phase 3 OCEAN study is published in the Lancet Haematology
- Oncopeptides rescinds the voluntary withdrawal of Pepaxto in the US, based on additional analyses of survival data from OCEAN and other relevant studies
- CHMP issues a positive opinion recommending a full European approval of Pepaxti in combination with dexamethasone in triple class refractory multiple myeloma
- Oncopeptides carries out a directed share issue of approximately 435.6 million SEK
- The EU Commission approves Pepaxti for treatment of patients with relapsed refractory multiple myeloma
- FDA arranges a public hearing with the Oncologic Drugs Advisory Committee, ODAC. Most panel members state that OCEAN does not confirm a favorable benefit-risk profile in the current US indication
- Commercialization of Pepaxti in Europe is initiated, with Germany being the first market
- Clinical value of melflufen further confirmed through phase 3 LIGHTHOUSE study
- Market potential of Pepaxti in Europe I estimated to 1.5-2.0 Billion SEK
- Pepaxti is granted marketing authorization by MHRA in the UK
- Company enters into a renewed loan facility agreement of up to 30 million euro with the European Investment Bank
- FDA requests a withdrawal of the marketing authorization of Pepaxto in the US
2021 – Science is leading the way
- On February 26, FDA granted Pepaxto plus dexamethasone accelerated approval for the treatment of adult patients with relapsed or refractory multiple myeloma, who have received at least four prior lines of therapy and whose disease is refractory to at least one proteasome inhibitor, one immunomodulatory agent, and one CD38-directed monoclonal antibody.
- A European business unit was established to prepare the commercialization of melflufen in EU, and in addition an Early Access Program was initiated to provide patients with no or limited treatment options early access to melflufen.
- Oncopeptides applied to the European Medicines Agency, EMA, for conditional marketing authorization of melflufen in the EU, based on the pivotal phase 2 HORIZON study in relapsed refractory multiple myeloma.
- Results from the phase 3 OCEAN study was published. Melflufen met the primary endpoint of superior progression free survival (PFS) in a head-to-head comparison with pomalidomide. However, the overall survival (OS) HR was 1.10 in favour of pomalidomide in the Intention to Treat population.
- Based on the worse OS data, the FDA requested a partial clinical hold of all clinical studies, which means pausing the enrollment of new patients. The FDA also issued a safety alert for Pepaxto and announced a public advisory expert meeting (ODAC) to discuss the future of Pepaxto.
- On October 22, the company decided to withdraw Pepaxto from the US market and return to being a Sweden based R&D company, dedicated to further develop the proprietary PDC platform.
- Consequently, a significant part of the clinical development program for melflufen was discontinued, the commercial business units in the US and Europe were closed and the Stockholm based organization was significantly reduced.
- The application to the European Medicines Agency, EMA, for a potential Marketing Authorization of melflufen in the EU will proceed.
