Phase I study of triple drug combination shows promise in multiple myeloma patients

In continuation of my updates on Dexamethasone,  Plitidepsin and  Bortezomib 

PharmaMar (MSE:PHM) announces the positive results from a Phase I study of plitidepsin in combination with bortezomib and dexamethasone in patients with relapsed and/or refractory multiple myeloma. Dr María Victoria Mateos, MD of the Hematological Department of the University Hospital of Salamanca, Spain, the principal investigator of the study, will present the results in an oral session on June 3rd, 2016 during the 52nd Congress of the American Society of the Clinical Oncology (ASCO), taking place in Chicago (USA), June 3 - 7.

The primary objective of this 20-patient study was to identify the recommended dose for the triple combination (dexamethasone / bortezomib / plitidepsin) administered every four weeks. Efficacy and the safety profile were also evaluated. The overall response rate (ORR) was 56%, including very good partial responses (VGPR) in 33% of the patients and a remarkable partial remission in one triple refractory patient. The median progression free survival (PFS) was 8.3 months. Additionally, 90% of the patients showed a DOR of 6 months or more and clinical benefit was observed in 72% of the patients.

Dose limiting toxicities were not seen in any of the evaluated patients; therefore, the full dose of plitidepsin and bortezomib when used alone were established as the recommended dose for the triple combination. The treatment was well tolerated. The hematological toxicity was manageable and the non-hematological toxicity was in general mild, with the exception of one case of creatinine increase.
Out of the 20 patients that participated in the study, 10 are still under the treatment. The median age was 65. All patients had relapsed after previously receiving, on average, 3.5 therapeutic regimens (range 1-10). Forty-five percent of these patients had been subject to a hematopoietic stem cell transplant (8 autologous, 1 allogeneic). Of the 18 patients evaluable for efficacy, 83% (15 patients) had previously received bortezomib and lenalidomide. One was refractory to bortezomib and seven to lenalidomide.

In abstract #8006, Dr María Victoria Mateos and her team explain that despite the recent progress in the treatment of multiple myeloma due to the introduction of proteasome inhibitors (PIs), the new immunomodulatory drugs (IMIDs), and monoclonal antibodies, the illness is still incurable. Therefore, active compounds with novel mechanisms of action and adequate safety profile are needed. Plitidepsin targets the eukaryotic Elongation Factor eEF1A2, an overexpressed protein in multiple myeloma that contributes to its pathogenesis. The positive results from this study will be added to the already extensive data package from Phase II and Phase III trials, where plitidepsin has shown activity and a favorable safety profile in combination with dexamethasone.

STA inks license and commercialisation agreement with PharmaMar for APLIDIN (plitidepsin)

Australian biopharmaceutical company Specialised Therapeutics Australia has struck an exclusive license and commercialisation agreement with European pharmaceutical partner company PharmaMar to market and distribute the novel oncology drug APLIDIN® (plitidepsin) in Australia and New Zealand.

Under the terms of the agreement, PharmaMar will receive an upfront payment, royalties and additional remunerations for regulatory and sales milestones achieved by APLIDIN® (plitidepsin).

PharmaMar will retain production rights and will supply the finished product to STA for exclusive commercial use in Australia and New Zealand.

APLIDIN® (plitidepsin) is PharmaMar´s second anticancer drug candidate obtained from a marine organism. This first in class drug is currently in development for the treatment of multiple myeloma and a type of T cell lymphoma. The company announced in June that patient recruitment of the international pivotal Phase III trial (ADMYRE) for APLIDIN® (plitidepsin) in refractory/relapsed multiple myeloma was successfully completed.

In continuation of my updates on  dexamethasone and Aplidin (plitidepsin) 

PharmaMar (MSE:PHM)  announced positive top-line results of its Phase III clinical trial -ADMYRE- with Aplidin (plitidepsin) in combination with dexamethasone versus dexamethasone alone in patients with relapsed/refractory multiple myeloma (MM). Aplidin® has shown a statistically significant 35% reduction in the risk of progression or death over the comparator (p=0.0054). The study has met its primary endpoint.

This pivotal, randomized, open-label, international, multicenter Phase III clinical trial, called ADMYRE, enrolled 255 patients in 83 medical centers across 19 countries (including the U.S, Europe and Asia-Pacific) with relapsed or relapsed and refractory multiple myeloma after at least three but no more than six prior therapeutic regimens.

The efficacy of plitidepsin in combination with dexamethasone versus dexamethasone alone has been evaluated by means of PFS calculated using the IMWG (International Myeloma Working Group) criteria and other secondary efficacy endpoints. A full description of the final ADMYRE data will be submitted for presentation at an upcoming medical meeting.

"Taking into account these positive results, we intend to submit a Marketing Authorization Application to the European Medicines Agency during the last quarter of this year", said Luis Mora, Managing Director of the Oncology Business Unit of PharmaMar, who added "I´d like to thank all the patients, physicians and the dedicated team at PharmaMar who helped participate in the success of this trial. Aplidin® may be our second drug of marine origin in the market".

As previously disclosed PharmaMar has entered into licensing agreements to market and distribute the drug candidate Aplidin with Specialised Therapeutics Asia, covering several Asian countries, Australia and New Zealand; with TTY Biopharm in Taiwan; and with a co-promotion agreement in 8 European countries with Chugai Pharma Europe.
