belinostat / BELEODAQ®


Belinostat is a histone deacetylase inhibitor (HDACi). It has been assessed in several clinical trials as a sole treatment (monotherapy) or in combination with other anti-cancer treatments for hematological cancers and solid tumors. Its anti-cancer activity is associated with the inhibition of cell proliferation, the induction of apoptosis (programmed cell death), the inhibition of angiogenesis and the induction of cellular differentiation.

Beleodaq® is the commercial name of belinostat for injection.

In July 2014, Beleodaq® received conditional approval from the FDA for the treatment of peripheral T-cell lymphoma. This authorization was given within an accelerated registration program which conditionally approves a drug designed for the treatment of a life-threatening disease based on predictive elements of a clinical benefit. The registration is based on the results of the phase 2 BELIEF clinical trial of 129 patients suffering from peripheral T-cell lymphoma, resistant or in relapse after at least one initial systemic treatment, which showed a response level of 25% with a median duration of response of 8.3 months and a good tolerance profile. To comply with FDA requirements, a clinical phase 3 trial is required to assess the efficacy of Beleodaq® in combination with CHOP (cyclophosphamide, hydroxydaunorubicine, oncovin, and prednisone) against CHOP in the 1st line of treatment of peripheral T-cell lymphoma.

Beleodaq® benefits from industrial protection until at least 2026. Its protection is strengthened by an orphan drug designation (ODD) in Europe and the United States, which provides commercial exclusivity. Belinostat could also be developed as an oral formulation. This would enable a significant extension of the intellectual property and facilitate the use of belinostat in combination with other anti-cancer agents.

Finally, since April 2017, Beleodaq has also been made available at the request of healthcare professionals as part of a Named Patient Program (NPP) run by Clinigen (for more information on this programme, visit the "Licensing Agreements and Collaborations" section below).


Acrotech LLC

As part of a collaboration and licensing agreement entered into in 2010, Spectrum Pharmaceuticals was co‑developing Beleodaq® in partnership with Onxeo and was in charge of its promotion to oncology and hematology experts in North America and India.

On March 1, 2019, Spectrum Pharmaceuticals (SPPI) announced the completion of the sale of its seven hematology/oncology products approved by the FDA, including Beleodaq®, to Acrotech Biopharma LLC, a US subsidiary of Aurobindo Pharma.

On April 6, 2020, Onxeo granted additional exclusive rights to belinostat to Acrotech (access the related press release). The new Agreement grants Acrotech a royalty-free license to belinostat in all other territories. As part of this transaction, Onxeo’s current licensing agreement with Pint Pharma for South America, as well as the contracts for named patient programs in European countries and related agreements, described below have also been tranferred to Acrotech.

Pint Pharma

In 2016, the Company signed a licensing agreement with Pint Pharma for the registration and marketing of Beleodaq® in PTCL in several countries in Latin America.

Clinigen Group

In April 2017, Onxeo and Clinigen Group have set up a European Managed Access Program (MAP) consisting in a Named Patient Program (NPP). This program allows the use of Beleodaq® at the request of physicians for patients who are directly designated, even if the product doesn’t have a marketing authorization (MA) in Europe. This waiver to the regular status of drugs with MA is strictly regulated and only patients without available therapeutic options can benefit from this program through individualized requests from their physician.

Lymphoma is the most common blood cancer*. Hodgkin’s and non-Hodgkin’s lymphoma are its two main forms. Lymphoma occurs when the lymphocytes, a type of white blood cell, increase abnormally and accumulate in one or more lymphatic ganglions or in lymphatic tissue. Two types of lymphocytes may develop: B lymphocytes (B cells) and T lymphocytes (T cells). Peripheral T-Cell Lymphoma (PTCL) is a sub-type of non-Hodgkin’s lymphoma which affects T cells. In the United States, PTCL accounts for around 10 to 15% of non-Hodgkin’s lymphoma and its global incidence is estimated at 12,000 cases each year. Currently no 2nd line treatment is available in Europe once the disease has progressed after a 1st line of treatment. *Lymphoma Research Foundation (
