Janssen Wins Darzalex Royalties Arbitration Battle Against Genmab

Summary :

Janssen Pharmaceutical, a division of Johnson & Johnson, won an arbitrary victory against royalty choices arising from the licencing and marketing of daratumumab, an anti-CD38 monoclonal antibody therapy with numerous FDA-approved applications (FDA). A three-person tribunal conducted the confidential arbitration earlier this week.

Janssen Wins Darzalex Royalties Arbitration Battle Against Genmab

In this arbitration, two topics were discussed.

  • The first is connected to a Janssen-Genmab licencing arrangement. Daratumumab is a drug that Genmab holds the rights to develop, manufacture, and market. While Janssen must pay Genmab sales royalties on the product in every nation where it is sold until all of Genmab’s associated patents expire or are invalidated, this did not apply to the Janssen-owned patent. Within the next decade, these patents will expire.’
  • The second issue that went to arbitration was how these royalties would be divided with a third firm, Halozyme Therapeutics, in exchange for Halozyme’s formulation of daratumumab that was administered subcutaneously. Also in Janssen’s advantage, the ruling will allow the business to continue to self-regulate the situation by splitting payments made to each company. Janssen deducts the difference between proper royalties paid to Halozyme and payments made to Genmab prior to and as a result of this arbitration.

About Daratumumab

Daratumumab, sold under the brand name Darzalex, is an anti-cancer monoclonal antibody medication. It binds to CD38, which is overexpressed in multiple myeloma cells

Daratumumab was originally created by Genmab, but it is now being developed jointly by Genmab and Janssen Biotech, a Johnson & Johnson company that bought the drug’s worldwide marketing rights from Genmab. Daratumumab was designated as a breakthrough therapy medication for multiple myeloma in 2013.

For multiple myeloma, diffuse large B cell lymphoma, follicular lymphoma, and mantle cell lymphoma, it was given orphan drug designation.

Mechanism of action

Daratumumab binds to CD38, causing cells to apoptose via antibody-dependent cellular cytotoxicity, complement-dependent cytotoxicity, inhibition of mitochondrial transfer or antibody-dependent cellular phagocytosis.

Daratumumab is an antibody directed against a protein called CD38, which is found on the surface of multiple myeloma cells. Once daratumumab attaches itself to the cells expressing CD38, it summons the body’s immune system to attack and destroy those cells.

  • Brand and Other Names :Darzalex
  • Classes: Antineoplastics, Monoclonal Antibody; Antineoplastics, Anti-CD38 Monoclonal Antibodies

The antibody treatment was the first to be approved for the treatment of multiple myeloma and the sole approved treatment for light-chain amyloidosis. The medication works by attaching antibodies to CD38 molecules, which triggers an immune response and apoptosis in tumour cells.

The medicine has been granted the brand name Darzalex by Janssen, with the purpose of using it in conjunction with other drugs and personalising treatment to the indication. Darzalex Faspro is a medication that is sold in combination with hyaluronidase-fihj.

To accurately discuss the outcomes of participants, the study protocol included follow-ups, the topic of Janssen’s update. These follow-ups, which were conducted at 38.6 months on average, contributed to the overall positive results.  Progression-free survival in both arms was one of the key indicators of the drug’s success, along with a lack of safety concerns. The minimal residual disease negativity rate continued to stay high in comparison to patients that were dosed with lenalidomide and dexamethasone alone, who served as the control group.
