Company stops development of eryaspase in ALL

Red blood cells

Erytech Pharma said it plans to stop development of eryaspase for acute lymphoblastic leukemia (ALL).

This means withdrawal of the European marketing authorization application for eryaspase as a treatment for relapsed and refractory ALL.

However, Erytech will continue development of eryaspase as a treatment for certain solid tumor malignancies.

Eryaspase consists of L-asparaginase encapsulated inside donor-derived red blood cells. These enzyme-loaded red blood cells function as bioreactors to eliminate circulating asparagine and “starve” cancer cells, thereby inducing their death.

Erytech noted that eryaspase has produced favorable efficacy and safety results in ALL.

However, based on recent feedback from regulatory agencies in Europe and the US, the company believes significant additional investment would be required to seek regulatory approval of eryaspase for the treatment of ALL. Erytech also believes there would be a limited market opportunity for eryaspase in ALL.

Therefore, the company decided to cease further clinical development efforts in ALL. The resources that will become available as a result of this decision will be allocated to the development of eryaspase in solid tumors.

In 2017, Erytech announced results from a phase 2b clinical trial of eryaspase plus chemotherapy in patients with second-line metastatic pancreatic cancer. The company expects to begin enrollment in a phase 3 trial of this patient population in the third quarter of 2018.

In addition, Erytech is preparing for a pair of phase 2 proof-of-concept trials of eryaspase. One is in first-line pancreatic cancer, and the other is in metastatic triple-negative breast cancer. The company is also evaluating development options in additional solid tumor indications with high unmet medical need.

To ensure an adequate supply of eryaspase, Erytech is constructing a large-scale manufacturing facility in Princeton, New Jersey, and is expanding its manufacturing capacity in Lyon, France. The company expects both facilities to be operational for clinical production at the expanded capacity in the first quarter of 2019.
