Nov 21Spectrum held a Type A meeting with the FDA to better understand the issues identified in the Response CRL. At that meeting, the company learned that the deficiencies at the fill finish site have been adequately addressed. Remediation of deficiencies at the drug substance facility are well under way and expected to be completed by the end of the year. The FDA confirmed that the reinspection of the drug substance facility would be in-person [8,9]
Aug 21Complete Response Letter (CRL) received from the FDA for the BLA for eflapegrastim. The CRL cited deficiencies related to manufacturing and indicated that a reinspection will be necessary [8]

Trial or other data

Feb 18Spectrum Pharmaceuticals announces treatment with eflapegrastim met its primary endpoint of non-inferiority in duration of severe neutropenia between eflapegrastim and pegfilgrastim in the PIII ADVANCE trial (NCT02643420) [2].
May 17Pivotal PIII RECOVER trial to assess the safety and efficacy of eflapegrastim for the treatment of chemotherapy-induced neutropenia in patients with early-stage breast cancer receiving docetaxel and cyclophosphamide starts (SPI-GCF-302; NCT02953340). 218 patients will be recruited in the US. Primary endpoint is the duration of severe neutropenia (Absolute Neutrophil Counts [ANC] <0.5×109/L) in cycle 1 of chemotherapy, based on central laboratory assessment of ANC over the 21 days cycle. Secondary endpoints include the incidence of neutropenic complications, incidence of febrile neutropenia, relative dose intensity and safety [1].
Dec 15PIII registrational ADVANCE trial for the treatment of chemotherapy-induced neutropenia in patients with newly diagnosed, early-stage breast cancer starts (NCT02643420). 406 patients will be randomised to SC eflapegrastim or pegfilgrastim in the US and Canada. The study is powered at over 90% for non-inferiority and at 80% for superiority to pegfilgrastim [1].
