Pipeline Updates

ROLONTIS (eflapegrastim), a novel long-acting G-CSF

• FDA is actively reviewing the BLA for ROLONTIS for the treatment of chemotherapy-induced neutropenia. The PDUFA target action date for the ROLONTIS BLA is October 24, 2020.
• Company-sponsored study evaluating the administration of ROLONTIS on the same day as chemotherapy, dosed its first patient. The trial will evaluate the duration of severe neutropenia when administered at three different time points on the same day following standard chemotherapy in patients with early stage breast cancer.

Poziotinib, an irreversible tyrosine kinase inhibitor targeting EGFR and HER2 mutations

• Spectrum presented additional results for Cohort 1 from its Phase 2 clinical trial, ZENITH20, evaluating poziotinib in previously treated non-small cell lung cancer (NSCLC) patients with EGFR exon 20 insertion mutations at a plenary session of the virtual American Association for Cancer Research annual meeting on April 27, 2020. The podium presentation included additional safety and efficacy data. Although the results for Cohort 1 did not meet the primary endpoint, as previously announced, poziotinib demonstrated a 68.7% disease control rate.
• Spectrum provided an update on its ZENITH20 trial evaluating poziotinib in NSCLC patients with EGFR and HER2 exon 20 insertion mutations. The protocol has been amended to explore additional dosing regimens and the earlier use of corticosteroids in an effort to increase drug compliance.
• Cohort 2 of the ZENITH20 trial enrolling previously treated HER2 NSCLC patients is fully accrued as previously announced and is expected to have topline results released in mid-2020. Cohort 3 of the ZENITH20 trial enrolling first-line EGFR NSCLC patients is now fully enrolled and is expected to have topline results in the second half of 2020. Either cohort has the potential to support a future NDA submission.

About ZENITH20

The ZENITH20 study consists of seven cohorts of NSCLC patients. Cohorts 1 (EGFR) and 2 (HER2) have completed enrollment of previously treated NSCLC patients with exon 20 mutations.

Cohort 5 includes previously treated or treatment-naïve NSCLC patients with EGFR or HER2 exon 20 insertion mutations. Cohort 6 includes NSCLC patients with classical EGFR mutations who progressed while on treatment with first-line osimertinib and developed an additional EGFR mutation. Cohort 7 includes NSCLC patients with a variety of less common mutations in EGFR or HER2 exons 18-21 or the extracellular or transmembrane domains.
