On December 6, 2018 Spectrum Pharmaceuticals, Inc. (NasdaqGS: SPPI), a biotechnology company with fully integrated commercial and drug development operations with a primary focus in hematology and oncology, reported that data from the Phase 3 RECOVER clinical study was presented during the 2018 San Antonio Breast Cancer Symposium (SABCS) (Press release, Spectrum Pharmaceuticals, DEC 6, 2018, View Source [SID1234531926]). These data confirm the efficacy and safety of ROLONTIS (eflapegrastim) in reducing the Duration of Severe Neutropenia (DSN) in breast cancer patients treated with chemotherapy. ROLONTIS is a novel, long-acting granulocyte colony-stimulating factor (G-CSF) being studied as a treatment for neutropenia in patients undergoing treatment with myelosuppressive cytotoxic chemotherapy.

"Despite available treatments, neutropenia remains a critical issue for patients undergoing chemotherapy that puts them at risk for developing life threatening infections," said Lee Schwartzberg, MD, FACP, lead investigator, professor of medicine and division chief, hematology/oncology, University of Tennessee Health Science Center, and executive director, UT/West Cancer Center. "The robust data from both Phase 3 studies demonstrate that ROLONTIS has the potential to be a valuable option in the management of neutropenia for patients undergoing treatment with chemotherapeutic agents."

The data released yesterday in a poster presentation from the ROLONTIS Phase 3 RECOVER study (n=237) showed that in Cycle 1, the mean DSN±SD was 0.31±0.688 days for ROLONTIS and 0.39±0.949 days for pegfilgrastim, demonstrating non-inferiority (p<0.0001). The non-inferiority of ROLONTIS for DSN was maintained across all four treatment cycles (all (p<0.0001)). Incidence of severe neutropenia was 20 percent versus 24 percent in the eflapegrastim and pegfilgrastim arms respectively, with a relative risk reduction of 14 percent in favor of eflapegrastim. There were no statistically significant differences on secondary endpoints such as time to absolute neutrophil count (ANC) recovery, depth of ANC nadir, and incidence of febrile neutropenia between treatment arms across all cycles. None of the ≥Grade 3 study drug related adverse events (AE) occurred in >2% of the patients and included hematologic and bone pain related AEs in both arms.

The RECOVER trial is the second ROLONTIS Phase 3 study to meet the primary efficacy endpoint of non-inferiority in mean DSN. Results from ADVANCE, the first ROLONTIS Phase 3 study, were announced at the 2018 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting and presented at the Multinational Association in Supportive Care in Cancer Annual Meeting (MASCC) earlier this year.

"The RECOVER study is the second Phase 3 study to confirm non-inferiority data and comparable safety profile between ROLONTIS and the current standard of care," said Joe Turgeon, chief executive officer of Spectrum Pharmaceuticals. "Data from both studies, which enrolled 643 patients combined, will be used to support the BLA filing which is expected to be submitted by the end of the year. If approved, we look forward to having a unique opportunity to launch and compete in this large market with the first novel G-CSF in more than 15 years."

About RECOVER

The RECOVER study is a Phase 3, randomized, open-label, active-controlled, multicenter study that enrolled 237 breast cancer patients who received docetaxel and cyclophosphamide chemotherapy every 21 days. Patients were randomized in a 1:1 ratio to receive either ROLONTIS (n=118) or pegfilgrastim (n=119). The primary study endpoint was the DSN in Cycle 1 of chemotherapy (absolute neutrophil count [ANC] <0.5×109/L), based on central laboratory assessment of ANC over a 21 day cycle. There were a total of four cycles evaluated in this study. Secondary endpoints included, the DSN in Cycles 2, 3, and 4, time to ANC recovery, depth of ANC nadir and incidence of febrile neutropenia at cycle one. Patients with stage I to stage IIIA breast cancer were treated on day one of each of the four cycles with adjuvant/neo-adjuvant docetaxel and cyclophosphamide. On day two of each cycle, patients received a single subcutaneous dose of either eflapegrastim 13.2 mg/0.6 mL (equivalent to 3.6 mg G-CSF) or pegfilgrastim (6 mg).

"Clinical progress with WP1066 has been encouraging," commented Walter Klemp, Moleculin’s Chairman and CEO. "Given its potential to address rare and difficult to treat cancers, including glioblastoma, we believe WP1066 is well positioned to qualify for Orphan Drug Status."

The FDA grants orphan drug designation to drugs and biologics that are intended for the treatment of rare diseases that affect fewer than 200,000 people in the U.S. Orphan drug status is intended to facilitate drug development for rare diseases and may provide several benefits to drug developers, including tax credits for qualified clinical trials costs, exemptions from certain FDA application fees, and seven years of market exclusivity upon regulatory product approval.

On December 6, 2018 Neon Therapeutics, Inc. (Nasdaq: NTGN), a clinical-stage immuno-oncology company developing neoantigen-based therapeutics, and Apexigen, Inc., a clinical-stage biopharmaceutical company, reported that patient dosing has begun in NT-003, Neon’s Phase 1b combination trial of NEO-PV-01 in metastatic melanoma (Press release, Apexigen, DEC 6, 2018, View Source [SID1234591000]). NEO-PV-01 is a personal neoantigen vaccine custom-designed and manufactured based on the unique mutational fingerprint of each individual patient.

The Phase 1b trial is evaluating NEO-PV-01 and nivolumab in combination with other agents in first-line patients with advanced or metastatic melanoma. One arm of the multi-arm study will evaluate the vaccine and nivolumab in combination with Apexigen’s APX005M, an investigational CD40 agonist. Another will evaluate NEO-PV-01 and nivolumab in combination with ipilimumab.

"We believe that there is very strong scientific rationale for treating patients with these additional agents as they may enhance neoantigen immune responses induced by NEO-PV-01 with the potential to drive additional clinical benefit," said Richard Gaynor, M.D., President of Research and Development at Neon Therapeutics.

"CD40 agonists such as APX005M have been shown to enhance antigen presentation, resulting in improved magnitude and quality of T cell responses and we share the enthusiasm of the team at Neon to conduct this clinical trial," said Ovid Trifan, M.D., Ph.D., Chief Medical Officer of Apexigen.

James P. Allison, Ph.D., a Nobel Prize winner, developer of the first FDA-approved checkpoint inhibitor (ipilimumab) and one of Neon’s founders, commented, "Both preclinical and clinical work have demonstrated that CTLA-4 antagonism enhances the priming of de novo immune responses and increases T cell infiltration into the tumor. These findings provide clear rationale for combining a checkpoint inhibitor such as ipilimumab with NEO-PV-01 to augment the immune response and potentially transform how we treat cancer."

About NT-003
NT-003 is a Phase 1b, open-label, multicenter clinical study of NEO-PV-01 with nivolumab, in combination either with APX005M or low dose ipilimumab, for the treatment of advanced or metastatic melanoma. APX005M or ipilimumab will only be dosed during the vaccination period.

These new data show a decrease in the total number of clinically detectable relapses with the combination of NPS + trastuzumab (7.5%) vs. trastuzumab alone (27.3%), p-value 0.004, which represents a 72.5% relative reduction in risk of relapse across time with a median follow up of 26.1 months in favor of the combination arm. Results from a planned analysis (log-rank) of the difference in disease free survival (DFS) outcomes between the two arms of the study in prespecified TNBC patient subgroups (patients who received neoadjuvant chemotherapy, expressed lower HER2, were 51 years or older, or had AJCC 7th Edition stage I/II TNBC), showed a clinically meaningful and statistically significant effect (p-value range: 0.004 – 0.014) in these subgroups in favor of the NPS plus trastuzumab combination arm. There was an average decrease of 84.2% in the relative risk of relapse or death at 24 months across these four subgroups of TNBC patients treated with NPS plus trastuzumab vs trastuzumab alone. The full data are summarized in the table below:

Comparison between NPS + trastuzumab vs. trastuzumab arms
Patient subgroups within the TNBC cohort Hazard Ratio (HR) HR 95% Confidence Interval P-value
(difference in favor of NPS + trastuzumab) Decrease in relative risk of relapse or death at 24 mos. (in favor of NPS + trastuzumab)
Received Neoadjuvant Chemotherapy 0.226 0.063 – 0.815 0.013 78.1%
Harbored BC with HER2 IHC 1+ expression level 0.178 0.038 – 0.837 0.014 81.3%
Aged ≥ 51 years 0.144 0.031 – 0.656 0.004 77.4%
AJCC 7 Stage I/II at diagnosis Incalculable* N/A 0.006 100%
*no DFS events occurred in AJCC 7 stage I/II TNBC patients treated with NPS plus trastuzumab.

"These new data provide insights on the pattern of clinically detectable relapses across various sites/organs, as well as add to our knowledge of the specific potential benefit distribution within the TNBC cohort. The results in four predefined TNBC subgroups inform us of the types of TNBC patients with residual disease after neoadjuvant chemotherapy who may potentially benefit when treated with NPS plus trastuzumab in the adjuvant setting. As previously announced, we are on track to meet with the U.S. Food and Drug Administration this month on the most expeditious and appropriate development path for NPS in TNBC," said Nicholas J. Sarlis, MD, PhD, Executive Vice President and Chief Medical Officer of SELLAS.

"We are very pleased with the results of these new analyses which indicate that the NPS plus trastuzumab combination – when given in the adjuvant setting after frontline therapy – could potentially improve outcomes across specific predefined subgroups of patients with early-stage TNBC, an aggressive subtype of breast cancer. The clinically meaningful and statistically significant decrease in the frequency of clinically detectable relapses – with a median follow-up of over 26 months – indicates a high degree of internal consistency," commented Elizabeth A. Mittendorf, MD, PhD, Rob and Karen Hale Distinguished Chair in Surgical Oncology, Director of Research, Breast Surgical Oncology Brigham and Women’s Hospital, Director, Breast Immuno-Oncology Program Dana-Farber/Brigham and Women’s Cancer Center, and the Principal Investigator of the Phase 2b study. "The data presented today are consistent with the previously reported beneficial effect seen in the TNBC cohort at large and are consistent with the immunobiological mechanism of action of nelipepimut-S."
