Endocyte Announces FDA Acceptance of Radiographic Progression Free Survival (rPFS) as an Alternative Primary Endpoint of the VISION Trial in Addition to Overall Survival (OS)

On September 10, 2018 Endocyte, Inc. (Nasdaq:ECYT), a biopharmaceutical company developing targeted therapeutics for personalized cancer treatment, reported that following a meeting with the U.S. Food and Drug Administration (FDA), it was determined that rPFS is an appropriate efficacy endpoint in the ongoing phase 3 VISION trial to support the submission of a New Drug Application (NDA) for full FDA approval of 177Lu-PSMA-617 for the treatment of metastatic castration-resistant prostate cancer (mCRPC) (Press release, Endocyte, SEP 10, 2018, View Source [SID1234529396]).

"We are very pleased with the FDA’s support of the rPFS endpoint as the basis for a submission for full approval of 177Lu-PSMA-617. This change provides an opportunity to obtain a full approval sooner than we previously anticipated and highlights the Agency’s commitment to addressing the urgent need for a new mechanism of action to treat mCRPC," said Mike Sherman, president and CEO of Endocyte. "Under the updated protocol, we now expect the analysis of rPFS for potential full approval to occur before the end of 2019. We also retained the final, fully powered OS analysis, which is expected to occur near the end of 2020. This provides two potential paths for approval and preserves a robust OS analysis to support a potential label."

Under the updated VISION trial design, the two interim assessments previously planned at 50% and 70% of OS events will be replaced with a single assessment of rPFS. This assessment is expected to occur at approximately the same time that the first interim OS assessment would have occurred under the prior trial design and shortly after the time the trial is fully enrolled. If 177Lu-PSMA-617 meets the primary endpoint in the rPFS assessment, no unexpected safety issues arise, and it demonstrates no detriment in OS relative to the control arm, Endocyte intends to submit an NDA to seek full approval in the United States. The rPFS analysis will include approximately 450 rPFS events. Regardless of the outcome of the rPFS assessment, Endocyte intends to continue to follow patients in the VISION trial in order to assess the final OS alternative primary endpoint. Other aspects of the trial, including patient treatment and assessments, trial size, overall duration, and follow up remain unchanged. The acceptance of rPFS as a primary endpoint for full approval in Europe will be determined in upcoming regulatory interactions.

VISION Phase 3 Trial Design

VISION will enroll up to 750 patients worldwide with PSMA-positive scans, randomized in a 2:1 ratio to receive either 177Lu-PSMA-617 plus best supportive/best standard of care versus best supportive/best standard of care alone. Best supportive/best standard of care is palliative in nature and, at the discretion of the clinical trial investigator, may include a novel anti-androgen drug such as enzalutamide or abiraterone. Patients treated with 177Lu-PSMA-617 will receive 7.4 gigabecquerel (GBq) intravenously every six weeks for a maximum of six cycles.

The alternative primary endpoints of the trial agreed to by the FDA are radiographic progression-free survival (rPFS) and overall survival (OS). A positive assessment on either is sufficient for full approval. In the case of the rPFS assessment, a corresponding assessment of OS will be made to ensure no detriment in OS has occurred. Secondary endpoints include response evaluation criteria in solid tumors (RECIST) response and time to first symptomatic skeletal event. An efficacy analysis of rPFS and OS will be conducted at approximately 450 and 490 events, respectively. Further information on the global phase 3 VISION trial can be found at View Source

Innovent’s Anti-CD47 Antibody IBI188 Receives IND Approval in China

On September 9, 2018 Innovent Biologics (Innovent), a world-class China-based biopharmaceutical company that develops and commercializes high quality drugs, reported that its IND application for IBI188, a fully human anti-CD47 monoclonal antibody (mAb) drug candidate, has been approved by the National Medical Products Administration (NMPA, formerly known as CFDA) for clinical trials (Press release, Innovent Biologics, SEP 9, 2018, View Source [SID1234529358]). Innovent will launch several clinical trials based on this mAb drug to assess its safety and efficacy for multiple tumor types, including non-Hodgkin’s lymphoma and ovarian cancer. This is the fourth IND approval the company has received this year, including anti-CTLA-4 mAb, anti-RANKL mAb, anti-OX40 mAb and anti-CD47 mAb.

As one of the key targets in the field of anti-tumor immunotherapy, CD47 is regarded by many experts to have the possibility of becoming the next "star" in the field of immuno-oncology following the ground-breaking success of PD1 / PD-L1 antibodies. The IND approval signals that Innovent’s discovery and development on CD47 has advanced IBI188 as a leading player for this target to enter into clinical development stage.

"Innovent, with a relentless focus on innovation and quality, has developed programs that are advancing into cutting edge drug development frontiers. We hope that through our efforts, we can advance the field of cancer treatment, provide better treatment options to increase patients’ survival rate and improve their quality of life," said Michael Yu, Founder, Chief Executive Officer and Chairman.

"Emerging data suggests that CD47 antibody in combination with other treatments, including anti-PD-1 monoclonal antibodies, could result in higher levels of anti-tumor efficacy. Innovent’s current rich pipeline will allow multiple drug combinations with IBI188 creating many opportunities to achieve breakthroughs in cancer treatment to meet more unmet patient needs in the future," said Dr. Kerry Blanchard, Chief Scientific Officer of Innovent.

CD47 is one of the most important targets in the field of immuno-oncology. The development of anti-CD47 monoclonal antibody has recently attracted much attention. Innovent will be among one of a few companies pursuing the development of an anti-CD47 antibody in the early clinical stage.

About IBI188

IBI188 is an anti-CD47 IgG4 monoclonal antibody developed by Innovent with independent intellectual property rights. Both in vitro and in vivo experiments showed that IBI188 can bind to the CD47 antigen on the surface of tumor cells, block the CD47-SIRPα signaling pathway, inhibit the "Don’t Eat Me" signal, and promote the phagocytosis of tumor cells by macrophages, thereby exerting an anti-tumor effect. It has stronger receptor blocking ability than similar drugs. Innovent will launch several clinical trials to assess its safety and efficacy for multiple tumor types, including non-Hodgkin’s lymphoma and ovarian cancer.

Xspray Pharma announces positive clinical data for its lead product candidate HyNap-Dasa

On September 9, 2018. Xspray Pharma reported positive data from a clinical bioequivalence study with the company’s lead product candidate HyNap-Dasa (Press release, Xspray, SEP 9, 2018, View Source [SID1234649534]). The study results confirmed its primary aim to show bioequivalence of an optimized formulation of HyNap-Dasa compared to Sprycel. The data will be instrumental in the design of the planned registration study for an ANDA application.
The completed clinical Phase I study examined HyNap-Dasa’s bioavailability compared to the dasatinib cancer drug, currently marketed as Sprycel for the treatment of chronic myeloid leukemia (CML). In the study, bioavailability of two different tablet formulations of HyNap-Dasa was tested in comparison with Sprycel tablets in 16 healthy subjects. The results are very positive and confirm the validity of Xspray’s patented formulation technology. The planned studies required to take HyNap-Dasa to final registration studies will now be performed as planned. The results also strengthen the potential for additional product candidates in the pipeline being developed with the same technology to reach the market.

"I am happy to see that the data so strongly confirm our technology. The outcome of this study represents an important milestone for Xspray Pharma as it means that we now can initiate the preparation of the pivotal phase of the clinical program, taking us closer to a commercial launch of HyNap-Dasa. Furthermore, the results pave the way also for additional product candidates in our pipeline. It signifies a new and important step in our development as a company" said Per Andersson, CEO of Xspray Pharma.

The clinical results in summary:

The study compared the pharmacokinetic parameters Cmax and AUC for the originator product Sprycel and two different HyNap tablet formulations of dasatinib. Sixteen healthy volunteers received single doses of each product in a cross-over design. Although this study was not powered to demonstrate formal bioequivalence, an analysis of preliminary data indicate that bioequivalence with Sprycel was achieved for one of the HyNap formulations. The results demonstrate a high likelihood that formal bioequivalence will be achieved in an adequately powered study.
