On April 26, 2016 Zymeworks Inc., a leader in the development of bi-specific and multi-specific antibodies and antibody drug conjugates, reported that it has entered into a new licensing agreement with GSK for the research, development, and commercialization of novel bi-specific antibodies enabled using Zymeworks’ Azymetric drug discovery platform (Press release, Zymeworks, APR 26, 2016, View Source [SID1234536466]). Under the agreement, GSK will have the option to develop and commercialize multiple bi-specific drugs across different disease areas. Zymeworks will receive upfront and preclinical payments of up to USD$36 million and is eligible to receive up to USD$152 million in development and clinical milestone payments, along with commercial sales milestone payments of up to USD$720 million, and tiered royalties on potential sales.

As previously announced in December 2015, Zymeworks and GSK entered into a collaboration and license agreement to further develop Zymeworks’ Effector Function Enhancement and Control Technology (EFECT) platform and to research, develop, and commercialize novel Fc-engineered monoclonal and bi-specific antibody therapeutics that have been optimized for specific therapeutic effects. As part of this second agreement, GSK has also gained the right to combine the Azymetric platform with novel engineered Fc domains developed under the previously announced collaboration.

"We are excited to be expanding our relationship with GSK to include our Azymetric bi-specific platform. We view this new collaboration as evidence of our valuable role as a partner and the strength of our proprietary drug development platforms," said Ali Tehrani, Ph.D., President and CEO of Zymeworks. "The proceeds from this collaboration will be used to advance our pipeline of therapeutic candidates, including the Azymetric antibody ZW25 and the Azymetric antibody drug conjugate ZW33, into human clinical trials this year. They will also be utilized to support the continued expansion and strengthening of our core capabilities in antibody discovery, protein engineering, and antibody drug conjugates."

About the Azymetric Platform
Bi-specific antibodies developed using the Azymetric platform resemble conventional mono-specific antibodies while being able to simultaneously bind to two different targets resulting in additive or synergistic therapeutic responses. Azymetric antibodies spontaneously assemble into a single molecule with two different Fab domains comprising of unique heavy and light chain pairings. Azymetric antibodies are manufactured using conventional monoclonal antibody processes and can also be easily adapted to rapidly screen target and sequence combinations for bi-specific activities in the final therapeutic format thereby significantly reducing drug development timelines.

About the EFECT Platform
The EFECT platform is a library of antibody Fc modifications engineered to modulate the activity of the antibody-mediated immune response, which includes both the up and down-regulation of effector functions. This platform is compatible with traditional monoclonal as well as Azymetric bi-specific antibodies to further enable the customization of therapeutic responses for different diseases.

Breast cancer is the most frequently occurring disease among women worldwide. The early stage of breast cancer identification is the key challenge in cancer control and prevention procedures. Although gene expression profiling helps to understand the molecular mechanism of diseases or disorder in the living system, gene expression pattern alone is not sufficient to predict the exact mechanisms. Current proteomics tools hold great application for analysis of cancerous conditions. Hence, the generation of differential protein expression profiles has been optimized for breast cancer and normal tissue samples in our organization. Normal and tumor tissues were collected from 20 people from a local hospital. Proteins from the diseased and normal tissues have been investigated by 2D gel electrophoresis and MALDI-TOF-MS. The peptide mass fingerprint data were fed into various public domains like Mascot, MS-Fit, and Pept-ident against Swiss-Prot protein database and the proteins of interest were identified. Some of the differentially expressed proteins identified were human annexin, glutathione S-transferase, vimentin, enolase-1, dihydrolipoamide dehydrogenase, glutamate dehydrogenase, Cyclin A1, hormone sensitive lipase, beta catenin, and so forth. Many types of proteins were identified as fundamental steps for developing molecular markers for diagnosis of human breast cancer as well as making a new proteomic database for future research.

Ewing’s sarcoma is a devastating rare pediatric cancer of the bone. Intense chemotherapy temporarily controls disease in most patients at presentation but has limited effect in patients with progressive or recurrent disease. We previously described preliminary results of a novel immunotherapy, FANG(TM) (Vigil(TM)) vaccine, in which 12 advanced stage Ewing’s patients were safely treated and went on to achieve a predicted immune response (IFN? ELISPOT). We describe follow-up through year 3 of a prospective, non-randomized study comparing an expanded group of Vigil-treated advanced disease Ewing’s sarcoma patients (n=16) with a contemporaneous group of Ewing’s sarcoma patients (n=14) not treated with Vigil. Long-term follow up results show a survival benefit without evidence of significant toxicity (no = grade 3) to Vigil when administered once monthly by intradermal injection (1x10e(6) cells/injection to 1x10e(7) cells/injection). Specifically, we report a 1-year actual survival of 73% for Vigil treated patients compared to 23% in those not treated with Vigil. In addition, there was a 17.2 month difference in overall survival (OS; Kaplan-Meier) between the Vigil (median OS 731 days) and no Vigil patient groups (median OS 207 days). In conclusion, these results supply the rational for further testing of Vigil in advanced stage Ewing’s sarcoma.

To describe treatment patterns, outcomes and healthcare resource use in patients with metastatic and/or locally recurrent, unresectable gastric cancer (MGC) in Taiwan.
Patients who had received first-line therapy (platinum and/or fluoropyrimidine) followed by second-line therapy or best supportive care (BSC) only were eligible. Participating physicians provided de-identified information from patient charts. Data were summarized descriptively and Kaplan-Meier analysis was used to describe time to events.
Overall, 37 physicians contributed 122 patient charts. Of the 122 patients (median age, 61 years; 62% male), 43 (35%) received BSC only following first-line therapy, whereas 79 (65%) received second-line therapy. There was heterogeneity in second-line treatment, although fluoropyrimidine with or without a platinum agent was most frequently used. Median survival was 12.5 (interquartile range [IQR], 8.2-20.8) months from MGC diagnosis for patients receiving second-line therapy and 8.0 (IQR, 5.6-not reached) months for patients receiving BSC only. The most common treatment-related symptoms were nausea/vomiting (58%); the most common cancer-related symptoms were pain (61%), ascites (35%) and nausea/vomiting (33%). Inpatient and outpatient hospitalizations were numerically more common for patients receiving second-line therapy than for those receiving BSC only; the prevalence of hospice and skilled nursing facility stays were numerically more common for patients receiving BSC only.
In this Taiwanese MGC population, 65% received active second-line therapy with heterogeneity seen in the regimen used. Clinical outcomes suggest an unmet medical need in this population. This study may help inform clinical practice and future research to ultimately improve patient outcomes in Taiwan.

In December 2014, we nominated AP32788 for clinical development and are currently conducting studies necessary to support the filing of an investigational new drug (IND) application. We expect to file the IND by the end of 2015 and to commence a Phase 1/2 proof-of-concept clinical trial of AP32788 in 2016.
