The new toxSYN platform consists of four highly potent payloads, which offer multiple mechanisms of action and a viable path for commercialization when combined with the components of the company’s GlycoConnect and HydraSpace technologies:

Syneamicin functionalized calicheamicin (DNA damaging agent)
SYN-38 functionalized SN-38 (topoisomerase 2 inhibitor)
Synstatin E functionalized auristatin E (microtubule inhibitor)
Syntansine functionalized maytansine (microtubule inhibitor)
All the payloads have been clinically validated with well-known efficacy and safety profiles, and were selected to address the two types of biologies that exist across ADC targets which include rapidly-dividing cancer cells as well as quiescent cells, such as cancer stem cells.

"We expect this important expansion of our ADC technology to further advance our internal research and facilitate collaborations with a much broader set of companies" said Peter van de Sande, CEO of Synaffix. "By providing these four distinct payloads through our new toxSYN platform, we can now enable any company with an existing antibody to rapidly establish a highly-competitive clinical-stage ADC program for its own development pipeline."

About Synaffix Site-Specific ADC Platform Technology

The growing experience of Synaffix and its collaboration partners continues to confirm the ability of our conjugation platform technology to consistently generate ADCs that are more effective and better tolerated when compared to all three major clinical-stage ADC conjugation technologies. The proprietary conjugation technology platform of Synaffix is comprised of GlycoConnect, the site-specific and stable antibody conjugation technology that involves proprietary enzymes and metal-free click conjugation components, and HydraSpace, the highly polar ADC-enhancing spacer technology.

GlycoConnect was shown to be capable of significantly enhancing the therapeutic index of an ADC on its own. The highly polar properties of HydraSpace improve the solubility and stability of the payload and the resulting ADC product, thus enhancing further the therapeutic index of the ADC.

Both technologies have demonstrated compatibility with all ADC payload classes and all IgG isotypes and can be applied directly to an existing antibody without any DNA and or protein engineering.

On December 6, 2017 Foundation Medicine, Inc. (NASDAQ:FMI) reported that new data generated with FoundationOneHeme, its comprehensive genomic profiling (CGP) assay for hematologic malignancies and sarcomas, will be presented at the American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting (Press release, Foundation Medicine, DEC 6, 2017, View Source [SID1234522397]). Data from a broad range of blood cancers, including acute myeloid leukemia (AML), myeloproliferative neoplasms (MPN), and non-Hodgkin lymphoma (NHL), including primary central nervous system lymphoma (PCL), demonstrate the value of integrating FoundationOneHeme into clinical care. The data presented is expected to demonstrate the potential for CGP to improve disease classification, to offer personalized prognostic information and to support therapeutic treatment decision making by informing treating physicians about the use of novel treatment options, including cancer immunotherapies.

"Comprehensive genomic profiling (CGP) is proving to be an essential component for personalized cancer care, particularly as we learn more about the diverse genomic alterations in blood cancers," said Vincent Miller, M.D., chief medical officer at Foundation Medicine. "FoundationOneHeme is at the forefront of helping to identify new treatment approaches, including cancer immunotherapy, for individuals with blood cancers. Our new findings to be presented at ASH (Free ASH Whitepaper) support the ability of CGP to address high unmet medical needs across a wide range of hematologic malignancies, including rare conditions for which there are few treatment options."

Cancer immunotherapy is emerging as a therapeutic tool for patients with diverse hematologic malignancies. New results to be presented at ASH (Free ASH Whitepaper) using FoundationOneHeme show that more than one-quarter of patients with PCL had high tumor mutational burden (TMB), a genomic biomarker that has been shown across several cancer types to predict response to immuno-oncology treatment strategies, such as checkpoint inhibitors. Less than 50 percent of PCL patients achieve complete remission with current standard of care treatments, underscoring a need for new treatment options for these patients.

New results also support the role of FoundationOneHeme to guide therapy selection and predict response to treatment. In an oral study to be presented, FoundationOneHeme detected NTRK fusions in a wide variety of hematologic malignancies, and clinical response to a TRK inhibitor was subsequently observed in a patient with refractory AML and an ETV6-NTRK2 fusion. In another study to be presented, CGP offered insights that may facilitate risk-adapted clinical management decisions in patients with intermediate-and favorable-risk AML, potentially informing optimal use of autologous stem cell transplantation (auto-SCT) over conventional consolidation chemotherapy. For example, the study showed the presence of PTPN11 mutations to predict long term clinical outcomes following an auto-SCT.

Other results to be presented at ASH (Free ASH Whitepaper) demonstrate the ability of FoundationOneHeme to detect both known and novel BCL6 rearrangements in NHL, including cases that previously tested negative with standard-of-care single marker testing. BCL6 rearrangements have known diagnostic and prognostic utility in specific subtypes of NHL.

Foundation Medicine and collaborators will present a total of nine studies, including four oral presentations and five poster presentations, at the ASH (Free ASH Whitepaper) Annual Meeting from December 9-12, 2017 in Atlanta. The planned presentations are as follows:

The poster, presented by Manav Korpal, Ph.D., is titled "Development of a first-in-class oral selective ERα covalent antagonist (SERCA) for the treatment of ERαWT and ERαMUT breast cancer" and is taking place in the following session:

Session: Poster Session 1: Treatment: New Drugs and Treatment Strategies (5:00 PM – 7:00 PM)
Date/Time: Wednesday, December 6, 2017, 5:00 PM
Room: Hall 1

"We are encouraged by the initial results that H3B-6545 demonstrated over the current standard of care agents in preclinical models," said Markus Warmuth, M.D., President and CEO, H3 Biomedicines. "At H3, our research in breast cancer seeks to advance the understanding of this debilitating illness and work towards discovering novel treatments for those affected by the disease."

The poster presented at SABCS demonstrated that H3B-6545 has a unique mode of ERα antagonism and exhibits superior preclinical anti-tumor activity to fulvestrant in the MCF-7 xenograft model with once daily oral dosing, achieving maximal antitumor activity at doses >10x below the maximum tolerated dose in mice. In addition, H3B-6545 demonstrated superior preclinical anti-tumor activity to both tamoxifen and fulvestrant in patient derived xenograft models of breast cancer carrying estrogen receptor mutations. Based on these results, in September, 2017, H3B-6545 entered into a Phase 1 multi-center, open-label study to evaluate the safety, pharmacokinetics, pharmacodynamics and clinical activity of the compound in women with ER-positive, Her2-negative metastatic breast cancer. Please refer to www.clinicaltrials.gov for additional clinical trial information.

"The results from the preclinical models indicate a new mode of inhibition, covalent antagonism of ERα, is potent in in vitro and in vivo models of breast cancer," said Pete Smith, Ph.D., Chief Scientific Officer, H3 Biomedicine. "The fact that current ER-directed therapies are only partially effective in the ERα mutant setting, and that a significant proportion of resistant breast cancer metastases continue to remain dependent on ERα signaling for growth/survival, highlights the critical need to develop the next generation of ERα antagonists that can overcome aberrant ERα activity."

About H3B-6545

H3B-6545 is an orally bioavailable, potent and selective small molecule modulator of wild-type and mutant Estrogen Receptor (ERα). Scientists at H3 Biomedicine have discovered a new class of ERα antagonists called Selective Estrogen Receptor Covalent Antagonists (SERCAs) that inactivate the estrogen receptor by targeting a cysteine that is not present in other nuclear hormone receptors. SERCAs have a unique biological and activity profile compared to Selective Estrogen Receptor Modulators (SERMs) and Selective Estrogen Receptor Degraders (SERDs). Preclinical data indicates H3B-6545 inhibits the growth of cell line and patient-derived xenograft models of wild-type and mutant ERα with improved activity over standard-of-care therapies. Initial clinical development will target breast cancer patients with wild-type and mutant ERα and will assess the safety, pharmacokinetics, pharmacodynamics and preliminary efficacy of H3B-6545.

On December 6, 2017 Sirnaomics, Inc. (www.sirnaomics.com), a leading biopharmaceutical company in discovery and development of RNAi therapeutics, reported that the Office of Orphan Product Development division of the FDA has granted Orphan-drug designation to its leading therapeutic candidate, STP705, for the treatment of Cholangiocarcinoma (CCA) (Press release, Sirnaomics, DEC 6, 2017, View Source [SID1234523487]).

Sirnaomics lead product candidate, STP705, is an siRNA (small interfering RNA) therapeutic which takes advantage of a dual-targeted inhibitory property and polypeptide nanoparticle (PNP)-enhanced delivery to directly knock down both TGF-β1 and COX-2 gene expression. The product has also received both US FDA and Chinese FDA IND approval for Hypertrophic Scar Reduction and it is expected to have efficacy in many diseases across multiple therapeutic areas. The Orphan Drug application was supported by recent results of in vitro and in vivo studies using a human cholangiocarcinoma cell line and its xenograft tumor in a mouse model.

"We are very pleased to reach this significant milestone and we are very excited to develop our lead product candidate for this oncology indication," stated Dr. Patrick Lu, founder and CEO. "This is the fourth major clinical milestone we have achieved in the past twelve months including our FDA and CFDA IND approval for STP705 for the treatment of Hypertrophic scar as well as our Orphan Drug Designation approval for Primary Sclerosing Cholangitis. The antifibrotic and antitumorigenic properties of STP705 may bring an alternative therapeutic approach for treatment of devastating cancers such as cholangiocarcinoma and others."

"The Orphan designation for CCA is a very important step for Sirnaomics and the positive data allows us to develop STP705 in a devastating oncology disease with no effective therapy," stated Dr. Michael Molyneaux, Sirnaomics’ CMO. "This Orphan designation aligns with our mission to alleviate human suffering and target diseases with high unmet clinical need and we anticipate filing an IND for CCA sometime in the first half of 2018."
