Igenica Biotherapeutics (Igenica) is a privately held biotechnology company located in Burlingame, California, founded in 2009. Igenica is harnessing the natural tumor microenvironment to deliver a pipeline of high-impact antibody-based cancer therapeutics.
The acquisition of Igenica enables immediate access to proprietary technology and preclinical drug candidates. To date, Igenica has raised six rounds of private financing totaling $83 million in venture capital funded by a premier team of life science investors including The Column Group, OrbiMed, 5AM Ventures and Third Rock Ventures.
Igenica Biotherapeutics has a patent portfolio that consists of twelve (12) families which include twenty-four (24) patent and provisional applications and seven (7) international PCT applications with the intent to protect the company’s antibody platform (so as to make sure this platform is different from the ADC Technology), ADC technology, preclinical and clinical assets.
Igenica has developed:
· A novel technology (sTAg) for Identifying overexpressed proteins on tumor cell surfaces
· A novel method (iTAb) to generate tumor antigen specific monoclonal antibodies
· A novel antibody dependent conjugation platform (SNAP) including a proprietary linker
· Several well characterized drug candidates that show promise in preclinical studies
· One clinical drug candidate, IGN523, which halted development post a phase I dose escalation trial due to lack of efficacy in AML. The company believes that IGN523 may show promise as a combination therapy or for an indication other than AML
· A large, pending patent estate which has ongoing prosecution, but no issued patents as of this date
Igenica has no recurring revenues, product or collaboration related. Its value lies in the preclinical and clinical assets produced by its underlying and proprietary technology.

Historical Company Information
Igenica’s foundational vision was to build a biopharmaceutical company with a complete suite of technologies supporting the discovery of antibody-based therapeutics. Our rigorous approach to target discovery and antibody development considers patient profile, tissue expression, the tumor micro-environment and antibody function as primary factors.
Our target discovery platform, sTAg (surface Tagged Antigen), systematically profiles proteins found on the cell surface of primary tumors to identify antibody-accessible antigens as candidate targets. Tumor-specific surface proteins are identified and quantified by applying advanced mass spectrometry analysis.
To identify functional antibodies that are specific to target candidates, we developed a platform, iTAb (in vivo anti-Tumor Antibody), that generates diverse antibodies and screens Ab candidates in vivo, to select antibodies with the most potent anti-tumor activity. This platform has been applied to develop naked functional antibodies, including next-generation immune-oncology therapies for cancer.
Our proprietary site-specific ADC platform technology, SNAP, addresses the major limitations of current and competitive approaches by providing a simple, elegant, chemically-driven method for linking a functional Ab and small molecule cytotoxin. Our SNAP technology results in a highly flexible bi-functional linker that, by design, yields homogeneous ADCs armed with the optimal toxin payload. SNAP is also a highly flexible system that is amenable to any antibody, linker or toxin, and can tune the drug-to-antibody ratio (DAR) to specifically 2, 3, or 4, making it an ideal technology for internally and externally generated programs.
Igenica Company Profile
Igenica is focused on the discovery and development of immune-modulating antibodies and antibody-drug conjugates (ADCs) for the treatment of cancer. We are the only biotherapeutic company that fully powers the ADC development spectrum from a clinically relevant approach to target and functional antibody discovery to ADC creation, accelerating development and the delivery of effective therapies to patients.
Founded in 2009, Igenica is led by a proven team of leaders that have demonstrated success in antibody drug discovery, clinical development and commercialization. Based in Burlingame, Calif., we were well-funded by a premier team of life science investors including The Column Group, OrbiMed, 5AM Ventures and Third Rock Ventures.
Igenica Biotherapeutics has a patent portfolio that consists of twelve (12) families which include twenty-four (24) patent and provisional applications and seven (7) international PCT applications with the intent to protect the companies’ platform, ADC technology, preclinical and clinical assets.
Impact of Technology on the Market and Why Igenica Assets are Attractive
We are focused on the development of innovative immunotherapies, functional antibodies directed to the tumor, and antibody-drug conjugates for the treatment of cancer. All of Igenica’s product candidates were discovered using our proprietary product engine.
· iTab platform generates high-affinity antibodies with broad epitope coverage and in vivo anti-tumor efficacy in preclinical models
· SNAP platform can provide homogeneous drug-to-antibody ratios (DARs) of 2, 3, or 4, is adaptable to all payload classes and reduces manufacturing risks of ADCs
· Igenica’s antibodies are of high affinity and cover various elements of immunotherapy
· Combination therapy with Igenica antibodies have the potential to significantly impact anticancer immunotherapy
· Igenica antibodies have been tested in preclinical efficacy models and/or cynomolgus monkeys for safety
· Intellectual Property
· Numerous preclinical studies demonstrating anti-tumor efficacy in various tumor models, safety and PK/PD assessments in non-human primates
· Procedures and methods for target identification, antibody generation and antibody drug conjugation chemistry
Igenica developed IGN523 (anti-CD98) for the treatment of multiple hematologic and solid tumors. Expression of CD98 has been shown to be upregulated in a variety of hematologic malignancies, including AML, and in several types of solid tumors, particularly squamous cell carcinomas. Its elevated expression is correlated with poor prognosis and patient outcome. Previous studies have demonstrated that CD98 functions both in integrin signaling and amino acid transport processes, which support the proliferation, anchorage-independence, invasion, and metastasis of tumor cells (Cancer Cell 2016; 30(5): 792-805; Int. J. Cancer 2015; 137(3): 710-720).
· IGN523 is a high affinity antibody that works through multiple mechanisms of action potentially reducing the risk of developing treatment resistance
· IGN523 has been in a Phase 1 clinical trial in patients with relapsed or refractory acute myeloid leukemia (AML). The trial has been designed to assess the safety, pharmacokinetics, and clinical activity of IGN523
· Preclinical studies indicate that in addition to AML non-small lung cancer patients express high levels of CD98 and could benefit from IGN523 treatment
· Immunohistochemical staining reagents are available to be developed as a patient stratification tool
· IGN523 can be readily produced as master cell bank with contract manufacturer is available
IGN381 forms the basis for an innovative approach to immunotherapy by targeting an immune checkpoint target called VISTA or c10orf54 that plays a complimentary role in the tumor micro-environment to other known immune checkpoints. Igenica developed an active antibody program and has humanized a lead candidate. We believe this program is well positioned to complement existing immunotherapy approaches.
· IGN381 is a high affinity mAb with data supporting immune checkpoint inhibition differentiation relative to lead competitor mAb
· Safety of IGN381 has been assessed alone and together with anti-PD1 antibody (pembrolizumab) in a PK/PD 6 weeks repeat-dose study in non-human primates
· Strong evidence of VISTA immune regulatory function in a non-redundant, MDSC-mediated immune regulatory axis
· Extensive expression profiling reveals that VISTA expression pattern is consistent with extensive role on MDSCs and unique among immune checkpoint regulators
· Increased expression in immune infiltrates within tumors may result in decreased overall survival of NSCLC patients
· Igenica has identified a putative heterophilic binding partner for VISTA
· Patent applications on these antibodies and other novel aspects of this program have been filed
Discovered using Igenica’s sTAg protoemics technology, SAIL (c16orf54) has not been studied or described in humans previously. Given the expression profile of this target, IGN786 has the potential to be an exquisitely specific targeted therapy for multiple cancer indications with high unmet medical need, including follicular lymphoma, diffuse large B-cell lymphoma (DLBCL), acute myeloid leukemia (AML), chronic lymphocytic leukemia (CLL), multiple myeloma, and pancreatic cancer. Igenica developed IGN786 as an antibody-drug conjugate using Igenica’s proprietary ADC technology. Igenica has filed patent applications with claims protecting multiple unique aspects of this novel therapeutic agent (Blood Cancer J 2015; 5: e316).
· SAIL is a highly novel ADC target derived from a proteomics-based target discovery approach
· IGN786 leverages Igenica’s SNAP ADC technology to optimally target SAIL-expressing tumors
· Based on the expression profile of SAIL, IGN786 is being developed to address high unmet medical need in multiple hematologic and solid tumor indications
· IGN786 induces tumor regression in multiple AML xenograft models
· IGN786 displays a favorable toxicology profile in non-human primates (NOAEL of 20 mg/kg)
· Strong evidence CD39 immune regulatory function through purinergic signaling within the CD39/CD73/adenosine pathway
· CD39 expression profile reveals higher levels of expression in tumors, Tregs and myeloid cells within the TME relative to normal tissues
· 9-8B mAb is a high affinity anti-CD39 mAb with data supporting functional blocking of CD39 ATPase activity (Am J Trans Res 2015; 7(6): 1181-1188)
· 9-8B inhibits tumor growth through cell killing in vivo
· 9-8B mAb has been humanized in silico
· Patent applications have been filed on Igenica’s antibodies and methods of treatment
