ApcinteX is focused on developing SerpinPC for the treatment of Hemophilia A (HA) and Hemophilia B (HB). Hemophilia is a rare bleeding disorder that is caused by a deficiency of thrombin generation upon vascular damage. SerpinPC, a biologic of the serpin family of proteins, is designed to allow more thrombin to be generated by inhibiting Activated Protein C (APC).

ApcinteX’s approach is to rebalance coagulation in hemophilia by decreasing a single anticoagulant force. SerpinPC has the potential to treat all types of hemophilia regardless of severity or inhibitor status, and may also prevent bleeding associated with other bleeding disorders. ApcinteX seeks to develop SerpinPC as a one-size-fits-all approach for the treatment of HA and HB.

Capella Bioscience was created with the mission to advance monoclonal antibody (mAb) therapeutics in autoimmune diseases with high unmet need. Our lead programs are CBS001 and CBS004, currently undergoing IND-enabling studies for the treatment of rare inflammatory disorders.

Capella Bioscience is developing CBS001, a neutralizing therapeutic mAb to the inflammatory membrane form of LIGHT (known as TNFSF14) for the treatment of idiopathic pulmonary fibrosis (IPF). In addition, the company is developing CBS004, a therapeutic mAb to target BDCA-2 for the treatment of lupus erythematosus, both systemic and cutaneous (SLE and CLE, respectively), and systemic sclerosis (SSc).


Janpix is focused on discovering and developing a novel class of small molecule protein degrader therapeutics which are designed to covalently and selectively bind to target proteins and thereby degrade them. We believe that these monovalent small molecule protein degraders may have significant advantages over existing approaches, allowing therapies to target certain proteins that have been historically considered “undruggable.”

Janpix is developing dual degraders of Signal Transducer and Activator of Transcription proteins 3 and 5, known as STAT3 and STAT5, for the treatment of hematological malignancies, including leukemias and lymphomas.

LockBody is pioneering a platform technology to develop LockBody CD47 (LB1) and LockBody CD3 (LB2) for optimal targeting of solid tumors by the innate immune system. LockBody aims to develop novel therapeutics based on its platform technology that is designed to selectively drive CD47 or CD3 activity while avoiding systemic toxicity.

As compared to the mechanism of bispecific antibodies, LockBody technology is monospecific until activated, and thereby is intended to address the classical limitations of bispecific antibodies by locking the cell-killing mechanism of action, such as CD47 or CD3, beneath a well-tolerated tumor targeting arm such as HER2 or PD-L1.

LockBody seeks to leverage its technology to generate lead compounds with novel mechanisms of action to address solid tumors, which previously have not been addressed by CD47 or CD3-targeting therapies and are resistant to current standard of care.


Morphogen-IX was founded in 2015 to identify and develop bone morphogenetic proteins, or BMPs, as a novel therapy for the treatment of pulmonary arterial hypertension, or PAH. PAH, a severe form of pulmonary hypertension, is a progressive life-limiting disease caused by the narrowing of small pulmonary arteries in the periphery of the lung.

Morphogen-IX’s lead product candidate, MGX292, is a disease-modifying, protein-engineered variant of human bone morphogenetic protein 9 (BMP9) for the treatment of PAH.

Orexia Therapeutics was created with a mission to develop innovative medicines that activate the orexin neurotransmitter system in the brain, a clinically elucidated target, with a focus on the treatment of narcolepsy and other neurological disorders. Orexia’s co-founders include Sosei Heptares, a leading biopharmaceutical drug discovery and development company with proprietary structure-based drug design (SBDD) technology for G protein-coupled receptor (GPCR) targets including the orexin receptors.

Orexia seeks to expand treatment options for patients with narcolepsy type 1 (NT1), which is a chronic rare disease with high unmet medical need. The company is advancing an oral orexin agonist program for NT1, which we believe may offer improved tolerability and activity as compared to current therapies for NT1, as well as a novel orexin agonist approach for intranasal administration. We believe the introduction of orexin agonists as novel therapeutics will represent a disruptive approach in the treatment of NT1 because orexin agonists, unlike any current marketed treatments, have the potential to directly address the underlying pathology of the disorder, which is the profound loss of orexinergic neurons. The therapeutic potential for orexin agonists extends beyond NT1 into other rare primary hypersomnia disorders such as narcolepsy type 2 and idiopathic hypersomnia, and into a broad range of other indications characterized by excessive daytime sleepiness.


Palladio Biosciences was created with the goal of developing transformative medicines for orphan diseases of the kidney. Palladio is actively investigating its lead product candidate, lixivaptan, an oral, non-peptide, new chemical agent that works by selectively suppressing the activity of the hormone vasopressin at the V2 receptor, as well as evaluating lixivaptan's potential to deliver a differentiated safety profile for patients with autosomal dominant polycystic kidney disease (ADPKD).

PearlRiver Bio aims to improve treatments for cancer patients by developing novel, precision medicines that target the tumors of patients with unmet medical need. PearlRiver Bio is developing small molecule kinase inhibitors, designed to inhibit difficult-to-treat epidermal growth factor receptor (EGFR) mutations that are resistant to currently available therapies. Its proprietary scientific platform allows PearlRiver Bio to design potential best-in-class therapeutics that selectively target difficult-to-treat oncogenic kinases that are the mechanistic drivers of disease with the potential to bring safe and effective medicines to patients.

PearlRiver Bio’s lead program targeting exon 20 mutations aims for highly potent and selective, oral, exon 20 insertion mutation inhibitors that have a robust therapeutic window over wild type EGFR and optimal pharmacokinetics. PearlRiver Bio’s second program targeting C797S mutations aims to develop a potentially first-in-class EGFR inhibitor with an innovative mechanism of action to overcome osimertinib resistance. In addition to the exon 20 frontrunner and C797S development programs, PearlRiver Bio has built a proprietary platform technology intended to support the design of next generation EGFR inhibitors.


Pega-One was created to identify and develop oncology medicines in areas of high unmet need. The first asset, imgatuzumab, is an anti-EGFR tumor-targeting monoclonal antibody (mAb) with enhanced antibody-dependent cellular cytotoxicity (ADCC) and antibody-dependent cellular phagocytosis (ADCP) properties licensed from Roche.

Pega-One is initially developing imgatuzumab as an investigational agent for the treatment of cutaneous squamous cell carcinoma (CSCC). Pega-One is also exploring imgatuzamab’s potential in combination with either immunotherapy or small molecules across multiple oncology indications.

Z Factor is a clinical-stage biotechnology company founded in 2015 to identify and develop therapeutic agents to treat alpha-1-antitrypsin deficiency, or AATD, a common genetic disorder where a single mistake in the DNA encoding the protein alpha-1-antrypsin causes both liver and lung disease.

Z Factor’s lead product candidate, ZF874, is a novel compound that acts as a molecular patch for the faulty protein, allowing it to fold correctly, thereby simultaneously relieving the liver burden of polymer accumulation and providing fully-functional Z-A1AT in the circulation to protect the lungs.

The first human volunteer was dosed with ZF874 in August 2020 in a Phase 1 clinical trial designed to determined how safe and effective ZF874 is at raising levels of Z-A1AT in humans in a short period of time.
