For a healthier world

What does Quercis Pharma do?

Quercis Pharma AG is leveraging its novel antithrombotic platform to deliver innovative, safe, and broadly accessible treatments to patients with potentially life-threatening conditions.

Our focus is on prevention of venous thrombosis and pulmonary embolism in high risk cancer patients with our drug candidate ISQ950AN, containing our patented Isoquercetin formulation.

Focused.

The safety of our investigational drug has been proven in various studies, with no serious side effects having been identified, in particular our drug shows no increased bleeding risk.

Safe.

A clinical Phase 2 study has shown that ISQ950AN reduced hypercoagulability in cancer patients at high risk for thrombosis with an improved benefit/risk ratio.

Effective.

Our novel pathway is based on a new mechanism of action, in order to arrest and/or reverse platelet aggregation with a profile that conveys vastly lowered bleeding risk compared to current standard of care.

Novel.

We control both the raw material production and the Active Performance Ingredient (API) manufacture for our investigational drug ISQ950AN through our subsidiary Quercegen Pharmaceuticals LLC., making Quercis the world’s biggest manufacturer and distributor of pure Quercetin that is GRAS (“Generally Recognized As Safe” by FDA).

Leading.

The humanitarian aspect of the Company is to look at global disease dangers in less privileged populations and to work with Governments and NGOs to improve healthcare in countries where they find it difficult to pay for development or production of new drugs to combat critical health threats (such as Ebola and Zika Viruses).

Drug Development

Product

Isoquercetin (ISQ950AN) patented formulation

Isoquercetin prevents platelet activation and initiation of the thrombotic cascade.

Over 20’000 publications referencing Isoquercetin and Quercetin in multiple indications

Safety profile of our main investigational drug is well established; does not cause bleeding – a significant advantage over Heparins and Direct Oral Anticoagulants

Lead indication: VTE prevention in cancer

Venous thromboembolism (VTE), which includes deep vein thrombosis (DVT) and pulmonary embolism (PE), is an important cause of morbidity and mortality among patients with cancer.

Besides increased risk of VTE, advanced cancer patients have a significantly increased bleeding risk.

Major bleeds are a side effect of today’s anti-coagulants (ACs).

As a result, Venous thromboembolism (VTE) prevention remains limited for advanced cancer patients, despite these patients being at a high risk of VTE.

Currently, anticoagulant use is not recommended prophylactically to cancer patients due to significantly increased bleeding risk.

Quercis’ drug is expected to prevent VTE effectively without increased risk of bleeding.

Image Description
Other high-priority indication: COVID-19

Evidence of Quercis’ drug candidate ISQ950AN being effective against a variety of virus infections (COVID-19, Influenza, HCV, hRSV, Rhinovirus, Ebola, HIV, etc).

Most patients with severe COVID-19 experience high levels of the D-dimer biomarker that underline higher risks of various forms of thrombosis particularly in the lungs. ISQ950AN’s capacity to inhibit thrombosis and decrease D-dimers in other context may prevent the life-threatening thrombotic events seen in these patients.

Various governments have requested collaboration and several Phase III trials are being prepared

Other advanced indications (Phase II trials)

Treatment of Chronic Obstructive Pulmonary Disease (COPD)

Treatment of Sickle Cell Disease (SCD)

Treatment of Amyotrophic Lateral Sclerosis (ALS) – clearly orphan disease

Treatment of thrombi

Reduction of tumor metastasis

Prevention and treatment of viral diseases
