About Us

This is Pamoja
Pamoja means "together". This is the vision of Hans and Ashok: Creating mono- and combination therapies together with world class universities and clinical researchers to benefit people together; regardless of their colour, class or social standing. In short, repurposing drugs to target deadly and neglected diseases in the most cost-effective way.

Product Portfolio

Actively Repur­posing
Our current product portfolio consists of:
  • 25, 50 and 100 mg artesunate tablets and matching placebos with IMPD and approved for use in clinical trials in France, Gabon and Malaysia
  • 60 mg per vial artesunate powder for solution for intramuscular or intravenous use
  • 120 mg/ml, 5 ml per vial pyronaridine parenteral solution for intramuscular or intravenous use
Combinations with other pharmaceutical actives can be developed and prepared on request.

  • Recent advances of the use of artesunate in non-malarial clinical studies:
    • Cancer treatment, e.g. a study published in EBioMedicine reported that artesunate effectively inhibits the growth of hepatocellular carcinoma cells through the induction of oxidative stress and apoptosis.
    • Anti-inflammatory properties, e.g. research published in the Inflammation journal demonstrated that artesunate could alleviate symptoms of rheumatoid arthiritis by modulating inflammatory cytokine production.
    • Viral infections, e.g. a study in Antiviral Research highlighted that artesunate exhibits potentional antiviral activitiy against the cytomegalovirus (CMV) and Hepatitis B virus (HBV), e.g. a study in Antiviral Research highlighted that certain potent activitiy against CMV, porviding a potential therapeutic option for CMV infections.
    • Antibacterial Activity, e.g. research in the The Journal of Antibiotics reported that artesunate could inhibit the growth of methicillin-resistant Staphylococcus aureus (MRSA).
    • Treatment of Autoimmune diseaes, e.g. studies published in the Lupus journal indicated that artesunate might reduce disease activity in lupus patients by moderating immune responses.

  • We have a patent pending for a parenteral pyronaridine dosage that administers the drug non-orally (e.g. intravenously, subcutaneously or intramuscularly), and which can offer several benefits:
    • Quicker therapeutic effects due to rapid onset of action
    • Enhanced bioavailability avoiding first-pass metabolism
    • Improved patience compliance and an alternative for patients unable to take oral medications
    • More precise dosing for controlled drug delivery
    • Reduced risk of resistance development by maintaining consistent drug levels
    • Synergistic effects due to potential for combination therapy

    • A parenteral pyronaridine dosage form can provide rapid, effective and reliable treatment for severe malaria, especially where oral administration is not feasible or effective.
    • Our Team

      Together for a
      better tomorrow.

      The team has long-standing experience with artesunate, having been actively involved in the development and production of artemisinin combination therapies and bringing them to the private market in Africa and South East-Asia for over 20 years.
