FAQ

Frequently Asked Questions

Can you source products starting from a single box?

Yes. Depending on the product and supply situation, we can also support sourcing from a single box.

Can you source medicines distributed in Japan for clinical trials or research overseas?

Yes. Export feasibility varies depending on regulations in each country, manufacturer policies, and product characteristics, so we investigate and arrange each request individually.

Can you investigate lot information and manage multiple lots?

Yes. We support the investigation and management of lot information. The ability to specify a particular lot depends on the product and market availability.

Can you arrange documents such as CoAs and SDS/MSDS?

Where available, we can investigate and arrange CoAs, SDS/MSDS and related documents. Availability depends on the product and supplier.

Can we consult you about import/export and logistics as well?

Yes. In addition to sourcing, we can provide integrated support covering import/export-related information, necessary procedures, logistics management, and delivery to clinical trial or research sites.

How can we source another company's medicine for use as a comparator in a clinical trial?

S&A DOJIN provides integrated support based on your request, including investigating supply routes, contacting and coordinating with manufacturers as necessary, sourcing in Japan and overseas, and managing lots, related documents, and logistics. Please start by telling us which medicine you would like to purchase.

Can you source comparator drugs from overseas when they are difficult to obtain domestically?

Yes. We investigate availability in overseas markets and propose a sourcing approach after confirming import feasibility, applicable regulations, manufacturer policies, product characteristics, and other relevant factors.

Can you also contact and coordinate with manufacturers?
