Pioneering Next Generation Nanodrugs for Targeted Treatments of Cancers
Our team has built a robust pipeline of potential first-in-class and/or best-in-class nanodrug for targeted therapeutics. We have an ongoing drug discovery research focus in single protein encapsulation(SPE) – a new generation nanodrug with high potency and low toxicity and low production cost. Our most advanced pipeline programs include SPEDOX, a single protein encapsulated Doxorubicin. The preclinical study has completed and also it is scientifically-validated via publication, potentially much more indications would be applied due to its higher potency, higher dosing and lower toxicity.
​
Since inception, Sunstate Biosciences’ research focus has been to exploit the concept of single protein encapsulation, an approach for indirectly targeting oncogenic pathways, it does not involve nanoparticle assembly and modifications to either small-molecule drugs or HSA, may open up a new avenue for developing new drug delivery systems to improve anticancer therapeutics.
​
We have established calibration with Cedars-Sinai, City of Hope, USC & Caltech to develop the clinical pipelines, SPEDOC, SPEDOXDOC, TRACAM. We are aggressively pursuing federal government grants, SBIR (NCI & NSF), DOD breast cancer breakthrough awards & NIH R01 academic/industry collaboration research grants.
​
Sunstate Biosciences is located in Monrovia, California.

Single Protein Encapsulation
A novel drug delivery platform
​
SPE Technology Advantages:
​
(I), No nanoparticles (NP). After encapsulating small-molecule drugs, the proteins do not change either their sizes or their monomeric states, resulting in non-existence of the nanoparticles. Therefore, there is a very low probability of activating immune responses in humans, which is in stark contrast to many synthetic polymer- and NP-based systems.
​
(II), No chemical modifications to either drug or protein molecules. The physical interactions between drug and protein molecules warrant the integrity of drug and protein molecules, which eliminates the cleavable linkers and completely retains the full functions of both drug and protein molecules.
(III), Robustness in the manufacturing processes. Because of no nanoparticles and no chemical modifications, the productions of SPE-DRUGs in large quantity under cGMP have been extremely simplified, requiring no separations and no purifications. Therefore, the quality of the final drug products is consistently excellent.
