PENTRA® Antibody Fragments
Delenex fragments are best-in-class, clinically proven antibody fragments which significantly expand the therapeutic application range due to their unsurpassed qualities:
1.  New administration routes (e.g. epicutaneous, intranasal)
2. Local applications (e.g. skin, CNS, GIT, lung)
3. Combat tissue-borne diseases (e.g. diseases affecting joints, skin, lung)
4. Fight acute systemic medical conditions in which rapid and short intervention is of the essence (e.g. acute pain, intoxication, cytokine storm)

Delenex provides stable, proprietary antibody fragments with low molecular weights ranging from about 25 kDa to 50 kDa. This small size, 1/6 and 1/3, respectively, of a full length immunoglobulin, as well as the PENTRA® fragments’ inherent features markedly expand the clinical application opportunities.


PENTRA® fragments are clearly differentiated from other fragments and non-antibody scaffolds:

1.  Best-in-class biophysical parameters
2.  Proven in clinical trials
3.  Easy generation and handling
4.  Favourable, robust and proven GMP-production conditions in bacterial systems
5.  Commercialisation benefits
a. Independent, versatile antibody technology
b. No royalty stacking or other fees
c. Comprehensive patent/patent application portfolio established and maintained
d. Validated through the acquisition of ESBATech by Alcon Inc. in 2009
