clinical trial
Hello out there!
This is part of a request for additional information regarding a clinical trial.
Concernant la substance active:
L'origine des HMW de grande taille pour le lot de substance active du Procédé X présente une polydispersité plus importante que le lot du Procédé Y
I was the thinking "high molecular weight" but then there should be something that that is modifying. Am I on the wrong track?
I would appreciate your thoughts!
Thank you.

Disaggregation of high-molecular weight species during downstream processing to recover functional monomer.
Xu X1, Didio DM, Leister KJ, Ghose S.
Author information
Abstract
The use of chaotropic agents to recover functional monomeric material was investigated for the downstream purification of an Fc-fusion protein containing high levels of high-molecular weight (HMW) species. In batch studies, chaotropic agents irreversibly disaggregated a majority of the aggregated protein. An integrated processing mode, termed as on-column disaggregation, was developed in which the protein was captured on Protein A chromatography and then a chaotropic agent was used to simultaneously elute the bound protein and disaggregate the HMW species. On-column disaggregation process resulted in protein recoveries of >95% and aggregation reduction of approximately 50%. Analytical results are presented showing that the recovered monomeric material was comparable to the reference protein in biochemical, biophysical, and pharmacokinetic properties. The kinetic and molecular mechanisms governing protein aggregation and disaggregation will also be elucidated. For the Fc-fusion protein studied here, incorporation of the disaggregation strategy in both batch and on-column modes led to an increase of >10% in overall downstream yield.

Helen Genevier
: HMW species seems a great solution to me, as there are so many possibilities besides protein and DNA. I'd precede it by "large" in case the author is referring to a subset of HMW species./You too, Sue :-)

https://en.wikipedia.org/wiki/Dispersity
The dispersity index, or formerly polydispersity index (PDI), or heterogeneity index, or simply dispersity (Đ), is a measure of the distribution of molecular mass in a given polymer sample. Đ (PDI) of a polymer is calculated: , where is the weight average molecular weight and is the number average molecular weight.

Early clinical studies by Mistry (4,5) demonstrated that a high-molecular-weight glucose polymer osmotic agent, similar to icodextrin, was superior to other glucose polymer osmotic agents of lower molecular weight and higher polydispersity. Improved osmotic agents for long-dwell PD solutions have previously been ..
