POZ-lipid conjugates and lipid nanoparticles (LNPs) including POZ-lipid conjugates used to facilitate delivery of an encapsulated payload. LNPs including POZ-lipid conjugates and a nucleic acid payload such as, but not limited to, mRNA or modified mRNA are disclosed. Such LNPs have no immunogenicity or reduced immunogenicity as compared to a corresponding LNP containing a PEG-lipid.

Polyoxazoline-lipid conjugates and lipid nanoparticles and pharmaceutical compositions including same

The present disclosure provides polymer conjugates comprising a polymer and an agent the agent linked to the polymer via a linking group containing a cleavable moiety.

Subcutaneous delivery of polymer conjugates of therapeutic agents

Described are conjugates comprising a water-soluble polymer linked to a compound comprising a catechol moiety via a cleavable linkage, wherein the cleavable linkage is formed between the water-soluble polymer and a first phenolic hydroxyl group of the catechol moiety and a second phenolic hydroxyl group of the catechol moiety is linked to a blocking group wherein the rate of hydrolytic release of the compound comprising the catechol moiety is controlled, at least in part, through structure or design of the blocking group on the second phenolic hydroxyl group of the catechol moiety. Therefore, the rate of hydrolytic release of the compound comprising the catechol moiety can be tuned through structural design of the group on the second phenolic hydroxyl group of the catechol moiety. Compounds used in the synthesis of the described conjugates and methods of using the described conjugate and other compounds in the treatment of dopamine-responsive disorders are also described.

Cleavable conjugates of catechol compounds and water-soluble polymers and methods of treatment using the same

The present disclosure provides polymer conjugates comprising a polymer and an agent, the agent linked to the polymer via a linking group containing a cleavable moiety.

Subcutaneous delivery of polymer conjugates of therapeutics agents

The present disclosure provides polymer conjugates comprising a polymer and an agent, the agent linked to the polymer via a linking group containing a hydrolyzable moiety.

Subcutaneous delivery of poly(oxazoline) polymer conjugates

In the present disclosure, polymer conjugates, including polymer-antibody-drug conjugates (polymer ADCs) are described, as well as the use of such conjugates to treat human disease. The polymer conjugates can contain a large number of polymer-bound agents, thus effectively increasing the drug antibody ration (DAR) of the antibody significantly beyond the currently available technology. This may be of particular importance when antibodies to low density antigens are used as target antibodies. The described polymer-ADCs have improved pharmacokinetics and solubility relative to traditional ADCs. The linker between agent and the polymer can be tailored to provide release of toxin at the desired site and under the desired conditions within the tumor. An additional feature of the polymer-ADCs of the current disclosure is that a purification moiety can be attached to the polymer backbone to provide ease of purification of the polymer-ADCs.
