Adalimumab formulations
The present invention relates to novel liquid pharmaceutical compositions of adalimumab, which include adalimumab or a biosimilar thereof, an histidine buffering agent such as histidine (or histidine buffer system such as histidine/imidiazolium-histidine), and a sugar stabiliser such as trehalose. Such a combination of components furnishes formulations having a stability (e.g. on storage and when exposed to stress) which is comparable to or an improvement upon those known in the art, and with fewer ingredients. Such advances will help adalimumab treatments to become more widely available at lower cost, and prolong the viability of pre-loaded delivery devices (e.g. pre-filled syringes) to reduce unnecessary waste of the drug.
1. An aqueous pharmaceutical composition comprising:
(a) 45-55 mg/mL adalimumab;
(b) a histidine buffering agent or histidine buffer system;
(c) 100-250 mM sorbitol; and
(d) 0.05 mg/mL to 1.5 mg/mL Polysorbate 20 and Polysorbate 80;
wherein the composition:
has a pH between 5.0 and 6.7;
is free of amino acids other than histidine; and
is free of phosphate buffering agents; and
comprises at most one sugar stabilizer.
2. The aqueous pharmaceutical composition of claim 1 , wherein the adalimumab is present at a concentration of 50 mg/mL.
3. The aqueous pharmaceutical composition of claim 1 , wherein the histidine buffering agent or histidine buffer system is present at a concentration of at least 5 mM.
4. The aqueous pharmaceutical composition of claim 1 , wherein the sorbitol is present at a concentration of 100-210 mM.
5. The aqueous pharmaceutical composition of claim 1 , wherein the polysorbate 20 is present at a concentration of 0.5 to 1.1 mg/mL.
6. The aqueous pharmaceutical composition of claim 1 , wherein the composition further comprises a citrate buffer.
7. The aqueous pharmaceutical composition of claim 1 , wherein the composition further comprises sodium chloride as a tonicifier present at a concentration of 25 to 75 mM.
8. The aqueous pharmaceutical composition of claim 1 , wherein the sorbitol is present at a concentration of 100 to 150 mM.
9. The aqueous pharmaceutical composition of claim 1 , wherein the composition comprises a non-buffering tonicifier which is the sorbitol.
10. The aqueous pharmaceutical composition of claim 1 , wherein the composition comprises only a single non-buffering tonicifier, which is the sorbitol.
11. The aqueous pharmaceutical composition of claim 1 , wherein the pH of the composition is between 5.0 and 6.0.
12. The aqueous pharmaceutical composition of claim 1 , wherein the composition consists of:
(a) 45-55 mg/mL adalimumab;
(b) a histidine buffer system alone or in combination with a further buffer system;
(c) 100-200 mM sorbitol;
(d) 0.05-1.5 mg/mL polysorbate 20; and
(e) water;
wherein the composition has a pH between 5.0 and 6.5.
13. The aqueous pharmaceutical composition of claim 1 , wherein the composition consists of:
(a) 50 mg/mL adalimumab;
(b) a histidine buffer system alone or in combination with a further buffer system;
(c) 100-150 mM sorbitol;
(d) 0.5-1.1 mg/mL polysorbate 20; and
(e) water;
wherein the composition has a pH between 5.0 and 6.0.
14. The aqueous pharmaceutical composition of claim 1 , wherein the composition consists of:
(a) 50 mg/mL adalimumab;
(b) a buffer system consisting of a histidine buffer system and a citrate buffer system;
(c) 100-150 mM sorbitol;
(d) 0.5-1.5 mg/mL polysorbate 20; and
(e) water;
wherein the composition has a pH between 5.0 and 6.0.
