Application Number:	US17/835,236
Patent Claims:	1. A liquid pharmaceutical composition, consisting of: 20 mg/mL to 30 mg/mL of pemetrexed diacid; 200 mg/mL to 300 mg/mL of propylene glycol; 12 mg/mL to 24 mg/mL of tromethamine; optionally HCl; and water, wherein the pH of the composition is from about 7.4 to 7.6, wherein the composition is suitable for multi-dose administration, and wherein the composition remains stable when stored for about 14 months at a temperature of 2° C. to 8° C. in a container having a head-space oxygen content of about 20% v/v, such that the composition comprises no more than 3% w/w of total impurities after said storage. 2. The liquid pharmaceutical composition of claim 1, consisting of: 25 mg/mL of the pemetrexed diacid; 250 mg/mL to 300 mg/mL of the propylene glycol; 17 mg/mL to 21 mg/mL of the tromethamine; optionally HCl; and water, wherein the pH of the composition is from about 7.4 to 7.6. 3. The liquid pharmaceutical composition of claim 1, consisting of: 25 mg/mL of the pemetrexed diacid; 250 mg/mL to 300 mg/mL of the propylene glycol; 18 mg/mL to 20 mg/mL of the tromethamine; optionally HCl; and water, wherein the pH of the composition is from about 7.4 to 7.6. 4. A vial containing a liquid pharmaceutical composition consisting of: 20 mg/mL to 30 mg/mL of pemetrexed diacid; 200 mg/mL to 300 mg/mL of propylene glycol; 12 mg/mL to 24 mg/mL of tromethamine; optionally HCl; and water, wherein the pH of the composition is from about 7.4 to 7.6, wherein the composition remains stable when stored for about 14 months at a temperature of 2° C. to 8° C. in a container having a head-space oxygen content of about 20% v/v, such that the composition comprises no more than 3% w/w of total impurities after said storage. 5. The vial of claim 4, wherein the vial is a multi-dose vial. 6. The vial of claim 4, wherein the vial contains: 25 mg/mL of the pemetrexed diacid; 250 mg/mL to 300 mg/mL of the propylene glycol; and 17 mg/mL to 21 mg/mL of the tromethamine. 7. The vial of claim 6, wherein the vial is a multi-dose vial. 8. The vial of claim 4, wherein the vial contains: 25 mg/mL of the pemetrexed diacid; 250 mg/mL to 300 mg/mL of the propylene glycol; and 18 mg/mL to 20 mg/mL of the tromethamine. 9. The vial of claim 8, wherein the vial is a multi-dose vial.
