Description
PEMETREXED FORMULATIONS
BACKGROUND OF THE INVENTION
Compounds exhibiting anti-folate activity have a well known role as chemotherapeutic agents. One such compound is pemetrexed, which has the chemical name N-[4-[2-(2-amino-4,7- dihydro-4-oxo-l H-pyrrolo [2,3-d]pyrimidin-5-yl)ethyl]benzoyl]-L-glutamic acid and the structure of formula (1):
Pemetrexed is used in the treatment of pleural mesothelioma and non-small cell lung cancer. ALIMTA, Eli Lilly's pemetrexed product is presently supplied in 100 mg and 500 mg vials of lyophilized pemetrexed disodium for injection. According to the prescribing information, in order to prepare ALIMTA for infusion the vials are reconstituted in sufficient 0.9% Sodium Chloride Injection (preservative free) to give a solution containing 25 mg/mL of ALIMTA. This concentrated solution is then further diluted into a solution of 0.9% Sodium Chloride Injection (preservative free). The prescribing information cautions that reconstitution and further dilution is only recommended with 0.9% Sodium Chloride Injection (preservative free), and that "ALIMTA is physically incompatible with diluents containing calcium, including Lactated Ringer's Injection, USP and Ringer's Injection, LISP and therefore these should not be used."
Calcium containing diluents, such as Lactated Ringer's Injection and Ringer's Injection, are common solutions used in medical settings for the reconstitution and/or dilution of drug products prior to intravenous administration. There is a need for pemetrexed dosage forms that are chemically stable after reconstitution and/or dilution with diluents containing calcium. In addition to being useful with a wider range of available diluents, the use of such a dosage form would minimize both the loss of dosage forms due to improper reconstitution or dilution and the
risk that a patient would be administered pemetrexed reconstituted or diluted in an incompatible diluent.
In solution, pemetrexed undergoes hydrolysis and degrades rapidly. Due to this rapid degradation, pemetrexed formulations must either be lyophilized for long term stability or comprise stabilizers. However, reconstitution of a lyophilized formulation requires multiple steps, each of which increases the risk of user error. In addition, reconstitution of a lyophilized formulation is clinically inconvenient and can take up to 30 minutes.
While stable, ready to use formulations of pemetrexed are known, they require stabilizers, such as anti-oxidants or amino acids as described in US6,686,365; CN 101081305; and WO 2012015810, or high levels of non-aqueous solvents, as described in WO2013144814. It would be advantageous to minimize patient exposure to these additional ingredients.
As such, there is a need for a stable, non-lyophilized pemetrexed composition with a minimal amount of additional ingredients. To this end, we have developed a stable pemetrexed formulation.

EXAMPLES
Example 1: Effect of Non-Aqueous Solvents on Pemetrexed Stability Formulations as described in Table 1 were prepared as follows:
Water for Injection, a suitable base solution (0.1 - 1 N NaOH or KOH), and citric acid, if present, were combined and mixed to yield a visually uniform mixture. Pemetrexed diacid was incrementally added to the mixture under continuous agitation, and the resulting homogenous suspension was agitated until all solids were completely dissolved. The pH of the solution was adjusted to about 7.4-7.6. Propylene glycol, if present, was then added to the pemetrexed solution, and the mixture was agitated until a visually uniform mixture was obtained. The pH of the solution was adjusted to 7.4-7.6.
The stability of Formulations B, C, F, and I was tested under accelerated conditions at
60°C and 40°C/75% RH over the course of several days. Samples were taken at various time points and diluted with HPLC diluents (60:40 (v/v, Water: ACN)) prior to testing. Impurities were measured by HPLC.
The results are shown in Tables 2A-2D and Figures 1 A-1D.

The long term stability, real-time, and projected, of formulations B, I, and K (See Table 4, prepared as described above) were also measured. Results are shown in Table 3
Table 3: Long Term Stability of Pemetrexed Formulations B, L and K
Table 4: Pemetrexed Formulation K
Example 2: Stability of Pemetrexed Formulation K after dilution.
The stability of pemetrexed for up to 48 hours after dilution of Formulation K was evaluated. . Normal saline, water for injection and 5% dextrose in water, Ringer's Injection, and Lactated Ringer's Injection were purchased directly and used as is. The pH of each diluent was tested and recorded in Table 6.
Table 6: pH of diluents
Formulation K (25 mg mL) was diluted to 0.15, 1.5, and 15 mg/mL in the diluents listed above. The mixtures were stored at 2-8° C and tested at 12, 24, and 48 hours for appearance, assay, impurities, and pH. A sample was taken immediately after dilution for the time zero sample. The 0.15 mg/mL samples were analyzed as is without further dilution, while the 1.5 mg/mL and 5 mg/mL samples were diluted with HPLC diluents (60:40 (v/v. Water: ACN)) prior to testing. Results are in Tables 6 & 7 (each Table represents separate studies).
