Definitions
- the present invention relates to the Pharmaceutical area, in particular with pharmaceutical formulations containing recombinant proteins.
- This invention relates to stable liquid formulations of Etanercept (TNFR: Fc), a recombinant fusion protein composed of the human tumor necrosis factor type 2 receptor (TNFR) bound to the crystallizable fraction (Fe) of a human immunoglobulin G subclass 1 (IgGl).
- TNFR Etanercept
- Fc a recombinant fusion protein composed of the human tumor necrosis factor type 2 receptor (TNFR) bound to the crystallizable fraction (Fe) of a human immunoglobulin G subclass 1 (IgGl).
- formulations described in this application contain physicochemical advantages in relation to the formulations disclosed in the state of the art, more specifically in the reference formulations containing etanercept.
- the intrinsic physical and chemical properties of a therapeutic protein are susceptible to alterations during its biosynthesis, extraction, purification, transport and shelf life (Staub et al., 2011), or during any stage of its life cycle if it is exposed to conditions of deliberate or unintended stress, such as: changes in temperature, freezing and thawing processes, agitation, pH change, among others (Chang and Hershenson, 2002). Because of this, a practice for increasing the tolerance of a protein that is used as an active pharmaceutical ingredient (IFA) in a medicament consists in adding excipients to the pharmaceutical solution. Specifically, these excipients will have the function of maintaining the solubility, stability and biological activity of the protein.
- surfactant agents whose function is to prevent the formation of particles and protein adsorption on the surface of their container;
- Toning agents whose function is to grant isotonicity to the formulation in a way that is appropriate for its administration in humans.
- excipients mentioned above must be compatible with the physical and chemical properties of the protein, so that it can preserve its biological activity according to its therapeutic indication. Additionally, said excipients should not be toxic (Frokjaer and Otzen, 2005). The above constitutes the vehicle-protein system or liquid formulation.
- liquid formulations has obvious advantages over lyophilized formulations since the liquid formulation does not require rehydration (reconstitution of the lyophilisate with its diluent) and is ready to be used (Bye et al., 2014), so that it increases dosing accuracy and improves clinical use in patients (Harris et al., 2004).
- Said therapeutic preparations are suitable for parenteral administration, either subcutaneously, intravenously, intramuscularly or intraperitoneally, provided that their physical and chemical stability, as well as their biological activity can be demonstrated. This includes the inhibition of mechanisms of aggregation and degradation, reduction of denaturation-free energy, chemical modification and, particularly in therapeutic preparations that contain a high concentration of protein, such as Etanercept, alterations in the neutralization of its therapeutic target, the necrosis factor tumor tumor (TNFa).
- TNFa necrosis factor tumor tumor tumor
- Etanercept is a fusion protein (TNFR: Fc) composed of the human tumor necrosis factor type 2 receptor (TNFR) bound to the crystallizable fraction (Fe) of a human immunoglobulin G subclass 1 (IgG1); generated by recombinant DNA technology that has an approximate molecular mass of 150 kDa.
- TNFR tumor necrosis factor type 2 receptor
- Fe crystallizable fraction

- Table 2 shows the results of an experiment that evaluates the effect of thermal stress at 0, 7 and 14 days on the percentage of Etanercept aggregates. Because the concentration of Etanercept is high, there is a possibility of protein aggregation. This phenomenon can generate loss of activity and immunogenic reactions. As an overall trend, an increase in the percentage of aggregates was observed as days of stress increased, with the consequent percentage decrease in the main form of Etanercept. Specifically, candidate liquid formulations based on the Tris system presented a percentage of aggregates of up to 20% at the end of 14 days of stress. On the other hand, formulations based on histidine and succinate systems showed a percentage of aggregates of less than 7% that is similar to that of the Enbrel® formulation based on the phosphate system ( Figure 1). The results of this experiment indicated that a pH value of 6.3 is appropriate to minimize the aggregation of Etanercept.
- Table 2 shows the results of an experiment that evaluates the effect of thermal stress at 0 and 14 days on the Tm of Etanercept.
- the Tm of a protein is a measure of its structural stability in solution, providing information on the changes in the conformation of the protein induced by heat. At higher Tm a higher temperature will be required to destabilize the native structure of the protein and vice versa.
- formulations based on the Tris system were not considered due to the unsatisfactory result obtained by SEC (see table 2 and figure 1).
- the candidate liquid formulations based on histidine and succinate systems, with and without sucrose or trehalose added with polysorbate had a higher Tm than those formulations with and without sucrose, trehalose or arginine added with poloxamer, and the formulation of Enbrel® after 14 days of stress (figure 2).
- the results of this experiment indicated that a higher temperature is required to destabilize the native structure of Etanercept in the formulations containing polysorbate used as a surfactant, regardless of the buffer solution used (histidine or succinate system).
- Table 2 and Figure 3 show the results of an experiment that evaluates the effect of thermal stress at 14 days on the heterogeneity of charge of Etanercept.
- the loading variants are the effect of modifications such as deamidation, oxidation, isomerization, glycosylation, among others.
- the electrophoretic profiles showed no difference between the candidate liquid formulations based on Tris, histidine and succinate system with respect to the liquid formulation of Enbrel®. In conclusion, the physicochemical identity of Etanercept in all the evaluated formulas could be conserved (figure 3).
- the candidate liquid formulations with satisfactory results from the exploratory study were subjected to an optimization study of operating intervals for use in a manufacturing process.
- Said formulations were those based on histidine or succinate system in combination with polysorbate, mannitol and in the absence of sucrose or trehalose. Because an acceptance criterion is to make use of a smaller number of excipients and according to the results of the exploratory study, for this study formulations added with sucrose or trehalose were not considered.
- Formulations Hl-H13 formulations 1 to 13 based on histidine system.

- the bioassay is based on the ability of Etanercept to prevent the interaction of TNF ⁇ with TNF receptors present on the surface of a human monocyte cell line (U937). These techniques allowed to evaluate the percentage of purity, the Tm and biological potency, respectively.
- the biological potency of Etanercept is in a range of 80 to 125% with respect to the liquid formulation of Enbrel®.
- Table 4 shows the results of an experiment that evaluates the effect of thermal stress at 3, 7, 14 and 21 days on the percentage of Etanercept aggregates in the selected liquid formulas.
- an increase in the percentage of aggregates was observed as days of stress increased, with the consequent percentage decrease in the main form of Etanercept.
- the kinetics of aggregation (% aggregates / time (days)) of Etanercept in the selected liquid formulas and the liquid formulation of Enbrel® were calculated.
- the selected formulas have a delayed or similar aggregation kinetics with respect to the of the liquid formula of Enbrel®.
- the formulations based on histidine and succinate systems showed a similar Tm between them at 21 days and, in both cases, the maximum values were higher than the Tm of the liquid formulation of Enbrel®.
- Table 5 shows the results of an experiment that evaluates the effect of mechanical stress at 7 and 21 days on the percentage of Etanercept aggregates in the formulas selected liquids.
- a maintenance in the percentage of aggregates was observed as days of stress increased with comparable values between the candidate formulas and the liquid formulation of Enbrel®.
- Table 6 shows the results of an experiment that evaluates the effect of stress by freeze-thaw cycles on the percentage of Etanercept aggregates in the selected liquid formulas.
- the stress caused by freeze-thaw cycles had less impact on the generation of aggregates.
- an increase was observed in the percentage of aggregates as stress days increased, with the consequent percentage decrease in the main form of Etanercept.
- the values were comparable between the candidate formulas and the liquid formulation of Enbrel®.
- Figure 4 shows the results of an experiment that evaluates the biological potency of Etanercept in the selected liquid formulas.
- the potency of Etanercept determined by bioassay of inhibition of the apoptotic activity of TNFa when it interacts with the TNFR receptors present on the surface of mammalian cells allows to know the ability of Etanercept to exert its main mechanism of action in the recognition of its therapeutic target.
- the formulations based on histidine and succinate system showed a relative potency of Etanercept in the range of 80-125% with respect to the liquid formulation of Enbrel®. In conclusion, it was confirmed that Etanercept retains its biological activity and identity in the candidate formulas. Table 6. Results of the optimization study of excipient operating intervals for liquid formulation of Etanercept. Stress by freeze-thaw cycles.
- the experimental results showed that the liquid formulations based on the histidine and succinate system when used in combination with polysorbate in a pH range of 5.8 to 6.8, have a decreased percentage of impurities and an increased thermostability compared to the liquid formulation of Enbrel®.
- the latter can be represented in figure 2 in which it can be seen that the formulations of the histidine and succinate systems support higher denaturation temperatures than the liquid formulation of Enbrel®, giving evident advantages to the histidine and succinate formulations. In comparison you can see that the systems that contain poloxamer support lower denaturing temperatures.
- Said formulations manage to maintain the physicochemical identity and biological potency of Etanercept while making use of a smaller number of excipients than the formulations described in the state of the art and in a combination never before used.
