Description
Freeze-dried formulations of FGF-18
Field of Invention
The invention relates to the field of pharmaceutical formulations. More particularly it is
directed to freeze-dried formulations of Fibroblast Growth Factor 18 (FGF-18) protein and to
methods of producing such formulations. The freeze-dried formulations according to the
invention are stable upon storage at room temperature for an appropriate period of time.
Background of the invention
Fibroblast Growth factor 18 (FGF-18) is a member of the Fibroblast Growth Factor (FGF)
family of proteins, closely related to FGF-8 and FGF-17. Members of the FGF family are
characterized by heparin binding domains. Such a putative heparin-binding domain has been
identified for FGF-18. It is postulated that receptor-mediated signalling is initiated upon
binding of FGF ligand complexed with cell-surface heparin sulfate proteoglycans.
It has been shown that FGF-18 is a proliferative agent for chondrocytes and osteoblasts
(Ellsworth et al., 2002, Osteoarthritis and Cartilage, 10: 308-320; Shimoaka et al., 2002, J.
Bio. Chem. 277(9):7493-7500). FGF-18 has been proposed for the treatment of cartilage
disorder such as osteoarthritis and cartilage injury either alone (WO2008/023063) or in
combination with hyaluronic acid (WO2004/032849).
Pharmaceutical compositions comprising an FGF polypeptide are known from the art.
WO00/21548 discloses pharmaceutical compositions comprising a recombinant FGF in
combination with a pharmaceutically acceptable carrier or diluent. Examples of suitable
carriers or diluents for injectable solutions include water or isotonic saline solutions.
WO2008/121563 is related to pharmaceutical formulations comprising an FGF-21 compound
prepared in a unit dosage injectable form together with a pharmaceutically acceptable
carrier. Suitable carrier might be, among others, a sugar, a buffer and/or a surfactant.
WO92/01442 discloses a lyophilized composition comprising a FGF, a pharmaceutically
acceptable bulking agent and either i) an alkali metal salt of cellulose or ii) a combination of
polyoxyethylene sorbitan fatty acid ester with cysteine. The components of i) and ii) allow the
FGF composition to be stabilized.
WO01/39788 describes pharmaceutical compositions comprising an FGF-18 compound
together with a cytotoxin, in a mixture with a pharmaceutically acceptable carrier, e.g.
phosphate-buffered saline.
WO2008/023063 discloses formulations comprising an FGF-18 compound together with at
least one pharmaceutically acceptable carrier, excipients, or the like. As an example, it
discloses a formulation for injection comprising FGF-18 in vehicles such as saline, dextrose
solution, serum albumin and Ringer's solution.
When preparing a pharmaceutical composition comprising a bioactive protein, said
composition must be formulated in such a way that the activity of the protein is maintained for
an appropriate period of time. A loss in activity / stability of the protein may result from
chemical or physical instabilities of the protein notably due to denaturation, aggregation or
oxidation. The resulting products may thus be pharmaceutically unacceptable. Although the
use of excipient(s) is known to increase the stability of a given protein, the stabilizing effects
of these excipients is highly dependent of the nature of the excipients and of the bioactive
protein itself.
There remains a need for further formulations containing FGF-18 as an active ingredient,
wherein said formulations are stable for an appropriate period of time and suitable for use in
injection, preferably for intraarticular injection. Said formulations could be useful for
administration in the treatment of a cartilage disorder in a patient, such as osteoarthritis or
cartilage injury. It is an object of the present invention to go someway towards meeting this
need and/or to provide the public with a useful choice.
Summary of the invention

Definitions
- The term “comprising” as used in this specification and claims means “consisting at least in
part of”. When interpreting statements in this specification, and claims which include the
term “comprising”, it is to be understood that other features that are additional to the features
prefaced by this term in each statement or claim may also be present. Related terms such
as “comprise” and “comprised” are to be interpreted in similar manner.
- The term “FGF-18 protein” or “FGF-18”, as used herein, is intended to be a protein
maintaining at least one biological activity of the human FGF-18 protein. FGF-18 may be
native, in its mature form, or a truncated form thereof. Biological activities of the human FGF-
18 protein include notably the increase in osteoblastic activity (see WO98/16644) or in
cartilage formation (see WO2008/023063).
Native, or wild-type, human FGF-18 is a protein expressed by chondrocytes of articular
cartilage. Human FGF-18 was first designated zFGF-5 and is fully described in WO98/16644.
SEQ ID NO:1 corresponds to the amino acid sequence of the native human FGF-18, with a
signal peptide consisting of amino acid residues 1(Met) to 27(Ala). The mature form of
human FGF-18 corresponds to the amino acid sequence from residue 28(Glu) to residue
207(Ala) of SEQ ID NO: 1 (180 amino acids). FGF-18 has specificity for FGFR4 and the “IIIc”
splice variants of FGFR3 and FGFR2 (Ellsworth et al., 2002, Osteoarthritis and Cartilage, 10:
308-320). The mature form of FGF-18 has an average mass of 21.04 kDa.
FGF-18, in the present invention, may be produced by recombinant method, such as taught
by the application WO2006/063362. Depending on the expression systems and conditions,
FGF-18 in the present invention is expressed in a recombinant host cell with a starting
Methionine (Met residue) or with a signal sequence for secretion. When expressed in
prokaryotic host, such as in E. coli, FGF-18 contains an additional Met residue in N-terminal
of its sequence. For instance, the amino acid sequence of human FGF-18, when expressed
in E.coli, starts with a Met residue in N-term (position 1) followed by residues 28 (Glu) to
residue 207 (Ala) of SEQ ID NO: 1.
- The term “truncated form” of FGF-18, as used herein, refers to a protein which comprises or
consists of residues 28(Glu) to 196(Lys) of SEQ ID NO: 1. Preferably, the truncated form of
FGF-18 protein is the polypeptide designated “trFGF-18” (170 amino acids), which starts with
a Met residue (in N-terminal) followed by amino acid residues 28 (Glu) -196 (Lys) of the wild-
type human FGF-18. The amino acid sequence of trFGF-18 is shown in SEQ ID NO:2
(amino acid residues 2 to 170 of SEQ ID NO:2 correspond to amino acid residues 28 to 196
of SEQ ID NO:1). trFGF-18 is a recombinant truncated form of human FGF-18, produced in
E.coli (see WO2006/063362). trFGF-18 has been shown to display similar activities as the
mature human FGF-18, e.g. it increases chondrocyte proliferation and cartilage deposition
leading to repair and reconstruction for a variety of cartilaginous tissues (see
WO2008/023063). trFGF-18, has an average mass of 19.83 kDa.
- The term "stability", as used herein, refers to the physical, chemical, and conformational
stability of FGF-18 in the formulations according to the present invention (and including
maintenance of biological potency). Instability of a protein formulation may be caused by
chemical degradation or aggregation of the protein molecules to form higher order polymers,
deglycosylation, modification of glycosylation, oxidation or any other structural modification
that reduces at least one biological activity of an FGF-18 protein of the present invention.
- The term "stable" solution or formulation, as used herein, is one solution or formulation
wherein the degree of degradation, modification, aggregation, loss of biological activity and
the like, of proteins therein is acceptably controlled, and does not increase unacceptably with
time. Preferably, the formulation retains at least more than 80% of the FGF-18 activity over a
period of at least 12 months at room temperature. The stabilized formulation of the present
invention comprising FGF-18, has preferably a shelf-life of at least about 12 months, 18
months, more preferably at least 20 months, still more preferably about 24 months, when
stored at room temperature. Methods for monitoring the stability of the FGF-18 formulation of
the present invention are available in the art, and include the methods described in the
examples disclosed herein.
- The term "buffer", as used herein, refers to solutions of compounds that are known to be
safe in formulations for pharmaceutical or veterinary use and that have the effect of
maintaining or controlling the pH of the formulation in the pH range desired for the
formulation. Acceptable buffers for controlling pH at a moderately acidic pH to a moderately
basic pH include, but are not limited to, phosphate, acetate, citrate, arginine, TRIS, and
histidine buffers. "TRIS" refers to 2-aminohydroxymethyl-1,3,-propanediol, and to any
pharmacologically acceptable salt thereof. According to the present invention, preferable
buffers are phosphate buffers.
- The term “surfactant”, as used herein, refers to a soluble compound that can be used
notably to increase the water solubility of hydrophobic, oily substances or otherwise increase
the miscibility of two substances with different hydrophobicities. For this reason, these
polymers are commonly used in industrial applications, cosmetics, and pharmaceuticals.
They are also used as model systems for drug delivery applications, notably in order to
modify the absorption of the drug or its delivery to the target tissues. Well known surfactants
include polysorbates (polyoxyethylene derivatives; Tween) as well as poloxamers (i.e.
copolymers based on ethylene oxide and propylene oxide, also known as Pluronics®).
According to the invention, the preferred surfactant is a poloxamer surfactant and even more
preferably is poloxamer 188 (Pluronic® F68).
- The term "stabilizing agent", “stabilizer” or “isotonicity agent”, as used herein, is a
compound that is physiologically tolerated and imparts a suitable stability/tonicity to a
formulation. It prevents notably the net flow of water across cell membranes that are in
contact with the formulation. During freeze-drying (lyophilisation) process, the stabilizer is
also effective as a cryoprotectant. Compounds such as glycerin, are commonly used for such
purposes. Other suitable stability agents include, but are not limited to, amino acids or
proteins (e.g. glycine or albumin), salts (e.g. sodium chloride), and sugars (e.g. dextrose,
mannitol, sucrose and lactose). According to the present invention, the preferred stabilizing
agent is a sugar, even more preferably sucrose.
- The term "vial" or “container”, as used herein, refers broadly to a reservoir suitable for
retaining the FGF-18 formulation in lyophilized form. Similarly, it will retain the solvent for
reconstitution. Examples of a vial that can be used in the present invention include syringes,
ampoules, cartridges, or other such reservoir suitable for delivery of the FGF-18 formulation
to the patient via injection, preferably via intraarticular injection. Alternatively, the vial
retaining the FGF-18 formulation and the one retaining the solvent for reconstitution can be
presented as the 2 compartments of a dual-chamber system (syringe or cartridge for
example). Vials suitable for packaging products for intrarticular administration are well known
and recognized in the art.
-The term "solvent ", as used herein, refers to a liquid solvent either aqueous or non-
aqueous. The selection of the solvent depends notably on the solubility of the drug
compound on said solvent and on the mode of administration. Aqueous solvent may consist
solely of water, or may consist of water plus one or more miscible solvents, and may contain
dissolved solutes such as sugars, buffers, salts or other excipients. The more commonly
used non-aqueous solvents are the short-chain organic alcohols, such as, methanol, ethanol,
propanol, short-chain ketones, such as acetone, and poly alcohols, such as glycerol.
According to the present invention, the preferred solvent is an aqueous solvent such as
water or a saline solvent .
-The term “cartilage disorder”, as used herein, encompasses disorders resulting from
damages due to traumatic injury or chondropathy. Examples of cartilage disorders that may
be treated by the administration of the FGF-18 formulation described herein include but are
not restricted to, arthritis, such as osteoarthritis or rheumatoid arthritis, and cartilage injury.
- The term “Osteoarthritis” is used to intend the most common form of arthritis. It may be
caused by the breakdown of cartilage. Bits of cartilage may break off and cause pain and
swelling in the joint between bones. Over time the cartilage may wear away entirely, and the
bones will rub together. Osteoarthritis can affect any joint but usually concerns hands and
weight-bearing joints such as hips, knees, feet, and spine. In a preferred example, the
osteoarthritis may be knee osteoarthritis or hip osteoarthritis. The skilled person is fully
aware of osteoarthritis classifications that are used in the art, in particular the OARSI
assessment system (see for instance Custers et al., 2007). Osteoarthritis is one of the
preferred cartilage disorders that can be treated by administering the FGF-18 formulations
according to the present invention.
- The term “cartilage injury” as used herein is a cartilage disorder or cartilage damage
resulting notably from a trauma. Cartilage injuries can occur as a result of traumatic
mechanical destruction, notably further to an accident or surgery. Also considered within this
definition is sport-related injury or sport- related wear of tissues of the joint.
Detailed description of the invention
The present invention provides a stable freeze-dried formulation comprising FGF-18, a
buffer, a poloxamer surfactant and a sugar as stabilizing agent, wherein the buffer is a
phosphate buffer and keeps the pH comprised between 6 and 8.
Also described is a stable freeze-dried formulation comprising or consisting of an FGF-18
protein, a buffer, a poloxamer surfactant and a sugar as stabilizing agent. In a preferred
embodiment, the buffer is a phosphate buffer, the poloxamer surfactant is poloxamer 188,
and the stabilizing agent is sucrose. Preferably, the FGF-18 protein is selected from the
group consisting of: 1) a polypeptide comprising or consisting of the mature form of human
FGF-18, corresponding to the sequence comprising or consisting of residue 28(Glu) to
residue 207(Ala) of SEQ ID NO: 1, 2) a polypeptide comprising or consisting of a truncated
form of human FGF-18 comprising or consisting of residue 28 (Glu) to residue 196 (Lys) of
SEQ ID NO:1, and 3) a polypeptide comprising or consisting of SEQ ID NO:2. More
preferably, FGF-18 is trFGF-18.
The concentration of FGF-18 in the formulation described herein is preferably at or about 20
to 300 mcg/ vial, preferably at or about 20, 30, 40, 50, 60, 70, 80, 90, 100, 150, 200, 250 or
300 mcg/vial, even more preferably at or about 20, 30, 60, 100, 200 or 300 mcg/vial. FGF-18
can be added in excess of 5%, in order to prevent protein losses that could occur during
formulation. For instance, for an FGF-18 concentration of 30 mcg/vial, the compound can be
added in an amount of 31.5 mcg/vial.

In a second aspect, the invention provides a method for producing the stable freeze-dried
formulation according to the invention, comprising the steps of:
a. forming a mixture of FGF-18 together with the buffer, the surfactant and the
stabilizing agent, and
b. subjecting the mixture to lyophilization.
Also described is a method for manufacturing any of the above described stable freeze-dried
formulations of FGF-18, wherein the method comprises the steps of:
1) forming a mixture of FGF-18 together with a buffer, a poloxamer surfactant and a
sugar as a stabilizing agent, and
2) subjecting the mixture to lyophilisation.
Steps 1 and 2 are carried out using conventional procedures. As an example, in order to
prepare a suitable stable formulation, a given amount of FGF-18, such as trFGF-18, is mixed
with phosphate buffer which keeps the pH at or about 7.2, poloxamer 188 and sucrose. Each
of these compounds (i.e. FGF-18, the buffer, the surfactant and the stabilizing agent) can be
used according to the concentrations, pH, and/or ratios above described. The resulting
mixture is lyophilised and then dispensed into vials. Variations of this process will be
recognized by one of ordinary skill in the art.
In a third aspect, the invention provides an article of manufacture comprising a first container
comprising the stable freeze-dried formulation according to the invention and a second
container comprising a solvent for reconstitution.
Also described is an article of manufacture, for pharmaceutical or veterinary use, comprising:
1) a first container comprising any of the above described stable freeze-dried
formulation, said formulation comprising or consisting of FGF-18, a buffer, a poloxamer
surfactant, a sugar as a stabilizing agent, and
2) a second container comprising a solvent for reconstitution.
As an example, the first container comprises a stable freeze-dried formulation comprising or
consisting of a given amount of FGF-18, such as trFGF-18, phosphate buffer which keeps
the pH at or about 7.2, poloxamer 188 and sucrose, and the second container comprises
saline solution (0.9% w/v sodium chloride for injection). Each of these compounds (i.e. FGF-
18, the buffer, the surfactant and the stabilizing agent) can be used according to the
concentrations, pH, and/or ratios above described. Preferably, the container retaining the
FGF-18 formulation and the one retaining the solvent for reconstitution correspond to the two
compartments of a dual-chamber system (syringe or cartridge for example)
Also described, a packaging material providing instructions to reconstitute the freeze-dried
formulation of FGF-18 (first container) in the solvent (second container).
The freeze-dried formulations described herein may be kept for at least about 12 months to
about 24 months. Under preferred storage conditions, before the first use, the formulations
are kept away from bright light (preferably in the dark), at room temperature (at or about
25°C).
The stable freeze-dried formulation described herein needs to be reconstituted, preferably
under sterile condition, with a solvent, such as water or a saline solution (e.g. 0.9% w/v
sodium chloride for injection) prior to use, i.e. prior to injection. After reconstitution, the
volume to be injected is preferably from 0.5 mL to 5 mL, more preferably 0.5, 1 or 2 mL. The
FGF-18 formulation should be administered preferably within one hour of reconstitution.
The present invention provides stable freeze-dried formulations of FGF-18, in particular for
single use, suitable for pharmaceutical or veterinary use.
The stable freeze-dried formulation comprising FGF-18, described herein, can be used, after
reconstitution, for administration for improving cartilage repair or for the treatment of cartilage
disorders, such as osteoarthritis or cartilage injuries.
These stable freeze-dried formulations, after reconstitution, are suitable for use in injection
and alternative delivery systems. In a particularly preferred embodiment, the formulations of
the invention are for intraarticular injection. They can be administered, after reconstitution, by
direct injection into the synovial fluid of the joint or directly into the defect. In a preferred
embodiment described herein, the intraarticular administration is done in a joint selected from
joint of the hip, knee, elbow, wrist, ankle, spine, feet, finger, toe, hand, shoulder, ribs,
shoulder blades, thighs, shins, heels and along the bony points of the spine. In yet another
preferred embodiment the intraarticular administration is done in the joint of the hip or the
knee.
The FGF-18 formulations described herein have improved stability, and can be easily stored
at room temperature (at or about 25°C) or at 2-8 °C (see following examples), preferably at
room temperature. Indeed, the inventors have found that freeze-dried formulations
comprising FGF-18 (e.g. trFGF-18), 10 mM phosphate buffer at pH 7.2, 30 mg/vial of
sucrose and 0.2 mg/vial of poloxamer 188 are stable over time, notably when stored at room
temperature. Said formulations minimise the loss of active principle, i.e. FGF-18. It has also
been found that said formulations are more resistant to oxidation and to formation of protein
aggregates.
The following examples are provided to further illustrate the preparation of the formulations
and compositions of the invention. The scope of the invention shall not be construed as
merely consisting of the following examples.

Methods
Different assays on formulations
Standard methods were used for:
- SE-HPLC,
- RP-HPLC,
- Residual moisture,
- pH,
- Osmolality (Time 0, only),
- SDS-PAGE/SS, and
- Peptide mapping/UPLC (oxidized forms).
Protein content
The quantification of the protein, i.e. trFGF-18, in the different formulations was performed by
Biacore. Samples (25µL) containing trFGF-18 were tested (appropriately diluted in presence
of 10 mg/mL of BSA) by flowing, at 5µL/min at 25°C, over sensor surface, previously coated
with the monoclonal antibody anti-FGF-18 clone F5A2, followed by 5µL of 10mM Glycine pH
2.0 as regeneration buffer. Reference standard (IRS FGF-18 No. 051230), ranging from 125
up to 2,000 ng/mL, was run in each analytical session. Results were collected as Resonance
Unit (RU) and FGF-18 level of each sample was extrapolated from the standard curve fitted
using quadratic algorithm with Log transformed data.
Bioassay
The biological activity of FGF-18 is measured as proliferation activity by an in-vitro bioassay
using BaF3 cell line stably transfected with the FGF receptor 3c (FGFR3c). BaF3 cells
expressing FGFR3c proliferate under the FGF-18 stimuli.
BaF3/FGFR3c cells are cultured in RPMI 1640 based selective medium in the presence of r-
hIL-3 as growth factor. In order to specifically test the proliferative effect of FGF-18, cells
need to be IL-3 deprived. Therefore, cells are cultured at 37°C, 5% CO in the absence of r-
hIL-3 for 26 hours before the assay.
Standard and samples are 5-fold serially diluted in assay medium in the range of
concentration from 0.002 U/mL up to 177.5 U/mL. IL-3 deprived BAF3/FGFR3c cells (20,000
cells/well) are incubated at 37°C, 5% CO with FGF-18 in the presence of 1 µg/mL heparin,
and 10% Newborn Calf Serum, and then cell proliferation is assessed after 48 hours by
“ATPlite 1 step” luminescence assay, an ATP monitoring system based on Firefly luciferase.
Sample potency is measured applying the extended dose-response curve model. With this
model, the whole dose-response curve of standard and samples are fitted by sigmoidal dose-
response curve with variable slope (4PL) algorithm reporting cps (i.e. counts per second)
values versus log of FGF-18 concentrations. For each curve EC is automatically calculated
by GraphPad software. Sample potency is calculated on the basis of the ratio between the
EC of the reference preparation and that of the unknown sample (potency ratio). The
potency of FGF-18 is expressed as U/mL.

Freeze-dried formulations were manufactured as follows: sucrose and Poloxamer 188 were
dissolved in the phosphate buffer. Then, the needed amount of drug substance (trFGF-18)
was added, the pH checked and the solution taken to final volume. The solution was then
filtered through a 0.22 µm membrane (Durapore®) under nitrogen pressure, maintaining a
filtration ratio of about 20 cc/cm or of about 50 cc/cm .
The final solution was then manually filled, under sterile conditions into glass vials (0.5
mL/vial) and freeze-dried according to the following cycle:
STEP Temperature (°C) Duration
Loading +4 15 min
Freezing -25 2 hours
Freezing -15 1 hour and 40 min
Freezing -45 3 hours
Primary Drying -10 14 hours
Secondary Drying +35 22 hours
The freeze-dried formulations are ready to be reconstituted, at any time, with a solvent, such
as water for injection or a saline solution.
Example 2: Preliminary stability studies of FGF-18 formulations
Example 2.1: Accelerated stability conditions (at 2-8°C, 25°C and 40°C) were used in order
to identify freeze-dried pre-formulations to be further studied (data not shown).
Various preliminary freeze-dried formulations have been prepared, in order to identify the
best candidate formulations. In the frame of this preliminary study, various buffers have been
assessed, including phosphate and histidine buffers. Various concentrations of sucrose and
poloxamer 188 have also been tested. The pre-candidate formulations were tested for purity
(by SE-HPLC and RP-HPLC), protein content (by Biacore), biological activity (in-vitro
bioassay), residual moisture, pH and osmolality. Supportive stability data have also been
generated by SDS-PAGE/SS (purity) and by peptide mapping/UPLC (oxidized forms).
Example 2.2 (stability data for the preliminary formulations; data not shown): The stability
data collected for the preliminary freeze-dried formulations by SE-HPLC over 3-4 weeks
storage indicate that phosphate buffer at pH 7.2 is to be preferred, since much higher purity
level (i.e. higher % of monomer) were observed compared to histidine buffer at pH 6 (see
table 2). The amount of sucrose (15 mcg/vial vs 30 mcg/vial) plays also a role in stabilizing
FGF-18 versus aggregation, where globally higher monomer recoveries were observed with
mcg/vial of sucrose (storage at 25°C and 5°C). In addition, higher protein recovery was
observed after filtration step (before lyophilisation process) as the surfactant (i.e. poloxamer
188) was increased, with best results at 0.2 mg/vial (figure 1).
Based on the results from this pre-formulation phase, six freeze-dried formulations were
prepared for further investigations (formulations 1-6 from Table 1; also referred as candidate
formulations).
Example 3: Stability studies of FGF-18 freeze-dried formulations
Two weeks to 24 months stability data have been collected on the candidate freeze-dried
formulations of Table 1.
Example 3.1 (purity by SE-HPLC): The results for the statistical evaluation performed by
Stabileo on the stability data generated by SE-HPLC are summarized in Table 3: no
significant loss in purity (monomer content) was detected for any freeze-dried candidate
formulation upon storage at the different temperatures (up to 6 months at 40°C and up to 24
months at 25°C).
Example 3.2 ( purity by SDS-PAGE/SS): The results generated by SDS-PAGE confirmed
purity levels globally higher than 99% for any freeze-dried formulations upon storage at all
the tested temperatures (at least 6 months at 40°C and up to 18 months at 25°C). The
results are provided in Table 4.
Example 3.3 (purity by RP-HPLC): The results for the statistical evaluation performed by
Stabileo on the stability data generated by RP-HPLC are summarized in Table 5: no
significant loss in purity (% main peak) was detected for any freeze-dried candidate
formulation upon storage at the different temperatures (up to 6 months at 40°C and up to 18
months at 25°C). Therefore, formulating FGF-18 according to the present invention does not
result in any loss of purity compared to starting material (pure) FGF-18. It is noted that as the
starting material (before formulation) was not completely pure (impurities were not
completely resolved by RP-HPLC), the peak before formulation was not at 100%, but for
instance at 77.5% for FD-30 and 87.4% for FD-300 and the peak at T=0 was for instance at
76.8% for FD-30 and 87.7% for FD-300.
Example 3.4 (protein content assay): The results of the protein concentration measured by
Bioacore are summarized in Tables 6 and 7. No major loss was detected upon filtration
through the 0.22 µm membrane, i.e. almost complete protein recovery was observed (see
“AF” column in Table 6). Upon reconstitution of the freeze-dried product with 1 mL WFI (see
“T0”) column in Table 6), a lower recovery was obtained, which can be explained by
adsorption of the protein on the glass vial (upon reconstitution, the protein solution is then
exposed to a larger surface).
From a stability point of view, no loss in the protein content was detected by Biacore for all
strengths at all the tested temperatures, as shown in Table 7 (up to 6 months at 40°C and up
to 24 months at 25°C).
Example 3.5 (biological activity): Results of the biological activity (expressed in U/container)
for all of the freeze-dried candidates upon storage is provided in Table 8. For instance, the
biological activity observed for the higher strength (300 mcg/vial of trFGF-18) upon storage,
both at 25°C and 40°C was stable over time. More variability was observed with the lowest
strength FD-20. Since no change in the product stability was detected by any of the other
tests, this decrease observed with FD-20 has to be confirmed after 39, 52, 78 and 104 weeks
of storage at 25°C.
Example 3.6 (oxidized forms): The level of oxidized forms detected for all strengths upon
storage is summarized in Table 9: among the Met residues that could undergo oxidation, the
results indicate that Met 1 is more susceptible to oxidation, for all strengths and at any of the
assessed temperatures.
Example 3.7 (residual moisture): No significant increase in the residual moisture occurred
upon storage for all strengths; residual moisture values below or about 1% were globally
measured throughout the stability study (see Table 10) (up to 6 months at 40°C and up to 24
months at 25°C).
Example 3.8 (pH variation): No significant pH variation was observed upon storage at any of
the tested temperatures, for all strengths (See Table 11) (up to 6 months at 40°C and up to
24 months at 25°C).
Example 3.9 (osmolality variation): No significant osmolality variation was observed upon
storage at any of the tested temperatures, for all strengths (See Table 12) (up to 6 months at
40°C and up to 24 months at 25°C).
