Definitions

  • the present invention relates to a method for the production of an antiangiogenic and/or vascular permeability reducing effect in a warm-blooded animal such as a human which is optionally being treated with ionising radiation, particularly a method for the treatment of a cancer, particularly a cancer involving a solid tumour, which comprises the administration of ZD6474 in combination with AZD2171; to a pharmaceutical composition comprising ZD6474 and AZD2171; to a combination product comprising ZD6474 and AZD2171 for use in a method of treatment of a human or animal body by therapy; to a kit comprising ZD6474 and AZD2171 ; to the use of ZD6474 and AZD2171 in the manufacture of a medicament for use in the production of an antiangiogenic and/or vascular permeability reducing effect in a warm-blooded animal such as a human which is optionally being treated with ionising radiation.
  • Normal angiogenesis plays an important role in a variety of processes including embryonic development, wound healing and several components of female reproductive function.
  • Undesirable or pathological angiogenesis has been associated with disease states including diabetic retinopathy, psoriasis, cancer, rheumatoid arthritis, atheroma, Kaposi's sarcoma and haemangioma (Fan et al, 1995, Trends Pharmacol. Sci. 16: 57-66; Folkman, 1995, Nature Medicine 1 : 27-31).
  • vascular permeability is thought to play a role in both normal and pathological physiological processes (Cullinan-Bove et al, 1993, Endocrinology 133: 829-837; Senger et al, 1993, Cancer and Metastasis Reviews, 12: 303- 324).
  • Several polypeptides with in vitro endothelial cell growth promoting activity have been identified including, acidic and basic fibroblast growth factors (aFGF & bFGF) and vascular endothelial growth factor (VEGF).
  • aFGF & bFGF acidic and basic fibroblast growth factors
  • VEGF vascular endothelial growth factor
  • VEGF is an important stimulator of both normal and pathological angiogenesis (Jakeman et al, 1993, Endocrinology, 133: 848-859; Kolch et al, 1995, Breast Cancer Research and Treatment, 36:139-155) and vascular permeability (Connolly et al, 1989, J. Biol. Chem. 264: 20017- 20024).
  • Antagonism of VEGF action by sequestration of VEGF with antibody can result in inhibition of tumour growth (Kim et al, 1993, Nature 362: 841-844).
  • Receptor tyrosine kinases are important in the transmission of biochemical signals across the plasma membrane of cells.
  • transmembrane molecules characteristically consist of an extracellular ligand-binding domain connected through a segment in the plasma membrane to an intracellular tyrosine kinase domain. Binding of ligand to the receptor results in stimulation of the receptor-associated tyrosine kinase activity which leads to phosphorylation of tyrosine residues on both the receptor and other intracellular molecules. These changes in tyrosine phosphorylation initiate a signalling cascade leading to a variety of cellular responses. To date, at least nineteen distinct RTK subfamilies, defined by amino acid sequence homology, have been identified.
  • FIt-I fms-like tyrosine kinase receptor
  • KDR kinase insert domain-containing receptor
  • Flt-4 fms-like tyrosine kinase receptor
  • Two of these related RTKs, FIt-I and KDR have been shown to bind VEGF with high affinity (De Vries et al, 1992, Science 255: 989-991; Terman et al, 1992, Biochem. Biophys. Res. Comm. 1992, 187: 1579-1586). Binding of VEGF to these receptors expressed in heterologous cells has been associated with changes in the tyrosine phosphorylation status of cellular proteins and calcium fluxes.
  • VEGF is a key stimulus for vasculogenesis and angiogenesis.
  • This cytokine induces a vascular sprouting phenotype by inducing endothelial cell proliferation, protease expression and migration, and subsequent organisation of cells to form a capillary tube (Keck, P.J., Hauser, S.D., Rrivi, G., Sanzo, K., Warren, T., Feder, J., and Connolly, D.T., Science (Washington DC), 246: 1309-1312, 1989; Lamoreaux, W.J., Fitzgerald, M.E., Reiner, A., Hasty, K.A., and Charles, S.T., Microvasc.
  • VEGF vascular permeability
  • ZD6474 is also known as vandetanib and as ZACTIMATM (AstraZeneca).
  • ZD6474 falls within the broad general disclosure of WO 98/13354 and is exemplified in WO 01/32651.
  • ZD6474 is a potent inhibitor of VEGF RTK and also has some activity against EGF RTK.
  • ZD6474 has been shown to elicit broad-spectrum anti- tumour activity in a range of models following once-daily oral administration (Wedge SR, Ogilvie DJ, Dukes M, et al. ZD6474 inhibits vascular endothelial growth factor signaling, angiogenesis, and tumour growth following oral administration. Cancer Res 2002;62:4645- 4655).
  • WO 98/13354 and WO 01/32651 then go on to describe examples of such conjoint treatment including surgery, radiotherapy and various types of chemotherapeutic agent.
  • AZD2171 is described in WO 00/47212 and is Example 240 therein.
  • AZD2171 is 4-(4-fluoro-2-methyl- lH-indol-5-yloxy)-6-methoxy-7-(3-(pyrrolidin-l-yl)propoxy)quinazoline:
  • AZD2171 is also known as cediranib and as RECENTINTM (AstraZeneca).
  • AZD2171 shows excellent activity in the in vitro (a) enzyme and (b) FfUVEC assays that are described in WO 00/47212 (pages 80-83).
  • the AZD2171 IC 50 values for inhibition of isolated KDR (VEGFR-2), FIt-I (VEGFR-I) and Flt-4 (VEGFR-3) tyrosine kinase activities in the enzyme assay were ⁇ 2 nM, 5 + 2 nM and ⁇ 3 nM respectively.
  • AZD2171 inhibits VEGF-stimulated endothelial cell proliferation potently (IC 50 value of 0.4 + 0.2 nM in the HUVEC assay), but does not inhibit basal endothelial cell proliferation appreciably at a > 1250 fold greater concentration (IC 50 value is > 500 nM).
  • the growth of a Calu-6 tumour xenograft in the in vivo solid tumour model described in WO 00/47212 (page 83) was inhibited by 49% , 69% and 91% following 28 days of once-daily oral treatment with 1.5, 3 and 6 mg/kg/day AZD2171 respectively (P ** ⁇ 0.01, P *** ⁇ 0.0001; one- tailed t test).
  • AZD2171 has been shown to elicit broad- spectrum anti-tumour activity in a range of models following once-daily oral administration, (Wedge et al., 2005, Cancer Research 65: 4389-4440).
  • WO 00/47212 then goes on to describe examples of such conjoint treatment including surgery, radiotherapy and various types of chemotherapeutic agent.
  • Anti-cancer effects of a method of treatment of the present invention include, but are not limited to, anti-tumour effects, the response rate, the time to disease progression and the survival rate.
  • Anti-tumour effects of a method of treatment of the present invention include but are not limited to, inhibition of tumour growth, tumour growth delay, regression of tumour, shrinkage of tumour, increased time to regrowth of tumour on cessation of treatment, slowing of disease progression. It is expected that when a method of treatment of the present invention is administered to a warm-blooded animal such as a human, in need of treatment for cancer, said method of treatment will produce an effect, as measured by, for example, one or more of: the extent of the anti-tumour effect, the response rate, the time to disease progression and the survival rate.

Description

COMBINATION THERAPY 038
The present invention relates to a method for the production of an antiangiogenic and/or vascular permeability reducing effect in a warm-blooded animal such as a human which is optionally being treated with ionising radiation, particularly a method for the treatment of a cancer, particularly a cancer involving a solid tumour, which comprises the administration of ZD6474 in combination with AZD2171; to a pharmaceutical composition comprising ZD6474 and AZD2171; to a combination product comprising ZD6474 and AZD2171 for use in a method of treatment of a human or animal body by therapy; to a kit comprising ZD6474 and AZD2171 ; to the use of ZD6474 and AZD2171 in the manufacture of a medicament for use in the production of an antiangiogenic and/or vascular permeability reducing effect in a warm-blooded animal such as a human which is optionally being treated with ionising radiation.
Normal angiogenesis plays an important role in a variety of processes including embryonic development, wound healing and several components of female reproductive function. Undesirable or pathological angiogenesis has been associated with disease states including diabetic retinopathy, psoriasis, cancer, rheumatoid arthritis, atheroma, Kaposi's sarcoma and haemangioma (Fan et al, 1995, Trends Pharmacol. Sci. 16: 57-66; Folkman, 1995, Nature Medicine 1 : 27-31). Alteration of vascular permeability is thought to play a role in both normal and pathological physiological processes (Cullinan-Bove et al, 1993, Endocrinology 133: 829-837; Senger et al, 1993, Cancer and Metastasis Reviews, 12: 303- 324). Several polypeptides with in vitro endothelial cell growth promoting activity have been identified including, acidic and basic fibroblast growth factors (aFGF & bFGF) and vascular endothelial growth factor (VEGF). By virtue of the restricted expression of its receptors, the growth factor activity of VEGF, in contrast to that of the FGFs, is relatively specific towards endothelial cells. Recent evidence indicates that VEGF is an important stimulator of both normal and pathological angiogenesis (Jakeman et al, 1993, Endocrinology, 133: 848-859; Kolch et al, 1995, Breast Cancer Research and Treatment, 36:139-155) and vascular permeability (Connolly et al, 1989, J. Biol. Chem. 264: 20017- 20024). Antagonism of VEGF action by sequestration of VEGF with antibody can result in inhibition of tumour growth (Kim et al, 1993, Nature 362: 841-844). Receptor tyrosine kinases (RTKs) are important in the transmission of biochemical signals across the plasma membrane of cells. These transmembrane molecules characteristically consist of an extracellular ligand-binding domain connected through a segment in the plasma membrane to an intracellular tyrosine kinase domain. Binding of ligand to the receptor results in stimulation of the receptor-associated tyrosine kinase activity which leads to phosphorylation of tyrosine residues on both the receptor and other intracellular molecules. These changes in tyrosine phosphorylation initiate a signalling cascade leading to a variety of cellular responses. To date, at least nineteen distinct RTK subfamilies, defined by amino acid sequence homology, have been identified. One of these subfamilies is presently comprised by the fms-like tyrosine kinase receptor, FIt-I (also referred to as VEGFR-I), the kinase insert domain-containing receptor, KDR (also referred to as VEGFR-2 or FIk-I), and another fms-like tyrosine kinase receptor, Flt-4. Two of these related RTKs, FIt-I and KDR, have been shown to bind VEGF with high affinity (De Vries et al, 1992, Science 255: 989-991; Terman et al, 1992, Biochem. Biophys. Res. Comm. 1992, 187: 1579-1586). Binding of VEGF to these receptors expressed in heterologous cells has been associated with changes in the tyrosine phosphorylation status of cellular proteins and calcium fluxes.
VEGF is a key stimulus for vasculogenesis and angiogenesis. This cytokine induces a vascular sprouting phenotype by inducing endothelial cell proliferation, protease expression and migration, and subsequent organisation of cells to form a capillary tube (Keck, P.J., Hauser, S.D., Rrivi, G., Sanzo, K., Warren, T., Feder, J., and Connolly, D.T., Science (Washington DC), 246: 1309-1312, 1989; Lamoreaux, W.J., Fitzgerald, M.E., Reiner, A., Hasty, K.A., and Charles, S.T., Microvasc. Res., 55: 29-42, 1998; Pepper, M.S., Montesano, R., Mandroita, S.J., Orci, L. and Vassalli, J.D., Enzyme Protein, 49: 138- 162, 1996.). In addition, VEGF induces significant vascular permeability (Dvorak, H. F., Detmar, M., Claffey, K.P., Nagy, J.A., van de Water, L., and Senger, D.R., (Int. Arch. Allergy Immunol, 107: 233-235, 1995; Bates, D.O., Heald, R.I., Curry, F.E. and Williams, B. J. Physiol. (Lond.), 533: 263-272, 2001), promoting formation of a hyper-permeable, immature vascular network which is characteristic of pathological angiogenesis. It has been shown that activation of KDR alone is sufficient to promote all of the major phenotypic responses to VEGF, including endothelial cell proliferation, migration, and survival, and the induction of vascular permeability (Meyer, M., Clauss, M., Lepple- Wienhues, A., Waltenberger, J., Augustin, H. G., Ziche, M., Lanz, C, Bϋttner, M., Rziha, H- J., and Dehio, C, EMBO J., 18: 363-374, 1999; Zeng, H., Sanyal, S. and Mukhopadhyay, D., J. Biol. Chem., 276: 32714-32719, 2001; Gille, H., Kowalski, J., Li, B., LeCouter, J., Moffat, B, Zioncheck, T.F., Pelletier, N. and Ferrara, N., J. Biol. Chem., 276: 3222-3230, 2001).
Quinazoline derivatives which are inhibitors of VEGF receptor tyrosine kinase are described in International Patent Applications Publication Nos. WO 98/13354 and WO 01/32651. In WO 98/13354 and WO 01/32651 compounds are described which possess activity against VEGF receptor tyrosine kinase (VEGF RTK) whilst possessing some activity against epidermal growth factor (EGF) receptor tyrosine kinase (EGF RTK).

ZD6474
ZD6474 is also known as vandetanib and as ZACTIMA™ (AstraZeneca).
ZD6474 falls within the broad general disclosure of WO 98/13354 and is exemplified in WO 01/32651. ZD6474 is a potent inhibitor of VEGF RTK and also has some activity against EGF RTK. ZD6474 has been shown to elicit broad-spectrum anti- tumour activity in a range of models following once-daily oral administration (Wedge SR, Ogilvie DJ, Dukes M, et al. ZD6474 inhibits vascular endothelial growth factor signaling, angiogenesis, and tumour growth following oral administration. Cancer Res 2002;62:4645- 4655).
In WO 98/13354 and WO 01/32651 it is stated that compounds of their inventions: "may be applied as a sole therapy or may involve, in addition to a compound of the invention, one or more other substances and/or treatments. Such conjoint treatment may be achieved by way of the simultaneous, sequential or separate administration of the individual components of the treatment."
WO 98/13354 and WO 01/32651 then go on to describe examples of such conjoint treatment including surgery, radiotherapy and various types of chemotherapeutic agent.
Nowhere in WO 98/13354 and WO 01/32651 do they suggest the combination of a compound of the invention and AZD2171 for the treatment of any disease state including cancer.
Nowhere in WO 98/13354 and WO 01/32651 is the specific combination of ZD6474 and AZD2171 suggested.
Nowhere in WO 98/13354 and WO 01/32651 does it state that use of any compound of the invention therein with other treatments will produce surprisingly beneficial effects.
Quinazoline derivatives which are inhibitors of VEGF receptor tyrosine kinase are described in International Patent Application Publication No. WO 00/47212. AZD2171 is described in WO 00/47212 and is Example 240 therein. AZD2171 is 4-(4-fluoro-2-methyl- lH-indol-5-yloxy)-6-methoxy-7-(3-(pyrrolidin-l-yl)propoxy)quinazoline:

AZD2171
AZD2171 is also known as cediranib and as RECENTIN™ (AstraZeneca).
AZD2171 shows excellent activity in the in vitro (a) enzyme and (b) FfUVEC assays that are described in WO 00/47212 (pages 80-83). The AZD2171 IC50 values for inhibition of isolated KDR (VEGFR-2), FIt-I (VEGFR-I) and Flt-4 (VEGFR-3) tyrosine kinase activities in the enzyme assay were <2 nM, 5 + 2 nM and <3 nM respectively. AZD2171 inhibits VEGF-stimulated endothelial cell proliferation potently (IC50 value of 0.4 + 0.2 nM in the HUVEC assay), but does not inhibit basal endothelial cell proliferation appreciably at a > 1250 fold greater concentration (IC50 value is > 500 nM). The growth of a Calu-6 tumour xenograft in the in vivo solid tumour model described in WO 00/47212 (page 83) was inhibited by 49% , 69% and 91% following 28 days of once-daily oral treatment with 1.5, 3 and 6 mg/kg/day AZD2171 respectively (P**<0.01, P***<0.0001; one- tailed t test). AZD2171 has been shown to elicit broad- spectrum anti-tumour activity in a range of models following once-daily oral administration, (Wedge et al., 2005, Cancer Research 65: 4389-4440).
In WO 00/47212 it is stated that compounds of the invention: "may be applied as a sole therapy or may involve, in addition to a compound of the invention, one or more other substances and/or treatments.

According to a further aspect of the present invention there is provided a therapeutic combination treatment comprising the administration of an effective amount of ZD6474 or a pharmaceutically acceptable salt thereof, optionally together with a pharmaceutically acceptable excipient or carrier, and the administration of an effective amount of AZD2171 or a pharmaceutically acceptable salt thereof, optionally together with a pharmaceutically acceptable excipient or carrier and the administration of an effective amount of ionising radiation, to a warm-blooded animal such as a human in need of such therapeutic treatment wherein the ZD6474, AZD2171 and ionising radiation may be administered simultaneously, sequentially or separately and in any order.
A warm-blooded animal such as a human which is being treated with ionising radiation means a warm-blooded animal such as a human which is treated with ionising radiation before, after or at the same time as the administration of a medicament or combination treatment comprising ZD6474 and AZD2171. For example said ionising radiation may be given to said warm-blooded animal such as a human within the period of a week before to a week after the administration of a medicament or combination treatment comprising ZD6474 and AZD2171. This means that ZD6474, AZD2171 and ionising radiation may be administered separately or sequentially in any order, or may be administered simultaneously. The warm-blooded animal may experience the effect of each of ZD6474, AZD2171 and radiation simultaneously.
According to one aspect of the present invention the ionising radiation is administered before one of ZD6474 and AZD2171 or after one of ZD6474 and AZD2171.
According to one aspect of the present invention the ionising radiation is administered before both ZD6474 and AZD2171 or after both ZD6474 and AZD2171.

According to another aspect of the present invention the effect of a method of treatment of the present invention is expected to be greater than the addition of the effects of each of the components of said treatment used alone, that is, of each of ZD6474 and AZD2171 used alone or of each of ZD6474, AZD2171 and ionising radiation used alone.
According to another aspect of the present invention the effect of a method of treatment of the present invention is expected to be a synergistic effect.
According to the present invention a combination treatment is defined as affording a synergistic effect if the effect is therapeutically superior, as measured by, for example, the extent of the response, the response rate, the time to disease progression or the survival period, to that achievable on dosing one or other of the components of the combination treatment at its conventional dose. For example, the effect of the combination treatment is synergistic if the effect is therapeutically superior to the effect achievable with ZD6474 or AZD2171 or ionising radiation alone. Further, the effect of the combination treatment is synergistic if a beneficial effect is obtained in a group of patients that does not respond (or responds poorly) to ZD6474 or AZD2171 or ionising radiation alone. In addition, the effect of the combination treatment is defined as affording a synergistic effect if one of the components is dosed at its conventional dose and the other component(s) is/are dosed at a reduced dose and the therapeutic effect, as measured by, for example, the extent of the response, the response rate, the time to disease progression or the survival period, is equivalent to that achievable on dosing conventional amounts of the components of the combination treatment. In particular, synergy is deemed to be present if the conventional dose of ZD6474 or AZD2171 or ionising radiation may be reduced without detriment to one or more of the extent of the response, the response rate, the time to disease progression and survival data, in particular without detriment to the duration of the response, but with fewer and/or less troublesome side-effects than those that occur when conventional doses of each component are used.
As stated above the combination treatments of the present invention as defined herein are of interest for their antiangiogenic and/or vascular permeability effects. Angiogenesis and/or an increase in vascular permeability is present in a wide range of disease states including cancer (including leukaemia, multiple myeloma and lymphoma), diabetes, psoriasis, rheumatoid arthritis, Kaposi's sarcoma, haemangioma, acute and chronic nephropathies, atheroma, arterial restenosis, autoimmune diseases, acute inflammation, asthma, lymphoedema, endometriosis, dysfunctional uterine bleeding and ocular diseases with retinal vessel proliferation including age-related macular degeneration.

Preferably ZD6474 is administered orally. Preferably AZD2171 is administered orally.
In general the compositions described herein may be prepared in a conventional manner using conventional excipients. The compositions of the present invention are advantageously presented in unit dosage form.
ZD6474 will normally be administered to a warm-blooded animal at a unit dose within the range 10-500mg per square metre body area of the animal, for example approximately 0.3-15mg/kg in a human. A unit dose in the range, for example, 0.3- 15mg/kg, preferably 0.5-5mg/kg is envisaged and this is normally a therapeutically-effective dose. A unit dosage form such as a tablet or capsule will usually contain, for example 25-500mg of active ingredient. Preferably a daily dose in the range of 0.5-5mg/kg is employed.
AZD2171 will normally be administered to a warm-blooded animal at a unit dose within the range l-50mg per square metre body area of the animal, for example approximately 0.03-1.5 mg/kg in a human. A unit dose in the range, for example, 0.01- 1.5mg/kg, preferably 0.03-0.5mg/kg is envisaged and this is normally a therapeutically-effective dose. A unit dosage form such as a tablet or capsule will usually contain, for example l-50mg of active ingredient. Preferably a daily dose in the range of 0.03-0.5mg/kg is employed.
The dosages and schedules may vary according to the particular disease state and the overall condition of the patient. Dosages and schedules may also vary if, in addition to a combination treatment of the present invention, one or more additional chemotherapeutic agents is/are used. Scheduling can be determined by the practitioner who is treating any particular patient.
Radiotherapy may be administered according to the known practices in clinical radiotherapy. The dosages of ionising radiation will be those known for use in clinical radiotherapy. The radiation therapy used will include for example the use of γ-rays, X- rays, and/or the directed delivery of radiation from radioisotopes. Other forms of DNA damaging factors are also included in the present invention such as microwaves and UV- irradiation. For example X-rays may be dosed in daily doses of 1.8-2.0Gy, 5 days a week for 5-6 weeks. Normally a total fractionated dose will lie in the range 45-60Gy. Single larger doses, for example 5-10Gy may be administered as part of a course of radiotherapy. Single doses may be administered intraoperatively. Hyperfractionated radiotherapy may be used whereby small doses of X-rays are administered regularly over a period of time, for example 0.1 Gy per hour over a number of days. Dosage ranges for radioisotopes vary widely, and depend on the half- life of the isotope, the strength and type of radiation emitted, and on the uptake by cells.
The size of the dose of each therapy which is required for the therapeutic or prophylactic treatment of a particular disease state will necessarily be varied depending on the host treated, the route of administration and the severity of the illness being treated. Accordingly the optimum dosage may be determined by the practitioner who is treating any particular patient. For example, it may be necessary or desirable to reduce the above- mentioned doses of the components of the combination treatments in order to reduce toxicity.
The present invention relates to combinations of AZD2171 or a salt of AZD2171 with ZD6474 or a salt of ZD6474.
Salts of ZD6474 for use in pharmaceutical compositions will be pharmaceutically acceptable salts, but other salts may be useful in the production of ZD6474 and its pharmaceutically acceptable salts. Such salts may be formed with an inorganic or organic base which affords a pharmaceutically acceptable cation. Such salts with inorganic or organic bases include for example an alkali metal salt, such as a sodium or potassium salt, an alkaline earth metal salt such as a calcium or magnesium salt, an ammonium salt or for example a salt with methylamine, dimethylamine, trimethylamine, piperidine, morpholine or tris-(2-hydroxyethyl)amine.
ZD6474 may be synthesised according to any of the known processes for making ZD6474. For example ZD6474 may be made according to any of the processes described in WO 01/32651; for example those described in Examples 2(a), 2(b) and 2(c) of WO 01/32651. For example ZD6474 may be made according to any of the processes described in WO 07/036713.
Salts of AZD2171 for use in pharmaceutical compositions will be pharmaceutically acceptable salts, but other salts may be useful in the production of AZD2171 and its pharmaceutically acceptable salts. Pharmaceutically acceptable salts may, for example, include acid addition salts. Such acid addition salts include for example salts with inorganic or organic acids affording pharmaceutically acceptable anions such as with hydrogen halides or with sulphuric or phosphoric acid, or with trifluoroacetic, citric or maleic acid. In addition pharmaceutically acceptable salts may be formed with an inorganic or organic base which affords a pharmaceutically acceptable cation. Such salts with inorganic or organic bases include for example an alkali metal salt, such as a sodium or potassium salt and an alkaline earth metal salt such as a calcium or magnesium salt. A preferred salt is AZD2171 maleate which is described in International Patent Application Publication No. WO 05/061488.
AZD2171 may be synthesised according to the processes described in WO 00/47212, in particular those described in Example 240 of WO 00/47212.
AZD2171 maleate salt may be synthesised according to the processes described in WO 05/061488. For example AZD2171 and AZD2171 maleate salt may be synthesised according to the processes described in WO 08/053221.
The following tests may be used to demonstrate the activity of ZD6474 in combination with AZD2171. A431 human vulval epidermoid carcinoma xenograft model Experiments were conducted on female athymic mice (Swiss nu/nu genotype, >6 weeks of age). A431 human tumour xenografts were established in the experimental mice by injecting 1 x 107 cells per mouse, mixed in a ratio of 1 : 1 with Matrigel, subcutaneous Iy in the dorsal flank in a volume of lOOμl. Tumour volumes were assessed at least twice weekly by bilateral Vernier calliper measurements. Mice were randomised into treatment groups when the mean tumour volume reached 0.2-0.4cm3 (day 0). Following randomisation, mice were treated with either drug vehicle (Control) or ZD6474 (12.5 mg/kg/day) administered orally (p.o.) once daily from day 0 until end of the study, or with AZD2171 (0.75 mg/kg/day) administered orally (p.o.) once daily from day 0 until end of the study. An additional group of animals received a combination of ZD6474 and AZD2171, using the same doses and schedules as used for single agent treatment.
Tumour growth inhibition from the start of treatment was assessed by comparison of the differences in tumour volume (median and geometric mean) between control and treated groups. The effects of combination treatment were assessed by comparing any effect on tumour growth in the group of animals receiving ZD6474 plus AZD2171 with tumour growth in the groups where animals received single agent therapy alone.
An analogous experiment may be used to look at the combination of ZD6474 and AZD2171 with ionising radiation.
An analogous experiment may be used to look at the combination of ZD6474 and AZD2171 and an EGF RTK.
Example 1
Following the methodology above, mice were randomised into four treatment groups 7 days after tumour cell implantation (mean tumor start size 0.23 cm3). Mice were treated with daily oral doses of AZD2171 or ZD6474 either alone (Groups II and III), or in combination (Group IV). Control animals (Group I) received drug vehicles alone. Data shown are tumour volumes 10 days after randomisation when control tumours reached approximately 1.0 cm3. Table 1

1NS (Rank-Sum test compared with treatment group I) 2P<0.001 (Rank-Sum test compared with treatment group I) 3P<0.001 (Rank-Sum test compared with treatment group II) 4P=0.01 (Rank-Sum test compared with treatment group III)
The data are shown graphically in Figure 1. The data show that the combination of ZD6474 and AZD2171 produces a statistically significantly greater anti-tumour effect than either agent alone.
