    Pharmaceutical Compositions

    [0239] Antibodies and radioimmunoconjugates are usually applied in the treatment of diseases formulated in pharmaceutical compositions.

    [0240] Such compositions are optimized for parameters such as physiological tolerance and shelf-life.

    [0241] Thus, in one embodiment of the present invention is the radioimmunoconjugates and/or antibodies of the present invention formulated as a pharmaceutical composition.

    [0242] An embodiment of the present invention relates to a pharmaceutical composition as described above, further comprising one or more additional therapeutic agents.

    [0243] In another embodiment of the present invention are said one or more additional therapeutic agents selected from agents that induce apoptosis.

    [0244] Usually is an important element of a pharmaceutical composition a buffer solution, which to a substantial degree maintain the chemical integrity of the radioimmunoconjugate and/or antibody and is being physiologically acceptable for infusion into patients.

    [0245] In one embodiment of the present invention the pharmaceutical composition comprises one or more pharmaceutically acceptable carriers and/or adjuvants.

    [0246] Acceptable pharmaceutical carriers include but are not limited to non-toxic buffers, fillers, isotonic solutions, etc. More specifically, the pharmaceutical carrier can be but are not limited to normal saline (0.9%), half-normal saline, Ringer's lactate, 5%) Dextrose, 3.3% Dextrose/0.3% Saline. The physiologically acceptable carrier can contain a radiolytic stabilizer, e.g., ascorbic acid, which protect the integrity of the radiopharmaceutical during storage and shipment.

    [0247] In one embodiment of the present invention are lilotomab and Betalutin formulated as indicated in Tables 1 and 2 in Example 1.

    [0248] Preferably are sodium dihydrogen phosphate monohydrate, sodium chloride, recombinant human albumin, sodium ascorbate, diethylenetriamine pentaacetic acid (DTPA) and sodium hydroxide used as excipients in the formulation buffer.

    [0249] Preferably is phosphate included in the formulation buffer to maintain the pH of the finished product during the shelf life.

    [0250] Preferably is recombinant human albumin included in the formulation buffer as a stabilizer for the lilotomab satetraxetan conjugate. The albumin also acts as a radioprotectant. Recombinant human albumin structurally identical to human serum albumin derived from yeast is used. No human- or animal-derived raw material is involved in its manufacture. The excipient is well known and is used in pharmaceutical products for human use.

    [0251] Preferably is sodium ascorbate included in the formulation to act as a radiolytic scavenger to ensure the stability of Betalutin over the shelf-life of the product.

    [0252] Preferably is DTPA introduced as an excipient in the Betalutin formulation to chelate any free .sup.177Lu.sup.3+ ions and to reroute this impurity from accumulation in the bone to rapid renal clearance (Li et al 2001, Breeman et al 2003). Betalutin contains 9.3 μmol DTPA in 12 mL, while the maximum amount of no-carrier added (n.c.a) .sup.177Lu.sup.3+ (>3,000 GBq/mg) applied (6.9 GBq) corresponds to less than 15 nmol Lu ions. This gives a more than 1000-fold molar excess of DTPA over Lu.sup.3+ ions. Furthermore, when taking into account that the majority of the Lu3+ ions 95%) is chelated to lilotomab satetraxetan, the molar excess is almost 100,000-fold. DTPA is therefore expected to chelate all free .sup.177Lu.sup.3+ ions quantitatively and .sup.177Lu-DTPA is thus specified as radiochemical impurity in the specification.

    [0253] Preferably is the formulation buffer an aqueous solution with pH 6.9 to 7.0 and thus no incompatibilities between the drug substance and the formulation buffer are expected.

    [0254] One embodiment of the present invention comprises the pharmaceutical composition of the present invention and one or more additional antibodies or radioimmunoconjugates.

    [0255] As aspect of the present invention relates to a pharmaceutical composition comprising (per mL): 0.75 mg Lutetium (.sup.177Lu) lilotomab satetraxetan, 0.46 mg Ammonium acetate, and Trace amounts of HCl.sub.3.

    [0256] Another aspect of the present invention relates to a pharmaceutical composition comprising (per mL): 30.86 mg Sodium ascorbate, 0.31 mg DTPA, 0.17 mg NaOH, 60.82 mg Recombinant human albumin, 3.32 mg Sodium dihydrogen phosphate monohydrate, and 4.34 mg Sodium chloride with the pH is adjusted to 6.9-7.0.

    [0257] A further aspect of the present invention relates to a pharmaceutical composition comprising; 14% of the pharmaceutical composition comprising (per mL): 0.75 mg Lutetium (.sup.177Lu) lilotomab satetraxetan, 0.46 mg Ammonium acetate, and Trace amounts of HCl.sup.3, and 86% of the pharmaceutical composition comprising (per mL): 30.86 mg Sodium ascorbate, 0.31 mg DTPA, 0.17 mg NaOH, 60.82 mg Recombinant human albumin, 3.32 mg Sodium dihydrogen phosphate monohydrate, and 4.34 mg Sodium chloride with the pH is adjusted to 6.9-7.0.

    [0258] The present invention also relates to the pharmaceutical compositions of the present examples, as well as the dosage administration patterns presented herein. This includes the use of the pharmaceutical compositions of the present invention for use in the treatment of Non-Hodgkin lymphoma.

    Cancer Types

    [0259] The person in need of treatment with .sup.177Lu-lilotomab satetraxetan is suffering from a CD37 related disease, typically a B-cell lymphoma such as Non-Hodgkin lymphoma (NHL).

    [0260] NHL is a group of blood cancers that includes all types of lymphoma except Hodgkin's lymphomas. Symptoms include enlarged lymph nodes, fever, night sweats, weight loss, and feeling tired. Other symptoms may include bone pain, chest pain, or itchiness. Some forms are slow growing while others are fast growing.

    [0261] There are several types of NHL. Thus, another embodiment of the present invention relates to the lymphoma being a subtype selected from the group consisting of follicular grade I-IIIA, marginal zone, small lymphocytic, lymphoplasmacytic, Diffuse large B-cell lymphoma, and mantle cell.

    [0262] In an embodiment of the present invention is the NHL cancer follicular grade I-IIIA.

    [0263] In an embodiment of the present invention is the NHL cancer marginal zone.

    [0264] In an embodiment of the present invention is the NHL cancer small lymphocytic.

    [0265] In an embodiment of the present invention is the NI-L cancer lymphoplasmacytic.

    [0266] In an embodiment of the present invention is the NHL cancer mantle cell.

    [0267] In an embodiment of the present invention is the NHL cancer AML.

    [0268] In an embodiment of the present invention is the NHL cancer CLL

    [0269] In an embodiment of the present invention is the NHL cancer Diffuse Large B-cell lymphoma (DLBCL).

    [0270] Some cell types of leukemia also express the CD37 antigen. Thus, another embodiment of the present invention relates to leukemia of the subtypes chronic lymphocytic leukemia and acute myelogen leukemia. More specifically the present invention relates to AML with 11Q23/MLL translocation. Thus, in one embodiment of the present invention is the NHL cancer AML with 11Q23/MLL translocation.

    General

    [0271] It should be understood that any feature and/or aspect discussed above in connections with the compounds and particles according to the invention apply by analogy to the methods and applications described herein.

    [0272] The following figures and examples are provided below to illustrate the present invention. They are intended to be illustrative and are not to be construed as limiting in any way.

    EXAMPLES

    Example 1—Clinical Study on .SUP.177.Lu-Lilotomab Satetraxetan

    Materials and Methods

    [0273] Betalutin is an antibody-radionuclide-conjugate (ARC) composed of the radioisotope lutetium-177, the linker benzyl-DOTA and the murine anti-CD37 IgG1 antibody, lilotomab. The active moiety is the beta particle emitting nuclide .sup.177Lu. Lutetium-177 has physical half-life of 6.7 days. The antibody lilotomab recognises epitopes on the CD37 antigen, which is abundant on the cell surface of tumours of B-cell origin, including NHL. Betalutin is prepared as a solution for intravenous administration. 1 mg/ml lilotomab antibody will be used, between 7 to 20 mg lilotomab antibody per patient. The amount of lutetium (.sup.177Lu)-lilotomab satetraxetan injected per patient will depend on dose level and patient's weight; however, the dose is capped for patients who weigh more than 130 kg (patients heavier than 130 kg will receive the dose for a 130 kg patient). Betalutin are supplied in vials containing a ready to use solution.

    [0274] The investigational medicinal product will be referred to as Betalutin or lutetium (.sup.177Lu)-lilotomab satetraxetan in the protocol.

    [0275] Rituximab (MabThera) is used as pre-treatment. Rituximab, a chimeric anti-CD20 antibody will be used to clear the circulating normal peripheral B-lymphocytes in the blood and in the spleen before administrating CD37 targeting Betalutin. This may secure better access for Betalutin to less accessible compartments such as lymph nodes and larger tumour masses. Rituximab targets CD20 and will not block the binding of Betalutin CD37 on the B-lymphocytes or tumour cells. Betalutin contains a murine monoclonal antibody which has been shown from in vitro analysis to bind to the human Fc-γ receptor Ha. While rituximab binds to CD20 it also binds to the Fc-γ receptor Ha and if administered just prior to Betalutin may therefore inhibit the binding of Betalutin to this receptor and improve its biodistribution. Arm 3 has therefore been included in the study via a protocol amendment to test the ability of rituximab to improve the biodistribution of Betalutin. This improved biodistribution may reduce the incidence of myleosuppressive adverse events by decreasing the radioactivity in the bone marrow and spleen.

    [0276] In Phase I arms 1, 2, and Phase II, two intravenous infusions of 375 mg/m.sup.2 rituximab have been given, at 28 Days and 21 Days, before administration of Betalutin. In Phase I, arms 3, 4 and 5, one intravenous infusion of 375 mg/m.sup.2 rituximab have been given 14 days before, and in arms 3 and 5 an additional intravenous infusion of 375 mg/m.sup.2 rituximab will be given within 4 hours before Betalutin administration on Day 0. Pre-medication consisting of an antipyretic and antihistamine medication should be administered before infusion of rituximab. The types of pre-medication are in accordance with each hospital's routine, including any use of corticosteroids.

    [0277] Lilotomab is used as pre-dosing. The same antibody, lilotomab, as used in Betalutin, a murine anti-CD37 antibody, is used to block the binding on remaining B-cells, after rituximab treatment, in the lymphoid organs. One intravenous infusion of 40 mg lilotomab in arm 1, and 100 mg/m.sup.2 lilotomab in arm 4 and arm 5, is performed within 4 hours before administration of Betalutin (up to a maximum of 2.7 m.sup.2 for lilotomab in arm 4 and 5). Pre-medication consisting of an antipyretic and antihistamine medication should be administered before infusion of lilotomab.

    [0278] Betalutin is administered in a dose of 15-20 Mbq/kg. Arm 4 is 15 Mbq/kg.

    [0279] An example of administration pattern can be seen in FIG. 4 and the composition components are shown in tables 1 and 2.

    Results

    [0280] These results are the results of a phase I/II clinical study on humans.

    [0281] Platelet and neutrophil counts of arm 3 (rituximab predosing) and arm 4 (100 mg/m.sup.2 lilotomab predosing) show grade 3-4 toxicity of arm 3 and no toxicity of arm 4 (FIGS. 1 and 2).

    [0282] The PK profiles show a large separation between the treatment arms. Arm 1=40 mg lilotomab predosing, Arm 2=no predosing, Arm 3=rituximab predosing and Arm 4=100 mg/m.sup.2 lilotomab predosing (FIG. 3).

    Example 2—Clinical Study on .SUP.177.Lu-Lilotomab Satetraxetan

    Materials and Methods

    [0283] Materials and methods are the same as in Example 1.

    [0284] In Phase I arms 1, 2, and Phase II, two intravenous infusions of 375 mg/m2 rituximab have been given, at 28 Days and 21 Days, before administration of Betalutin (FIG. 5). In Phase I, arms 3 and 4, one intravenous infusion of 375 mg/m2 rituximab have been given 14 days before, and in arm 3 an additional intravenous infusion of 375 mg/m2 rituximab have been given within 4 hours before Betalutin administration on Day 0 (FIG. 5). Pre-medication consisting of an antipyretic and antihistamine medication should be administered before infusion of rituximab. The types of pre-medication are in accordance with each hospital's routine, including any use of corticosteroids.

    [0285] Lilotomab is used as pre-dosing. The same antibody, lilotomab, as used in Betalutin, a murine anti-CD37 antibody, is used to block the binding on remaining B-cells, after rituximab treatment, in the lymphoid organs. One intravenous infusion of 40 mg lilotomab in arm 1, and 100 mg/m2 lilotomab in arm 4, is performed within 4 hours before administration of Betalutin (up to a maximum of 2.7 m2 for lilotomab in arm 4 and 5). Pre-medication consisting of an antipyretic and antihistamine medication should be administered before infusion of lilotomab.

    [0286] Betalutin is administered in a dose of 15-20 MBq/kg.

    [0287] Examples of administration patterns can be seen in FIG. 5 and the composition components are shown in tables 1 and 2 of example 1.

    Results

    [0288] These results are the results of a phase I/II clinical study on humans.

    [0289] Platelet and neutrophil counts of patients in arm 1 (40 mg predosing), arm 2 (no predosing), arm 3 (rituximab predosing) and arm 4 (100 mg/m2 lilotomab predosing) show grade 3-4 toxicity of arm 2 and 3, less toxicity of arm 1 and no toxicity of arm 4 (FIGS. 5 and 6).

    [0290] The PK profiles show a large separation between the treatment arms. Arm 1=40 mg lilotomab predosing, Arm 2=no predosing, Arm 3=rituximab predosing and Arm 4=100 mg/m2 lilotomab predosing (FIG. 7).

    [0291] The mean values for platelets and neutrophils at nadir for 23 arm 1 patients were lower than the mean values for 3 arm 4 patients (FIG. 9).

    [0292] The dose limiting toxicity and number of grade 3 and 4 adverse events were lower for arm 4 than for arm 1 and highest for arm 2 (FIG. 10). The efficacy was equal for all arms (FIG. 11).

    Example 3—Pre-Dosing with Lilotomab Prior to Treatment with .SUP.177.Lu-Lilotomab Satetraxetan Significantly Increases the Ratio of Tumour to Red Marrow Absorbed Dose in Non-Hodgkin Lymphoma Patients

    Aim:

    [0293] Four different combinations of pre-dosing and pre-treatment have been investigated. All patients were pre-treated with different regimens of rituximab. Two arms included cold lilotomab pre-dosing (arm 1 and 4; 40 mg fixed and 100 mg/m.sup.2 Body Surface Area dosage, respectively) and two did not (arm 2 and 3). Patients received either 10, 15 or 20 MBq .sup.177Lu-lilotomab satetraxetan per kg body weight. Previously, we have shown that absorbed red marrow (RM) doses were lower in arm 1 vs arm 2, and that haematological toxicity was more severe for patients receiving higher RM doses. The aim of this work was to compare the ratios of tumour to RM absorbed doses between arm 1, 4 and non-pre-dosed patients (arm 2+3).

    Materials and Methods:

    [0294] A total of 16 patients were included for RM dosimetry, of these were 14 included for tumour dosimetry. A total of 35 tumours were included, 1 to 5 from each patient (mode 3). RM and mean tumour absorbed doses per administered activity were determined from multiple SPECT/CT-images for each patient. Two-sided student-t-tests were used for all statistical analyses.

    Results:

    [0295] The mean RM absorbed doses were 0.83, 0.91 and 1.39 mGy/MBq for arm 1, 4 and non-pre-dosing respectively. There was a significantly higher RM dose for non-pre-dosing compared to arm 1 (p=0.04), and arm 4 (p=0.05). Mean tumour absorbed doses were 1.62, 2.78 and 1.37 mGy/MBq for arm 1, 4 and non-pre-dosing respectively. Tumour doses were higher in arm 4 patients compared to patients without pre-dosing (p=0.04). Tumour doses in arm 1 were not significantly higher compared to non-pre-dosing (p=0.71). The mean tumour to RM absorbed dose ratios were 2.16, 3.93 and 1.07 for arm 1, 4 and non-pre-dosing respectively. Ratios were significantly higher in both arm 1 and 4 compared to non-pre-dosing (p=0.05 and p=0.04). No statistically significant difference between arm 1 and 4 was found for any parameters (p>=0.12).

    Conclusion:

    [0296] Pre-dosing with lilotomab has a mitigating effect on red marrow absorbed dose for .sup.177Lu-lilotomab satetraxetan patients, and increased amounts was found correlated with a higher tumour dose. Both pre-dosage levels significantly increased the tumour to RM absorbed dose ratio.

    Example 4—Efficacy and Hematological Toxicity of .SUP.177.Lu-Lilotomab Satetraxetan in Non-Hodgkin Lymphoma Patients

    Aim:

    [0297] Four different combinations of pre-dosing and pre-treatment have been investigated. All patients were pre-treated with different regimens of 375 mg/m.sup.2 rituximab. The patients were enrolled into four dose-escalation arms:

    [0298] Arm 1: .sup.177Lu-lilotomab satetraxetan+pre-dosing with 40 mg lilotomab (cold anti-CD37 Ab)

    [0299] Arm 2: .sup.177Lu-lilotomab satetraxetan without pre-dosing

    [0300] Arm 3: .sup.177Lu-lilotomab satetraxetan+pre-dosing with 375 mg/m2 rituximab

    [0301] Arm 4: .sup.177Lu-lilotomab satetraxetan+pre-dosing with 100 mg/m2 lilotomab

    [0302] Patients received either 10, 15 or 20 MBq .sup.177Lu-lilotomab satetraxetan per kg body weight. The aim of this work was to determine the therapeutic efficacy and hematological toxicity of each study arm.

    [0303] After finding the maximum tolerable dose (MTD), arm 1 was continued into a phase 2 part to evaluate efficacy in a larger data-set.

    Patients and Methods:

    [0304] The key eligibility criteria was: 1) Age≥18 with histologically confirmed relapsed indolent B-cell NHL (follicular grade I-IIIA, mantle cell, SLL, marginal zone, lymphoplasmacytic subtypes). 2) <25% bone marrow involvement. 3) Life expectancy months. 4) Platelet count>150×10.sup.9/L. 5) ANC≥1.5×10.sup.9/L. 6) No previous hematopoietic stem cell transplantation.

    [0305] Dose-limiting toxicities (DLTs) were assessed during the first 12 weeks. Incidence and severity of adverse events (AEs) according to common terminology criteria for adverse events (CTCAE) v4.0. Response assessments were conducted at 3, 6 (FDG PET-CT), 9, 12, 18, 24 and 36 months (CT) per the International Working Group (IWG) criteria for NHL.

    [0306] A total of 52 patients were included in the different arms and dose groups according to Table 3.

    TABLE-US-00003 TABLE 3 Distribution of patient in different study arms and dose groups 10 MBq/kg 15 MBq/kg 20 MBq/kg Total Arm 1 4 29 3 36 Arm 2 1 2 0 3 Arm 3 0 3 0 3 Arm 4 0 3 7 10 Total 5 27 10 52

    Safety

    [0307] Overall, .sup.177Lu-lilotomab satetraxetan was well-tolerated. The most common grade 3/4 adverse events were reversible thrombocytopenia and neutropenia. No grade 4 neutropenia/thrombocytopenia was observed with higher lilotomab pre-dosing and 100 mg/m.sup.2 gave a higher bone marrow protection than 40 mg (FIGS. 1, 2). Dose-limiting toxicities were prolonged but reversible neutropenia and thrombocytopenia (8 patients), and hematuria associated with thrombocytopenia (1 patient). The recommended dose for phase 2 expansion of .sup.177Lu-lilotomab satetraxetan in Arm 1 with a lilotomab pre-dose of 40 mg was 15 MBq/kg. Twenty-three patients were included in the current analysis (Table 3, arm 1, 15 MBq/kg). Arm 4, 20 MBq/kg was also selected for expansion into phase 2, but no patients have been included yet. SAEs occurred in 15 patients (25%). Treatment-emergent SAEs occurring in 2 or more patients were thrombocytopenia (n=2), atrial fibrillation (n=2), and lymphoma progression (n=2). Eighteen months after subsequent treatment with bendamustine (24 months after Betaluting), myelodysplastic syndrome (MDS) or acute myelogen leukemia (AML) was reported in 1 patient with prior alkylating agent exposure. There were no treatment-related deaths. Mean platelet count in Arms 1 and 4 for 15 and 20 MBq/kg 177Lu-lilotomab satetraxetan can be seen in FIG. 13 and mean neutrophil count in Arms 1 and 4 for 15 and 20 MBq/kg .sup.177Lu-lilotomab satetraxetan can be seen in FIG. 14.

    Efficacy

    [0308] Overall, objective responses were observed in 33 of 52 (63%) patients. 13 patients (25%) achieved a CR (Table 4).
