In some cases, a composition comprising an albumin nanoparticle / antibody complex provided herein (e.g., / anti-CD20 polypeptide antibody complex) can be administered to a mammal having lymphoma under conditions where the median time to progression of the mammalian population is at least 150 days (e.g., at least 155, 160, 163, 165 or 170 days).
[0034] An effective amount of a composition comprising an albumin nanoparticle / antibody complex provided herein (e.g., / anti-CD20 polypeptide antibody complex) can be any amount that reduces the rate of lymphoma progression, increases the progression-free survival, or increases the median time to progression without causing significant toxicity to the mammal. Generally, an effective amount of can be about 50 mg / m2 to about 150 mg / m 2 (e.g., about 80 mg / m 2 ), and an effective amount of an anti-CD20 polypeptide antibody such as rituximab can be from about 5 mg / kg to about 20 mg / kg (e.g., about 10 mg / kg or 375 mg / m 2 ). If a particular mammal fails to respond to a particular amount, then the dosage of the anti-CD20 polypeptide antibody can be increased, e.g., doubled. After receiving the higher concentration, the responsiveness of the mammal to both the treatment and toxic symptoms can be monitored and adjusted accordingly. The effective amount can remain constant or can be increased or decreased proportionally or adjusted in variable dosages depending on the mammal's response to the treatment. Various factors can affect the actual effective amount for a specific application. For example, the frequency of administration, duration of treatment, use of multiple therapeutic agents, route of administration, and severity of the lymphoma may require an increase or decrease in the effective amount actually administered.
[0035] The frequency of administration can be any frequency that reduces the rate of lymphoma progression, increases the rate of progression-free survival, or increases the median time to progression without causing significant toxicity to the mammal. For example, the frequency of administration can be from about once a month to about three times a month, or from about twice a month to about six times a month, or from about once every two months to about three times every two months. The frequency of administration can remain constant or can be variable during the duration of treatment. The course of treatment with a composition containing / anti-CD20 polypeptide antibody complex can include rest periods. For example, a composition containing / anti-CD20 polypeptide antibody complex can be administered over a two-week period, followed by a two-week rest period, and this regimen can be repeated multiple times. As with the effective amount, various factors can affect the actual frequency of administration for a specific application. For example, the effective amount, duration of treatment, use of multiple therapeutic agents, route of administration, and severity of the lymphoma may require an increase or decrease in the frequency of administration.
[0036] The effective duration for administering the compositions provided herein can be any duration that reduces the rate of lymphoma progression, increases the progression-free survival rate, or increases the median time to progression without causing significant toxicity to the mammal. Thus, the effective duration can vary from a few days to weeks, months, or years. Generally, the effective duration for treating lymphoma can be in the range of a few weeks to a few months. In some cases, the effective duration can be as long as the survival of the individual mammal. Multiple factors can affect the actual effective duration for a specific treatment. For example, the effective duration can vary with the frequency of administration, effective amount, use of multiple therapeutic agents, route of administration, and severity of the lymphoma.
[0037] Compositions comprising the albumin-containing nanoparticle / antibody complexes provided herein (e.g., / anti-CD20 polypeptide antibody complexes) can be in any suitable form. For example, the compositions provided herein can be in the form of a solution or powder, with or without a diluent, to prepare an injectable suspension. The composition can also contain other ingredients, including but not limited to pharmaceutically acceptable carriers. Pharmaceutically acceptable carriers can be, for example, saline, water, lactic acid, mannitol, or combinations thereof.
[0038] After administering the compositions provided herein to a mammal, the mammal can be monitored to determine if the lymphoma has been treated. For example, the mammal can be evaluated after treatment to determine if the rate of progression of the lymphoma has decreased (e.g., stopped). As described herein, any method can be used to evaluate progression and survival.
[0039] In some cases, as in the method set forth in Example 3, the formulation of the / Rituxan complex described in Example 1 can be administered to human lymphoma patients.
[0040] In some cases, albumin-containing nanoparticles (e.g., nanoparticles with an albumin shell) and a reagent other than paclitaxel can be used to replace or in combination with as described herein. For example, albumin-containing nanoparticles designed to carry a cancer chemotherapeutic agent can be used to form nanoparticle / anti-CD20 polypeptide antibody complexes that can be used as described herein. Examples of such cancer chemotherapeutic agents include but are not limited to vinblastine.
[0041] In some cases, the composition can be formulated to include albumin-containing nanoparticles (e.g., nanoparticles with an albumin shell) that bind to an antibody, a reagent, or a combination of an antibody and a reagent to form a complex for treating lymphoma. For example, albumin nanoparticles can be formulated to include doxorubicin, cyclophosphamide, vincristine, prednisone, dexamethasone, cytarabine, methotrexate, thiotepa, ifosfamide, chlorambucil, dacarbazine, bleomycin, alemtuzumab-B, gemcitabine, lenalidomide, sirolimus, temsirolimus, bexarotene, ceritinib, bendamustine, etoposide, or combinations thereof, with or without rituximab.
[0042] In certain cases, albumin-containing nanoparticles (e.g., nanoparticles with an albumin shell) or the complexes described herein (e.g., / rituximab complex) with one or more anti - chronic inflammation therapeutic agents designed to reduce the global state of immune dysfunction and / or chronic inflammation present in cancer patients. For example, steroidal anti - inflammatory agents (e.g., prednisone), non - steroidal anti - inflammatory agents (e.g., naproxen), lymphodepleting cytotoxic agents (e.g., cyclophosphamide), immune cell - and / or cytokine - targeting antibodies (e.g., infliximab) or combinations thereof can be incorporated into the albumin - containing nanoparticles or / rituximab complex. In some cases, anti - IL - 4 agents (e.g., anti - IL - 4 antibodies), anti - IL - 13 agents (e.g., soluble IL - 13 receptor) and combinations thereof can be incorporated into the albumin - containing nanoparticles or / rituximab complex.
[0043] Any suitable method can be used to evaluate whether the global state of immune dysfunction and / or chronic inflammation is reduced after anti - chronic inflammation treatment. For example, the cytokine profile present in the blood (e.g., IL - 4, IL - 13, IL - 4, IL - 13, IL - 5, IL - 10, IL - 2 and interferon - γ) can be evaluated before or after anti - chronic inflammation treatment to determine whether the global state of immune dysfunction and / or chronic inflammation is reduced.

Ten milligrams of will be reduced in 1 mL of at 0, 2, 4, 6, 8, and 10 mg / mL, and the mixture will be incubated at room temperature for 30 minutes. After incubation, the particle size distribution will be determined using a Mastersizer 2000. For 0 and 10 mg / mL of , the median particle sizes are in the ranges of 0.147 μm to 8.286 μm ( ). These results demonstrate that the antibody concentration at which Figure 1 is incubated affects the size of the nanoparticles. Manipulating the size of the particles can alter the pharmacokinetics and biodistribution of the drug complex, which in turn can improve the clinical efficacy of the drug complex. will
[0121] Example 2 - / Rituxan complex is more effective than alone Rituxan and Rituxan in combination with sequential use in inhibiting tumor growth
[0122] Female athymic nude mice will be injected with 1 × 10 6 lymphoma cells (Daudi cell line). The tumors will be allowed to grow, and treatment will be administered when the tumors are between 800 and 1000 mm 3 . Treatment will be with (a) a single dose of 100 μL of PBS on day 0, (b) a single dose of Rituxan (12 mg / kg) on day 0, (c) a single dose of (30 mg / kg) on day 0, (d) a single dose of Rituxan (12 mg / kg) on day 0 followed by a single dose of (30 mg / kg) on day 1, or (e) a single dose of AR160 (equivalent to 30 mg / kg of )Treat mice. Monitor tumor volume (mm 3 ), and determine the percentage change in tumor volume seven days after treatment.
[0123] The AR160 complex was prepared as follows. 10 mg was reduced to 2 mg of Rituxan in 500 μL of 0.9% saline and incubated at room temperature for 1 hour. After incubation, AR160 was adjusted to 1 mL with 0.9% saline. AR160 was further diluted and 100 μL was administered to mice at a dose equivalent to 12 mg / kg Rituxan and 30 mg / kg . The average particle size of AR160 was 0.159 μm.
[0124] On day 7 after treatment, mice treated with AR160 showed tumors with significantly smaller tumor sizes compared to other treatment groups ( Figure 2 ). Survival data also revealed an improvement in mice treated with / Rituxan complex ( Figure 3 ). These results demonstrate that the albumin nanoparticle / antibody complexes provided herein (e.g., / anti-CD20 polypeptide antibody complex) can be effectively used for the treatment of lymphoma.
[0125] Example 3 - / Rituxan complex as a targeted therapy for lymphoma
[0126] Repeat the / Rituxan complex treatment plan monthly (every 28 days + / - 3 days) or until disease progression, patient refusal, or unacceptable toxicity (Table 1) and dose-limiting toxicity (Table 3) with the specified dose escalation protocol (Table 2).

[0133] Table 3. Dose-limiting toxicity (DLT).
[0134]
[0135] Determination of the maximum tolerated dose (MTD)
[0136] The maximum tolerated dose is defined as the highest dose level among those tested where at most one out of six patients shows a DLT before the start of their second cycle of treatment, and the next highest dose level is such that at most two out of six patients treated at this dose level show a DLT before the start of their second treatment cycle.
[0137] Enrollment and determination of the MTD
[0138] Accumulate a given dose level in at least two or at most six patients. For dose level 1 (and if cumulative, dose levels -1 and -2), temporarily stop enrollment after each patient is enrolled in order to collect acute adverse event data during their first cycle of treatment. For dose levels 2 and 3, accumulate patients to these dose levels such that at no given time are more than two patients receiving their first cycle of treatment and acute adverse event data is known for all other patients being treated at the current dose level during the first treatment cycle. If at any time during the enrollment process, two patients being treated at the current dose level show a DLT during the first cycle of treatment, close enrollment for that dose level. If fewer than six patients are being treated at that dose level, reopen enrollment at the next lower dose level. If none of the first three patients being treated at a given dose level show a DLT during the first cycle of treatment, close enrollment for that dose level and reopen enrollment at the next higher dose level. If there are no other higher dose levels to test, enroll three additional patients at the current dose level to confirm the MTD. If one of the first three patients being treated at a given dose level shows a DLT during the first cycle of treatment, enroll three additional patients (sequentially) at the current dose level. If at any time during the enrollment of these three additional patients, a patient shows a DLT, close enrollment for that dose level. If fewer than six patients are being treated at that dose level, reopen enrollment at the next lower dose level. If none of these three additional patients show a DLT during the first cycle of treatment, close enrollment for that dose level and reopen enrollment at the next higher dose level. If there are no other higher dose levels to test, consider it the MTD.
[0139] For the protocol, patients return according to schedule for evaluation and retreatment (at least every 28 + / - 3 days). If a patient cannot complete the first cycle of treatment for reasons other than toxicity, enroll another patient to replace that patient.
[0140] Dose modification based on adverse events
[0141] Follow the modifications in Table 4 until the treatment tolerance of the monomer is determined. If multiple adverse events are observed (Table 5), the dose is given based on the maximum reduction required for any single adverse event observed. Dose modifications apply to the treatment given in the previous cycle and are based on the adverse events observed since the previous dose.
