FIELD OF THE INVENTION

The present application relates to dosage and administration of anti-DLL3 agents for the treatment of cancer.

BACKGROUND OF THE INVENTION

Small cell lung cancer (SCLC) is an aggressive form of lung cancer with a poor prognosis and limited therapeutic options and represents about 10-15% of lung cancers. Survival rates have remained low for several decades, with only 5% of SCLC patients surviving five years, in a large part due to the lack of new therapies to combat this form of lung cancer. About a third of patients present with limited stage disease. Most patients present with extensive-stage disease, defined by the presence of tumors in only one side of the chest and that fit in a single radiation field. These stages impact available therapeutic regiments, with limited stage disease treated with chemotherapy and radiation and extensive stage disease treated with chemotherapy alone. Disseminated, metastatic tumors with lymphoma-like characteristics are a hallmark of SCLC.

Patients typically respond well to the current front-line therapy, which includes etoposide and cisplatin, but invariably quickly relapse with chemoresistant disease, for which no therapeutic options are currently available. Prognosis in the relapsed refractory setting is extremely poor, with rapid disease progression and short median survival of less than six months. Furthermore, SCLC patients have high rates of comorbidities, including hypertension, cardiac disease, diabetes and paraneoplastic syndromes. These, coupled with the typically advanced age of SCLC patients, impact the ability of patients to endure harsh chemo regimens, further limiting treatment options.

Delta-like 3 (DLL3) is a type 1 transmembrane protein and noncanonical Notch ligand that is differentially expressed in SCLC. Using immunohistochemistry (IHC), 85% of SCLC tumors stained positive for DLL3 in a pattern consistent with both membranous and cytoplasmic expression. In contrast, low levels of DLL3 protein expression were detected in normal brain, pancreatic islets, and pituitary gland with a cytoplasmic staining pattern (Saunders et al, Sci Transl Med. 7:302ra136 (2015)). DLL3 is a novel and promising target for the development of T-cell-targeted therapies for SCLC.

There is an unmet medical need for the development of therapies for the treatment of SCLC.

DETAILED DESCRIPTION

As disclosed and exemplified herein, a Phase 1 clinical study was conducted for the treatment of SCLC, using a bispecific protein (AMG 757) that targets DLL3 and CD3.

AMG 757 is a half-life-extended BiTE® (bispecific T cell engager) molecule developed for the treatment of SCLC. The activity of AMG 757 requires the simultaneous binding to both target cells (DLL3⁺ cells) and T cells. The pharmacological effect of AMG 757 is mediated by specific redirection of previously primed cytotoxic CD8⁺or CD4⁺ T lymphocytes to kill DLL3⁺ cells. The selection of the starting dose for the First in Human (FIH) study was based on the Minimum Anticipated Biological Effect Level (MABEL), which was identified as the EC₅₀ of AMG 757-mediated CD69 upregulation in SHP-77 cells (Study 123564). A starting dose of 0.003 mg once every two weeks (Q2W) was selected based on human PK predictions and is predicted to generate maximum serum concentrations equivalent to the MABEL (0.61 ng/mL). This regimen is expected to achieve adequate exposures in target tissues (e.g., lung) throughout the entire dosing interval, while minimizing peak-to-trough ratios after multiple treatment cycles of AMG 757. Based on clinical experience in the FIH study, a dose of at least 0.3 mg Q2W is desirable.

1. Definition

Some of exemplary bispecific anti-DLL3 agents disclosed herein (such as BiTE® molecules) are recombinant protein constructs comprising two binding domains, each domain derived from an antigen-binding fragment of a full-length antibody. Such antigen-binding fragment retains the ability to specifically bind to an antigen (preferably with substantially the same binding affinity). Examples of an antigen-binding fragment includes (i) a Fab fragment, a monovalent fragment consisting of the VL, VH, CL and CH 1 domains; (ii) a F(ab′)₂ fragment, a bivalent fragment comprising two Fab fragments linked by a disulfide bridge at the hinge region; (iii) a Fd fragment consisting of the VH and CH1 domains; (iv) a Fv fragment consisting of the VL and VH domains of a single arm of an antibody, and (v) a dAb fragment (Ward et al.. 1989 Nature 341:544-546), which consists of a VH domain. Furthermore, although the two domains of the Fv fragment, VL and VH, are coded for by separate genes, they can be joined, using recombinant methods, by a synthetic linker that enables them to be made as a single protein chain in which the VL and VH regions pair to form monovalent molecules (known as single chain Fv (scFv); see e.g., Bird et al. Science 242:423- 426 (1988) and Huston et al., 1988, Proc. Natl. Acad. Sci. USA 85:5879-5883.

A “variable domain” refers to the variable region of the antibody light chain (VL) or the variable region of the antibody heavy chain (VH), either alone or in combination. As known in the art, the variable regions of the heavy and light chains each consist of four framework regions (FR) connected by three complementarity determining regions (CDRs), and contribute to the formation of the antigen-binding site of antibodies.

The “Complementarity Determining Regions” (CDRs) of exemplary DLL3-binding domains and CD3-binding domains are provided in the Sequence Table. The CDRs can be defined according to Kabat, Chothia, the accumulation of both Kabat and Chothia, AbM, contact. North, and/or conformational definitions or any method of CDR determination well known in the art. See, e.g., Kabat et al., 1991, Sequences of Proteins of Immunological Interest, 5th ed. (hypervariable regions); Chothia et al., 1989, Nature 342:877-883 (structural loop structures). AbM definition of CDRs is a compromise between Kabat and Chothia and uses Oxford Molecular’s AbM antibody modeling software (Acceltys®). The identity of the amino acid residues in a particular antibody that make up a CDR can be determined using methods well known in the art.

The term “treatment” includes prophylactic and/or therapeutic treatments. If it is administered prior to clinical manifestation of a condition, the treatment is considered prophylactic. Therapeutic treatment includes, e.g., ameliorating or reducing the severity of a disease, or shortening the length of the disease.

“About” or “approximately,” when used in connection with a measurable numerical variable, refers to the indicated value of the variable and to all values of the variable that are within the experimental error of the indicated value (e.g. within the 95% confidence interval for the mean) or ±10% of the indicated value, whichever is greater. Numeric ranges are inclusive of the numbers defining the range.

“Run-in dose” when used in connection with administration of anti-DLL3 agents for the treatment of cancer (e.g.. small cell lung cancer (SCLC)) refers to the initial dose of an anti-DLL3 agent equal to or lower than a dose at which a first dose effect (e.g.. cytokine release syndrome (CRS)) is observed. As known in the art, run-in dose can be determined by modeling and simulation of safety and pharmacokinetic data. For example, run-in dose can be a maximum tolerated dose (MTD) of an anti-DLL3 agent where no CRS or a CRS lower than a certain grade (e.g., Grade 2) is observed.

“Target dose” when used in connection with administration of anti-DLL3 agents for the treatment of cancer (e.g., SCLC) refers to a dose that achieves a target effect of an anti-DLL3 agent (e.g., ameliorating or reducing the severity of SCLC, or shortening the length of the SCLC).

“Step dose” when used in connection with administration of anti-DLL3 agents for the treatment of cancer (e.g.. SCLC) refers to a dose that is higher than the previous dose at which an anti-DLL3 agent is administered. Step dose includes one or more doses that increase from a run-in dose to reach a target dose.

2. Anti-DLL3 Agents

DLL3 is a non-canonical Notch ligand expressed primarily during embryonic development that functions during somitogenesis. In contrast to other Notch ligands that are expressed on the surface of cells, DLL3 accumulate in the Golgi in normal tissues (Geffers et al, J Cell Biol.178:465-476 (2007)). DLL3 was identified as a tumor-associated antigen and a compelling target for T cell-based therapies by analyzing the differential expression of this target in 28 SCLC tumors and a large panel of normal tissues (Study 123658).

The human DLL3 protein comprises eight extracellular domains: signal peptide, N-terminus, DSL, EGF1, EGF2, EGF3, EGF4, EGF5 and EGF6. The amino acid sequence of human DLL3, the EGF3 domain, the EGF4 domain, and the combined EGF3 and EGF4 domains are shown in the sequence table as SEQ ID NOs: 252, 258, 259 and 260, respectively.

An exemplary anti-DLL3 agent is a bispecific molecule that binds DLL3 and CD3, such as a BiTE® (bispecific T cell engager) molecule. BiTE® molecules are recombinant protein constructs made from two flexibly linked binding domains, each domain derived from antibodies. One binding domain of BiTE® molecule is specific for a tumor-associated surface antigen (such as DLL3); the second binding domain is specific for CD3, a subunit of the T cell receptor complex on T cells. By their design, BiTE® molecules are uniquely suited to transiently connect T cells with target cells and, at the same time, potently activate the inherent cytolytic potential of T cells against target cells. See e.g., WO 99/54440, WO 2005/040220, and WO 2008/119567.

In certain embodiments, the anti-DLL3 agent is administered once every two weeks at a dose of: from about 3 mg to about 100 mg, from about 10 mg to about 200 mg, from about 10 mg to about 180 mg, from about 10 mg to about 150 mg, from about 10 mg to about 120 mg, from about 30 mg to about 200 mg, from about 30 mg to about 180 mg, from about 30 mg to about 150 mg, from about 30 mg to about 120 mg, from about 50 mg to about 200 mg, from about 50 mg to about 180 mg, from about 50 mg to about 150 mg, from about 50 mg to about 120 mg, from about 70 mg to about 200 mg, from about 70 mg to about 180 mg, from about 70 mg to about 150 mg, from about 70 mg to about 120 mg, from about 90 mg to about 200 mg, from about 90 mg to about 180 mg, from about 90 mg to about 150 mg, from about 90 mg to about 120 mg, from about 100 mg to about 180 mg, from about 100 mg to about 150 mg, or from about 100 mg to about 120 mg.

In certain embodiments, the anti-DLL3 agent is administered once every two weeks at a dose of about 3 mg, 10 mg, 30 mg, or 100 mg.

In certain embodiments, the anti-DLL3 agent is administered on day 1 and day 15 of a 28-day cycle.

As described Example 2, the starting dose for the FIH study was based on the Minimum Anticipated Biological Effect Level (MABEL), which was identified as the EC50 of AMG 757-mediated CD69 upregulation in SHP-77 cells (Study 123564). A starting dose of 0.003 mg was selected based on human PK predictions and is predicted to generate maximum serum concentrations equivalent to the MABEL (0.61 ng/mL). The dose of AMG 757 in the Phase 1 clinical study is 0.003 mg and higher and is administered as intravenous (IV) infusions once every two weeks (Q2W) in patients with SCLC. This regimen is believed to achieve adequate exposures in target tissues (e.g., lung) throughout the entire dosing interval, while minimizing peak-to-trough ratios after multiple treatment cycles of AMG 757.

Predicted human PK parameters were used to predict AMG 757 concentrations in the lung, which was designated as the representative site of action and was assumed to achieve approximately 1% of serum exposures (Vugmeyster et al, 2010). Early signs of efficacy were predicted at 10 mg every 2 weeks based on trough coverage of the average EC₉₀ of cell killing in SHP-77 cells (assuming 1% lung exposure), see e.g., Example 2.

There was one confirmed response at 0.3 mg administered as IV infusion once every two weeks (Cohort 5) in the clinical study. This observed efficacy of AMG 757 is surprising because it is significantly lower than the dose of 10 mg Q2W that was predicted to be efficacious based on pre-clinical results. Additional confirmed responses were observed in higher dose cohorts. It is believed that efficacious dose of AMG 757 can be at least 0.3 mg (e.g., from about 0.3 mg to about 100 mg or from about 3 mg to about 200 mg) administered once every two weeks.

The anti-DLL3 agent can be administered by any suitable means, including parenteral, subcutaneous, intraperitoneal, intrapulmonary, intranasal, and/or intralesional administration. Parenteral administration includes intramuscular, intravenous, intraarterial, intraperitoneal, or subcutaneous administration. In some embodiments, the anti-DLL3 agent is administered by intravenous (IV) infusion, such as a short IV infusion (approximately 60 minutes), once every two weeks.

3.1 Step Dosing

Due to its mechanism of action, subjects may be at an increased risk for first dose effects (e.g., cytokine release syndrome) following initial infusion of AMG 757. It is believed that an optimal maximal tolerated dose (MTD) may require a step dosing approach (e.g., initial dose on day 1, step dose on Day 8, and subsequent dose starting on day 15 and thereafter). In certain aspects, two MTDs may be estimated or established, one for the initial dosing (MTD1, run-in dose) and one for the subsequent dosing (MTD2). In certain aspects, multiple MTDs may be estimated or established, one for the initial run-in dose (MTD1) and one for each step dose(s) and the subsequent dose, as applicable.

If a first dose effect (e.g., cytokine release syndrome (CRS)) is experienced by a subject, an appropriate first dose (MTD1) not exceeding the dose at which a CRS event is observed can be determined and implemented. A second dose and a subsequent dose can also be determined and implemented. In addition, a second dose, a third dose, a fourth dose and a subsequent dose can be determined and implemented, depending on the number of steps in a step dosing schedule. In certain embodiments, the second dose and the subsequent dose are the same, and are higher than the first dose. In certain embodiments, the second dose is higher than the first dose, and the third and subsequent doses are the same, and are higher than the second dose. In certain embodiments, the second dose is higher than the first dose, the third dose is higher than the second dose, and the fourth and subsequent doses are the same, and are higher than the third dose. These doses and dosing schedules can be guided by modeling and simulation of clinical data (e.g., pharmacokinetics, safety data, etc.) to ensure that systemic exposures of AMG 757 may not exceed those associated with doses at which first dose effects were seen (e.g., CRS) due to the increased dosing frequency of a step dosing regimen and potential for drug accumulation.

Exemplary step dosing schedules of anti-DLL3 agents (e.g., AMG 757) in a 28-day cycle are shown in the table below (cycle 1 only), the anti-DLL3 agent is administered once every two weeks thereafter.

3.2 Co-Administration

In some embodiments, the compositions and methods of the invention provide for the use of an anti-DLL3 agent in combination with one or more additional therapeutic agents. In certain embodiments, the one or more additional therapeutic agents is an agent that mitigates CRS of anti-DLL3 agents (e.g., AMG 757). In certain embodiments, the one or more additional therapeutic agents include an anti-inflammatory agent, a fluid (e.g., saline), an anti-IL6 antibody (e.g., tocilizumab) or an anti-TNF agent (e.g., etanercept). In certain embodiments, the methods disclosed herein comprise the administration of an anti-DLL3 agent (e.g., AMG 757) in combination with one or more of an anti-inflammatory agent, a fluid (e.g., saline), an anti-IL6 antibody (e.g., tocilizumab) and an anti-TNF agent (e.g., etanercept).

In some embodiments, the one or more additional therapeutic agents may be an anti-inflammatory agent (for example, to prophylactically treat CRS). The anti-inflammatory agent may be administered prior to, concurrently, or after the administration of the anti-DLL3 agent. Exemplary anti-inflammatory agent includes acetaminophen, naproxen sodium, ibuprofen, tramadol, aspirin, celecoxib, valdecoxib, indomethacin, or other Non-steroidal anti-inflammatory drugs (NSAIDs). Other anti-inflammatory agent includes, e.g., beclomethasone, hydroxycortisone, betamethasone, methylprednisolone, budesonide, prednisolone, cortisone, prednisone, dexamethasone, and triamcinolone, or other glucocorticoids. In certain embodiments, the anti-inflammatory agent is a corticosteroid. In certain embodiments, the corticosteroid is dexamethasone. In certain embodiments, the anti-inflammatory agent is acetaminophen. In certain embodiments, the anti-inflammatory agent (e.g., a corticosteroid such as dexamethasone or acetaminophen) is administered before the administration of the anti-DLL3 agent. In certain embodiments, dexamethasone is administered intravenously, e.g., prior to cycle 1 doses of AMG 757. In certain embodiments, dexamethasone is administered orally.

In some embodiments, the one or more additional therapeutic agents that mitigate CRS are a fluid (e.g., saline), an anti-IL6 antibody (e.g., tocilizumab) or an anti-TNF agent (e.g., etanercept). Each of these agents may be administered prior to, concurrently, or after the administration of the anti-DLL3 agent. In certain embodiments, saline is administered (e.g., by IV administration) after the administration of the anti-DLL3 agent. In certain embodiments, the anti-IL6 antibody (e.g., tocilizumab) or the anti-TNF agent (e.g., etanercept) is administered prior to the administration of the anti-DLL3 agent.

EXAMPLES
Example 1 Prediction of Human AMG 757 Pharmacokinetics and First-inHuman Dose Selection

The human PK parameters of AMG 757 were predicted using allometric scaling of PK parameters obtained from studies in cynomolgus monkeys at doses ranging from 12 to 4500 µg/kg. A two-compartment model with linear elimination was used to characterize the pharmacokinetics of AMG 757 from the pooled cynomolgus monkey data, excluding data from animals that were identified as positive for anti-drug antibodies after the administration of the first dose. The model was parameterized using linear clearance (CL), volume of distribution of central compartment (Vc), distribution clearance (CL_D), and peripheral volume of distribution (V_T). Allometry was used to predict human AMG 757 PK using exponents of 0.75 and 1 for clearance and volume parameters, respectively. The human and cynomolgus monkey body weights were assumed to be 60 kg and 3 kg, respectively. Derived monkey and predicted human AMG 757 PK parameters are provided in Table 1.

In combination with these PK predictions, the FIH starting dose was selected based on the identified in vitro Minimum Anticipated Biological Effect Level (MABEL). This concentration was determined by assessing the most sensitive marker of AMG 757 activity in the most sensitive DLL3-expressing cell line (Study 123564). In conjunction with animal exposures from the GLP toxicology studies, the predicted human exposures were used to calculate the exposure margins using standard ratio calculations based on AUC_tau (168 hours for cynomolgus monkeys in the GLP toxicology study and 336 hours for humans) and C_max for the proposed doses in the FIH study.

The FIH study evaluates the safety, tolerability, and pharmacokinetics of AMG 757 in patients with small cell lung cancer. The predicted human PK parameters described above were used to simulate predicted exposures at the proposed FIH doses (FIG. 1). The doses of AMG 757 for the FIH study are 0.003 mg, 0.01 mg, 0.03 mg, 0.1 mg, 0.3 mg, 1 mg, 3 mg, 10 mg, 30 mg, 100 mg, and higher administered as short-term IV infusions (approximately 1 hour) once every two weeks in patients with small cell lung cancer (SCLC) (Study 20160323). This regimen ensures that adequate exposures over the in vitro EC₉₀ for AMG 757-mediated cell killing (5.2 ng/mL) are achieved in lung while minimizing peak-to-trough ratios during multiple treatment cycles of AMG 757.

The selection of the starting dose for the FIH study was based on the in vitro MABEL. Briefly, the EC₅₀ values of AMG 757-mediated cell killing of SHP-77 tumor cells and induction of T cell activation (de novo expression of CD69 and CD25) from human peripheral blood mononuclear cells (PBMCs) were compared, and AMG 757-induced de novo expression of CD69 on T cells was identified as the most sensitive parameter of AMG 757 activity. Based on the assessment of individual dose-response curves from 12 different PBMC donors, the MABEL (mean EC₅₀) was calculated to be 0.61 ng/mL (5.8 pM; Study 123564).

The use of the in vitro EC₅₀ as the MABEL and basis for the FIH starting dose is supported by the previous and safe implementation of this strategy to identify the maximum recommended starting doses of previous BiTE® molecules in clinical development.

Example 2 Prediction of Minumumly Effecious Exposures of AMG 757 in Humans

Efficacious exposures of AMG 757 were predicted based on in vitro data generated in Study 122717, which evaluated the in vitro pharmacology of AMG 757. Concentrations for half-maximal effect (EC₅₀) and 90% of maximal effect (EC₉₀) of AMG 757-mediated cell killing in SHP-77 cells (human DLL3-expressing cell line) were used to estimate a concentration range in which efficacy may be expected.

The lungs were used as the representative site of action for AMG 757 and were assumed to achieve exposures of approximately 1% of free serum exposures (Vugmeyser et al., J Pharm Sci. 99:1028-1045 (2010)). Based on this assumption, doses of AMG 757 to provide trough coverage of the EC₅₀ of AMG 757-mediated cell killing in SHP-77 cells were considered to be minimally efficacious. Early signs of efficacy were predicted at 10 mg IV once every two weeks based on trough coverage of the average EC₉₀ of cell killing in SHP-77 cells (assuming 1 % lung exposure) for the entire treatment cycle (FIG. 2).

Example 3 Phase 1 Study Evaluating the Safety, Tolerability And Pharmacokinetics of AMG 757 IN Subjects With SCLC
Background

Small Cell Lung Cancer (SCLC), accounting for 10-15% of lung cancer (Rudin et al, J Clin Oncol. 33:4106-4111(2015)), is an aggressive lung cancer subtype with neuroendocrine differentiation and strongly associated with smoking (Koinis et al, Transl Lung Cancer Res. 5:39-50 (2016)). It displays a distinct natural history characterized by a high growth fraction, rapid doubling time and early establishment of widespread metastatic lesions (Gustafsson et al, Cancer.113:5-21(2008)). While 30% of patients present with disease confined to one hemithorax [limited disease (LD)], the majority of cases have disease not encompassed by one radiotherapy field [extended disease (ED)]. SCLC is exquisitely sensitive to first-line chemotherapy (approximately 60%-70% response rates) and to radiation which is stark contrast to subsequent resistance to second-line and subsequent therapies after disease recurrence (Byers et al, Cancer.121:664 672(2015)). Patients with ED develop drug resistance and die as a result of disease at a median time of 10 to 12 months from diagnosis (Rudin et al, 2015). For patients with ED SCLC, first line treatment is platinum-based chemotherapy. Most patients in the United States receive platinum-etoposide (EP) chemotherapy (with either carboplatin or cisplatin), and some patients receive platinum-irinotecan as an alternative, especially outside the United States. In March 2019, atezolizumab was approved by the United States Food and Drug Administration (US FDA) in combination with carboplatin and etoposide for the first-line treatment of adult patients with ED-SCLC (Tecentriq® United States Prescribing Information [USPI], 2019). After relapse, topotecan is the only second-line drug approved by the US FDA. However, despite its indication in this setting, topotecan has produced disappointing response rates (Byers et al, Cancer.121:664 672(2015)).

AMG 757 is a half-life extended (HLE) BiTE® molecule targeting DLL3 as a tumor-specific antigen and T-cell receptor-associated complex cluster of differentiation 3 (CD3) on T-cells. AMG 757 is developed for the treatment of SCLC and is a potent molecule acting by formation of an immunological synapse between CD3-positive T cells and cancer cells expressing the DLL3 protein. The resulting proximity triggers the redirected lysis of DLL3-positive target cells by the T cells. AMG 757 monotherapy significantly inhibited growth of subcutaneously implanted DLL3 expressing human melanoma WM266-4 cells and induced regression of orthotopic SHP-77-Luc lung tumors.

Study Design

Study 20160323 is an open-label, ascending, multiple dose, phase 1 study evaluating AMG 757 administered as a short term intravenous (IV) infusion every 2 weeks (with or without Day 8 step dosing for example) in subjects with small cell lung cancer. There are two indications for this Study: A: Relapsed/refractory small cell lung cancer (RR SCLC) and B: Extensive disease SCLC (ED SCLC).

Due to its known mechanism of action, subjects are at an increased risk of CRS during initiation of AMG 757 treatment.

The study contains three parts:

(1) Part A: Evaluate AMG 757 in subjects with relapsed/refractory small cell lung cancer (RR SCLC). Part A contains two phases: (A1) Dose Exploration phase to determine maximum tolerated dose (MTD) or recommended phase 2 dose (RP2D) of AMG 757, and (A2) Dose Expansion phase to confirm the safety and tolerability of the selected dose.
(2) Part B: Evaluate AMG 757 in subjects with Extensive disease SCLC (ED SCLC). Part B commences once MTD or RP2D is identified in Part A.
(3) Part C (evaluation of additional CRS mitigation strategies): AMG 757 monotherapy for subjects with RR SCLC who progressed after at least 1 platinum-based regimen. To mitigate the risk of CRS, one or more of the following prophylactic measures may be implemented (during cycle 1 only): IV hydration, additional corticosteroid prophylaxis with oral dexamethasone administration of tocilizumab prophylaxis, etanercept prophylaxis, or acetaminophen prophylaxis.

The primary objectives for both Part A and Part B of the study are to evaluate the safety and tolerability of AMG 757 and to determine MTD or RP2D of AMG 757. The secondary objectives of both Part A and Part B of the study are to characterize the pharmacokinetics (PK) of AMG 757 and to evaluate preliminary anti-tumor activity of AMG 757.

Part A1: Dose Exploration Phase

AMG 757 is administered as a short IV infusion (approximately 60 minutes). Pre-specified doses for use in the dose escalation (planned dose levels for investigation) are: 0.003 mg (Cohort 1), 0.01 mg (Cohort 2), 0.03 mg (Cohort 3), 0.1 mg (Cohort 4), 0.3 mg (Cohort 5), 1 mg (Cohort 6), 3 mg (Cohort 7), 10 mg (Cohort 8), 30 mg (Cohort 9), and 100 mg (Cohort 10), administered once every two weeks. Dosing schedule in first cycle may be adjusted to include one or more step doses as described below. If compelling clinical responses are observed during the escalation period, further dose escalation can be stopped. Alternative dose levels or dosing schedule(s) of AMG 757 may be explored based on emerging pharmacokinetic (PK), pharmacodynamic (PD) and safety data. Higher doses may be explored if MTD is not reached at planned dose cohort levels (Cohorts 1-10) and supported by safety and PK/PD data.

Step Dosing: subjects may experience first dose effects (e.g., cytokine release syndrome with associated manifestations and any other potentially evolving and unknown first dose effects) following the initial infusion of AMG 757. It is believed that an optimal MTD may require a step dosing approach (e.g., initial dose on day 1 and step dose on Day 8). Two MTDs may be estimated, one for the initial dosing (MTD1) and one for the subsequent dosing (MTD2).

At any point during the study, the first time a subject experiences a first dose effect (e.g., CRS event of any grade), the safety data need to be reviewed to determine the appropriate dose to be implemented as an initial dose (MTD1), which does not exceed the dose where a CRS of Grade 2 or higher is observed. These doses and dosing schedules are guided by modeling and simulation of emerging clinical data (e.g., pharmacokinetics, safety data, etc.) to ensure that systemic exposures of AMG 757 do not exceed those associated with doses at which first dose effects were seen. Increased dosing frequency of a step dosing regimen and potential for drug accumulation need to be taken into account.

For all subjects enrolled in subsequent cohorts throughout the study, dose escalation continues with a constant dose for the first dose of the first cycle of AMG 757 (MTD1) and only the step dose will be escalated according to the pre-specified doses in the dose escalation to determine MTD2. An example of step dosing is shown in FIG. 3.

Step dosing schedules are summarized below. The dosing schedule may be adapted to include one or more of the following measures, as per DLRT recommendation based on emerging safety data.

Single-step dosing involving a run-in dose on day 1, followed by a step dose on day 8 (equal to the target dose) and the target dose on day 15 and then Q2W.
Two-step dosing (option 1) involving a run-in dose on day 1, followed by a step dose on day 4, a step dose on day 8 (equal to target dose) and the target dose on day 15 then Q2W.
Two-step dosing (option 2) involving a run-in dose on day 1, followed by a step dose on day 8, a step dose on day 15 (equal to the target dose) and the target dose on cycle 2 day 1 then Q2W.
Three-step dosing involving a run-in dose on day 1, followed by a step dose on day 4, a step dose on day 8, a step dose on day 15 (equal to the target dose) and the target dose on cycle 2 day 1 then Q2W.

Part A2: Dose expansion phase. Part A2 commences once the MTD or RP2D is selected based on dose exploration phase (Part A1).

Part B: Part B will commence once a preliminary MTD or RP2D in Indication A (Part A1) is established.

Part C: One or more additional CRS mitigation strategies as outlined below may be evaluated, as per DLRT recommendation based on emerging safety data. Part C will commence while Part A1 is ongoing.

Prophylaxis with IV hydration 1 L normal saline over 4-5 hours immediately following the run-in dose and step dose(s) in cycle 1
Additional corticosteroid prophylaxis with dexamethasone 8 mg PO 6-16 hour prior to the run-in dose and step dose(s) in cycle 1
Tocilizumab 8 mg/kg IV 1 hour prior to the run-in dose and step dose(s) in cycle 1
Etanercept 50 mg SQ on day -2 and then 2 days prior to the run-in dose and step dose(s) in cycle 1 (with the exception of the step dose on Day 4 with two-step or three-step dosing)
Acetaminophen 650 mg po 1 hour prior to the run-in dose and step dose(s) in cycle 1

The above CRS mitigation strategies will initially be administered with IV dexamethasone. Based on the emerging safety profile, IV dexamethasone may be discontinued while continuing with one of the above CRS strategies alone to assess the safety profile without steroid premedication.

Each subject enrolled in Part C will receive only one of the above additional CRS mitigation strategies in addition to their AMG 757 therapy as described above. Subjects will start with a dose of AMG 757 that has been deemed safe and tolerable. If based on emerging safety data the incidence of CRS is reduced, then one or more of the above strategies may be implemented into Parts A or B.

Secondary Endpoints: For Indications A and B: (1) PK parameters for AMG 757 following intravenous administration including but not limited to maximum observed concentration (C_max), minimum observed concentration (C_min), area under the concentration-time curve (AUC) over the 2 week dosing interval, accumulation following multiple dosing, and, if feasible, half-life (t½), (2) Objective Response (OR) per modified Response Evaluation Criteria in Solid Tumors (RECIST) 1.1, (3) Duration of Response (DOR), and (4) 1-year Progression-Free Survival (PFS), and (5)1-year Overall Survival (OS). For Indication B only: Relapse Free Survival (RFS).

Exploratory Endpoints: For Indications A and B: (1) Incidence of anti-AMG 757 antibody formation, (2) Changes in protein, nucleic acid and cellular biomarkers in blood (e.g., cytokines, lymphocyte status, CTCs, sDLL3), (3) Cell surface protein expression (e.g., DLL3) and tumor infiltrating lymphocyte status in tumor tissue at baseline. For Indication B only: Effect of prior chemotherapy on T cell cytokine production pre-AMG 757 treatment. For Par C only: incidence of CRS.

Example 5 Effects in Humans

Pharmacokinetics in humans: Preliminary AMG 757 PK analysis using noncompartmental approach was conducted for subjects in cohorts 1 to 5. Preliminary PK results show that AMG 757 exposures increased with dose from 0.003 mg to 0.3 mg. Estimated terminal half-life (t½) is approximately a week across doses after multiple Q2W dosing. No significant accumulation was observed (< 2-fold).

There was one confirmed response at 0.3 mg IV Q2W (cohort 5).

Antitumor activity was assessed using modified Response Evaluation Criteria in Solid Tumors (RECIST) 1.1; assessments were performed at screening and every 8 ± 1 weeks after AMG 757 treatment until disease progression, withdrawal of consent, or start of new anticancer therapy.

40 patients (median age [range], 64 years [44-80]; ECOG PS: 0-1, n=39 [97.5%], median prior lines: 2.0 [1-6]; prior PD-⅟PD-L1 treatment: n=17 [42.5%]) enrolled at eight dose levels (DL) received ≥1 dose of AMG 757. Median treatment duration was 6.1 weeks (0.1-59.4). Adverse events (AEs) occurred in 39 (97.5%) patients, resulting in discontinuation in 4 (10.0%); 32 (80.0%) were treatment-related, including 7 (17.5%) grade ≥3 and 1 (2.5%) grade 5 (pneumonitis; DL5 [0.3 mg]). Cytokine release syndrome (CRS) was reported in 18 (45.0%) patients; grade 2 CRS in 5 (12.5%); no grade ≥3 CRS. CRS presented mainly as fever ± hypotension, was reversible, did not lead to treatment interruption or discontinuation, occurred mostly within 24 hours of the first two doses of AMG 757, and was managed with supportive care, corticosteroids, and/or anti-IL-6 treatment. 6 (17.6%) patients developed treatment-emergent anti-AMG 757 binding antibodies. The anti-AMG 757 antibodies were not associated with AEs and had no clear effect on drug exposure. Mean (+SD) steady state serum Concentration-Time profiles of AMG 757 are shown in FIG. 5. AMG 757 showed dose proportional increase in exposures (FIG. 5).

Confirmed partial response (PR) was reported for 6 (15.8%) patients (1/12 [8.3%] in DL5, ⅛ [12.5%] in DL6, 3/7 [42.9%] in DL7, and ⅐ [14.3%] in DL8 [FIG. 4]). Stable disease was reported for 11 (28.9%), including 1 patient with ongoing unconfirmed PR in DL8. Patients with confirmed PR had a median of 2 (1-4) prior lines of therapy and duration of response of 1.9+ to 9.4+ months. DLL3 expression at any level was observed in 31/32 (96.9%) patient tumor samples, with overall H-score 40-300. Tumor shrinkage occurred across a wide range of DLL3 expression (H-score, 55-300). The results show that AMG 757 has acceptable safety at doses of up to 10 mg and shows anti-tumor activity in patients with SCLC.

59 patients enrolled in ten dose levels (DL) received ≥1 dose of AMG 757. Summary of Objective Response of the patients who met the overall response rate (ORR) analysis criteria at the relevant data cut off day is shown in FIG. 6. Confirmed partial response (PR) was reported for 7 (14.6%) patients (1/12 [8.3%] in DL5, ⅛ [12.5%] in DL6, 3/7 [42.9%] in DL7, 2/10 [20%] in DL8, and 0/7 [0%] in DL 9 [FIG. 6]). Stable disease was reported for 12 (25%) including two in Cohort 9 (2/7 [28.6%]). One grade 3 CRS was observed in one patient in cohort 9 and was managed with supportive care, corticosteroids, and vasopressor treatment. The results show that AMG 757 has acceptable safety at doses of up to 30 mg and shows anti-tumor activity in patients with SCLC.

Seven patients enrolled in Cohort 10 received ≥1 dose of AMG 757 with 4 subjects received 100 mg (on day 8) at least once. No new safety signals were observed in these patients compared to earlier cohorts.
