The invention relates to methods for treatment of cancer, especially a breast cancer, using a combination of medicaments, thereby targeting multiple pathways.
Cancer is a leading cause of death worldwide, accounting for an estimated total of 9.6 million deaths in 2018. The most common cancers are lung cancer, breast cancer and colorectal cancers, while lung cancer, colorectal cancer and stomach cancer are the most common causes of cancer death (The Global Cancer Observatory, 2019. Factsheet on cancers/39).
Early diagnosis and treatment of cancer may provide significant improvement to the lives of cancer patients. Some of the most common cancer types, such as breast cancer and colorectal cancer, have high cure rates when detected and treated at an early stage, before cancer cells have metastasized.
Although early stage breast cancer has a relative good prognosis, still approximately 30% of patients would develop a distant metastasis and die from the disease if not treated with adjuvant therapy after surgery (Rosen et al., 1989. J Clin Oncol 7: 355-366). It is common to treat hormone receptor positive breast cancer with adjuvant endocrine therapy. There are clinical factors such as size and grade and genomic signatures used by clinicians to identify patients who need adjuvant chemotherapy.
Breast cancer cells can be classified into molecular subtypes basal, luminal and HER2 positive, by simple hierarchical clustering of breast tumors according to their gene expression patterns (Perou et al., 2000. Nature 406: 747-7520. In general, these subtypes represent the Estrogen Receptor (ER), Progesterone Receptor (PR) and Human Epidermal growth factor Receptor 2 (HER2) status of the tumor: Basal-like breast cancers correlate best with triple negative (ER-negative, PR-negative, and HER2-negative tumors) breast cancers (Rakha et al., 2009. Clin Cancer Res 15: 2302-2310; Carey et al., 2007. Clin Cancer Res 13: 2329-2334). Luminal-like cancers are ER-positive (Nielsen et al., 2004. Clin Cancer Res 10: 5367-5374) and HER2 positive cancers have a high expression of the HER2 gene (Kauraniemi and Kallioniemi. 2006. Endocr Relat Cancer 13: 39-49). While this classification system has been developed without consideration of patient survival rates, the different molecular subtypes of breast cancer have different prognoses: luminal-like tumors have a more favorable outcome and basal-like and HER2 subgroups appear to be more sensitive to chemotherapy (Sorlie et al., 2001. Proc Natl Acad Sci USA 98: 10869-10874; Rouzier et al., 2005. Clin Cancer Res 11: 5678-5685; Liedtke et al., 2008. J Clin Oncol 26: 1275-1281; Krijgsman et al., 2012. Breast Cancer Res Treat 133: 37-47).
Patients with positive HER2 receptor usually receive anti HER2 therapy. Despite these treatment options there are still too many breast cancer patients that develop distant metastasis. New therapeutics are developed to target specific pathway defects in early stage breast cancer. Two classes that are tested are PARP inhibitors and PD-1/PDL-1 inhibitors. Some have shown promising effects in metastatic breast cancer. These classes are primarily tested in hormone receptor (ER and PR) negative breast cancer, such as BRCA-mutated breast cancers. These cancers often have a DNA repair deficient phenotype which might make them sensitive for PARP inhibitions. The genomic instability caused by DNA repair deficiency also causes these tumors to accumulate more mutations and therefor are easier to recognize by the patient's immune system which makes these tumors potentially sensitive for PD-1/PDL-1 inhibitors (Robson et al., 2017. N Engl J Med 377: 523-533; Schmid et al., 2018. N Engl J Med 379: 2108-2121).
Hormone receptor positive breast cancer does not often represent these phenotypes and PARP and PD-1 have shown little success in HR+ breast cancer.
The I-SPY 2 TRIAL (NCT01042379), sponsored by Quantum Leap Healthcare Collaborative, is a standing Phase 2 randomized, controlled, multi-center trial for women with newly diagnosed, locally advanced breast cancer (Stage II/III), and is designed to screen promising new treatments and identify which therapies are most effective in specific patient subgroups based on molecular characteristics (biomarker signatures). The trial is an adaptive study design assessing the combination of biologically targeted investigational drugs with standard chemotherapy in the neoadjuvant setting, compared to standard chemotherapy alone. The primary endpoint is to determine whether the combination of certain therapies increases the probability of pathological complete response (pCR) in the breast and the lymph nodes at the time of surgery (Barker et al., 2009. Clin Pharmacol Ther 86: 97-100).
Results from this program have shown that a combination of a PARP inhibitor (veliparib) and a platinum-based antineoplastic drug (carboplatin) increased pCR rates in the triple-negative subgroup to 51%, versus 26% in the control group (Rugo et al., 2016. New Engl J Med 375: 23-34). Additional data showed that a 7-gene DNA repair deficiency expression signature (PARPi-7; Daemen et al., 2012. Breast Cancer Res Treat 135: 505-517), BRCAlness and MammaPrint® signatures may help refine predictions of VC response, thereby improving patient care (Van't Veer et al., 2015. J Clin Oncol 33: 521-521; Wolf et al., 2017. NPJ Breast Cancer 3: 31). In addition, the immune check point inhibitor pembrolizumab, when added to standard neoadjuvant chemotherapy, more than doubled the estimated pCR rates for both ERBB2-negative (HER2-negative) breast cancer (Nanda et al., 2020. JAMA Oncology: doi: 10.1001/jamaonco1.2019.6650).
However, there is a need for new treatment options, including new combinations of agents, that could provide therapeutic benefit for specific cancer patients, especially Her2 negative breast cancer patients. Additionally, there is a need to identify cancer patients that might benefit from new treatment options, including new combinations of agents.

As is used herein, the term “BluePrint®” (U.S. Pat. Nos. 9,175,351; 10,072,301; Krijgsman et al., 2012. Br Can Res Treatm 133: 37-47) refers to a molecular subtyping test, analyzing the activity of 80 genes to enable stratification of a breast cancer into one of the three following subtypes: Luminal-type, HER2− type and Basal-type.
The term “RNA expression product”, as used herein, refers to an expression product of a gene and includes gene expression products such as RNA, including mRNA. Also included in this term are complementary nucleic acids derived from a RNA gene expression product, such as cDNA and cRNA. Preferably, the gene expression products in a sample from a cancer patient are RNA expression products, including mRNA, cDNA and cRNA.
A gene signature test (MammaPrint®, MP), also termed “Amsterdam gene signature test” determines the expression of gene expression products of signature genes and stratifies early-stage breast cancer patients in Low- and High risk for developing distant metastases within 5 years after diagnosis. Extensive validation studies (Drukker et al., 2013. Int J Cancer 133: 929-936; Bueno-de-Mesquita et al., 2007. Lancet Oncol 8: 1079-1087; van de Vijver et al., 2002. New Engl J Med 34: 1999-2009) and the recent MINDACT clinical trial (Cardoso et al., 2016. N Engl J Med 375: 717-729) have demonstrated the clinical utility of MammaPrint (level 1A clinical evidence), making it a unique example of a clinical diagnostic test that helps guide physicians in adjuvant treatment decisions for breast cancer patients.
A sample from a cancer patient comprising gene expression products from a cancer cell of said patient can be obtained in numerous ways, as is known to a person skilled in the art. In a method of the invention, a sample can be obtained directly from the individual, for example by taking a biopsy from the cancer.
Said sample may also be obtained from a breast cancer after removal of the cancer, or at least part of the cancer, from a patient. Said sample is preferably obtained from a cancer within two hours after removal, more preferably within 1 hour after removal of the cancer or part of the cancer.
Before a sample comprising gene expression products is obtained from a cancer, said cancer may be cooled and stored at about 0-8° C. The sample can be freshly prepared from cells or a tissue sample at the moment of harvesting, or they can be prepared from samples that are stored at −70° C. until processed for sample preparation.
Alternatively, tissues or biopsies can be stored under conditions that preserve the quality of protein or RNA. Examples of these preservative conditions are fixation using e.g. formaline and paraffin embedding, RNase inhibitors such as RNAsin (Pharmingen) or RNasecure (Ambion), aquous solutions such as RNAlater (Assuragen; U.S. Ser. No. 06/204,375), Hepes-Glutamic acid buffer mediated Organic solvent Protection Effect (HOPE; DE10021390), and RCL2 (Alphelys; WO04083369), and non-aquous solutions such as Universal Molecular Fixative (Sakura Finetek USA Inc.; U.S. Pat. No. 7,138,226). Alternatively, a sample from a cancer patient may be fixated in formalin, for example as formalin-fixed paraffin-embedded (FFPE) tissue. Preferably, the sample is an FFPE sample.
Methods to determine gene expression levels of genes are known to a skilled person and include, but are not limited to, Northern blotting, quantitative PCR, microarray analysis and RNA sequencing.
It is preferred that said gene expression levels are determined simultaneously. Simultaneous analyses can be performed, for example, by multiplex qPCR, RNA sequencing procedures, and microarray analysis. Microarray analysis allow the simultaneous determination of gene expression levels of expression of a large number of genes, such as more than 50 genes, more than 100 genes, more than 1000 genes, more than 10.000 genes, or even whole-genome based, allowing the use of a large set of gene expression data for normalization of the determined gene expression levels in a method of the invention.
Microarray-based analysis involves the use of selected biomolecules that are immobilized on a solid surface, an array. A microarray usually comprises nucleic acid molecules, termed probes, which are able to hybridize to gene expression products. The probes are exposed to labeled sample nucleic acid, hybridized, and the abundance of gene expression products in the sample that are complementary to a probe is determined. The probes on a microarray may comprise DNA sequences, RNA sequences, or copolymer sequences of DNA and RNA. The probes may also comprise DNA and/or RNA analogues such as, for example, nucleotide analogues or peptide nucleic acid molecules (PNA), or combinations thereof. The sequences of the probes may be full or partial fragments of genomic DNA. The sequences may also be in vitro synthesized nucleotide sequences, such as synthetic oligonucleotide sequences.
In the context of the invention, a probe is to be specific for a gene expression product of a gene as listed in Table 1. A probe is specific when it comprises a continuous stretch of nucleotides that are completely complementary to a nucleotide sequence of a gene expression product, or a cDNA product thereof. A probe can also be specific when it comprises a continuous stretch of nucleotides that are partially complementary to a nucleotide sequence of a gene expression product of said gene, or a cDNA product thereof. Partially means that a maximum of 5% from the nucleotides in a continuous stretch of at least 20 nucleotides differs from the corresponding nucleotide sequence of a gene expression product of said gene. The term complementary is known in the art and refers to a sequence that is related by base-pairing rules to the sequence that is to be detected. It is preferred that the sequence of the probe is carefully designed to minimize nonspecific hybridization to said probe.
It is preferred that the probe is, or mimics, a single stranded nucleic acid molecule. The length of said complementary continuous stretch of nucleotides can vary between 15 bases and several kilo bases, and is preferably between 20 bases and 1 kilobase, more preferred between 40 and 100 bases, and most preferred about 60 nucleotides. A most preferred probe comprises about 60 nucleotides that are identical to a nucleotide sequence of a gene expression product of a gene, or a cDNA product thereof. In a method of the invention, probes comprising probe sequences as indicated in Tables 1-2 can be employed.
To determine the RNA expression level by micro-arraying, gene expression products in the sample are preferably labeled, either directly or indirectly, and contacted with probes on the array under conditions that favor duplex formation between a probe and a complementary molecule in the labeled gene expression product sample. The amount of label that remains associated with a probe after washing of the microarray can be determined and is used as a measure for the gene expression level of a nucleic acid molecule that is complementary to said probe.
The determined RNA expression level can be normalized for differences in the total amounts of nucleic acid expression products between two separate samples by comparing the level of expression of one or more genes that are known not to differ in expression level between samples. If samples for use in a method of the invention are FFPE samples, it is possible to use an FFPE normalization template.
A preferred method for determining RNA expression is by microarray analysis.
Another preferred method for determining RNA expression levels is by sequencing, preferably next-generation sequencing (NGS), of RNA samples, with or without prior amplification of the RNA expression products.
High throughput sequencing techniques for sequencing RNA have been developed. NGS platforms, including Illumina® sequencing; Roche 454 Pyrosequencing®, ion torrent and ion proton sequencing, and ABI SOLID® sequencing, allow sequencing of fragments of DNA in parallel. Bioinformatics analyses are used to piece together these fragments by mapping the individual reads. Each base is sequenced multiple times, providing high depth to deliver accurate data and an insight into unexpected DNA variation. NGS can be used to sequence a complete exome including all or small numbers of individual genes.
Pyrosequencing detects the release of inorganic pyrophosphate (PPi) as particular nucleotides are incorporated into the nascent strand (Ronaghi et al., 1996. Analytical Biochemistry 242: 84-9; Ronaghi, 2001. Genome Res 11: 3-11; Ronaghi et al., 1998. Science 281: 363; U.S. Pat. Nos. 6,210,891; 6,258,568; and 6,274,320, which are all incorporated herein by reference. In pyrosequencing, released PPi can be detected by being immediately conversion to adenosine triphosphate (ATP) by ATP sulfurylase, and the level of ATP generated is detected via luciferase-produced photons.
NGS also includes so called third generation sequencing platforms, for example nanopore sequencing on an Oxford Nanopore Technologies platform, and single-molecule real-time sequencing (SMRT sequencing) on a PacBio platform, with or without prior amplification of the RNA expression products.
Further high throughput sequencing techniques include, for example, sequencing-by-synthesis. Sequencing-by-synthesis or cycle sequencing can be accomplished by stepwise addition of nucleotides containing, for example, a cleavable or photobleachable dye label as described, for example, in U.S. Pat. Nos. 7,427,673; 7,414,116; WO 04/018497; WO 91/06678; WO 07/123744; and U.S. Pat. No. 7,057,026, all of which are incorporated herein by reference.
Sequencing techniques also include sequencing by ligation techniques. Such techniques use DNA ligase to incorporate oligonucleotides and identify the incorporation of such oligonucleotides and are inter alia described in U.S. Pat. Nos. 6,969,488; 6,172,218; and 6,306,597. Other sequencing techniques include, for example, fluorescent in situ sequencing (FISSEQ), and Massively Parallel Signature Sequencing (MPSS).
Sequencing techniques can be performed by directly sequencing RNA, or by sequencing a RNA-to-cDNA converted nucleic acid library. Most protocols for sequencing RNA samples employ a sample preparation method that converts the RNA in the sample into a double-stranded cDNA format prior to sequencing. Conversion of RNA into cDNA and/or cRNA using a reverse-transcriptase enzyme such as M-MLV reverse-transcriptase from Moloney murine leukemia virus, or AMV reverse-transcriptase from avian myeloblastosis virus, is known to a person skilled in the art.
In the methods of diagnosing, the reference sample preferably is a sample, such as an RNA sample, isolated from a tissue of a healthy individual, or isolated from a cancerous growth of a cancer patient, preferably a breast cancer patient. The reference sample may comprise an RNA sample from a relevant cell line or mixture of cell lines. The RNA from a cell line or cell line mixture can be produced in-house or obtained from a commercial source such as, for example, Stratagene Human Reference RNA. Another preferred reference sample comprises RNA isolated and pooled from normal adjacent tissue from cancer patients.
Even more preferably, said reference sample is a pooled RNA sample that is isolated from tissue comprising cancer cells from multiple individuals suffering from cancer, preferably breast cancer, more preferably stage 2 and/or 3 breast cancer, and which cancer cells either have an activated or not activated PD1. It is preferred that said sample is pooled from more than 10 individuals, more preferred more than 20 individuals, more preferred more than 30 individuals, more preferred more than 40 individuals, most preferred more than 50 individuals.
Typing of a sample can be performed in various ways. In one method, a coefficient is determined that is a measure of a similarity or dissimilarity of a sample with a previously established reference RNA expression level of the target genes that is specific to a certain cell type, tissue, disease state or any other interesting biological or clinical interesting samples group. Such a reference RNA expression level can be referred to as a profile template. Typing of a sample can be based on its (dis)similarity to a single profile template or based on multiple profile templates. In the invention, the profile templates are representative of samples that have low risk outcome, high risk outcome, or both low risk and high risk outcome. Examples of suitable profile templates are RNA expression level templates of a single breast cancer sample from a patient with low or high risk outcome, preferably a group of at least 10, 30, 40, 50, 100, 200 or 300 breast cancer patients with low and/or high risk outcome.
A number of different coefficients can be used for determining a correlation between the gene expression level in a sample from a cancer patient and a profile template. Preferred methods are parametric methods which assume a normal distribution of the data. One of these methods is the Pearson product-moment correlation coefficient, which is obtained by dividing the covariance of the two variables by the product of their standard deviations. Preferred methods comprise cosine-angle, un-centered correlation and, more preferred, cosine correlation (Fan et al., Conf Proc IEEE Eng Med Biol Soc. 5:4810-3 (2005)).
Said correlation with a profile template is used to produce an overall similarity score for the set of genes that are used. A similarity score is a measure of the average correlation of gene expression levels of a set of genes in a sample from a cancer patient and a profile template. Said similarity score can, but does not need to be, a numerical value between +1, indicative of a high correlation between the gene expression level of the set of genes in a sample of said cancer patient and said profile template, and −1, which is indicative of an inverse correlation. A threshold can be used to differentiate between samples having low risk outcome, and samples having high risk outcome. Said threshold is an arbitrary value that allows for discrimination between samples from patients with low risk outcome, and samples of patients with high risk outcome. If a similarity threshold value is employed, it is preferably set at a value at which an acceptable number of patients with high risk outcome would score as false negatives, and an acceptable number of patients with low risk outcome would score as false positives. A similarity score is preferably displayed or outputted to a user interface device, a computer readable storage medium, or a local or remote computer system.
A method of typing of the invention may further comprise determining a stage of the cancer. The staging of a cancer is generally based on the size of the cancer and on whether the cancer has spread to lymph nodes or other areas of the body.
A preferred staging system is the TNM (for tumors/nodes/metastases) system, from the American Joint Committee on Cancer (AJCC). The TNM system assigns a number based on three categories. “T” denotes the size of the tumor, “N” the degree of lymphatic node involvement, and “M” the degree of metastasis.
The methods of assigning a PARP inhibitor, an immune checkpoint inhibitor, and a combination of a PARP inhibitor and an immune checkpoint inhibitor to a HER2 negative breast cancer patient further comprise determining a level of RNA expression for a plurality of genes consisting of at least 5 of the genes for which markers are listed in Table 1 in a sample comprising RNA expression products from a cancer cell of the patient.
MammaPrint® (MP) is a 70 genes-based assay, as described in WO2002103320, which is hereby incorporated by reference. MP reports a risk of cancer recurrence within a period of 5 years without adjuvant chemotherapy. MP is intended to classify an individual suffering from breast cancer as having a good prognosis having no distant metastases within five years of initial diagnosis (low risk outcome), or as having a poor prognosis having distant metastases within five years of initial diagnosis (high risk outcome).
MP was shown to successfully predict metastasis free survival and overall survival in retrospective and prospective studies (van de Vijver et al., 2002. N Engl J Med 347: 1999-2009; van't Veer et al., 2002. Nature 415: 530-536; Drukker et al., 2013. Int J Cancer 133: 929-936; Cardoso et al., 2016. N Engl. J Med 375: 717-729).
The MammaPrint high risk group can be further divided into 2 groups by taking the median MammaPrint index of the high risk samples. MammaPrint high risk group 2 (MP2) is defined as having a MammaPrint index higher than the median value, while MP1 is defined as having a MammaPrint index lower than the median value
It was now surprisingly found that MP may also be used to predict a response to a PARP inhibitor, an immune checkpoint inhibitor, and to a combination of a PARP inhibitor and an immune checkpoint inhibitor of a HER2 negative breast cancer patient. More specifically, an individual suffering from a HER2 negative breast cancer and typed as having MammaPrint high risk group 2 (MP2), thus with a poor prognosis, is likely to provide a pathological complete response (pCR) upon treatment with mediated therapy.
A method of the invention for predicting a response to a PARP inhibitor, an immune checkpoint inhibitor, or to the combination thereof, of HER2-negative breast cancer involves the use of at least 5 genes indicated in Table 1, more preferred at least 6 genes, more preferred at least 7 genes, more preferred at least 8 genes, more preferred at least 9 genes, more preferred at least 10 genes, more preferred at least 20 genes, more preferred at least 30 genes, more preferred at least 40 genes, more preferred at least 50 genes, more preferred at least 60 genes, more preferred at least 70 genes indicated in Table 1, such as all 231 genes listed in Table 1.
The set of genes selected from the genes listed in Table 1 preferably contains at least the first 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95 or 100 rank-ordered genes of Table 1. The genes in Table 1 were rank-ordered according to the agreement of the outcome of typing of a sample with the individual genes to the outcome of the typing of a sample with the set of genes listed in Table 2. A preferred set of genes comprises both positively correlated genes as well as negatively correlated genes, as indicated in Table 1, whereby said correlation is to a good prognosis signature.
A further preferred set of genes according to the invention comprises at least five genes of Table 1 that are rank-ordered 1-5 and/or 227-231. A further preferred set of genes according to the invention comprises at least ten genes of Table 1 that are rank-ordered 1-10 and/or 222-231, more preferred at least twenty genes listed in Table 1 that are rank-ordered 1-20 and/or 212-231; more preferred at least fifty genes listed in Table 1 that are rank-ordered 1-50 and/or 182-231; more preferred at least hundred genes listed in Table 1 that are rank-ordered 1-100 and/or 132-231; more preferred all 231 genes listed in Table 1.
A preferred set of genes for predicting a response to a PARP inhibitor, an immune checkpoint inhibitor, or to the combination thereof, of HER2-negative breast cancer involves the use of a subset of 70 genes, which are indicated in Table 2 and for which preferred probes are provided in Table 2.
A further preferred method of the invention for predicting a response to a PARP inhibitor, an immune checkpoint inhibitor, or to the combination thereof, of HER2-negative breast cancer involves the use of at least 5 genes indicated in Table 2, more preferred at least 6 genes, more preferred at least 7 genes, more preferred at least 8 genes, more preferred at least 9 genes, more preferred at least 10 genes, more preferred at least 20 genes, more preferred at least 30 genes, more preferred at least 40 genes, more preferred at least 50 genes, more preferred at least 60 genes, more preferred all 70 genes indicated in Table 2.
A further preferred set of genes according to the invention comprises at least five genes of Table 2 that are rank-ordered 1-5 and/or 66-70. A further preferred set of genes according to the invention comprises at least ten genes of Table 2 that are rank-ordered 1-10 and/or 61-70, more preferred at least twenty genes listed in Table 2 that are rank-ordered 1-20 and/or 51-70; more preferred at least fifty genes listed in Table 2 that are rank-ordered 1-50 and/or 21-70; more preferred all 70 genes listed in Table 2.
It is noted that some probes hybridize to the same genes indicated in Table 2, such as three probes which are now known to hybridize to expression products of the Diaphanous Related Formin 3 (DIAPH3; ENSG00000139734) gene. A reference to different genes listed in Table 2 includes reference to different probes hybridizing to the same gene listed in Table 2. Hence, the term “at least five genes of Table 2” provides reference to both 5 different genes listed in Table 2 as well as 5 different probes listed in Table 2.

Said protocol may include daily or weekly administration for 1-30 days, such as 2 days, 10 days, 21 days, or 28 days, followed by period of 0-14 days, such as 7 days in which no inhibitor is administered. As an alternative, said daily or weekly administration may be followed by another therapy, for example a combination of doxorubicin (60 mg/m2) and cyclophosphamide (600 mg/m2) for 4 cycles every 3 weeks.
A combination comprising a PARP inhibitor and an immune checkpoint inhibitor according to the invention may further be combined with a taxane. Said taxane preferably is administered in the same time frame as the PARP inhibitor and the immune checkpoint inhibitor are administered, for example in a period of 1-30 days, such as 2 days, 10 days, 21 days, or 28 days.
Said taxane preferably is administered intravenously, preferably by infusion. Said taxane preferably is repeatedly administered, for example once every week, once every two weeks, or once every three weeks. For example, paclitaxel may be administered at a dosage of 75-200 mg/m2, such as about 80 mg/m2, every 1-4 weeks; docetaxel may be administered at a dosage of 40-100 mg/m2, such as about 60 mg/m2, every 1-4 weeks; and cabazitaxel may be administered at a dosage of 5-75 mg/m2, such as about 20 mg/m2, every 1-4 weeks.
A combination of a PARP inhibitor and an immune checkpoint inhibitor according to the invention may be provided in one pharmaceutical preparation or, preferably, as two or more distinct pharmaceutical preparations. Said distinct pharmaceutical preparations may further comprise pharmaceutically acceptable excipients, as is known to a person skilled in the art.
Pharmaceutically acceptable excipients include diluents, binders or granulating ingredients, a carbohydrate such as starch, a starch derivative such as starch acetate and/or maltodextrin, a polyol such as xylitol, sorbitol and/or mannitol, lactose such as α-lactose monohydrate, anhydrous α-lactose, anhydrous β-lactose, spray-dried lactose, and/or agglomerated lactose, a sugar such as dextrose, maltose, dextrate and/or inulin, or combinations thereof, glidants (flow aids) and lubricants to ensure efficient tableting, and sweeteners or flavors to enhance taste.

For the purpose of clarity and a concise description, features are described herein as part of the same or separate aspects and preferred embodiments thereof, however, it will be appreciated that the scope of the invention may include embodiments having combinations of all or some of the features described.
The invention will now be illustrated by the following examples, which are provided by way of illustration and not of limitation and it will be understood that many variations in the methods described and the amounts indicated can be made without departing from the spirit of the invention and the scope of the appended claims.
A total of 372 breast cancer samples of patients with breast cancer having a High Risk MammaPrint outcome were entered into an I-SPY 2 trial. Additional criteria were a tumor size larger than 2.5 cm, adequate organ function as measured by a Performance Status (PS) score <2 (Eastern Cooperative Oncology Group scale; Oken et al., 1982. Am J Clin Oncol 5: 649-655), agreement to undergo MRI analyses and surgery following chemotherapy, and consent to analysis of biopsy samples.
A total of 299 MammaPrint High Risk patients were randomized as controls and treated with standard chemotherapy: First paclitaxel 80 mg/m2 every week for 12 weeks, followed by doxorubicin (60 mg/m2) and cyclophosphamide (600 mg/m2) for 4 cycles every 3 weeks.
A total of 73 MammaPrint High Risk patients were concurrently randomized to receive a combination of duvalumab and olaparib, in addition to paclitaxel 80 mg/m2 every week for 12 weeks, followed by doxorubicin (60 mg/m2) and cyclophosphamide (600 mg/m2) for 4 cycles every 3 weeks. Specifically, duvalumab 1500 mg was administered every 4 weeks for a total of 3 cycles; olaparib 100 mg was administered twice daily in the first 12 weeks.
The MammaPrint high risk group was further divided into 2 groups by taking the median MammaPrint index of the high risk samples (MP1 and MP2). MammaPrint high risk group 2 (MP2) is defined as having a MammaPrint index higher than the median value, while MP1 is defined as having a MammaPrint index lower than the median value (Wolf et al., 2017. NPJ Breast Cancer 3: 1-9). In total 209 patients were analyzed, 132 HR+HER2− patients were classified as MP1 of which 24 were randomized to the Duvalumab/Olaparib arm and 108 to the control arm. The remaining 77 HR+HER2− patients were classified as MP2. 28 of the MP2 patients were randomized to the Duvalumab/Olaparib arm and 49 to the control arm.
Patient and baseline clinical characteristics, ethnicity, HR status, tumor size and nodal status (see Table 3), were similar between the experimental and control arms.
The primary endpoint was pathologic complete response @CR), i.e., no invasive cancer left in the breast or lymph nodes. Hormone receptor (HR; progesterone and estradiol receptor) status and HER2 status were determined by molecular subtyping (e.g. BluePrint; Krijgsman et al., 2012. Breast Cancer Res Treat 133: 37-47; Mittempergher et al., 2020. Transl Oncol. 13: 100756); immunohistochemistry and/or fluorescent in situ hybridization.
Patients who received non-protocol therapy, left their treating institution, or withdrew consent prior to surgery were considered non-pCR as per protocol.
MammaPrint high risk classification associated with response in the Duvalumab/Olaparib arm in in Her2 negative subtype, but not in the control. Bayesian modeling (Gelman et al., 2019. J American Statistician 73: 307-309) was used to estimate the pCR probabilities to Duvalumab/Olaparib and standard chemotherapy in the HER2 negative subset. This was performed similar to the I-SPY 2 primary efficacy analysis (Barker et al., 2009. Clin Pharmacol Therapeutics 86: 97-100). As shown in
The Her2 negative subtype was further analyzed for hormone positive and hormone negative subtypes. MammaPrint High Risk classification in the Hormone negative and in the HER2 negative subgroup associated with response in the Duvalumab/Olaparib arm, but not in the control. Similarly, in the Hormone positive, HER2 negative, subtype, MammaPrint High Risk classification associated with response in the Duvalumab/Olaparib arm, but not in the control group.
Bayesian modeling was also used to estimate the pCR probabilities to Duvalumab/Olaparib and standard chemotherapy in the Hormone negative, HER2 negative subtype (HR−Her2−). As is shown in
Table 4 shows the probability of Duvalumab/Olaparib demonstrating superiority to control in a 1:1 randomized neoadjuvant phase 3 trial of 300 biomarker predicted-sensitive patients. These probabilities are >98% (99.9% for MammaPrint High Risk in Her2 negative subgroup, 98.4% for MammaPrint high risk in the HR−/Her2− subtype, 99.6% for MammaPrint High risk in the HR+/Her2-subtype).
The predictive probability for success in a randomized phase 3 trial is 81.4% in the HER2 negative subtype, 80.6 in the Her2negative/hormone negative subtype and 74.5% in the Hormone positive/HER2negative subtype.
Residual Cancer Burden (RCB) after neoadjuvant chemotherapy has been shown to be an accurate long-term predictor of disease recurrence and survival across all breast cancer subtypes (Symmans et al., 2007. J Clin Oncol 24: 536). In addition to complete response, RCB is reduced in patients that were MammaPrint high risk and treated with Duvalumab/Olaparib. RCB shifted to lower values across all RCB categories in all subtypes, except RCBIII in HR−/HER2− subtype (
MammaPrint high risk 2 group (MP2) drives the benefit of Duvalumab/Olaparib in the HR+HER2− subtype (
The probability of MP2 patients treated with Duvalumab/Olaparib demonstrating superiority to control in a 1:1 randomized neoadjuvant phase 3 trial of 300 biomarker predicted-sensitive patients was calculated. These probabilities are 99.9% for MammaPrint High Risk2 (MP2) in HR+HER2− subgroup, and 33.1% in the MP1 subgroup (
