On December 17, 2018 Bristol-Myers Squibb Company (NYSE:BMY) reported that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency has recommended the expanded approval of Sprycel (dasatinib), in combination with chemotherapy, to include the treatment of pediatric patients with newly diagnosed Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL) (Press release, Bristol-Myers Squibb, DEC 17, 2018, View Source [SID1234532093]). The positive opinion includes the tablet form of Sprycel and the powder for oral suspension formulation, which was first approved by the European Commission (EC) in July 2018, making Sprycel the only tyrosine kinase inhibitor with a formulation developed for administration in pediatric patients and patients who cannot swallow tablets. The CHMP recommendation will now be reviewed by the EC, which has the authority to approve medicines for the European Union (EU).

"We are pleased with today’s CHMP recommendation for Sprycel in pediatric patients with Ph+ ALL, and look forward to the possibility of expanding Sprycel’s pediatric indications in the EU to include young patients with this particularly high-risk leukemia," said Fouad Namouni, M.D., head, oncology development, Bristol-Myers Squibb.

The application is based on data from CA180-372 (NCT01460160), an ongoing Phase 2 trial evaluating the addition of Sprycel to a chemotherapy regimen modeled on a Berlin-Frankfurt-Munster high-risk backbone in pediatric patients with newly diagnosed Ph+ ALL.

About Sprycel

Sprycel first received FDA approval in 2006 for the treatment of adults with Philadelphia chromosome-positive (Ph+) chronic myeloid leukemia (CML) in chronic phase (CP) who are resistant or intolerant to prior therapy including imatinib. At that time, Sprycel also received FDA approval for adults with Ph+ acute lymphoblastic leukemia (ALL) who are resistant or intolerant to prior therapy. Sprycel is approved and marketed for these indications in more than 60 countries.

Sprycel is also an FDA-approved treatment for adults with newly diagnosed Ph+ CML-CP and is approved for this indication in more than 50 countries.

Both the FDA and the European Commission approved the expansion of Sprycel’s indication to include pediatric patients with Ph+ CML-CP in November 2017 and July 2018.

U.S. FDA-APPROVED INDICATIONS FOR SPRYCEL

SPRYCEL (dasatinib) is indicated for the treatment of adults with:

Newly diagnosed Philadelphia chromosome-positive (Ph+) chronic myeloid leukemia (CML) in chronic phase
Chronic, accelerated, or myeloid or lymphoid blast phase Ph+ CML with resistance or intolerance to prior therapy including imatinib
Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) with resistance or intolerance to prior therapy
SPRYCEL is indicated for the treatment of pediatric patients with:

Ph+ CML in chronic phase
IMPORTANT SAFETY INFORMATION

Myelosuppression

Treatment with SPRYCEL is associated with severe (NCI CTCAE Grade 3/4) thrombocytopenia, neutropenia, and anemia, which occur earlier and more frequently in patients with advanced phase CML or Ph+ ALL than in patients with chronic phase CML. Myelosuppression was reported in patients with normal baseline laboratory values as well as in patients with pre-existing laboratory abnormalities.

In patients with chronic phase CML, perform complete blood counts (CBCs) every 2 weeks for 12 weeks, then every 3 months thereafter, or as clinically indicated
In patients with advanced phase CML or Ph+ ALL, perform CBCs weekly for the first 2 months and then monthly thereafter, or as clinically indicated
Myelosuppression is generally reversible and usually managed by withholding SPRYCEL temporarily and/or dose reduction
In clinical studies, myelosuppression may have also been managed by discontinuation of study therapy
Hematopoietic growth factor has been used in patients with resistant myelosuppression
Bleeding-Related Events

SPRYCEL can cause serious and fatal bleeding. In all CML or Ph+ ALL clinical studies, Grade ≥3 central nervous system (CNS) hemorrhages, including fatalities, occurred in <1% of patients receiving SPRYCEL. The incidence of Grade 3/4 hemorrhage, occurred in 5.8% of adult patients and generally required treatment interruptions and transfusions. The incidence of Grade 5 hemorrhage occurred in 0.4% of adult patients. The most frequent site of hemorrhage was gastrointestinal.

Most bleeding events in clinical studies were associated with severe thrombocytopenia
In addition to causing thrombocytopenia in human subjects, dasatinib caused platelet dysfunction in vitro
Concomitant medications that inhibit platelet function or anticoagulants may increase the risk of hemorrhage
Fluid Retention

SPRYCEL may cause fluid retention. After 5 years of follow-up in the adult randomized newly diagnosed chronic phase CML study (n=258), grade 3/4 fluid retention was reported in 5% of patients, including 3% of patients with grade 3/4 pleural effusion. In adult patients with newly diagnosed or imatinib resistant or intolerant chronic phase CML, grade 3/4 fluid retention occurred in 6% of patients treated with SPRYCEL at the recommended dose (n=548). In adult patients with advanced phase CML or Ph+ ALL treated with SPRYCEL at the recommended dose (n=304), grade 3/4 fluid retention was reported in 8% of patients, including grade 3/4 pleural effusion reported in 7% of patients. In pediatric patients with chronic phase CML cases of Grade 1 or 2 fluid retention were reported in 10.3% of patients.

Patients who develop symptoms of pleural effusion or other fluid retention, such as new or worsened dyspnea on exertion or at rest, pleuritic chest pain, or dry cough should be evaluated promptly with a chest x-ray or additional diagnostic imaging as appropriate
Fluid retention events were typically managed by supportive care measures that may include diuretics or short courses of steroids
Severe pleural effusion may require thoracentesis and oxygen therapy
Consider dose reduction or treatment interruption
Cardiovascular Events

SPRYCEL can cause cardiac dysfunction. After 5 years of follow-up in the randomized newly diagnosed chronic phase CML trial in adults (n=258), the following cardiac adverse reactions occurred:

Cardiac ischemic events (3.9% dasatinib vs 1.6% imatinib), cardiac related fluid retention (8.5% dasatinib vs 3.9% imatinib), and conduction system abnormalities, most commonly arrhythmia and palpitations (7.0% dasatinib vs 5.0% imatinib). Two cases (0.8%) of peripheral arterial occlusive disease occurred with imatinib and 2 (0.8%) transient ischemic attacks occurred with dasatinib
Monitor patients for signs or symptoms consistent with cardiac dysfunction and treat appropriately.

Pulmonary Arterial Hypertension (PAH)

SPRYCEL may increase the risk of developing PAH in adult and pediatric patients, which may occur any time after initiation, including after more than 1 year of treatment. Manifestations include dyspnea, fatigue, hypoxia, and fluid retention. PAH may be reversible on discontinuation of SPRYCEL.

Evaluate patients for signs and symptoms of underlying cardiopulmonary disease prior to initiating SPRYCEL and during treatment. If PAH is confirmed, SPRYCEL should be permanently discontinued
QT Prolongation

SPRYCEL may increase the risk of prolongation of QTc in patients including those with hypokalemia or hypomagnesemia, patients with congenital long QT syndrome, patients taking antiarrhythmic medicines or other medicinal products that lead to QT prolongation, and cumulative high-dose anthracycline therapy

Correct hypokalemia or hypomagnesemia prior to and during SPRYCEL administration
Severe Dermatologic Reactions

Cases of severe mucocutaneous dermatologic reactions, including Stevens-Johnson syndrome and erythema multiforme, have been reported in patients treated with SPRYCEL.

Discontinue permanently in patients who experience a severe mucocutaneous reaction during treatment if no other etiology can be identified
Tumor Lysis Syndrome (TLS)

TLS has been reported in patients with resistance to prior imatinib therapy, primarily in advanced phase disease.

Due to potential for TLS, maintain adequate hydration, correct uric acid levels prior to initiating therapy with SPRYCEL, and monitor electrolyte levels
Patients with advanced stage disease and/or high tumor burden may be at increased risk and should be monitored more frequently
Embryo-Fetal Toxicity

Based on limited human data, SPRYCEL can cause fetal harm when administered to a pregnant woman. Hydrops fetalis, fetal leukopenia and fetal thrombocytopenia have been reported with maternal exposure to SPRYCEL. Transplacental transfer of dasatinib has been measured in fetal plasma and amniotic fluid at concentrations comparable to those in maternal plasma.

Advise females of reproductive potential to avoid pregnancy, which may include the use of effective contraception, during treatment with SPRYCEL and for 30 days after the final dose
Effects on Growth and Development in Pediatric Patients

In pediatric trials of SPRYCEL in chronic phase CML after at least 2 years of treatment, adverse reactions associated with bone growth and development were reported in 5 (5.2%) patients, one of which was severe in intensity (Growth Retardation Grade 3). These 5 cases included cases of epiphyses delayed fusion, osteopenia, growth retardation, and gynecomastia. Of these 5 cases, 1 case of osteopenia and 1 case of gynecomastia resolved during treatment.

Lactation

No data are available regarding the presence of dasatinib in human milk, the effects of the drug on the breastfed child or the effects of the drug on milk production. However, dasatinib is present in the milk of lactating rats.

Because of the potential for serious adverse reactions in nursing children from SPRYCEL, breastfeeding is not recommended during treatment with SPRYCEL and for 2 weeks after the final dose
Drug Interactions

Strong CYP3A4 inhibitors: The coadministration with strong CYP3A inhibitors may increase dasatinib concentrations. Increased dasatinib concentrations may increase the risk of toxicity. Avoid concomitant use of strong CYP3A4 inhibitors. If concomitant administration of a strong CYP3A4 inhibitor cannot be avoided, consider a SPRYCEL dose reduction
Grapefruit juice may increase plasma concentrations of SPRYCEL and should be avoided
Strong CYP3A4 inducers: The coadministration of SPRYCEL with strong CYP3A inducers may decrease dasatinib concentrations. Decreased dasatinib concentrations may reduce efficacy. Consider alternative drugs with less enzyme induction potential. If concomitant administration of a strong CYP3A4 inducer cannot be avoided, consider a SPRYCEL dose increase
St. John’s wort may decrease plasma concentrations of SPRYCEL and should be avoided
Gastric Acid Reducing Agents: The coadministration of SPRYCEL with a gastric acid reducing agent may decrease the concentrations of dasatinib. Decreased dasatinib concentrations may reduce efficacy.

Do not administer H2 antagonists or proton pump inhibitors with SPRYCEL. Consider the use of antacids in place of H2 antagonists or proton pump inhibitors. Administer the antacid at least 2 hours prior to or 2 hours after the dose of SPRYCEL. Avoid simultaneous administration of SPRYCEL with antacids.
Adverse Reactions

The safety data reflects exposure to SPRYCEL at all doses tested in clinical studies (n=2809) including 324 adult patients with newly diagnosed chronic phase CML, 2388 adult patients with imatinib resistant or intolerant chronic or advanced phase CML or Ph+ ALL, and 97 pediatric patients with chronic phase CML.

The median duration of therapy in a total of 2712 SPRYCEL-treated adult patients was 19.2 months (range 0–93.2 months). Median duration of therapy in:

1618 adult patients with chronic phase CML was 29 months (range 0–92.9 months)
Median duration for 324 adult patients in the newly diagnosed chronic phase CML trial was approximately 60 months
1094 adult patients with advanced phase CML or Ph+ ALL was 6.2 months (range 0–93.2 months)
In two non-randomized trials in 97 pediatric patients with chronic phase CML (51 patients newly diagnosed and 46 patients resistant or intolerant to previous treatment with imatinib), the median duration of therapy was 51.1 months (range 1.9 to 99.6 months).

In the newly diagnosed adult chronic phase CML trial, after a minimum of 60 months of follow-up, the cumulative discontinuation rate for 258 patients was 39%.

In the overall population of 2712 adult SPRYCEL-treated patients, 88% of patients experienced adverse reactions at some time and 19% experienced adverse reactions leading to treatment discontinuation.

Among the 1618 adult SPRYCEL-treated patients with chronic phase CML, drug-related adverse reactions leading to discontinuation were reported in 329 (20.3%) patients.

In the adult newly diagnosed chronic phase CML trial, drug was discontinued for adverse reactions in 16% of SPRYCEL-treated patients with a minimum of 60 months of follow-up
Among the 1094 SPRYCEL-treated patients with advanced phase CML or Ph+ ALL, drug-related adverse reactions leading to discontinuation were reported in 191 (17.5%) patients.

Among the 97 pediatric subjects, drug-related adverse reactions leading to discontinuation were reported in 1 patient (1%).

Patients ≥65 years are more likely to experience the commonly reported adverse reactions of fatigue, pleural effusion, diarrhea, dyspnea, cough, lower gastrointestinal hemorrhage, and appetite disturbance, and more likely to experience the less frequently reported adverse reactions of abdominal distention, dizziness, pericardial effusion, congestive heart failure, hypertension, pulmonary edema and weight decrease, and should be monitored closely.

In adult newly diagnosed chronic phase CML patients:
Drug-related serious adverse reactions (SARs) were reported for 16.7% of patients. Serious adverse reactions reported in ≥5% of patients included pleural effusion (5%)
Grade 3/4 laboratory abnormalities included neutropenia (29%), thrombocytopenia (22%), anemia (13%), hypophosphatemia (7%), hypocalcemia (4%), elevated bilirubin (1%), and elevated creatinine (1%)
In adult patients resistant or intolerant to prior imatinib therapy:
Drug-related SARs were reported for 26.1% of SPRYCEL-treated patients treated at the recommended dose of 100 mg once daily in the randomized dose-optimization trial of patients with chronic phase CML resistant or intolerant to prior imatinib therapy. Serious adverse reactions reported in ≥5% of patients included pleural effusion (10%)
Grade 3/4 hematologic laboratory abnormalities in chronic phase CML patients resistant or intolerant to prior imatinib therapy who received SPRYCEL 100 mg once daily with a minimum follow up of 60 months included neutropenia (36%), thrombocytopenia (24%), and anemia (13%). Other grade 3/4 laboratory abnormalities included: hypophosphatemia (10%), and hypokalemia (2%)
Among chronic phase CML patients with resistance or intolerance to prior imatinib therapy, cumulative grade 3/4 cytopenias were similar at 2 and 5 years including: neutropenia (36% vs 36%), thrombocytopenia (23% vs 24%), and anemia (13% vs 13%)
Grade 3/4 elevations of transaminases or bilirubin and Grade 3/4 hypocalcemia, hypokalemia, and hypophosphatemia were reported in patients with all phases of CML
Elevations in transaminases or bilirubin were usually managed with dose reduction or interruption
Patients developing Grade 3/4 hypocalcemia during the course of SPRYCEL therapy often had recovery with oral calcium supplementation
In pediatric subjects with Ph+ CML in chronic phase
Drug-related SARs were reported for 14.4% of pediatric patients
In the pediatric studies, the rates of laboratory abnormalities were consistent with the known profile for laboratory parameters in adults
Most common adverse reactions (≥15%) in patients included myelosuppression, fluid retention events, diarrhea, headache, skin rash, hemorrhage, dyspnea, fatigue, nausea, and musculoskeletal pain

C4XD aims to apply its proprietary 4D shape-based chemistry technology (Conformetrix) to discover drug candidates directed against these high value, novel, synthetic lethality targets and out-license them to clinical development partners. This discovery partnership bolsters C4XD’s oncology pipeline, a high priority therapeutic area for the company.

The therapeutic concept of harnessing synthetic lethality in cancer with tumour-specific mutations has been demonstrated with the recent approval of the poly(ADP-ribose) polymerase (PARP) inhibitors Lynparza Zejula and Rubraca. These drugs are effective in indications that are poorly served by immunotherapy drugs, such as checkpoint inhibitors, and have become an established treatment in ovarian cancer. They work by targeting a specific DNA repair pathway that cancer cells, with mutations such as BRCA, become over-reliant on. Inhibiting this critical DNA repair pathway causes the tumour cells to self-destruct, resulting in the terminology ‘synthetic lethality’. The pharmaceutical industry is now rushing to fill its clinical pipelines with investigational drugs, identified by empirical research, that might produce similar efficacy in cancers where PARP inhibitors are not effective.

However, recent advancements in the gene-editing tool, CRISPR-Cas9, has enabled systematic ‘functional genomic’ screening to identify novel synthetic lethal genes in cancer cells with specific mutations. Horizon has utilised its target discovery platform to conduct high quality CRISPR gene knock-out studies across multiple cancer cell lines, screening around ~3000 genes suitable as the basis for small molecule drug targets. This cutting-edge approach has identified a shortlist of ~20 novel, high value synthetic lethal genes following a secondary screen to further validate them as targets. The partnership has been established to complete the target validation package for these novel targets, leading to the initiation of drug discovery programmes by C4XD should it exercise its options on a target-by-target basis. C4XD will provide the funding for the work plan and Horizon will receive a share of all future revenues C4XD receives should any drug discovery programmes emerging from the partnership be out-licensed for clinical development.

Dr Craig Fox, Chief Scientific Officer of C4XD, said: "PARP inhibitors are transforming the treatment of ovarian cancer, particularly in patients with BRCA mutations and so identifying the next generation of synthetic lethality drug targets is a key priority to develop new therapies for cancers patients who are not responsive to current treatments. This partnership with Horizon gives C4XD access to a comprehensive proprietary CRISPR screening dataset that has selected the most promising novel drug targets in colon and lung cancer. We look forward to working with the highly experienced team at Horizon to complete the target validation package for these novel genes and initiate drug discovery programmes to generate high value pre-clinical licensable assets for partnering."

Dr Jon Moore, Horizon’s Chief Scientific Officer added: "Drugging the cancer genome now requires new synthetic lethal therapies that can exploit the vulnerabilities in patient’s tumours that are created by mutations in undruggable cancer driver genes. Horizon’s internal research program has used powerful CRISPR technology to open a new window into how cancer cells are wired and has identified a cohort of novel targets. We are delighted to have secured this collaboration with C4X Discovery, which applies a powerful drug discovery engine to the first-in-class opportunities for transformational medicines represented by the targets Horizon has found and allows Horizon to share in the upside."
