"The outcome of this phase 2 study with anetumab ravtansine in recurrent malignant pleural mesothelioma is disappointing, in particular for the patients suffering from this serious and extremely difficult to treat disease", said Dr. Markus Enzelberger, Interim Chief Scientific Officer of MorphoSys AG. "Nevertheless, Bayer remains committed to further evaluating the potential of this compound across multiple tumor types with significant unmet medical need. We are proud of our long-standing relationship with Bayer, and we look forward to further updates about the development program with anetumab ravtansine going forward."

The phase 2 clinical trial is a randomized, open-label, active-controlled, multicenter superiority study evaluating the safety and efficacy of anetumab ravtansine as second-line treatment in 248 patients with advanced or metastatic mesothelin-positive malignant pleural mesothelioma whose disease had progressed after treatment with first-line platinum/pemetrexed-based chemotherapy.

Bayer reported further that anetumab ravtansine is currently being investigated, as monotherapy and in combination, in additional studies, including a Phase Ib multi-indication study in six different types of advanced solid tumors, as well as a Phase Ib combination-study in patients with recurrent platinum-resistant ovarian cancer. According to Bayer, based on the available data, Bayer remains committed to further evaluating the utility and safety of anetumab ravtansine across multiple tumor types with significant unmet medical need. Bayer further announced that, in the trial reported, the safety and tolerability of anetumab ravtansine were consistent with earlier clinical findings and that detailed study results are expected to be presented at an upcoming medical meeting.

Further detailed information about mesothelioma and the clinical study can be found in a press release issued by Bayer or at clinicaltrials.gov.

There is no change to MorphoSys’s financial guidance for Fiscal Year 2017.

About anetumab ravtansine
Anetumab ravtansine is an antibody-drug conjugate (ADC) that specifically targets mesothelin, a surface marker protein overexpressed in many cancers. After binding to mesothelin, anetumab ravtansine is taken up inside the tumor cells, where degrading enzymes release cytotoxic DM4, a maytansinoid tubulin inhibitor, which induces cell cycle arrest and apoptosis in dividing cells. Anetumab ravtansine comprises an antibody made using MorphoSys’s HuCAL technology.

Syros Publishes Foundational Data Supporting Ongoing Phase 2 Clinical Trial of SY-1425 for Genomically Defined AML and MDS Patients

On July 21, 2017 Syros Pharmaceuticals (NASDAQ: SYRS) reported that data providing the foundation of its clinical development strategy for SY-1425, its first-in-class selective retinoic acid receptor alpha (RARα) agonist currently in a Phase 2 clinical trial in genomically defined subsets of patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS), were published online in Cancer Discovery, a peer-reviewed journal of the American Association of Cancer Research. Syros is on track to present initial data from the Phase 2 clinical trial this fall (Press release, Syros Pharmaceuticals, JUL 21, 2017, View Source [SID1234519876]).

The publication highlights Syros’ discovery of a subset of AML patients with a super-enhancer associated with the RARA gene, which was shown in preclinical studies to be predictive of response to SY-1425. Syros also found a subset of MDS patients with high expression of the RARA gene and demonstrated in ex vivo studies that RARA-high MDS had a similar response to SY-1425 as that seen in AML driven by the RARA super-enhancer.

"The publication of our work in Cancer Discovery is a demonstration of our pioneering approach for analyzing non-coding regulatory regions of the genome to identify disease-driving genes with the goal of developing new medicines that make a meaningful difference for patients," said Eric Olson, Ph.D., Chief Scientific Officer of Syros. "Although genetic mutations associated with AML and MDS in protein-coding regions of the genome are well known, there are limited targeted therapy options in these diseases and there remains a high unmet need. Our investigation of the regulatory genome adds a new dimension to the understanding of AML and MDS disease biology that offers the potential to address these underserved patient populations and improve their prognosis and treatment."

In collaboration with the Majeti lab at Stanford University School of Medicine, Syros used its gene control platform to analyze 66 AML patients’ tumor samples and identified six distinct patient subsets based on super-enhancer profiles, including one enriched for a super-enhancer associated with the RARA gene. The data show that:

· Super-enhancer profiles were strongly associated with survival outcomes, often independent of known genetic mutations in AML.

· The RARA super-enhancer was associated with high expression of the RARA gene, which codes for a transcription factor targeted by SY-1425.

· The RARA super-enhancer was predictive of response to SY-1425. In AML cells with high RARA expression, SY-1425 reduced proliferation and promoted differentiation. Moreover, SY-1425 decreased tumor burden and prolonged survival in patient-derived xenograft (PDX) models of AML with high RARA expression, while no effect was found on AML cells or PDX models with low RARA expression. Notably, ATRA, a less potent and non-selective retinoid, produced no survival benefit in PDX models with high RARA expression.

· SY-1425 induced profound transcriptional changes promoting cell differentiation in AML cells with high RARA expression but little to no transcriptional changes in AML cells with low RARA expression.

· DHRS3 was the most strongly and rapidly induced gene in response to treatment with SY-1425, leading to the identification of DHRS3 induction as a pharmacodynamic marker for use in the ongoing Phase 2 clinical trial as an early indicator of whether SY-1425 is affecting the targeted biology in defined subsets of AML and MDS patients.

· SY-1425 induced transcriptional and epigenomic changes in AML cells with high RARA expression similar to those seen in acute promyelocytic leukemia (APL) cells treated with SY-1425. SY-1425 is approved in Japan as Amnolake (tamibarotene) to treat relapsed or refractory APL, a form of AML that is driven by fusions of the RARA gene, and has a well-established safety and efficacy profile in those patients.

The Phase 2 clinical trial of SY-1425 is assessing the safety and efficacy of SY-1425 as a single agent in four AML and MDS patient populations, as well as in combination with azacitidine, a standard-of-care therapy, in newly diagnosed AML patients who are not suitable candidates for standard chemotherapy. All patients in the trial are prospectively selected using biomarkers for high expression of RARA or IRF8, which are genes associated with the RARA pathway. Additional details about the trial can be found using the identifier NCT02807558 at www.clinicaltrials.gov

European Medicines Agency’s CHMP Recommends Approval for Merck’s KEYTRUDA® (pembrolizumab) for the Treatment of Certain Patients with Locally Advanced or Metastatic Urothelial Carcinoma, a Type of Bladder Cancer

On July 21, 2017 Merck (NYSE:MRK), known as MSD outside the United States and Canada, reported that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion recommending approval of KEYTRUDA (pembrolizumab), the company’s anti-PD-1 therapy, for the treatment of certain patients with locally advanced or metastatic urothelial carcinoma, a type of bladder cancer (Press release, Merck & Co, JUL 21, 2017, View Source [SID1234519854]). Specifically, KEYTRUDA is recommended for the treatment of locally advanced or metastatic urothelial carcinoma in adult patients who have received prior platinum-containing chemotherapy, as well as adult patients who are not eligible for cisplatin-containing chemotherapy. The recommendation will now be reviewed by the European Commission for marketing authorization in the European Union. A final decision is expected in the third quarter of 2017.

"There is significant need for new options that address the treatment gaps for patients in Europe with locally advanced or metastatic urothelial carcinoma, especially for those who have failed on prior platinum treatment or are ineligible for cisplatin-containing chemotherapy," said Dr. Roger Dansey, senior vice president and therapeutic area head, oncology late-stage development, Merck Research Laboratories. "We are pleased that the CHMP has provided a positive opinion for KEYTRUDA in these two patient populations and look forward to working with the European Commission to bring forward this new option for patients in need."

The positive opinion is based on data from the KEYNOTE-045 and KEYNOTE-052 trials. KEYNOTE-045 is a phase 3, randomized study investigating KEYTRUDA (pembrolizumab) compared to investigator-choice chemotherapy (paclitaxel, docetaxel, vinflunine) in patients with locally advanced or metastatic urothelial carcinoma that has recurred or progressed on or after platinum-containing chemotherapy. KEYNOTE-052 is a phase 2, open-label study investigating KEYTRUDA in treatment-naïve patients with locally advanced or metastatic urothelial carcinoma who are ineligible for cisplatin-containing therapy.

The KEYTRUDA clinical development program includes more than 30 tumor types in more than 500 clinical trials, including more than 300 trials that combine KEYTRUDA with other cancer treatments. Currently, Merck has the largest immuno-oncology clinical development program in bladder cancer, with 29 trials underway involving KEYTRUDA as monotherapy and in combination, including four registration-enabling studies.

About Bladder Cancer
Bladder cancer begins when cells in the urinary bladder start to grow uncontrollably. As more cancer cells develop, they can form a tumor and spread to other areas of the body. Urothelial carcinoma, the most common type of bladder cancer, starts in the urothelial cells that line the inside of the bladder. In 2012, approximately 430,000 people worldwide were diagnosed with bladder cancer and 165,000 died from the disease. The incidence of bladder cancer is elevated in North America, Europe, North Africa, the Middle East, Australia and New Zealand.

About KEYTRUDA (pembrolizumab) Injection
KEYTRUDA is an anti-PD-1 therapy that works by increasing the ability of the body’s immune system to help detect and fight tumor cells. KEYTRUDA is a humanized monoclonal antibody that blocks the interaction between PD-1 and its ligands, PD-L1 and PD-L2, thereby activating T lymphocytes which may affect both tumor cells and healthy cells.
Studies of KEYTRUDA – from the largest immuno-oncology program in the industry with more than 500 trials – include a wide variety of cancers and treatment settings. The KEYTRUDA clinical program seeks to understand factors that predict a patient’s likelihood of benefitting from treatment with KEYTRUDA, including the exploration of several different biomarkers across a broad range of tumors.

KEYTRUDA (pembrolizumab) is administered as an intravenous infusion over 30 minutes every three weeks for the approved indications. KEYTRUDA for injection is supplied in a 100 mg single-dose vial in the U.S.

"We welcome the CHMP’s recommendation, as there are currently no approved treatments in Europe for this type of skin cancer, which can be devastating for patients and their families," said Luciano Rossetti, M.D., Executive Vice President, Global Head of Research & Development at the biopharma business of Merck KGaA, Darmstadt, Germany. "This is an important step towards making avelumab available to patients and we look forward to the European Commission’s decision later this year."

"Metastatic Merkel cell carcinoma is a devastating disease and patients in Europe currently have very few treatment options," said Chris Boshoff, M.D., PhD, Senior Vice President and Head of Immuno-Oncology, Early Development, Translational Oncology, Pfizer Global Product Development. "This milestone further demonstrates our commitment to tackle hard-to-treat cancers as we continue to explore the potential of avelumab in other tumors."

The CHMP positive opinion is based on data from JAVELIN Merkel 200, an international, multicenter, single-arm, open-label, Phase II study split into two parts:

· Part A included 88 patients with mMCC whose disease had progressed after at least one chemotherapy treatment, with 59% of patients reported to have had one prior anti-cancer therapy for mMCC and 41% had two or more prior therapies. Data submitted included a minimum of 18 months of follow-up.

· Part B, at the time of the data cut-off, included 39 patients with histologically confirmed mMCC who were treatment-naïve to systemic therapy in metastatic setting, 29 of whom had at least 13 weeks of follow-up.

Enrolment in Part B of the study is ongoing and is planned to include 112 treatment-naïve patients.

The human anti-PD-L1 antibody, avelumab, previously received Orphan Drug Designation (ODD) from the EC for MCC. To qualify for ODD in the EU, a medicine must be intended for the treatment, prevention or diagnosis of a disease that is life-threatening or chronically debilitating, and has a prevalence in the EU of not more than 5 in 10,000 people.

The US Food and Drug Administration (FDA) granted accelerated approval for avelumab in March 2017 for the treatment of mMCC in adults and pediatric patients 12 years and older; and in May 2017 for the treatment of patients with locally advanced or metastatic urothelial carcinoma who have disease progression during or following platinum-containing chemotherapy therapy, or who have disease progression within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy.[1] These indications were granted under accelerated approval based on tumor response rate and duration of response data/criteria. Continued approval for these indications may be contingent upon verification and description of clinical benefit in confirmatory trials.

The clinical development program for avelumab, known as JAVELIN, involves at least 30 clinical programs and more than 6,000 patients evaluated across more than 15 different tumor types. In addition to mMCC, these cancers include breast, gastric/gastro-esophageal junction, head and neck, Hodgkin’s lymphoma, melanoma, mesothelioma, non-small cell lung, ovarian, renal cell carcinoma and urothelial carcinoma.

*Avelumab is not approved for any indication in any market outside the US. BAVENCIO is the proprietary name submitted to EMA for the investigational medicine avelumab.

About Metastatic Merkel Cell Carcinoma
Metastatic MCC is a rare and aggressive disease in which cancer cells form in the top layer of the skin, close to nerve endings.[2],[3] MCC, which is also known as neuroendocrine carcinoma of the skin or trabecular cancer, often starts in those areas of skin that are most often exposed to the sun, including the head and neck, and arms.[2],[4] Risk factors for MCC include sun exposure and infection with Merkel cell polyomavirus. Caucasian males older than 50 are at increased risk.[2],[4] MCC is a highly immunogenic cancer, meaning that those with a weak immune system (i.e., solid organ transplant recipients, people with HIV/AIDS and people with other cancers, such as chronic lymphocytic leukemia) are also at a higher risk.[2],[4] MCC is often misdiagnosed for other skin cancers and grows at an exponential rate on chronically sun-damaged skin.[4]-[6] Current treatment options for MCC in Europe include surgery, radiation and chemotherapy.[3] Treatment for metastatic or Stage IV MCC is generally palliative.[3]

About JAVELIN Merkel 200
The efficacy and safety of avelumab was demonstrated in the JAVELIN Merkel 200 trial, an international, multicenter, single-arm, open-label, Phase II study split into two parts:

· Part A was conducted in 88 patients with histologically confirmed mMCC whose disease had progressed on or after chemotherapy administered for distant metastatic disease, with life expectancy of more than 3 months. Overall, in Part A, 59% of patients were reported to have had one prior anti-cancer therapy for mMCC and 41% had two or more prior therapies. Data submitted included a minimum of 18 months follow-up. The major efficacy outcome measures for Part A were confirmed best overall response (BOR) and duration of response (DOR), according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1, as assessed by a blinded independent endpoint review committee (IERC); secondary efficacy outcome measures included duration of response (DOR), and progression-free survival (PFS).

· Part B, at the time of the data cut-off, included 39 patients with histologically confirmed mMCC who were treatment-naïve to systemic therapy in the metastatic setting, 29 of whom had at least 13 weeks of follow-up. Enrolment in Part B of the study is ongoing and is planned to include 112 treatment-naïve patients. The major efficacy outcome measure is durable response, defined as objective response (complete response [CR] or partial response [PR]) with a duration of at least 6 months; secondary outcome measures include BOR, DOR, progression-free survival (PFS) and overall survival (OS).

The trial excluded patients with active or a history of central nervous system (CNS) metastasis, active or a history of autoimmune disease, a history of other malignancies within the last 5 years, organ transplant, and conditions requiring therapeutic immune suppression or active infection with HIV, or hepatitis B or C. Patients received avelumab 10 mg/kg as an intravenous infusion over 60 minutes every 2 weeks until disease progression or unacceptable toxicity.

About Avelumab
Avelumab is a human antibody specific for a protein called PD-L1, or programmed death ligand-1. Avelumab is designed to potentially engage both the adaptive and innate immune systems. By binding to PD-L1, avelumab is thought to prevent tumor cells from using PD-L1 for protection against white blood cells, such as T cells, exposing them to anti-tumor responses. Avelumab has been shown to induce antibody-dependent cell-mediated cytotoxicity (ADCC) in vitro. In November 2014, Merck KGaA, Darmstadt, Germany, and Pfizer announced a strategic alliance to co-develop and co-commercialize avelumab.

Indications
The US Food and Drug Administration (FDA) granted accelerated approval for avelumab (BAVENCIO) for the treatment of (i) mMCC in adults and pediatric patients 12 years and older and (ii) patients with locally advanced or metastatic UC who have disease progression during or following platinum-containing chemotherapy, or who have disease progression within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy. These indications were approved under accelerated approval based on tumor response rate and duration of response. Continued approval for these indications may be contingent upon verification and description of clinical benefit in confirmatory trials.

Administer corticosteroids for Grade 2 or greater nephritis. Withhold BAVENCIO for moderate (Grade 2) or severe (Grade 3) nephritis until resolution to Grade 1 or lower. Permanently discontinue BAVENCIO for life-threatening (Grade 4) nephritis. Immune-mediated nephritis occurred in 0.1% (1/1738) of patients.

BAVENCIO can result in other severe and fatal immune-mediated adverse reactions involving any organ system during treatment or after treatment discontinuation. For suspected immune-mediated adverse reactions, evaluate to confirm or rule out an immune-mediated adverse reaction and to exclude other causes. Depending on the severity of the adverse reaction, withhold or permanently discontinue BAVENCIO, administer high-dose corticosteroids, and initiate hormone replacement therapy if appropriate. Resume BAVENCIO when the immune-mediated adverse reaction remains at Grade 1 or lower following a corticosteroid taper. Permanently discontinue BAVENCIO for any severe (Grade 3) immune-mediated adverse reaction that recurs and for any life-threatening (Grade 4) immune-mediated adverse reaction. The following clinically significant immune-mediated adverse reactions occurred in less than 1% of 1738 patients treated with BAVENCIO: myocarditis with fatal cases, myositis, psoriasis, arthritis, exfoliative dermatitis, erythema multiforme, pemphigoid, hypopituitarism, uveitis, Guillain-Barré syndrome, and systemic inflammatory response.

BAVENCIO can cause severe (Grade 3) or life-threatening (Grade 4) infusion-related reactions. Patients should be premedicated with an antihistamine and acetaminophen prior to the first 4 infusions and for subsequent doses based upon clinical judgment and presence/severity of prior infusion reactions. Monitor patients for signs and symptoms of infusion-related reactions, including pyrexia, chills, flushing, hypotension, dyspnea, wheezing, back pain, abdominal pain, and urticaria. Interrupt or slow the rate of infusion for mild (Grade 1) or moderate (Grade 2) infusion-related reactions. Permanently discontinue BAVENCIO for severe (Grade 3) or life-threatening (Grade 4) infusion-related reactions. Infusion-related reactions occurred in 25% (439/1738) of patients, including three (0.2%) patients with Grade 4 and nine (0.5%) with Grade 3.

BAVENCIO can cause fetal harm when administered to a pregnant woman. Advise patients of the potential risk to a fetus including the risk of fetal death. Advise females of childbearing potential to use effective contraception during treatment with BAVENCIO and for at least 1 month after the last dose of BAVENCIO. It is not known whether BAVENCIO is excreted in human milk. Advise a lactating woman not to breastfeed during treatment and for at least 1 month after the last dose of BAVENCIO due to the potential for serious adverse reactions in breastfed infants.
The most common adverse reactions (all grades, ≥ 20%) in patients with metastatic Merkel cell carcinoma (MCC) were fatigue (50%), musculoskeletal pain (32%), diarrhea (23%), nausea (22%), infusion-related reaction (22%), rash (22%), decreased appetite (20%), and peripheral edema (20%).

Selected treatment-emergent laboratory abnormalities (all grades, ≥ 20%) in patients with metastatic MCC were lymphopenia (49%), anemia (35%), increased aspartate aminotransferase (34%), thrombocytopenia (27%), and increased alanine aminotransferase (20%).

The most common adverse reactions (all grades, ≥ 20%) in patients with locally advanced or metastatic urothelial cancer (UC) were fatigue (41%), infusion-related reaction (30%), musculoskeletal pain (25%), nausea (24%), decreased appetite/hypophagia (21%) and urinary tract infection (21%).

Selected laboratory abnormalities (grades 3-4, ≥ 3%) in patients with locally advanced or metastatic UC were hyponatremia (16%), gamma-glutamyltransferase increased (12%), lymphopenia (11%), hyperglycemia (9%), increased alkaline phosphatase (7%), anemia (6%), increased lipase (6%), hyperkalemia (3%), and increased aspartate aminotransferase (3%).
