FDA Grants Orphan Drug Designation to Merrimack Pharmaceuticals’ MM-141 for the Treatment of Pancreatic Cancer

On November 5, 2014 Merrimack Pharmaceuticals reported that the U.S. Food and Drug Administration (FDA) has granted orphan drug designation to their investigational drug candidate MM-141 for the treatment of pancreatic cancer (Press release Merrimack, NOV 5, 2014, View Source [SID:1234500923]). MM-141 is a tetravalent bispecific antibody designed to block tumor survival signals by targeting receptor complexes containing IGF-1R and ErbB3 (HER3). The IGF-1R and HER3 complexes both activate a major cellular signaling pathway that allows tumor cells to grow and develop resistance to therapies.

"Receiving orphan drug designation for MM-141 is an important regulatory advancement in the development of our clinical program," said Ulrik Nielsen, Ph.D., Chief Scientific Officer and Co-Founder of Merrimack. "Pancreatic cancer is an aggressive and devastating disease, with a five year survival rate of 6% and a low early detection rate. Merrimack is dedicated to changing the landscape of this disease for patients across all lines of therapy. We look forward to advancing the clinical development of MM-141 as we believe that it has the potential to significantly inhibit tumor survival signaling and address pathways of therapeutic resistance in this indication."

The FDA’s Office of Orphan Products Development (OOPD) designates orphan status to drugs and biologics intended for the safe and effective treatment, diagnosis or prevention of rare diseases/disorders that affect fewer than 200,000 people in the United States. This orphan drug designation will potentially provide Merrimack Pharmaceuticals with seven-year marketing exclusivity for MM-141 and other benefits if the drug is approved by the FDA.

MM-141 is Merrimack’s sixth oncology candidate to enter clinical development and is currently being tested in a Phase 1 dose-escalation clinical study. A Phase 2 study testing MM-141 in combination with nab-paclitaxel and gemcitabine in front line pancreatic cancer is expected to start in 2015.

AstraZeneca and Pharmacyclics enter clinical trial collaborations in oncology

On November 4, 2014 AstraZeneca and Pharmacyclics reported that they have entered into clinical trial collaborations to evaluate novel combination therapies targeting solid tumours and a number of haematological cancers (Press release AstraZeneca, NOV 4, 2014, View Source;astrazeneca-and-pharmacyclics-enter-clinical-trial-collaborations-oncology [SID:1234500963]).

The first collaboration, focusing on solid tumours, will evaluate the efficacy and safety of IMBRUVICA (ibrutinib), Pharmacyclics’ oral Bruton’s tyrosine kinase inhibitor in combination with AstraZeneca’s anti-PD-L1 antibody, MEDI4736.

The second collaboration will focus on haematological cancers and will explore separate combinations of two different AstraZeneca investigational PI3 kinase pathway inhibitors with IMBRUVICA, for the treatment of patients with relapsed or refractory diffuse large B-cell lymphomas. Preclinical evidence suggests that the combination of IMBRUVICA with these investigational medicines may enhance their effects.

Under the terms of the agreements, AstraZeneca and Pharmacyclics will collaborate on a non-exclusive basis and multiple Phase I and Phase IIa studies may be considered and conducted. The studies focused on solid tumours will be led by Pharmacyclics, while AstraZeneca will lead those exploring haematological cancers. The Phase I element of each study is expected to establish a recommended safe and tolerable dose and schedule for the combination and the Phase IIa element will assess its safety and efficacy in an expanded patient population. The financial terms of the agreement have not been disclosed. The results of the clinical studies will be used to determine whether further clinical development of the different combinations is warranted.

Susan Galbraith, Head of AstraZeneca’s Oncology Innovative Medicines Unit said: "There is a clear and significant unmet need in the treatment of haematological malignancies, an area of increasing focus for AstraZeneca. Our partnership with Pharmacyclics will allow us to explore new and potentially potent treatment combinations, which could have a positive impact on patient outcomes."

"We are optimistic that combining our oral once-per-day IMBRUVICA with other agents has the potential to enhance efficacy and duration across the landscape of haematological cancers," said Bob Duggan, Chairman & CEO, Pharmacyclics. "In addition, we are extremely interested in the potential for IMBRUVICA in combination with an anti-PD-L1 antibody to improve the treatment of solid tumours in patients who need better therapeutic options."

Third Quarter Financial Results and 2014 Revenue Guidance

Corcept recognized $7.3 million in net revenue for the third quarter of 2014 compared to $5.9 million in the second quarter, an increase of 24 percent. The company’s net loss in the third quarter on a GAAP basis was $6.0 million, or $0.06 per share, compared to a net loss of $7.6 million, or $0.07 per share, in the second quarter.
The company’s net loss on a GAAP basis included significant non-cash items of $2.1 million in the third quarter and $2.2 million in the second quarter. Excluding these items, the company’s net loss on a non-GAAP basis was $3.9 million, or $0.04 per share, for the third quarter of 2014 and $5.4 million or $0.05 per share, for the second quarter.
As of September 30, 2014, the company held cash and cash equivalents of $26.8 million.
The company revised the range of its 2014 revenue guidance to $25-27 million.
"Our Cushing’s syndrome commercial business continues to grow and now generates cash to fund an increasing portion of our research and development activities," said Joseph K. Belanoff, M.D., Corcept’s Chief Executive Officer. "While there is a group of endocrinologists who have seen Korlym’s benefits and have become repeat prescribers, there are many physicians who have not yet written their first prescription. These physicians represent the potential for better treatment for more patients and significant future revenues."

Clinical Pipeline Progress

"We expect to have identified tolerable doses of Korlym and Halaven (eribulin) in our triple-negative breast cancer study by year-end, when the study’s efficacy phase is scheduled to begin. In September, we began dosing patients in our Phase 1 trial of CORT 125134. We will advance additional selective 1 glucocorticoid receptor (GR) antagonists into the clinic next year. GR antagonism is an exciting area of research that will generate interesting data in 2015, both from our own studies and from those being undertaken by our academic collaborators."

About Korlym

Korlym competitively blocks the glucocorticoid receptor type II (GR), one of the two receptors to which cortisol normally binds, thereby inhibiting the effects of excess cortisol in patients with Cushing’s syndrome. In April 2012, Corcept made Korlym available as a once-daily oral treatment of hyperglycemia secondary to endogenous Cushing’s syndrome in adult patients with glucose intolerance or diabetes mellitus type 2 who have failed surgery or are not candidates for surgery. Korlym was the first FDA-approved treatment for that illness and the FDA has designated it as an Orphan Drug for that indication.

About Cushing’s Syndrome

Endogenous Cushing’s syndrome is caused by prolonged exposure of the body’s tissues to high levels of the hormone cortisol and is generated by tumors that produce cortisol or ACTH. Cushing’s syndrome is an orphan indication that most commonly affects adults aged 20-50. An estimated 10-15 of every one million people are newly diagnosed with this syndrome each year, resulting in over 3,000 new patients annually in the United States. An estimated 20,000 patients in the United States have Cushing’s syndrome. Symptoms vary, but most people have one or more of the following manifestations: high blood sugar, diabetes, high blood pressure, upper body obesity, rounded face, increased fat around the neck, thinning arms and legs, severe fatigue and weak muscles. Irritability, anxiety, cognitive disturbances and depression are also common. Cushing’s syndrome can affect every organ system in the body and can be lethal if not treated effectively.

About Triple-Negative Breast Cancer

Triple-negative breast cancer is a form of the disease in which the three receptors that fuel most breast cancer growth – estrogen, progesterone and the HER-2/neu gene – are not present. Because the tumor cells lack the necessary receptors, treatments that target estrogen, progesterone and HER-2 receptors are ineffective. In 2013, approximately 40,000 women were diagnosed with triple-negative breast cancer. There is no FDA-approved treatment and neither a targeted treatment nor an approved standard chemotherapy regimen for relapsed triple-negative breast cancer patients exists.

About CORT 125134

CORT 125134 is a potent, competitive antagonist at the GR-II receptor, but does not have affinity for the progesterone, estrogen, AR androgen or GR-I (mineralocorticoid) receptors. The company has begun a Phase 1 study of the safety and tolerability of CORT 125134, one of its next-generation selective GR-II antagonists.

Oxford BioMedica Interim Management Statement

The Company announces that it has initiated a pre-clinical research programme to establish proof-of-concept for a Chimeric Antigen Receptor (CAR) T-cell therapy for cancer that combines the specificity of the 5T4 antigen with the delivery efficiency of our proprietary Lentivector platform (Presentation, Oxford BioMedica, NOV 3, 2014, View Source [SID:1234501133]). The goal is to exploit the power of CAR T-cells to target 5T4 expressed on tumour cells from a range of different cancers.

Collectively, these patents generically cover composition-of-matter and methods of use of CUDC-907 as well as a broad range of proprietary chemical entities that target HDAC and PI3K enzymes, and in some instances mammalian target of rapamycin (mTOR), within a single molecule for the treatment of certain human diseases.

"The allowance of the most recent patent application further enhances Curis’ strong intellectual property portfolio and protection around our promising drug candidate, CUDC-907. Additionally, it also emphasizes the novelty and importance of combining two distinct inhibitory moieties that target HDAC and PI3K enzymes in a single molecule," stated Michael Gray, Curis’ Chief Financial and Business Officer. "We are encouraged by the progress being made in CUDC-907’s program and look forward to data from the expansion phase of the trial to understand the role of this molecule in the treatment of patients with diffuse large B cell lymphoma and multiple myeloma."

CUDC-907 is being investigated in a first-in-human Phase 1 study in patients with relapsed/ refractory lymphoma or multiple myeloma. As part of the Phase 1 study, Curis has also opened expansion cohorts to enroll patients with diffuse large B cell lymphoma and multiple myeloma. In addition, Curis also expects to initiate an additional study under a second open IND that will enroll patients with advanced solid tumors, including patients with hormone receptor positive breast cancer, among others.
