In the 10 months following the Jan. 30, 2016, signing of the agreement, Alere has suffered a series of damaging business developments, including the government eliminating the billing privileges of a substantial Alere division, the permanent recall of an important product platform, multiple new government subpoenas, including two new criminal subpoenas, and a five-month delay in filing its 10K coupled with admissions of internal control failures requiring restatement of its 2013-2015 financials.

"Alere is no longer the company Abbott agreed to buy 10 months ago," said Scott Stoffel, divisional vice president of external communications, Abbott. "These numerous negative developments are unprecedented and are not isolated incidents brought on by chance. We have attempted to secure details and information to assess these issues for months, and Alere has blocked every attempt. This damage to Alere’s business can only be the result of a systemic failure of internal controls, which combined with the lack of transparency, led us to filing this complaint."

Under terms of the merger agreement, Abbott may terminate the transaction if adverse events materially change Alere’s long-term prospects. Abbott filed its complaint seeking termination in the Delaware Court of Chancery, citing these events among others as material adverse events.

On December 7, 2016 Panther Biotechnology, Inc. reported that it has received positive feedback from the submission presented to the U.S. Food and Drug Administration ("FDA") pursuant to a Pre-IND (Investigational New Drug) meeting with the Division of Oncology Products 1 (DOP1) of the Center for Drug Evaluation and Research (CDER) of the FDA (Press release, Panther Biotechnology, DEC 7, 2016, View Source [SID1234517402]). The purpose of the requested meeting was to obtain FDA’s input regarding Panther’s plans for the development of TRF-DOX, Panther’s novel transferrin-doxorubicin conjugate initially planned for the treatment of platinum-resistant ovarian cancer. In preparation for the meeting, Panther submitted a Pre-IND Package to FDA that described the information Panther intends on submitting in the TRF-DOX IND submission planned in 2017. The IND is the regulatory vehicle that will allow for the initiation of clinical trials with TRF-DOX initially for the treatment of ovarian cancer.

Panther submitted the request to seek guidance on a Phase 2a Open Label Sequential Cohort, Ascending Dose, Blinded, DOXIL controlled Study to Evaluate the Safety, Pharmacokinetics and Preliminary Efficacy of Multiple Doses of TRF-DOX Administered Intravenously every 4 weeks for up to 12 months to patients with Advanced Platinum-refractory or -resistant Ovarian Cancer. The primary objective will be to evaluate the safety and tolerability of TRF-DOX administered intravenously to subjects with advanced platinum-refractory or resistant ovarian cancer for up to 12 months. Secondary objectives are tumor response rate (complete and partial responses) assessed every 3 months for 12 months following treatment according to Response Evaluation Criteria in Solid Tumors version 1.1. (RESIST) criteria, progression-free survival at 6 and 12 months following first injection of TRF-DOX and overall survival at 6 and 12 months following first injection of TRF-DOX.

FDA reviewed Panther’s manufacturing, preclinical pharmacology and toxicology, and clinical plans for TRF-DOX and provided specific feedback. In general, FDA agreed with Panther’s plans and offered further recommendations and comments. The manufacturing and nonclinical pharmacology and toxicology plans with TRF-DOX were deemed adequate pending review of actual data by FDA in the IND.

In addition, FDA had input into the design of the Phase 2b clinical trial with TRF-DOX which will be considered in the protocol submitted with the IND.

"This is a significant leap for Panther as we prepare to enter clinical trials in the US and we look forward to getting started," stated Evan Levine, Chief Executive Officer of Panther. "We are extremely pleased and thankful for not only the valuable feedback we received from FDA but also from the productive recommendations to manage TRF-DOX through the next stage of clinical development. Based on earlier encouraging clinical results, we believe we may have a greater opportunity for increasing clinical benefit for patients receiving treatment."
TRF-DOX binds to transferrin receptors on tumor cells, inhibits cancer cell proliferation and causes cell death. TRF-DOX has been shown to exhibit increased cytotoxicity relative to unconjugated doxorubicin toward a variety of cancer cell lines and reduced cytotoxicity to normal cells. In addition to improvements in cytotoxicity and selectivity, TRF-DOX exhibits cytotoxic effects in many multidrug-resistant cells in vitro. Tumor targeting of doxorubicin to transferrin receptors on the cell membranes of tumor cells is intended to improve the therapeutic index of doxorubicin and to reduce the development of doxorubicin resistance.

On December 6, 2016 Puma Biotechnology, Inc. (NYSE: PBYI), a biopharmaceutical company, reported the initiation of a Managed Access Program for PB272 (neratinib) (Press release, Puma Biotechnology, DEC 6, 2016, View Source [SID1234516961]).

Puma’s Managed Access Program for neratinib will enable participation from countries outside the United States, including European Union Member States, where permitted by applicable rules, procedures and regulatory authorities. The program will provide access to neratinib for the treatment of early stage HER2-positive breast cancer (extended adjuvant setting), HER2-positive metastatic breast cancer and HER2-mutated solid tumors. Patients must not be able to participate in any ongoing neratinib clinical trial to qualify for Puma’s managed access program. Patients in the managed access program will be given neratinib and will be instructed to take a prophylaxis during treatment to manage neratinib-related diarrhea, which the Company expects will consist of high dose loperamide and budesonide.

Puma Biotechnology has partnered with Caligor Opco LLC, which specializes in early access to medicines, to implement and oversee the Managed Access Program for neratinib.

"The guiding principle behind our Managed Access Program is to provide neratinib — through physician-requested access — to patients with significant unmet medical needs as soon as practical, in a manner that is safe, ethical, compliant and effective," said Alan H. Auerbach, Chief Executive Officer and President of Puma. "With Caligor managing the day-to-day operations of the program, we can direct our efforts toward our regulatory filings and implementing our plans for commercialization."

On December 5, 2016 Bio-Path Holdings, Inc., (NASDAQ: BPTH), a biotechnology company leveraging its proprietary DNAbilize liposomal delivery and antisense technology to develop a portfolio of targeted nucleic acid cancer drugs, reported that a review of BP1001 data as a treatment for chronic myelogenous leukemia (CML) was presented in a poster at the 58th Annual American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting taking place from December 3-6, 2016 in San Diego, CA (Filing, 8-K, Bio-Path Holdings, DEC 6, 2016, View Source [SID1234516978]).

Ana Tari Ashizawa, Ph.D., Bio-Path’s director of research, presented the poster titled "BP1001, a Novel Therapeutic for Chronic Myelogenous Leukemia." The results demonstrated that BP1001 decreased the proliferation of Gleevec (imatinib)-resistant CML cells in a dose-dependent manner. In addition, BP1001 pretreatment enhanced the inhibitory effects of Sprycel (dasatinib) in CML cells, leading to cell death. Five CML blast phase patients were enrolled in the first cohort (5 mg/m2 BP1001) of the Phase 1 BP1001 clinical study. Two CML patients, who had T315I mutation, showed significant reductions in circulating blasts during treatment. One patient’s blasts were reduced from 89% to 12%, while another patient’s blasts were reduced from 24% to 7%.

"These patient data, supported by previous in vivo and in vitro results, suggest that BP1001 has the potential to treat the 33% of CML patients who are resistant to Gleevec, the current standard of care. Sprycel is a second-generation tyrosine kinase inhibitor that is often used for Gleevec resistant patients. We are pleased that our preclinical results showed that BP1001 can enhance Sprycel activity in CML cells. These positive data give us confidence that BP1001 could play a valuable role in treating this patient population and encourage us to move forward with the initiation of our safety segment of the Phase 2 trial in patients with CML," said Peter Nielsen, chief executive officer of Bio-Path Holdings.

About BP1001

BP1001 (Liposomal Grb2 antisense) is Bio-Path’s lead product candidate, a neutral-charge, liposome-incorporated antisense drug designed to inhibit protein synthesis of Grb2 (growth factor receptor bound protein 2). Grb2 plays an essential role in cancer cell activation via the RAS pathway. Grb2 is an adapter protein that bridges signals between activated and mutated tyrosine kinases, such as Flt3, c-Kit, and Bcr-Abl, and the Ras pathway, leading to activation of the ERK and AKT proteins. Inhibition of Grb2 by BP1001 represents a significant advance in treating cancers with activated tyrosine kinases using a target not druggable with antibodies or kinase inhibitors. Inhibition of Grb2 has been demonstrated to halt cell proliferation and enhance cell killing by chemotherapeutic agents without added toxicity.

Abstract #4149: Case Match Control Analysis of Propel Reveals Survival Advantage for Patients with Relapsed/Refractory (R/R) Peripheral T-Cell Lymphoma (PTCL) Treated with Pralatrexate

In this retrospective, observational study, 80 patients out of 109 treated on the PROPEL study were successfully matched 1:1 with the control population. A highly significant difference in the Overall Survival between the control population and the pralatrexate group was observed. The overall survival observed in the control population was 4.04 months (95% CI 2.60, 6.01) which was consistent with historical controls, while the median OS in for pralatrexate treated cohort was 14.78 months (95% CI 10.61-22.31). The most common adverse reactions from the PROPEL study were mucositis (70%), thrombocytopenia (41%), nausea (40%), and fatigue (36%). The most common serious adverse events were pyrexia, mucositis, sepsis, febrile neutropenia, dehydration, dyspnea, and thrombocytopenia. See below for Important Safety Information.

"In this case match controlled study, the overall survival observed in the pralatrexate group was over three-fold higher than a case matched control group," said Owen A. O’Connor, MD, PhD, Director of the Center for Lymphoid Malignancies, Professor of Medicine and Experimental Therapeutics at Columbia Medical Center, New York Presbyterian Medical Center. "The PROPEL study, which was a Phase 2, open-label, single-arm, multi-center, international trial, included patients that were heavily pretreated, with a median of three prior systemic therapies (ranging between 1 and 12). This is one of the first times a case match control analysis has been used to understand the impact of a drug on the outcome of a rare disease, like PTCL. Importantly, we believe this may be a valuable paradigm that can be used in other orphan diseases in cancer medicine."

"We are honored to present this important data at the 58th ASH (Free ASH Whitepaper) Meeting," said Rajesh C. Shrotriya, MD, Chairman and Chief Executive Officer of Spectrum Pharmaceuticals. "We are encouraged to see positive data continuing to emerge from the PROPEL study that was the basis for FOLOTYN’s approval. FOLOTYN was the first drug approved for the treatment of relapsed or refractory PTCL and continues to have the leading market share in 2nd line therapy. PTCL is an aggressive disease with a poor prognosis and we are excited that FOLOTYN has the potential to improve outcome for PTCL patients. We are also looking forward to emerging new data in combination treatments that might prove to benefit PTCL patients in earlier lines of treatment and with the possibility to include FOLOTYN in future PTCL first line regimens."

About FOLOTYN

FOLOTYN, (pralatrexate injection), a folate analogue metabolic inhibitor, was discovered by Memorial Sloan-Kettering Cancer Center, SRI International and Southern Research Institute and developed by Allos Therapeutics. In September 2009, the U.S. Food and Drug Administration (FDA) granted accelerated approval for FOLOTYN for use as a single agent for the treatment of patients with relapsed or refractory PTCL. This indication is based on overall response rate. Clinical benefit such as improvement in progression-free survival or overall survival has not been demonstrated. FOLOTYN has been available to patients in the U.S. since October 2009. An updated analysis of data from PROPEL, the pivotal study of FOLOTYN in patients with relapsed or refractory PTCL, was published in the March 20, 2011 issue of the Journal of Clinical Oncology. FOLOTYN has patent protection through July 2022, based on a five-year patent term extension through the Hatch-Waxman Act.

Important FOLOTYN Safety Information

Warnings and Precautions

FOLOTYN may suppress bone marrow function, manifested by thrombocytopenia, neutropenia, and anemia. Monitor blood counts and omit or modify dose for hematologic toxicities.

Mucositis may occur. If greater-than or equal to Grade 2 mucositis is observed, omit or modify dose. Patients should be instructed to take folic acid and receive vitamin B12 to potentially reduce treatment-related hematological toxicity and mucositis.

Fatal dermatologic reactions may occur. Dermatologic reactions may be progressive and increase in severity with further treatment. Patients with dermatologic reactions should be monitored closely, and if severe, FOLOTYN should be withheld or discontinued. Tumor lysis syndrome may occur. Monitor patients and treat if needed.

FOLOTYN can cause fetal harm. Women should avoid becoming pregnant while being treated with FOLOTYN and pregnant women should be informed of the potential harm to the fetus.
