FDA Approves Imbruvica (ibrutinib) Plus Obinutuzumab as First Non-Chemotherapy Combination Regimen for Treatment-Naïve Patients with Chronic Lymphocytic Leukemia

In continuation of my update on  ibrutinib

The Janssen Pharmaceutical Companies of Johnson & Johnson announced  the U.S. Food and Drug Administration (FDA) approval of Imbruvica (ibrutinib) in combination with obinutuzumab in treatment-naïve patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), the most common form of leukemia in adults.1 This is the first approval for a non-chemotherapy combination regimen for treatment-naïve patients with CLL/SLL, and marks the tenth FDA approval for Imbruvica since its U.S. launch in November 2013. The approval expands the label for Imbruvica in frontline CLL/SLL beyond its use as a monotherapy to include combination use with obinutuzumab. Imbruvica, a Bruton's tyrosine kinase (BTK) inhibitor, is jointly developed and commercialized by Janssen Biotech, Inc. and Pharmacyclics LLC, an AbbVie company.
"In just a few years, Imbruvica has become an important treatment for chronic lymphocytic leukemia. Imbruvica as a single agent – and now as a combination with obinutuzumab – provides patients with CLL with an alternative to frontline treatment with chemoimmunotherapy," said Carol Moreno, M.D., Ph.D., Consultant Hematologist, Hospital de la Santa Creu Sant Pau, Autonomous University of Barcelona, Barcelona, Spain, and lead investigator of the iLLUMINATE study.
This approval is based on results from the Phase 3 iLLUMINATE study (PCYC-1130). At a median follow-up of 31 months, Imbruvica plus obinutuzumab showed a significant improvement in Independent Review Committee (IRC)-evaluated progression-free survival compared with chlorambucil plus obinutuzumab (median not evaluable [NE] vs. 19 months; hazard ratio [HR] 0.23; 95 percent confidence interval [CI]: 0.15-0.37; P<0.0001), with a 77 percent reduction in risk of progression or death. Patients with high-risk disease (17p deletion/TP53 mutation, 11q deletion, or unmutated IGHV) treated with Imbruvica plus obinutuzumab experienced an 85 percent reduction in risk of progression or death (HR 0.15; 95 percent CI: 0.09-0.27). The IRC-evaluated overall response rate was 89 percent in the Imbruvica plus obinutuzumab arm versus 73 percent in the chlorambucil plus obinutuzumab arm. The data were recently presented in an oral session at the 2018 American Society of Hematology (ASH) Annual Meeting and simultaneously published in The Lancet Oncology.
"This label update builds upon the established efficacy and safety of Imbruvica in the frontline treatment of patients with CLL/SLL, as a monotherapy or in combination with other treatments," said Craig Tendler, M.D., Vice President, Clinical Development and Global Medical Affairs, Janssen Research & Development, LLC. "This milestone represents our continued commitment to develop Imbruvica-based, non-chemotherapy regimens to address the clinical needs of patients living with CLL/SLL."
The FDA also updated the Imbruvica label to include additional long-term efficacy data supporting its use as a monotherapy in CLL/SLL, with approximately five years of follow-up from the Phase 3 RESONATE™ (PCYC-1112) and RESONATE™-2 (PCYC-1115, PCYC-1116) international studies.
Warnings and Precautions include hemorrhage, infections, cytopenias, cardiac arrhythmias, hypertension, second primary malignancies, tumor lysis syndrome, and embryo-fetal toxicity. The most common adverse reactions (occurring in 20 percent or more of patients) of all grades in patients treated with Imbruvica plus obinutuzumab in the iLLUMINATE study were neutropenia (48 percent), thrombocytopenia (36 percent), rash (36 percent), diarrhea (34 percent), musculoskeletal pain (33 percent), bruising (32 percent), cough (27 percent), infusion related reaction (25 percent), hemorrhage (25 percent), and arthralgia (22 percent).
The recommended dose of Imbruvica for CLL/SLL is 420 mg orally once daily until disease progression or unacceptable toxicity as a single agent or in combination with obinutuzumab or bendamustine and rituximab (BR). When administering Imbruvica in combination with rituximab or obinutuzumab, doctors should consider administering Imbruvica prior to rituximab or obinutuzumab when given on the same day.

FDA Approves Osphena (ospemifene) for Moderate to Severe Vaginal Dryness Due to Menopause

Duchesnay Inc., a pharmaceutical company specializing in women’s health, announced   that the FDA has approved its supplemental New Drug Application (sNDA) seeking to add moderate to severe vaginal dryness, a symptom of vulvar and vaginal atrophy (VVA), due to menopause, to the indication of Osphena (ospemifene).
Ospemifene.svg

The sNDA was based on new safety and efficacy data acquired through a confirmatory phase 3 randomized, double blind, placebo-controlled multicenter study evaluating the efficacy and safety of ospemifene in patients with moderate to severe vaginal dryness. Osphena is non-hormonal and helps improve specific vaginal tissues by increasing superficial cells, decreasing parabasal cells and reducing vaginal pH.
Prior to this approval, Osphena was indicated only for the treatment of moderate to severe dyspareunia (painful intercourse), also a symptom of VVA, due to menopause.
“Many menopausal women are not aware that vaginal dryness is one of the two most common and most bothersome symptoms (MBS) of vulvovaginal atrophy due to menopause. FDA’s approval of this additional indication affirms Osphena’s safety and effectiveness for treating moderate to severe vaginal dryness, broadening its benefits to a larger number of menopausal women,” affirmed Dr. James A. Simon, Clinical Professor of Obstetrics and Gynecology at George Washington University.
Before menopause, estrogen helps maintain the thickness, elasticity and lubrication of vaginal tissues. However, as women age, estrogen levels drop, causing changes in these tissues, which can lead to dryness, itching, burning and painful intercourse.
“With the addition of moderate to severe vaginal dryness to Osphena’s indication, Duchesnay USA can now help postmenopausal women suffering from this symptom of VVA”, explained Dean Hopkins, General Manager of Duchesnay USA. “With this new indication, Osphena now provides an oral option for women who prefer a non-hormonal treatment alternative.”

New One-Dose Flu Drug Shows Promise

An experimental single-dose flu drug shows promise as a new way to alleviate the misery of influenza, researchers say. 

Baloxavir marboxil.svg
The drug  called baloxavir (structre)  worked better than no treatment in one phase of a new study. The study also found it as effective as the current standard drug, oseltamivir (Tamiflu), at controlling symptoms such as coughing, sore throat, headache, fever, muscle and joint pain, and fatigue.
Moreover, in light of concerns about flu-drug resistance, most patients treated with baloxavir responded as expected, the study authors said.
"There are few approved influenza antivirals, and current treatments have limitations," said study lead author Dr. Frederick Hayden, of the University of Virginia School of Medicine.
"For example, currently circulating influenza viruses are resistant to the older class of antivirals," he said. These include the drugs amantadine (brand name Symmetrel) and rimantadine (Flumadine).
Resistance is also growing to the class of drugs including widely used Tamiflu and Relenza (zanamivir), Hayden said. "Consequently, there are medical needs for new anti-influenza agents with different mechanisms of action and greater potency," he added.
Hayden, professor emeritus of clinical virology and medicine, said the new study indicates that baloxavir resolves flu symptoms as quickly, effectively and safely as current options, without yet raising concerns about resistance. It also demonstrated "significantly greater antiviral effects," he added.
Also, while Tamiflu must be taken twice a day for five days, baloxavir requires just one dose.
The investigation was funded by the drug company Shionogi, Inc., which developed and manufactures baloxavir.
Baloxavir is approved for use in Japan. In the United States, it remains an "investigational drug," with the U.S. Food and Drug Administration expected to decide on approval by the end of this year.
The new study, which was published Sept. 6 in the New England Journal of Medicine, unfolded in two trials, both involving otherwise healthy flu patients at low risk for influenza complications.
One trial was conducted during the 2015-2016 flu season. About 400 patients, aged 20 to 64, received one of three doses of baloxavir (ranging from 10 to 40 milligrams) or a placebo. Flu symptoms eased notably faster among all three baloxavir groups, compared with placebo (untreated) patients, the findings showed.
The following flu season, nearly 1,100 patients, aged 12 to 64, were treated with baloxavir or Tamiflu. The drugs relieved symptoms in roughly the same time period, with similar side-effect risk.
However, about 10 percent of the baloxavir patients had a less than robust response to the drug. Hayden acknowledged that "the clinical and public health implications of reduced susceptibility to baloxavir are not fully understood."
Dr. Timothy Uyeki, author of an accompanying journal editorial, heads the influenza division at the U.S. Centers for Disease Control and Prevention's National Center for Immunization and Respiratory Diseases.
"There is a need for antiviral drugs with new mechanisms of action," he agreed.Uyeki highlighted the benefit of baloxavir's single-dose regimen. Besides its convenience, it "avoids concerns about compliance with a five-day treatment course of oseltamivir," he said.
But he also stressed the need for further testing.
It remains unclear what benefits might accrue from combining baloxavir with Tamiflu, Uyeki noted.
Also, he cautioned, the current research only included otherwise healthy people aged 12 to 64 who were not at high risk for flu complications. Whether baloxavir will benefit high-risk groups -- young children, the elderly, pregnant women and others with underlying chronic medical conditions -- remains unknown, Uyeki said.
"A lot more studies are needed of the clinical benefit of baloxavir treatment of influenza in high-risk outpatients," he added.

FDA Approves New Indication for Envarsus XR (tacrolimus extended-release tablets)


In continuation of my update on Tacrolimus

Veloxis Pharmaceuticals announced today that the U.S. Food & Drug Administration (FDA) approved a new indication for Envarsus XR (tacrolimus extended-release tablets) to prevent organ rejection in de novo kidney transplant patients in combination with other immunosuppressants. This indication is commonly referred to as the de novo indication.
Envarsus XR was approved for the prophylaxis of organ rejection in kidney transplant patients converted from tacrolimus immediate-release formulations in 2015 and has already been used in the conversion setting in more than 90% of the transplant centers in the U.S.  The approval for de novo use provides an important new treatment option for kidney transplant patients and providers, where significant unmet need currently exists.
"Today marks the beginning of an exciting new chapter in immunosuppression.  Kidney transplant patients will now be able to receive a refined and simplified gold standard treatment regimen from the beginning of the kidney transplant journey," said Ulf Meier-Kriesche, M.D. Chief Scientific Officer at Veloxis Pharmaceuticals, Inc.
The FDA's approval is based on the Phase 3 clinical development program which was a randomized, double-blind, double-dummy, Phase III study in 543 de novo kidney transplant patients that demonstrated comparable efficacy and safety compared to twice-daily tacrolimus (Prograf®).
The primary endpoint of the study was a composite endpoint of treatment failure (biopsy-proven acute rejection or BPAR, graft failure, loss to follow up or death) that was evaluated after a 12-month treatment period to demonstrate the non-inferiority of Envarsus® compared to Prograf®. The treatment failure rate for Envarsus® was 18.3% compared to 19.6% for Prograf®.    
"There are approximately 200,000 patients living with a kidney transplant today and we have seen a significant number of them convert to Envarsus XR since our launch in December 2015.  With the addition of the de novo indication, the roughly 16,000 adult patients who receive a kidney transplant each year will now have access to Envarsus XR following surgery. This approval is another example of Veloxis's commitment to transplant and the patients, donors and providers that make it all possible," said Craig A. Collard, Chief Executive Officer of Veloxis Pharmaceuticals A/S.

FDA Approves Motegrity (prucalopride) for Adults with Chronic Idiopathic Constipation (CIC)


Prucalopride.svg

SHPG) has announced that the U.S. Food and Drug Administration (FDA) has approved Motegrity (prucalopride), a once-daily, oral treatment option for adults with Chronic Idiopathic Constipation (CIC).
Motegrity, a selective serotonin-4 (5-HT4) receptor agonist, provides a different class of treatment for CIC that works by enhancing colonic peristalsis to increase bowel motility. Motegrity is expected to launch in 2019 in the United States, where an estimated 35 million adults are living with CIC.  While not all patients may be right for treatment, Motegrity represents an important new option.
“The approval of Motegrity marks a new day in the treatment of CIC,” said Howard Mayer, M.D., Senior Vice President and Chief Medical Officer, Shire. “This significant milestone reinforces our continued commitment to the GI community and advances our goal of addressing the unmet need of patients suffering from rare, specialized and common GI conditions.”
The efficacy of once-daily treatment with Motegrity was evaluated in six double-blind, placebo-controlled, randomized, multicenter clinical studies lasting 12 weeks (studies 1-5) or 24 weeks (study 6) Of the 2,484 patients, most were female (76%) and Caucasian (76%), with an average age of 47 (+/- 16 years).
“As a gastroenterologist, it’s important for me to help patients with CIC find a treatment that works well for them,” said Brooks Cash, M.D., Chief of the Division of Gastroenterology, Hepatology, and Nutrition at the University of Texas Health Science Center at Houston. “It’s exciting to be able to now offer my patients a new treatment option that addresses colonic peristalsis.”
 During studies, significantly more patients taking Motegrity achieved the primary endpoint (an average of ≥3 complete spontaneous bowel movements [CSBMs] per week over 12 weeks, considered normalization of BM frequency) than those in the placebo group (19-38% Motegrity ≤2 mg vs. 10-20% placebo) across five of six trials. A rapid response was seen with Motegrity as early as week 1, with improvements maintained throughout 12 weeks of treatment.1 The FDA has requested that Shire conduct five post-marketing studies evaluating the pharmacokinetics, efficacy, and safety of Motegrity in pediatric patients with CIC (6 months old to less than 18 years of age) and pregnant and lactating women with CIC treated with Motegrity.
Motegrity is contraindicated in patients with a history of hypersensitivity to Motegrity. Reactions include dyspnea, rash, pruritus, urticaria, and facial edema have been observed. Motegrity is also contraindicated in patients with intestinal perforation or obstruction due to structural or functional disorder of the gut wall, obstructive ileus, severe inflammatory conditions of the intestinal tract such as Crohn’s disease, ulcerative colitis, and toxic megacolon/megarectum.
In clinical trials, suicides, suicide attempts, and suicidal ideation have been reported. A causal association between treatment with Motegrity and an increased risk of suicidal ideation and behavior has not been established. Monitor all patients treated with Motegrity for persistent worsening of depression or the emergence of suicidal thoughts and behaviors. Counsel patients, their caregivers, and family members of patients to be aware of any unusual changes in mood or behavior and alert the healthcare provider. Instruct patients to discontinue Motegrity immediately and contact their healthcare provider if they experience any of these symptoms.
Most common adverse reactions (≥2%) are headache, abdominal pain, nausea, diarrhea, abdominal distension, dizziness, vomiting, flatulence and fatigue. Overall, discontinuation due to adverse events was low (5% Motegrity 2 mg once daily; 3% placebo). If reported, adverse events of diarrhea or headache typically resolved within a few days.1 In addition, cardiovascular safety was evaluated in a MACE (major adverse cardiovascular events) analysis of the double-blind, placebo-controlled and open-label studies. It was also assessed in a retrospective observational study, which demonstrated no increase in the risk of MACE with Motegrity relative to polyethylene glycol (PEG).
CIC is a common condition affecting roughly 14% of the adult population. Symptoms can range from straining and bloating, to infrequent, or incomplete bowel movements. While “idiopathic” by definition (meaning the exact cause is not known), it is believed that CIC may be caused by insufficient movement of the colon muscle

FDA Grants Priority Review Designation for Heron Therapeutics' NDA for HTX-011, a Non-Opioid for Postoperative Pain Management


      Bupivacaine skeletal.svg





Heron Therapeutics, Inc. (Nasdaq: HRTX), a commercial-stage biotechnology company, announced that the U.S. Food and Drug Administration (FDA) has accepted the new drug application (NDA) for Heron's investigational agent, HTX-011, and has granted it a Priority Review designation. HTX-011 is a long-acting, extended-release formulation of the local anesthetic bupivacaine in a fixed-dose combination with the anti-inflammatory meloxicam for the management of postoperative pain. HTX-011 is the first and only dual-action fixed-combination product specifically designed to address both postoperative pain and inflammation in a single administration at the surgical site. The NDA for HTX-011, which was submitted on October 30, 2018, comprises data from five Phase 2 clinical trials and two Phase 3 clinical trials that included over 1,000 patients undergoing five different surgical procedures. The FDA also indicated that it is not currently planning to hold an advisory committee meeting to discuss this application. The FDA set a Prescription Drug User Fee Act goal date of April 30, 2019."We are pleased to receive Priority Review designation for the HTX-011 NDA," said Barry D. Quart, Pharm.D., Chief Executive Officer of Heron. "We believe that HTX-011 could have a considerable impact on the lives of patients by significantly reducing the proportion of patients who experience severe pain and receive opioids after surgery, especially at discharge. We look forward to continuing to work closely with the FDA during the review process with the goal of bringing this important product to patients in 2019."
The FDA had previously granted Breakthrough Therapy designation for HTX-011 based on the results of Phase 2 studies and two completed Phase 3 studies, which showed that HTX-011 produced significant reductions in both pain intensity and the need for opioids through 72 hours post-surgery compared to placebo and bupivacaine solution, the standard-of-care. The FDA has now granted Priority Review designation to the NDA for HTX-011. Priority Review designation is for drugs that, if approved, would be significant improvements in the safety or effectiveness of the treatment or prevention of serious conditions. HTX-011 is the first and only non-opioid, long acting local anesthetic to demonstrate in Phase 3 studies a statistically significant reduction in severe pain and an increase in the number of patients who require no opioids for 72 hours postoperatively versus bupivacaine solution, the standard-of-care. The overall safety profile of HTX-011, administered locally into the surgical site without a needle, was similar to that of the well-established safety profile of bupivacaine solution, without evidence of meloxicam-related toxicities.
"Despite ongoing efforts to prevent opioid abuse, patients continue to receive large quantities of opioids for postsurgical pain," said Jay Redan, M.D., FACS, Medical Director of Minimally-Invasive General Surgery at Florida Hospital Celebration Health. "There is a significant need for safe, effective and non-addictive options that can decrease opioid exposure and improve the patient recovery experience, as well as make an impact on the opioid epidemic by significantly reducing the amount of opioids necessary to take home for pain management."


About HTX-011 for Postoperative Pain
HTX-011, which utilizes Heron's proprietary Biochronomer® drug delivery technology, is an investigational, long-acting, extended-release formulation of the local anesthetic bupivacaine in a fixed-dose combination with the anti-inflammatory meloxicam for the management of postoperative pain. By delivering sustained levels of both a potent anesthetic and a local anti-inflammatory agent directly to the site of tissue injury, HTX-011 was designed to deliver superior pain relief while reducing the need for systemically administered pain medications such as opioids, which carry the risk of harmful side effects, abuse and addiction. HTX-011 has been shown to reduce pain significantly better than placebo or bupivacaine alone in five diverse surgical models: hernia repair, abdominoplasty, bunionectomy, total knee arthroplasty and breast augmentation. HTX-011 was granted Fast Track designation from the FDA in the fourth quarter of 2017 and Breakthrough Therapy designation in the second quarter of 2018. Heron submitted an NDA to the FDA for HTX-011 in October of 2018 and received Priority Review designation in December 2018. The FDA set a Prescription Drug User Fee Act goal date of April 30, 2019.

Lynparza (olaparib) Approved by US FDA for First-Line Maintenance Therapy in BRCA-Mutated Advanced Ovarian Cancer


In continuation of my update on olaparib
AstraZeneca and Merck & Co., Inc., (Merck: known as MSD outside the US and Canada)  announced that the US Food and Drug Administration (FDA) has approved Lynparza for use as maintenance treatment of adult patients with deleterious or suspected deleterious germline or somatic BRCA-mutated (gBRCAm or sBRCAm) advanced epithelial ovarian, fallopian tube or primary peritoneal cancer who are in complete or partial response to 1st-line platinum-based chemotherapy. Patients with gBRCAm advanced epithelial ovarian, fallopian tube or primary peritoneal cancer are selected for therapy based on an FDA-approved companion diagnostic for Lynparza.
This is the first regulatory approval for a PARP inhibitor in the 1st-line maintenance setting for BRCAm advanced ovarian cancer. The approval was based on positive results from the pivotal Phase III SOLO-1 trial  in which Lynparza reduced the risk of disease progression or death by 70% in patients with BRCAm advanced ovarian cancer who were in complete or partial response to platinum-based chemotherapy (HR 0.30 [95% CI 0.23-0.41], p<0.0001) compared to placebo.
Dave Fredrickson, Executive Vice President, Head of the Oncology Business Unit, AstraZeneca, said: “Women with ovarian cancer are often first diagnosed with advanced disease, which is associated with poor outcomes. In SOLO-1, Lynparza in the first-line maintenance setting reduced the risk of disease progression or death by 70 percent for patients with BRCAm advanced ovarian cancer. Today’s approval is a critical advancement and brings us closer to our goal of helping these patients achieve long-term remission.”
Roy Baynes, Senior Vice President and Head of Global Clinical Development, Chief Medical Officer, Merck Research Laboratories, said: “The expanded approval of Lynparza based upon the SOLO-1 trial has the potential to change medical practice and reinforces the importance of knowing a woman’s BRCA status at diagnosis. We continue to work in collaboration with AstraZeneca on our overall goal of improving outcomes for patients.”
In the SOLO-1 trial, with median 41 months of follow-up, the median progression-free survival (PFS) for patients treated with Lynparza (n=260) was not reached compared to 13.8 months for patients treated with placebo (n=131). In the trial, 60% of patients receiving Lynparza remained progression-free at 3 years compared to 27% of patients receiving placebo. The data from the SOLO-1 trial can be found in the October 21, 2018, online issue of the New England Journal of Medicine.
The most common adverse reactions (ARs) in ≥10% of patients taking Lynparza in the SOLO-1 trial were nausea (77%), fatigue (67%), abdominal pain (45%), vomiting (40%), anemia (38%), diarrhea (37%), constipation (28%), upper respiratory tract infection/influenza/nasopharyngitis/bronchitis (28%), dysgeusia (26%), dizziness (20%), decreased appetite (20%), neutropenia (17%), dyspepsia (17%), dyspnea (15%), leukopenia (13%), UTI (13%), thrombocytopenia (11%) and stomatitis (11%). The most common Grade ≥3 ARs were anemia (21%) and neutropenia (6%). Dose interruptions due to an AR of any grade occurred in 52% of patients receiving Lynparza and 17% of those receiving placebo. Seventy-two percent (n=186) of patients on Lynparza remained on the recommended starting dose of 300 mg (two 150 mg tablets twice daily) versus 97% (n=126) on placebo. Adverse reactions that most frequently led to discontinuation in patients treated with Lynparza were fatigue (3.1%), anemia (2.3%), and nausea (2.3%). Eighty-eight percent (n=230) of patients on Lynparza continued treatment without an AR-related discontinuation versus 98% (n=127) on placebo.
Kathleen Moore, Co-Principal Investigator of the SOLO-1 trial and Associate Director for Clinical Research, Stephenson Cancer Center at The University of Oklahoma, Oklahoma City, Oklahoma, said: “SOLO-1 is truly a landmark trial in gynecologic cancer. This approval will likely change the way we treat women with BRCA-mutated advanced ovarian cancer. The ability to offer this important first-line maintenance treatment option to eligible patients may slow down or even stop the natural course of disease progression.”
AstraZeneca and Merck are exploring additional trials in ovarian cancer, including the ongoing GINECO/ENGOTov25 Phase III trial, PAOLA-1. This trial is testing the effect of Lynparza in combination with bevacizumab as a maintenance treatment for patients with newly-diagnosed advanced ovarian cancer, regardless of their BRCA status. Results are expected during the second half of 2019.

MONUROL® (fosfomycin tromethamine) Structural Formula - Illustration


Nabriva Therapeutics plc (NASDAQ: NBRV), a clinical-stage biopharmaceutical company announced that the U.S. Food and Drug Administration (FDA) has accepted the New Drug Application (NDA) and granted a priority review for Contepo™ (fosfomycin for injection) to treat complicated urinary tract infections (cUTIs), including acute pyelonephritis. The acceptance of the NDA indicates that the FDA has deemed the application sufficiently complete to allow a substantive review. The PDUFA (Prescription Drug User Fee Act) goal date for the completion of the FDA’s review of the Contepo NDA is June 30, 2019. In addition to priority review, Contepo has been granted Qualified Infectious Disease Product (QIDP) and Fast Track designations by the FDA for the treatment of several serious infections, including cUTI.
“The acceptance of the Contepo NDA marks another major milestone for Nabriva Therapeutics, demonstrating our commitment to bring novel anti-infective agents that address the urgent, unmet medical need in patients with serious infections,” said Dr. Jennifer Schranz, chief medical officer of Nabriva Therapeutics. “Contepo, if approved in the United States, represents a first-in-class intravenous antibiotic with broad spectrum activity against Gram-negative and Gram-positive organisms, including ESBL-producing Enterobacteriaceae and other contemporary multi-drug resistant (MDR) organisms.”
The NDA submission is utilizing the 505(b)(2) regulatory pathway and is supported by a robust data package, including a pivotal Phase 2/3 clinical trial (known as ZEUS™), which met its primary endpoint of statistical non-inferiority to piperacillin/tazobactam in patients with cUTI, including acute pyelonephritis.
In the NDA acceptance letter, the FDA stated that no filing or potential review issues were identified. In addition, the Agency stated that it has not referred Contepo to an advisory committee meeting at this time.

Experimental drug can protect against Ebola in a single dose


Dr. Thomas Geisbert, a world-renowned Ebola researcher at The University of Texas Medical Branch, said that previous therapeutics typically were of the "one bug, one drug" variety. But because of the unpredictable nature and variety of the Ebola virus, scientists have been seeking a way to protect against different strains of the virus.

Our experimental drug can protect against all forms of Ebola known to harm people, suggesting that it will continue to protect people if the Ebola viruses evolve over time," said Geisbert, who is a professor of microbiology and immunology at UTMB.
The team of scientists demonstrated that a two-antibody cocktail called MBP134 could fully protect nonhuman primates and ferrets against lethal Ebola virus infections of caused by the Bundibugyo and Sudan strain as well as the deadliest Zaire strain that caused the 2013-16 epidemic in West Africa and the current outbreak in the Democratic Republic of Congo.
"We were able to protect the nonhuman primates against all the Ebola species plaguing people at a single low dose," said Larry Zeitlin, president of Mapp Biopharmaceutical Inc. "Further studies exploring even lower doses could open the door to treatment via auto-injectors like the kind used for allergic reactions. The ability to quickly and efficiently provide protection against all Ebola viruses in a single dose would reduce the burden on health care workers in the field during outbreaks, especially in regions that have a less-developed infrastructure."

FDA Approves Tolsura (SUBA®-itraconazole capsules) for the Treatment of Certain Fungal Infections

In continuation of my update on Itraconazole

Image result for itraconazole

Mayne Pharma Group Limited (ASX: MYX) announced,  that the US Food and Drug Administration (FDA) has approved the New Drug Application (NDA) for Tolsura™ (SUBA®-itraconazole) 65mg capsules. Tolsura is a new formulation of itraconazole indicated for the treatment of certain systemic fungal infections in adult patients.
Tolsura is indicated for the treatment of blastomycosis (pulmonary and extrapulmonary), histoplasmosis (including chronic cavitary pulmonary disease and disseminated, non-meningeal histoplasmosis) and aspergillosis (pulmonary and extrapulmonary, in patients who are intolerant of or who are refractory to amphotericin B therapy). These serious infections most commonly occur in vulnerable or immunocompromised patients, for example, those with a history of cancer, transplants (solid organ or bone marrow), HIV/AIDS, or chronic rheumatic disorders, and are often associated with high mortality rates or long-term health issues.
Mayne Pharma's CEO, Mr Scott Richards said, "We are very pleased to have received FDA approval of this patented formulation of itraconazole which incorporates Mayne Pharma's proprietary SUBA technology to improve the bioavailability of poorly soluble drugs. Reformulation of existing drugs plays an important role in improving patient compliance and clinical outcomes. We are proud to offer a new treatment option for patients with these life-threatening infections. We believe physicians will appreciate having access to Tolsura, which has been shown in clinical studies to have increased bioavailability and significantly reduced variability when compared to conventional oral itraconazole capsules."
"After many years of research and development and working closely with key global opinion leaders in infectious disease management, Tolsura represents a major milestone in the SUBA (SUper-BioAvailable) drug delivery platform at Mayne Pharma."
The Company will directly commercialise Tolsura and plans to launch in January 2019 with a new institutional sales team focused primarily on hospital-based infectious disease specialists. Tolsura has four granted patents from the United States Patent and Trademark Office with expiry dates ranging from 2023 to 2033.
The US anti-fungal triazole market has a current value of US$600m according to IQVIA and based on the clear unmet clinical need in serious systemic infections, the addressable market is estimated at US$200m[1].
Mayne Pharma directly markets more than 60 products in the US including three patent protected dermatology products Fabior® (tazarotene) foam, Sorilux® (calcipotriene) foam and Doryx® MPC (doxycycline) delayed-release tablets. The Company recently acquired Lexette® (halobetasol) foam used to treat plaque psoriasis which it expects to also launch in January 2019.
