Isis Phase II drug APOIIIRx slashes triglycerides by 64%

Isis Pharmaceuticals is "very encouraged" by a second set of mid-stage data for its heart drugAPOIIIRx, which shows that it can substantially slash levels of dangerous fats in the blood. 

In a 26-patient Phase II trial, patients with severely high levels of triglycerides taking Isis' drug alongside fibrates experienced 64% drop in triglycerides, and a 70% drop in apolipoprotein C-III (apoC-III), a component of 'bad' low-density lipoprotein

New therapy for pancreatic cancer: Phase III clinical trial currently recruiting Australian patients

Currently there is a clinical trial that is recruiting patients from around the globe including sites across Australia. The trial is testing MM-398; a therapy that uses the latest in nanotechnology to deliver the chemotherapeutic agent irinotecan encased in a liposome to cancer patients.1 In particular this trial, named NAPOLI-1 (NAnoliPOsomaL Irinotecan) is recruiting patients with pancreatic cancer who have previously been treated with the chemotherapy agent gemcitabine unsuccessfully i.e. their disease has gone on to spread/progress despite this treatment.2,3

Irinotecan (Camptosar, Pfizer; Campto, Yakult Honsha) is a drug used for the treatment of cancer.
Irinotecan prevents DNA from unwinding by inhibition of topoisomerase 1. In chemical terms, it is a semisynthetic analogue of the natural alkaloid camptothecin.
Its main use is in colon cancer, in particular, in combination with other chemotherapy agents. This includes the regimen FOLFIRI, which consists of infusional 5-fluorouracil,leucovorin, and irinotecan.
Irinotecan received accelerated approval by the U.S. Food and Drug Administration (FDA) in 1996 and full approval in 1998. During development, it was known as CPT-11.
Irinotecan is activated by hydrolysis to SN-38, an inhibitor of topoisomerase I. This is then inactivated by glucuronidation by uridine diphosphate glucoronosyltransferase 1A1 (UGT1A1). The inhibition of topoisomerase I by the active metabolite SN-38 eventually leads to inhibition of both DNA replication and transcription.

Merrimack currently has six oncology therapeutics in clinical development, multiple product candidates in preclinical development and an active Systems Biology-driven discovery effort. 
  • Indication:
  • Description:
  • Target
  • Pancreatic Cancer (2nd line, 2 indications), Colorectal Cancer, Glioma
  • Nanotherapeutic
  • Encapsulated irinotecan
MM-398 is a nanotherapeutic consisting of the chemotherapuetic irinotecan, encapsulated in a liposomal sphere. MM-398 is designed to rely on the natural blood flow of the tumor to direct the therapy directly to the site of the cancer and minimize exposure to non-target cells.
MM-398 in the Clinic
MM-398 is being evaluated in clinical trials for its ability to treat tumors resistant to chemotherapy across multiple types of cancers, including pancreatic, lung, colorectal and glioma. The FDA and the European Medicines Agency granted MM-398 orphan drug designation in 2011 for the treatment of patients with metastatic pancreatic cancer who have previously failed treatment with the chemotherapy drug gemcitabine. Our Phase 3 study, NAPOLI-1 (NAnoliPOsomaL Irinotecan), is currently underway.

Anticancer agent – elacytarabin

Cytarabine is a cytosine derivative that is a common component of chemotherapy regimens for blood cancers such as acute myeloid leukaemia (AML), and because it can cross the blood–brain barrier, it is useful in the treatment of central nervous system lymphomas. However, the response is variable, and resistance commonly develops via multiple mechanisms. Its activity is dependent on the intracellular concentrations of the active phosphorylated form, and one of the main mechanisms of resistance involves the deficiency of the transporter molecule hENT1 that carries it into the cells. As a result, Clavis Pharma developed a lipophilic ester derivative, elacytarabine, whose cellular uptake is not hENT1-dependent.1

Cancer drug tested in pet dogs is now bound for human trials

Thanks to a new $2 million investment, a drug that spurs cancer cells to self-destruct while sparing healthy cells is on the road to human clinical trials. The compound, known as PAC-1, has so far proven safe and has promising anti-cancer effects in cell culture, in mouse models of cancer and in pet dogs with spontaneously occurring lymphomas and osteosarcomas.

If PAC-1 (pack one) makes it through the U.S. Food and Drug Administration’s Investigational New Drug review, the first human (Phase I) clinical trial of the drug will begin in mid-2014. The investor, who wishes to remain anonymous, has an option to invest another $2 million to take the drug into human trials. The clinical work will be conducted at the University of Illinois Cancer Center in Chicago.

University of Illinois chemistry professor Paul Hergenrother, left, and veterinary clinical medicine professor Tim Fan led a study of an anti-cancer compound in pet dogs that is now headed for human clinical trials.
PAC-1 (first procaspase activating compound) is a synthesized chemical compound that selectively induces apoptosis, or cell suicide, in cancerous cells. PAC-1 has shown good results in mouse models and is being further evaluated for use in humans. In 2010 a published study showed PAC-1 to be safe to research dogs, and a second study published later that same year reported that a PAC-1 derivative (called S-PAC-1) was well tolerated in a small Phase I Clinical Trial of pet dogs with lymphoma. Even at low doses of S-PAC-1, tumors regressed in 1/6 dogs, and the disease was stabilized (no additional tumor growth) in 3/6 dogs

Garlic in India



Garlic in India

Uses of Garlic in India
The ancient Indians had varying views on garlic; but, for the most part, it was considered to be highly beneficial to the body. Ancient Sanskrit writings, dating as far back as 5,000 years ago, described the healing properties of garlic. In fact, the ancient medical practice of Ayurveda, which is still practised today, promoted garlic as one of the most important herbs. It recommends garlic in over 100 formulations for treating stomach, liver, tumor, asthma and other similar problems.

The Charaka Samhita is the oldest surviving Ayurvedic text, dating back to 200 BCE to 200 CE (AD), and suggests using garlic for alleviating:

  • worms
  • piles
  • leukoderma
  • leprosy
  • epilepsy
  • heart disease
  • fainting
  • arthritis
  • rheumatism
  • chronic rhinitis
  • baldness.
 It was also included in the diet of nursing mothers to encourage milk secretion in nursing mothers and was hung to protect against evil spirits.

Other Ayurvedic teachings recommend garlic for:

  • arteriosclerosis
  • pain
  • cholera
  • dysentery
  • indigestion
  • constipation
  • appetite loss
  • fatigue
  • typhoid
  • tuberculosis
  • cough
  • fractures
It is also advocated for improving eyesight, intelligence, sexual debility, and impotency.

On the other hand, the ancient Indians believed garlic was a natural aphrodisiac that inspired lust and stimulated passions and, as a result, holy men, monks, widows, adolescents, and fasting persons were forbidden from consuming garlic. In addition, it was considered to be rajasic food; which meant it had unsettling effects on the body and devotees on the path to spiritual enlightenment were advised against eating it. The Buddists, Jains, Greeks and Romans also shared these sentiments; however, some believe the mild irritation garlic caused in the genitourinary tract may have resulted in its aphrodisiac and rajasic status.

Alexion’s Soliris® (eculizumab) Receives Orphan Drug Designation for the Treatment of Neuromyelitis Optica (NMO)

Structure of eculizumab. Eculizumab was engineered to reduce immunogenicity and eliminate effector function. Human IgG2 and IgG4 heavy-chain sequences were combined to form a hybrid constant region that is unable to bind Fc receptors or to activate the complement cascade. Eculizumab exhibits high affinity for human C5, effectively blocking its cleavage and downstream proinflammatory and cell lytic properties. Reprinted from Rother et al with permission.

Fort Mills Times
In a Phase 2 study presented at the 2012 annual meeting of the American Neurological Association (ANA), Soliris treatment was associated with a significant reduction in the frequency of relapses (recurring attacks) in patients with severe, relapsing ...

Eculizumab (INN and USAN; trade name Soliris) is a humanized monoclonal antibody that is a first-in-class terminal complement inhibitor and the first therapy approved for the treatment of paroxysmal nocturnal hemoglobinuria (PNH), a rare, progressive, and sometimes life-threatening disease characterized by excessive destruction of red blood cells (hemolysis). It costs £400,000 (US$600,000) per year per patient

Eculizumab also is the first agent approved for the treatment of atypical hemolytic uremic syndrome (aHUS), an ultra-rare genetic disease that causes abnormal blood clots to form in small blood vessels throughout the body, leading to kidney failure, damage to other vital organs and premature death.

In clinical trials in patients with PNH, eculizumab was associated with reductions in chronic hemolysis, thromboembolic events, and transfusion requirements, as well as improvements in PNH symptoms, quality of life, and survival.Clinical trials in patients with aHUS demonstrated inhibition of thrombotic microangiopathy (TMA),the formation of blood clots in small blood vessels throughout the body, including normalization of platelets and lactate dehydrogenase (LDH), as well as maintenance or improvement in renal function.

Eculizumab was discovered and developed by Alexion Pharmaceuticals and is manufactured by Alexion. It was approved by the United States Food and Drug Administration (FDA) on March 16, 2007 for the treatment of PNH, and on September 23, 2011 for the treatment of aHUS. It was approved by the European Medicines Agency for the treatment of PNH on June 20, 2007, and on November 24, 2011 for the treatment of aHUS. Eculizumab is currently being investigated as a potential treatment for other severe, ultra-rare disorders.

How many modes of action should an antibiotic have?

Structures of resistance-breaking derivatives of established antibiotic classes. Selected compounds are depicted that were recently launched or are currently in development. Ceftobiprole has increased affinity for PBP2a, a member of the target family of penicillin-binding proteins not affected by marketed β-lactams. Tigecycline, iclaprim, telithromycin, and telavancin make contacts to additional binding sites on their established targets or address additional targets. Structural elements responsible for the novel target interactions are marked bold. MCB-3681, TD-1792, and CBR-2092 are hybrid molecules, in which two pharmacophors from different antibiotic classes are attached by linkers. Linkers are marked bold

All antibiotics that have been successfully employed for decades as monotherapeutics in the treatment of bacterial infections rely on mechanisms of bacterial growth inhibition which are by far more complex than inhibition of a single enzyme. Such successful antibiotics have in common that they address several targets in parallel and/or that their targets are encoded by multiple genes. Such multiplicity of targets and of target genes has the advantage that the emergence of spontaneous target-related resistance is a comparatively slow process. Recently registered antibiotics and novel antibiotics in development are discussed in the light of this promising concept of antibacterial polypharmacology.
