Common anti-allergy drugs may treat deadly blood clots: study

Common anti-allergy medicines could prove to be an effective treatment for potentially fatal blood clots in the legs, a study has claimed.

The research by the University of Birmingham in the UK could lead to new treatments that prevent deep vein thrombosis (DVT), a blood clot that develops within a deep vein in the body, usually in the leg, and causes swelling, aching and difficulty walking.

It can be caused by prolonged periods of immobility, such as after surgery or during a long flight.

If the clot becomes dislodged it can travel to the lungs and block a blood vessel. This is known as a pulmonary embolism (PE). An estimated 30 per cent of PEs cause sudden death.

The team discovered that mice genetically depleted of mast cells, a type of immune cells, are protected from developing DVT.

The current treatments for DVT include anti-clotting drugs such as heparin and warfarin. These drugs are relatively effective but put patients at increased risk of bleeding.

ICH GCP requires EC members to be independent of investigator and sponsor to avoid conflicts of interest

Can an Ethics Committee member e.g. layman/chairman or anyone in the committee participate in the trial as a subject? Vidya If an Ethics Committee member becomes a trial subject on a trial that he/she was involved in approving then there has been a major conflict of interest. The following situations need to be considered: ● IEC member reviews study without any prior knowledge of the study, votes, and then afterwards is approached by clinical research team to participate. Possibly this is OK but the member should no longer be part of the IEC that reviews that study. This will be difficult in practice, so therefore it is not advisable. ● IEC member already knows about the study and is voting in order to be able to participate. This is clearly not acceptable and made worse if there is additional financial incentive for the study (e.g. volunteer study). ICH GCP requires Ethics Committee members to be independent of the investigator and the sponsor to avoid confl...

BE guidelines regarding investigator

BE guidelines recommend investigator should possess appropriate medical qualification, experience for conducting pharmacokinetic studies Can chairperson of EC directly write to sponsor to clarify some of the queries of clinical trial raised in EC meeting? Dr. Sreevatsa Please see an extract from FDA's comment on IRB-sponsor relationship. The interrelationship and interaction between the research sponsor (e.g., drug, biologic and device manufacturers), the clinical investigator and the Institutional Review Board (IRB) may be very complex. The regulations do not prohibit direct sponsor-IRB contacts, although, the sponsor-IRB interaction customarily occurs through the investigator who conducts the clinical study. The clinical investigator generally provides the communication link between the IRB and the sponsor. Such linkage is agreed to by the sponsors and investigators when they sign forms FDA-1571 and FDA-1572, respectively, for drug and biologic studies or a...

Isotretinoin in India: A tragedy in the offing

Isotretinoin in India: A tragedy in the offing Wednesday, March 28, 2007 08:00 IST  Seema Thakral Isotretinoin is the drug of choice for severe calcitrant cystic acne vulgaris, which often causes scarring and depression from disfigurement. Isotretinoin has been called "the greatest medical advance of the 1980's." A majority of patients with acne are permanently cleared after a four to five months course of treatment. It has also been used off-label for a variety of oncology uses including: cervical cancer, head and neck cancer, squamous cell cancer of the skin, juvenile chronic myelogenous leukemia (CML), and neuroblastoma. However, the drug is a proved teratogen and carries a significant risk of birth defects, if it taken during pregnancy. Birth defects, which have been documented following isotretinoin exposure include abnormalities of the face, eyes, ears, skull, central nervous system, cardiovascular system, and thymus and parathyroid glands. There is an increased ris...
