1. Guideline news – local and national


New SIGN guidelines on colorectal cancer

The Scottish Intercollegiate Guidelines Network
(SIGN) have recently published guidelines on
diagnosis and management of colorectal cancer.
This guidance covers primary care and referral,
surgery, pathology, treatment with chemotherapy and
radiotherapy, and follow up. The guideline can be
accessed at www.sign.ac.uk

 
New NICE multi-technology appraisals:

Health improvement Scotland has advised that the
following advice is applicable in NHS Scotland.

TA241 Dasatinib, high-dose imatinib and nilotinib
for the treatment of imatinib-resistant chronic
myeloid leukaemia (CML)

The Scottish Medicines Consortium (SMC) has
previously issued guidance to NHSScotland on the
use of dasatinib and nilotinib in this indication
(370/07, 440/08). There is a material difference
between the NICE and SMC advice. High-dose
imatinib has not been assessed by SMC for use in
chronic myeloid leukaemia. The NICE MTA
guidance supersedes the SMC advice.

The Regional Prescribing Advisory Subgroup have
considered this advice and will be issuing a revised
Clinical Management Guideline for CML to local
boards in the near future.

TA242 Colorectal cancer (metastatic) 2nd line –
cetuximab, bevacizumab and panitumomab.

The Scottish Medicines Consortium (SMC) has
previously issued guidance to NHSScotland on the
use of cetuximab, bevacizumab and panitumumab in
this indication (155/05, 469/08, 486/08). This NICE
MTA guidance supersedes the SMC advice. There is
no material difference between the recommendations
of NICE and SMC. Therefore there are no implications for local practice.

TA243 Rituximab for first line treatment of stage III-IV follicular lymphoma

The recommendations replace the recommendations in TA110 relating to the use of rituximab in this indication. The Scottish Medicines Consortium (SMC) has previously issued guidance to NHSScotland on the use of rituximab in this indication (493/08). The recommendations of NICE and SMC are consistent. Therefore there are no implications for local practice.

West of Scotland Guidelines on the use of bisphosphonates in cancer patients

The recent WoSCAN guidelines have now been accepted by NHSGGC. The full guidelines and patient information leaflet can be accessed on the WoSCAN intranet site
www.intranet.woscan.scot.nhs.uk.

The main changes from the previous version of the guideline are:

  • Zoledronic acid recommended as first line in multiple myeloma (was previously recommended as 2nd line)
  • More detailed information on dose / administration modifications in patients with renal impairment
  • More information on bisphosphonate related osteonecrosis of the jaw
  • Calcium supplementation advice
  • A statement relating to the most recent advice from the MHRA regarding atypical femoral fractures
  • A patient information leaflet has been developed for cancer patients receiving bisphosphonates

2. Drug Safety Update

Domperidone safety communication

In December 2011 a safety communication was issued by manufacturers of domperidone (in collaboration with MHRA) highlighting new information regarding cardiac risks associated with domperidone. Some epidemiological studies have shown that domperidone may be associated with an increased risk of serious ventricular arrhythmias including sudden cardiac death. The risks may be higher in patients over 60 years and in those receiving daily doses above 30mg. Domperidone should be avoided in patients taking concomitant medication known to prolong QT.

  • The West of Scotland Cancer Network are revising their guidelines for managing chemotherapy induced nausea and vomiting and will no longer recommend the use of domperidone
  • The updated anti-emetic guidelines will be issued in the near future. In the meantime prescribers are asked to take notice of this safety advice and consider alternative anti-emetics

It is recognised that a variety of drugs are known to prolong the QT interval. The risk of QT prolongation is determined by underlying patient risk factors, the risk category of the drug involved and the concomitant use of drugs which either carry an additional risk of QT prolongation or increase plasma levels of drugs known to prolong QT (e.g. CYP3A4 inhibitors). Further practical advice for dealing with this prescribing issue is being developed within NHSGGC.

SmPC Changes

(Full details available at www.medicines.org.uk/emc)

Imatinib (Glivec®)

The summary of product characteristics has recently been updated to include new advice for use of imatinib in patients
with renal dysfunction or on dialysis, and also new advice on drug interactions. Caution is advised when co-administering drugs that are CYP3A4 inhibitors (eg ketoconazole), which may increase imatinib plasma concentrations, and result in toxicity. In addition, caution is advised when co-administering CYP3A4 inducers (eg. dexamethasone, phenytoin) which have the potential to decrease exposure to imatinib and increase risk of therapeutic failure.

Dasatinib (Sprycel®)

The summary of product characteristics for dasatinib as recently been updated.  Under "Important adverse
reactions” there is new advice on management of myelosuppression, which occurs more frequently with advanced phase CML or Ph+ ALL than in chronic phase CML. Advice is given on frequency of blood count monitoring for imatinib resistant or intolerant patients and in patients with newly diagnosed chronic phase CML. Guidance is given regarding management of myelosuppression by temporary interruption of therapy or dose reduction.

 

3. MHRA Yellow card reporting scheme

Prescribers are reminded of the importance of reporting adverse drug reactions to the MHRA via the yellow card reporting scheme.  This can be done at http://yellowcard.mhra.gov.uk/

The Yellow Card Scheme is vital in helping the MHRA monitor the safety of the medicines and vaccines that are on the market. Even if it is only a suspicion that a medicine or combination of medicines has caused a side effect, this should be reported.

Established therapy

Regardless of how long a drug has been on the market, any serious adverse event thought to be associated with a medicine or vaccine should be reported. Serious reactions are those that are fatal, life-threatening, incapacitating or those that require hospitalisation (or prolong stay in hospitalised patients); such reactions range from anaphylaxis to an effect on fertility. For established drugs (those without black-triangle status), there is no need to report well-known non-serious adverse effects (e.g. low grade fever with vaccines or constipation with opioid analgesics).

New therapies

The MHRA’s surveillance of adverse effects of new medicines is more intensive; for such medicines, an inverted black triangle is shown against the name of the medicine in the Summary of Product Characteristics (SmPC) and in compendia such as the British National Formulary (BNF) and MIMS.  Any adverse effect suspected to be associated with black-triangle medicines should be reported on a Yellow Card. Medicines are under intensive surveillance typically for a couple of years, after which the black-triangle denotation is removed. However, if there is doubt about the risk profile of a medicine then the black triangle is retained longer (or sometimes reinstated).

All suspected adverse reactions in children should be reported, whether from established medicines or newly launch
from licensed use.

4. Recent Clinical Audit Highlights

A medicines use evaluation of sunitinib for renal cell carcinoma in the West of Scotland

A medicines use evaluation was recently carried out to determine treatment response, tolerability and compliance with the West of Scotland protocol.

The results have now been analysed and provide useful information on:

  • duration of therapy 
  • frequency of monitoring for adverse effects
  • incidence of toxicities
  • dose adjustments/omissions
  • response to treatment
  • reasons for stopping

A key finding was the importance of monitoring for toxicities at every cycle and ensuring adverse effects
are managed promptly in order to minimise reductions in dose intensity. A further finding was the inconsistent documentation of toxicities. The results have also been compared with the pivotal trial for sunitinib in terms of duration of therapy and tolerability. For more details please contact Dr Nicholas MacLeod (nicholas.macleod@ggc.scot.nhs.uk) or Jennifer Laskey (jennifer.laskey@ggc.scot.nhs.uk).
