Nuclear Medicine Division
• The Science we do
• Our people power
• Our infrastructure
• Our goals
• A canadian vision
Mission• The mission of TRIUMF Nuclear Medicine Division is to perform research
and development for the production of radioisotopes with potential applications in physical and biomedical research, to prepare certain commercially unavailable radioisotopes for distribution to researchers, to design and synthesize radiotracers with optimal properties for imaging biological targets and to develop novel tracer imaging systems.
• In conjunction with this mission, the group also performs service irradiations and explores opportunities for new radioisotopes applications.
• The program is focused very strongly on making use of the unique particle beams from the TRIUMF accelerators and of its radioisotope production facilities.
• The group acts as a support group for the research community in the use of modern tools associated with the production and detection of radiotracers produced at TRIUMF and as a consulting team to potential commercial providers of isotopes or other such technologies as employed by the program, under TRIUMF licensing agreements.
• The program includes also projects making use of particles beams directly ( like proton therapy , proton irradiations,..)

Science with academia: UBC
• Pacific Parkinson Research Centre
• UBC Psychiatry
UBC PET Program• Complications of PD: Inverse relationship between
dopamine (DAT) expression and dopamine turnover (published) and as a corollary, evidence that reduced DAT expression is associated with increased risk of dyskinesias (Neurology, under revision).
• No difference between depressed and non-depressed PD subjects in amphetamine-induced DA release.
• Mood disorders: Preliminary results suggest that increased dopaminergic activity in mania is due to reduced dopamine transporter with consequent failure of uptake of dopamine into presynaptic neuron.
Continued• Placebo effect: Placebo-induced DA release in both
the putamen and the ventral striatum was seen only when subjects were told there was a 75% probability of receiving active drug (levodopa) and not at 25, 50 or 100%.
• Studies on the role of conditioning are underway and suggest that, as expected, administration of active drug in a ritualized setting leads to enhancement of the behavioural response to a placebo administered in the same setting.
• Gambling: A pilot study of hedonic stimuli (flavoured drinks) to elicit DA release.

Science with Health Institutes: BCCA
• LS93 18F-Fluoroestradiol PET/CT guided fulvestrant therapy for patients with recurrent or metastatic breast cancer
F.Benard (BCCA),M.Adam(TRIUMF),M.Vulcovic(BCCA) – Assess the potential of [18F]FES PET/CT imaging to predict the benefit of administering
fulvestrant in women with recurrent or metastastic breast cancer who have progressed following treatment with aromatase inhibitors and/or tamoxifen.
– 1) High [18F]FES uptake at the baseline scan in known tumor sites is predictive of clinical benefit to fulvestrant therapy, while low [18F]FES uptake in some or all active tumor sites is predictive of fulvestrant therapy failure
– 2) Limited blockage/downregulation of [18F]FES uptake after 3 months of fulvestrant therapy is predictive of treatment failure.
– To assess these hypotheses we will conduct a prospective phase II cohort study to determine whether [18F]FES uptake at baseline and/or after reaching pharmacological steady-state of fulvestrant therapy can predict clinical benefit to this drug.
– The accrual plan is 100 patients over 2 years.
Science (BCCA)
• FES is being developed at TRIUMF by Milan Vuckovic and M.Adam’s team for testing the quality of the product.
• The full Trial has been funded by NIH and should proceed at BCCA when their production facility will be operational.
Science with Health Institutes: BCCA
• LS 74: Principal investigators D.Yapp (BCCA) and Mike Adam(TRIUMF)
• EF5 Marking agent for tumor Hypoxia in Lung cancer
• Produced by M.ADAM at TRIUMF• 3 Patients accrued so far for pre and post
chemio therapy treatment scanning with EF5 produced at TRIUMF
• Evaluation after 6 Patients • Study funded by Roche
Science with Nordion
• LS 85 and LS90 With MDS-Nordion Vancouver– NSERC Collaborative Research and Development Award (3Year/$100K/y)
with matching funds from MDS Nordion– UBC Chemistry (C.Orvig), TRIUMF (M.Adam), MDS-Nordion ( D.Wester, C
Ferreria)
• Enabling Technologies for Metallic Radioisotopes in Nuclear Medicine (LS90)– Investigate the design possibilities for target-specific bioconjugates for 68Ga
and/or 111In as novel brain, heart, tumour and cardiovascular plaque imaging agents
– provide a new generation of compounds for radioimaging – develop new chelation chemistry of Ga and In that will lay the groundwork for
further advances in molecular imaging. – Post doc and Student hired

The tools: Infrastructure
• Tr13 cyclotron• “old” Radiochemistry laboratories• New MHESA R/D laboratory with Nordion• Pet imaging centre at UBC (director
V.Sossi)– HRRT– Advance (GE) whole body – MicroPET
• Future large Animal imaging laboratory
Work planShort term ( 2009-2010):
• Consolidate existing radiotracers production and optimize their yields, especially for 11C based tracers.
– Understand the production yield difference of the East versus West port of the TR13.– Understand the production yield for 11C from niobium targets ( Nb tube vs block)– Optimize the conversion efficiency for CH4 to methyliodide– Evaluate the production of CO2- MEI vs CH4-MEI
• QA metric: delivering more than 95% of scheduled scans • Recommission the “ADVANCE” GE camera
– Renovation– Calibration– MRO support
• Initiate R/D program associated with the CDR grant on metallic tracers – Develop a the RCRC MHESA laboratory.– Prepare second CR proposal with MDS Nordion
• Integrate proton therapy and proton irradiation into the division• Prepare a plan for extending the support provided to the BCCA nuclear medicine group for the
production 18F at TRIUMF during the period before and after installation of their own production facilities.
• 6) GMP issues, may become 0): Design new facilities for New building or renovate Chemistry annex facilities. This will depend on the success of the CFI proposal and or the provincial government funding for the new building
Work Plan
Mid Term: ( 2010-2012)• 1) Start building a national network with or
without CFI support.• 2) Launch new collaborations:
– Cross cancer(Edmonton),BCCA ,TRIUMF– Calgary, BCCA, TRIUMF.– MDS Nordion
• 3) Explore new avenue with Genome BC / GEHealthcare / P-Cure/U.Calgary
• 4) Establish an imaging centre at the UBC animal care facility
Infrastructure requirements
• Commission TR13 enclosure– Stop gap measure, before enclosing the cyclotron in a proper vault in a
new Nuclear Medicine building.
• Commission Advance camera – More reliable long term full body scanning ability
• Build new RCRC Lab – State of art radiochemistry lab with new nuclear ventilation and hot
cells for R&D
• Exploit Microfluidics technologies– Shorter reaction time and better specific activities
