Ontario Health Policy Research
• Ontario’s Healthcare Data
– Ontario has ‘universal’ healthcare coverage
– Databases record healthcare transactions for administrative
purposes
– Data related to healthcare stored in separate but linkable datasets:
physician claims, hospitalizations, drug utilization, emergency
department visits
• Institute for Clinical Evaluative Sciences
– ICES is a non-profit research organization established in 1992
– Funded by the Ontario Ministry of Health and granting agencies
– Over 250 faculty and staff
– Stores many of Ontario’s healthcare administrative databases for
research purposes: databases are linked
The ODPRN
• Ontario-wide, independent drug policy research group
established in 2008
• Primary Objective
– Provide high quality, relevant drug research to OPDP in a
timely manner on an as-needed basis
• Funded by grants from the Ontario Ministry of Health and
Long-Term Care
Goal:
Bridge clinical researchers with drug policy decision-makers
to advance evidence-informed decision making
The ODPRN Structure

Objectives of Drug Class Reviews
• Pragmatic formulary modernization research to
provide the Ministry of Health and Long-Term
Care with recommendations for evidenceinformed drug policies.
• Core Principles:
– Scientific rigor
– Timeliness
– Policy relevance
Principles of Drug Class Reviews
• Conduct reviews that address the needs of patients,
health-care providers and policy-makers
• Provide basis for evidence-informed policies that
incorporate societal values and beliefs
• May lead to recommendations regarding:
–
–
–
–
–
Expansion of access to drugs on the formulary
Revision or restriction of access to drugs
No change to current listing status
Alternative drug reimbursement models
Education of prescribers regarding appropriate prescribing

Testosterone Replacement
Therapies (TRT)
Why review TRTs?
• Currently under LU
– Is this the best way to list on the formulary?
• Safety concerns identified (e.g., CV events)
• Lack of large-scale, long-term clinical trials
• Rise in utilization of TRT products in
Ontario, especially topical products in men

Summary
EFFICACY AND SAFETY
50
Some high level thoughts on
results of the NMA analysis
•
Several of the testosterone replacement therapies were associated
with a substantive increase in serum testosterone levels at 3 months.
•
No significant effects in quality of life, erectile dysfunction, libido, or
depression were identified.
•
In head-to-head comparisons:
– Androgel 1% (100 mg/d) was associated with more favourable
serum testosterone levels at 3 months than the other TRTs.
– Andriol (120 mg/d) was associated with less favourable serum
testosterone levels at 3 months than the other TRTs.
– Few significant differences among the TRTs for quality of life,
erectile dysfunction, libido, and depression.
51
Some high level thoughts on
results of the NMA analysis
•
Serious adverse events – T gel (199) v. placebo (195): OR 1.61
(95% CI 0.77–3.36).
•
Other
•
•
•
•
•
Skin reactions ranged from mild irritation to intense edema and
blistering; were primarily associated with topical preparations
safety data were limited:
CV death – 4 deaths in T gel group and zero in placebo.
MI - 2 events in T gel group and 1 in placebo.
Stroke – 1 event in T gel group and 1 in the placebo.
Prostate cancer - 2 cases in T gel group and 1 in placebo; 4 in
testosterone IM and 5 in placebo.
• Heart disease (1 study) – 2 cases in testosterone and 4 in
placebo.

Pharmacoeconomics Unit
Testosterone Replacement Therapy
Doug Coyle, Karen M. Lee, Kelley-Anne Sabarre, Kylie Tingley
Pharmacoeconomic Unit within
ODPRN
• Coordinated by researchers based at the
University of Ottawa and CADTH
– Potential for involvement of researchers
outside of core group
• Objective
– To generate applied, policy-oriented
pharmacoeconomic models
Roles within each class review
Clarifying and refining study questions
Drafting of Health Economics Proposal
Review of economic literature
Development of economic model and
population with clinical review data
• Modeling of alternate reimbursement
strategies
•
•
•
•
– Reimbursement Based Economics
Reimbursement Based Economics
• Novel, pragmatic approach to pharmacoeconomics
• Identify the optimal reimbursement model considering
budget impact and cost effectiveness as criteria.
– e.g. bundling strategies, price caps, risk-sharing, CED.
• Comprehensive budget impact analysis plus traditional
pharmacoeconomic models where relevant .
– Incorporate market dynamics of different drug policy scenarios.
• Market expansion, cannibalization, and companion drug utilization effects
Research Questions: Testosterone
Replacement Therapy
1)
What is the current evidence for the
cost-effectiveness of testosterone replacement therapy
(TRT) in all clinical areas where it is indicated?
2)
What is the economic impact of alternative policies for
reimbursing testosterone replacement therapies?
#
Given the broad nature of the decision question, a de novo economic
evaluation to assess the value for money for testosterone replacement
therapy in all clinical areas where it is indicated was not feasible.
Methods
• Systematic Review of Published Literature
– Focused on strength and quality of evidence, and
generalizability of the reports to OPDP
• Reimbursement Based Economic Assessment
– Developed an applied, policy-oriented economic model
– Estimated TRT expenditure for next three years
– Identified alternative approaches to reimbursement of
TRT
– Estimated TRT expenditure for each reimbursement
scenario
Reimbursement Strategies
• Considered three possible strategies
– Move all products (all dosage forms) to EAP
– Move only topical forms to EAP
– Move both topical and oral forms to EAP
• Assumptions
– All tests are positive, so if tested, then patients will be eligible under EAP.
– There will be no extra testing with EAP.
– Overall rates for selective moving of products to EAP based on provinces
with similar listing status.
– The relative use between products not moved to EAP will remain as is.
• Sensitivity analyses conducted to test impact of assumptions
Results - Review of Literature
• 1 study included in review; linked to industry
(Arver et al. (2014)
• Study favored industry’s product
• Limitations
– Efficacy data based on assumption of 100% response
– Treatment considered (testosterone undecanoate) not
available in Canada

Conclusions (1)
• Given the lack of evidence and concerns with
the methodological quality of the available study,
no inferences over the cost effectiveness of
testosterone replacement therapy can be made.
• As a result, the reimbursement based economic
assessment focussed solely on the budget
impact of alternative reimbursement scenarios
for testosterone replacement therapy.
Conclusions (2)
• In 2013, total OPDP expenditure on TRT
was $8.3 million.
• Without any change in reimbursement in
TRT, TRT expenditure is expected to
surpass $12 million by 2016 ($5 million for
patients <65 years and $7 million for
patients ≥ 65 years).
• Moving products to EAP will reduce TRT

Key findings
Diagnosis of
hypogonadism can
be complex
• “While we are potentially trying to increase access for
patients who truly need it, we gotta think, if we flood the
market with this product, what are the long term
consequences? We really have no idea, there is no study
that is over 3 years of testosterone supplement.”- Urologist
Multiple factors
influence
formulation choices
• “One of the important issues is cost. Some of them are very
expensive [especially if] he requires large amounts of
testosterone, others are less expensive. Most of them are
covered by plans but sometimes you have patients who are
not covered by any plan”- Urologist
Access to TRT
products
• “I know when I was talking to another friend of
mine, when he wanted it I think he got it without
the test, but that’s because he put up a big stink
about it.”- Patient

Listing of TRTs in Ontario
• LU listing (Code 397):
For male patients with confirmed low morning serum
testosterone levels associated with documented,
symptomatic hypothalamic, pituitary or testicular
disease, or in HIV-infected patients.
Note: Older males with nonspecific symptoms of
fatigue, malaise, depression who have a low normal
random testosterone level do not satisfy these criteria.
– LU Authorization Period: 1 year
Pharmacoepidemiology:
Total utilization of TRT dispensed in Canada
Rate of testosterone use among public drug
plan beneficiaries in 2012
Provincial rate of topical TRT use among
public drug plan beneficiaries 65+

Documented diagnosis of
hypogonadism
Comment
10-17% of patients had
diagnosis of hypogonadism
(testicular dysfunction or
pituitary gland disorder) OR
HIV-infected
Testosterone level prior to
initiating therapy
1/3 new TRT users (over age
65) had NO lab tests in year
prior to 1st prescription
Limitations
• NPDUIS holdings not available for Quebec,
Newfoundland & Labrador or the Territories
• Hypogonadism is not well captured in administrative data
– Therefore sensitivity and specificity are unknown
– Definition was based on:
1. Physician visit with testicular dysfunction indicated in past 3
years (specific definition)
2. Physician visit with testicular dysfunction or pituitary gland
disorders indicated in past 3 years (broader definition)
3. Lab test for testosterone levels in the past year among new
users
