POLICY:

HIV tropism testing, with either a phenotypic assay or population based V3 genotypic assay (via Sanger sequencing or V3 deep sequencing method), may be considered medically necessary for use in selecting patients for treatment with a HIV co-receptor antagonists, such as maraviroc (Selzentry®), when there is an immediate plan to prescribe a co-receptor antagonist.

HIV tropism testing without immediate plans to prescribe HIV co-receptor antagonists, such as maraviroc (Selzentry®), is considered investigational. 

Repeat HIV tropism testing during co-receptor antagonist treatment or after failure with co-receptor antagonists is considered investigational.

HIV tropism testing to predict disease progression (irrespective of co-receptor antagonist treatment) is considered investigational.

DESCRIPTION OF PROCEDURE OR SERVICE:

HIV tropism testing can determine the predominant co-receptor protein used by the human immunodeficiency virus (HIV) to infect target cells. Tropism testing can help select patients for treatment with HIV co-receptor antagonists, such as maraviroc (Selzentry®), which selectively binds to the CCR5 co-receptor and thus is only effective for use against CCR5-tropic HIV-1.

HIV

The human immunodeficiency virus (HIV-1), which causes acquired immunodeficiency syndrome, uses co-receptor proteins (either CCR5 or CXCR4) on the surface of target cells to enter and infect the cells. The most commonly transmitted strains of HIV-1 bind to CCR5 and are said to have “tropism” for CCR5-expressing cells. Dual or mixed (D/M) tropic viruses can bind to either receptor type. CXCR4-tropic virus is associated with immunosuppression and later stages of disease. Co-receptor antagonists have been designed to interfere with the interaction between HIV-1 and its co-receptors.

HIV Co-receptor Antagonists

Maraviroc (Selzentry®) is a selective, slowly reversible, small-molecule antagonist of the interaction between human cell surface CCR5 and HIV-1 gp120, necessary for HIV-1 cell infection. Blocking this interaction prevents CCR5-tropic HIV-1 entry into cells. CXCR4-tropic HIV-1 entry is not prevented. The currently-approved maraviroc (Selzentry®) label indicates that the drug is indicated for combination antiretroviral treatment for adults infected with only CCR5-tropic HIV-1, without discussion of the presence of viral replication.

Other HIV co-receptor antagonists are in the drug development pipeline, such as cenicriviroc (CVC) is a small-molecule antagonist of both CCR5 and CCR2, allowing it to function as an entry inhibitor which prevents the virus from entering into a human cell. The CCR2 receptor may have an anti-inflammatory effect. This drug has not received FDA approval for use in HIV.

Phenotype testing

The first method available and most widely recommended tropism testing is phenotype testing. Phenotypic resistance testing directly measures relative in vitro susceptibility to a drug. Trofile® is a phenotypic viral RNA assay that can identify CCR5 antagonist candidates. Commercially available HIV drug susceptibility and resistance tests include phenotypic tests (e.g., PhenoSense HIV, and Virco Antivirogram).

Genotype testing

Tropism testing is based on sequencing the third variable (V3) loop of the HIV glycoprotein 120 gene, because the V3 loop interacts with the HIV co-receptor, and mutations in V3 are associated with measurable changes in HIV tropism. Genotypic resistance testing depends on the ability to interpret such sequence data. Tropism assignment is derived from the sequence data using a bio-informatic algorithm such as geno2pheno. The geno2pheno system has been designed to support the interpretation of sequence data resulting from genotypic resistance tests. Commercially available HIV drug susceptibility and resistance tests include genotypic tests (e.g., ABI Gene Sequencing; TrueGene HIV Genotyping GeneKit; HIV-1 GeneSeek Test; Murex LiPA HIV-1 RT; ViroSeq Genotyping System, and Affymetrix GeneChip HIV PRT Assay). 

KEY POINTS:

This policy was updated with the literature available through December 06, 2024. 

Summary of Evidence

For individuals who have HIV infection who are being considered for HIV co-receptor antagonist therapy who receive HIV tropism testing, the evidence includes RCTs. Relevant outcomes are overall survival, disease-specific survival, morbid events, quality of life, hospitalizations, medication use, and treatment-related morbidity. RCTs on treatment-naive and treatment-experienced HIV-infected patients have provided evidence that selection of candidates for HIV co-receptor antagonist therapy using HIV tropism testing results in higher rates of treatment success compared with HIV co-receptor antagonist therapy without HIV tropism testing. The evidence is sufficient to determine that the technology results in a meaningful improvement in the net health outcome.

For individuals with HIV infection receiving HIV co-receptor antagonist therapy or who have failed co-receptor antagonist therapy who receive HIV tropism testing, the evidence includes post hoc analysis of RCTs and observational studies. Relevant outcomes are overall survival, disease-specific survival, morbid events, quality of life, hospitalizations, medication use, and treatment-related mortality and morbidity. Current evidence does not indicate improved outcomes with additional tropism monitoring during treatment. The evidence is insufficient to determine that the technology results in a meaningful improvement in the net health outcome.

For individuals with HIV infection who are undergoing tests to predict disease progression who receive HIV tropism testing, the evidence includes observational studies. Relevant outcomes are overall survival, disease-specific survival, morbid events, quality of life, hospitalizations, and medication use. Current evidence is inconsistent in proving if HIV tropism testing independently predicts disease progression among HIV-infected patients. The evidence is insufficient to determine that the technology results in a meaningful improvement in the net health outcome.

Practice Guidelines and Position Statements

HIV Medicine Association of the Infectious Disease society of North America

The HIV Medicine Association of the Infectious Disease Society of North America released updated guidelines on the on the management of persons infected with HIV in 2020. These guidelines state that tropism testing should be performed if the use of a CCR5 antagonist is being considered (strong recommendation, high quality evidence). The guidelines also state that “routine tropism testing is not recommended prior to initiation of other regimens because of cost and lack of demonstrated benefit.” The guidelines do not specify the preferred method of tropism testing.

European Consensus Group

The European Consensus Group on clinical management of tropism testing states that tropism testing is indicated for patients who fail treatment or have unacceptable toxicity and a CCR5 inhibitor is being considered. In the absence of evidence, the group provides no guidance regarding tropism testing for newly diagnosed patients whose immediate treatment plan does not include a CCR5 inhibitor. In the absence of adequate data, the group could provide no guidance regarding the question of testing treatment-naïve patients prior to the start of a regimen not including a CCR5 inhibitor, in anticipation of need for a fast change to a CCR5 inhibitor due to the toxicity of the initial treatment regimen. For patients with a plasma HIV RNA load >1,000 copies/mL, tropism testing can be done by Trofile® or by population genotypic analysis of the V3 loop, indicating for both a moderate level of evidence based on well-designed, nonrandomized trials or cohort studies with long-term clinical outcomes. For patients with a plasma HIV RNA load <1,000 copies/mL, genotyping is the preferred method.

Department of Health and Human Services (DHHS)

In 2018, the United States Department of Health and Human Services published guidelines for the use of antiretroviral agents in adults and adolescents living with HIV. They recommend the use of co-receptor tropism assays (including a phenotypic tropism assay) in clinical practice as follows:

• A co-receptor tropism assay should be performed whenever the use of a CCR5 co-receptor antagonist is being considered (Level of Evidence AI);
• Co-receptor tropism testing is also recommended for patients who exhibit virologic failure on a CCR5 antagonist (Level of Evidence BIII);
• A phenotypic tropism assay is preferred to determine HIV-1 co-receptor usage (Level of Evidence A1);
• A proviral DNA tropism assay can be utilized for patients with undetectable HIV-1 RNA when CCR5 antagonist is considered for use in a new regimen (e.g., as part of a regimen switch or simplification) (Level of Evidence BII).

Note:

Rating of Recommendations: A = Strong; B = Moderate; C = Optional;

Rating of Evidence: I = data from randomized controlled trials; II = data from well-designed nonrandomized trials or observational cohort studies with long-term clinical outcomes; III = expert opinion.

Infectious Diseases Society of America

In 2020, The Infectious Diseases Society of America published guidelines that state “tropism testing should be done before starting any CCR5 antagonist. Also, patients who exhibit virologic failure while taking a CCR5 antagonist may also be considered for tropism testing”.

U.S. Preventive Services Task Force Recommendations

Not applicable.

APPROVED BY GOVERNING BODIES:

The purpose of the following information is to provide reference material. Inclusion does not imply endorsement or alignment with the evidence review conclusions.

The FDA-approved full prescribing information for maraviroc (Selzentry®) states that “Tropism testing must be conducted with a highly sensitive and specific tropism assay that has demonstrated the ability to identify patients appropriate for [maraviroc (Selzentry®)] use.”

Currently-available HIV tropism tests are performed as laboratory developed tests (LDTs). Clinical laboratories may develop and validate tests in-house and market them as a laboratory service; LDTs must meet the general regulatory standards of the Clinical Laboratories Improvement Act (CLIA). HIV tropism tests are is available under the auspices of the Clinical Laboratory Improvement Amendments. Laboratories that offer laboratory-developed tests must be licensed by the Clinical Laboratory Improvement Amendments for high-complexity testing. To date, the FDA has chosen not to require any regulatory review of this test.

This medical policy is not an authorization, certification, explanation of benefits, or a contract. Eligibility and benefits are determined on a case-by-case basis according to the terms of the member’s plan in effect as of the date services are rendered. All medical policies are based on (i) research of current medical literature and (ii) review of common medical practices in the treatment and diagnosis of disease as of the date hereof. Physicians and other providers are solely responsible for all aspects of medical care and treatment, including the type, quality, and levels of care and treatment.

This policy is intended to be used for adjudication of claims (including pre-admission certification, pre-determinations, and pre-procedure review) in Blue Cross and Blue Shield’s administration of plan contracts.

The plan does not approve or deny procedures, services, testing, or equipment for our members. Our decisions concern coverage only. The decision of whether or not to have a certain test, treatment or procedure is one made between the physician and his/her patient. The plan administers benefits based on the member’s contract and corporate medical policies. Physicians should always exercise their best medical judgment in providing the care they feel is most appropriate for their patients. Needed care should not be delayed or refused because of a coverage determination.

As a general rule, benefits are payable under health plans only in cases of medical necessity and only if services or supplies are not investigational, provided the customer group contracts have such coverage.

The following Association Technology Evaluation Criteria must be met for a service/supply to be considered for coverage:

1. The technology must have final approval from the appropriate government regulatory bodies;
2. The scientific evidence must permit conclusions concerning the effect of the technology on health outcomes;
3. The technology must improve the net health outcome;
4. The technology must be as beneficial as any established alternatives;
5. The improvement must be attainable outside the investigational setting.

Medical Necessity means that health care services (e.g., procedures, treatments, supplies, devices, equipment, facilities or drugs) that a physician, exercising prudent clinical judgment, would provide to a patient for the purpose of preventing, evaluating, diagnosing or treating an illness, injury or disease or its symptoms, and that are:

1. In accordance with generally accepted standards of medical practice; and
2. Clinically appropriate in terms of type, frequency, extent, site and duration and considered effective for the patient’s illness, injury or disease; and
3. Not primarily for the convenience of the patient, physician or other health care provider; and
4. Not more costly than an alternative service or sequence of services at least as likely to produce equivalent therapeutic or diagnostic results as to the diagnosis or treatment of that patient’s illness, injury or disease
