Subsequently, it was replaced in clinical practice with newer, more potent, and better-tolerated medications. Nelfinavir is administered without a pharmacokinetic booster and has a relatively low potency and low genetic barrier to resistance. Fortunately, most patients who developed drug resistance to nelfinavir respond to at least one of the newer HIV protease inhibitors. Nelfinavir is no longer recommended for use in antiretroviral therapy regimens and patients taking this agent should switch to a more current option. Key Clinical Trials In an early trial that compared nelfinavir to full-dose ritonavir plus background NRTIs for patients with advanced HIV (CD4 count below 200 cells/mm3), progression to AIDS or death was similar between the two arms, though more patients in the ritonavir arm discontinued treatment [CPCRA 042]. Multiple subsequent trials (some in treatment-naïve persons and some in treatment-experienced) showed that the efficacy of nelfinavir was inferior relative to other anchor antiretroviral agents, including fosamprenavir [NEAT], lopinavir- ritonavir [M98-863], and efavirenz [ACTG 384 and ACTG 388]. Resistance For a listing of the most common clinically significant mutations associated with nelfinavir (NFV) resistance, see the PI Resistance Notes on the Stanford University HIV Drug Resistance Database.

Batch specific analytical results are provided on each certificate of analysis. Laboratory Procedures Fosamprenavir (calcium salt) is supplied as a crystalline solid. A stock solution may be made by dissolving the fosamprenavir (calcium salt) in the solvent of choice. Fosamprenavir (calcium salt) is soluble in organic solvents such as ethanol, DMSO, and dimethyl formamide (DMF), which should be purged with an inert gas. The solubility of fosamprenavir (calcium salt) in ethanol is approximately 2 mg/ml and approximately 30 mg/ml in DMSO and DMF. Fosamprenavir (calcium salt) is sparingly soluble in aqueous buffers. For maximum solubility in aqueous buffers, fosamprenavir (calcium salt) should first be dissolved in DMSO and then diluted with the aqueous buffer of choice. Fosamprenavir (calcium salt) has a solubility of approximately 0.11 mg/ml in a 1:8 solution of DMSO:PBS (pH 7.2) using this method. We do not recommend storing the aqueous solution for more than one day. Description Fosamprenavir (calcium salt) is an orally bioavailable prodrug of the HIV-1 protease inhibitor amprenavir (Item No.

HIV/AIDS Formulary Instructions
2022 S a fe H a r b o r G u i d e l i n e s fo r H I V/A I D S D r u g s PPACA Guidance to Insurers: At least one form of each drug must be offered if no specific dosage is listed below. Any additional anti-retroviral medications beyond those listed should be tiered according to cost, and not according to the medical diagnosis or condition being treated. Preauthorization should not be required except in cases of suspected fraud. Drug quantities should never be limited to less than a thirty (30) day supply and any refills authorized by the treating physician. Step therapy should not be required for the administration of any of these drugs. Compliance with the safe harbor guidelines is not mandatory. However, the Office is prohibited from certifying a plan to be included on the Federal Health Insurance Marketplace if the Office knows that the plan employs a drug formulary discriminatory in benefit design, benefit implementation or medical management techniques. Additionally, the Office will disapprove any plan it finds violates Sections 627.429, 641.3007, or 641.31(3)(c)6., Florida Statutes. Lowest Generic Tier Exclusive of tiers comprised solely of preventive and value based generics Maximum cost sharing per 30-day supply: $40 • abacavir (20 mg/mL oral solution, 300 mg oral tablet) • abacavir/lamivudine (600 mg/300 mg oral tablet) • abacavir/lamivudine/zidovudine (300 mg/150 mg/300 mg oral tablet) • atazanavir (150 mg, 200 mg, 300 mg oral capsule) • didanosine (125 mg, 200 mg, 250 mg, 400 mg delayed release oral capsule) • efavirenz (50

Telzir, INN-Fosamprenavir
ANNEX I SUMMARY OF PRODUCT CHARACTERISTICS 1 1. NAME OF THE MEDICINAL PRODUCT Telzir 700 mg film-coated tablets 2. QUALITATIVE AND QUANTITATIVE COMPOSITION Each film-coated tablet contains 700 mg of fosamprenavir as fosamprenavir calcium (equivalent to approximately 600 mg of amprenavir). For the full list of excipients, see section 6.1. 3. PHARMACEUTICAL FORM Film-coated tablet Pink film coated, capsule shaped, biconvex tablets, marked with GXLL7 on one side. 4. CLINICAL PARTICULARS 4.1 Therapeutic indications Telzir in combination with low dose ritonavir is indicated for the treatment of Human Immunodeficiency Virus Type 1 (HIV-1) infected adults, adolescents and children of 6 years and above in combination with other antiretroviral medicinal products. In moderately antiretroviral experienced adults, Telzir in combination with low dose ritonavir has not been shown to be as effective as lopinavir / ritonavir. No comparative studies have been undertaken in children or adolescents. In heavily pretreated patients the use of Telzir in combination with low dose ritonavir has not been sufficiently studied. In protease inhibitor (PI) experienced patients the choice of Telzir should be based on individual viral resistance testing and treatment history (see section 5.1). 4.2 Posology and method of administration Telzir must only be given with low dose ritonavir as a pharmacokinetic enhancer of amprenavir and in combination with other antiretroviral medicinal products. The Summary of Product Characteristics of ritonavir must therefore be consulted prior to initiation of therapy with Telzir. Therapy should be initiated by a physician experienced in the management of HIV infection. Fosamprenavir is a pro-drug of amprenavir and must not be administered concomitantly with other medicinal products containing amprenavir.

Design, Synthesis, and Structure-Activity Relationship Investigation of 3’,4’-Disubstituted Pyranochromone Derivatives with Diverse Biological Activities
DESIGN, SYNTHESIS, AND STRUCTURE-ACTIVITY RELATIONSHIP INVESTIGATION OF 3’,4’-DISUBSTITUTED PYRANOCHROMONE DERIVATIVES WITH DIVERSE BIOLOGICAL ACTIVITIES Ting Zhou A dissertation submitted to the faculty of the University of North Carolina at Chapel Hill in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Eshelman School of Pharmacy. Chapel Hill 2010 Approved by Kuo-Hsiung Lee, PhD (Advisor) Kenneth F. Bastow, PhD Jian Liu, PhD Qian Shi, PhD Chin-Ho Chen, PhD i ©2010 Ting Zhou ALL RIGHTS RESERVED ii ABSTRACT TING ZHOU: DESIGN, SYNTHESIS, AND STRUCTURE-ACTIVITY RELATIONSHIP INVESTIGATION OF 3’,4’-DISUBSTITUTED PYRANOCHROMONE DERIVATIVES WITH DIVERSE BIOLOGICAL ACTIVITIES (Under the direction of Kenan Professor Kuo-Hsiung Lee) The overall goals of this research are to design and synthesize novel 3’,4’- disubstituted pyranochromone derivatives, to evaluate their anti-HIV activity and chemosensitizing potency, to elucidate structure-activity relationships (SAR), and to discover novel chemical entities. 3’R,4’R-Di-camphanoyl-khellactone analogs (DCKs) was first identified in our laboratory with high anti-HIV activity against wild-type HIV strain early in 1994. Using SAR-directed strategy, 3’R,4’R-di-camphanoyl-pyranochromone analogs (DCPs) were synthesized and evaluated in a continuing study, which showed high potency against both wild-type and multi-RT inhibitor-resistant strains. Mechanism study of DCK and its derivatives suggested that the compounds target HIV-RT in a unique way, by inhibiting its DNA-dependent DNA polymerase activity. A microwave-assisted one-pot reaction was first developed in our study and successfully applied in the preparation of 2’,2’-dimethyl-chromone motifs which were iii key intermediates in DCK and DCP derivatives.
