SUPPLEMENTARY INFORMATION: The ICH was established in 1990 as a joint regulatory/industry project to improve, through harmonization, the efficiency of the process for developing and registering new medicinal products in Europe, Japan, and the United States without compromising the regulatory obligations of safety and effectiveness. In recent years, many important initiatives have been undertaken by regulatory authorities and industry associations to promote international harmonization of regulatory requirements. FDA has participated in many meetings designed to enhance harmonization and is committed to seeking scientifically based harmonized technical procedures for pharmaceutical development. One of the goals of harmonization is to identify and then reduce differences in technical requirements for medical product development among regulatory agencies. ICH was organized to provide an opportunity for harmonization initiatives to be developed with input from both regulatory and industry representatives. ICH is concerned with harmonization among the following three regions: The European Union, Japan, and the United States. The six ICH sponsors are the European Commission; the European Federation of Pharmaceutical Industries Associations; the Japanese Ministry of Health, Labor, and Welfare; the Japanese Pharmaceutical Manufacturers Association; the Centers for Drug Evaluation and Research and Biologics Evaluation and Research, FDA; and the Pharmaceutical Research and Manufacturers of America. The ICH Secretariat, which coordinates the preparation of documentation, is provided by the International Federation of Pharmaceutical Manufacturers Associations. The ICH Steering Committee includes representatives from each of the ICH sponsors and Health Canada, the European Free Trade Area and the World Health Organization. The ICH process has achieved significant harmonization of the technical VerDate jul<14>2003 18:22 Apr 06, 2005 Jkt 205001 requirements for the approval of pharmaceuticals for human use in the three ICH regions. The current ICH process and structure can be found at the following Web site: https://www.ich.org. (FDA has verified the Web site address, but we are not responsible for subsequent changes to the Web site after this document publishes in the Federal Register.) Interested persons may present data, information, or views orally or in writing, on issues pending at the public meeting. Oral presentations from the public will be scheduled between approximately 1 p.m. and 2 p.m. Time allotted for oral presentations may be limited to 10 minutes. Those desiring to make oral presentations should notify the contact person by April 14, 2005, and submit a brief statement of the general nature of the evidence or arguments they which to present, the names and addresses, phone number, FAX, and e-mail of proposed participants, and an indication of the approximate time requested to make their presentation. The topics to be discussed are the topics for discussion at the forthcoming ICH Steering Committee Meeting and ICH Expert Working Groups. One of the topics for the upcoming ICH meeting is an Efficacy Brainstorming Session focusing on the review of the existing efficacy guidelines and their need for updating as well as potential new topics for consideration. The complete set of ICH Efficacy Guidelines may be found at https://www.ich.org/ or https:// www.fda.gov/cder/guidance/index.htm. To promote a fuller discussion of this topic the public meeting will be expanded to include public input on initiatives related to current ICH efficacy guidelines and consider needs for further information both within and between existing guidances. These initiatives include electronic source data, clinical development plan summaries, Health Level 7 structured product labeling, and other initiatives including information exchange standards (e.g., eCTD and terminology standards). The agenda for the public meeting will be made available on April 15, 2005, via the internet at https:// www.fda.gov/cder/meeting/ ICH_Spring2005.htm. Dated: April 1, 2005.

HIV Neutralization by Structure-Based Enhancements of CD4-Molecular Mimicry Peter D. Kwong, Chih-chin Huang, and Tongqing Zhou (NIAID), et al. U.S. Provisional Patent Application No. 60/623,762 filed 29 Oct 2004 (DHHS Reference No. E–333–2004/0–US–01). Licensing Contact: Michael Shmilovich; 301/435–5019; shmilovm@mail.nih.gov. Available for licensing are compositions and methods for inhibiting CD4–gp120 interactions. HIV infectivity is mediated by interactions between the lymphocyte cellular protein CD4 and HIV exterior gp120 envelope glycoprotein. The invention presents crystal structures of a number of cocomplexes between CD4 mimics, CD4M33, F23, and others disclosed herein, with gp120, as well as other mimics and molecules, which interact with gp120. CD4M33 has greater affinity than F23 for HIV–1 primary isolates, whereas F23 is a better mimic of CD4 and showed greater neutralization breadth than CD4M33 against diverse isolates from HIV–1, HIV–2, and SIVcpz. These results provide a basis for the development of anti-HIV antagonists with increased breadth of neutralization. Moreover, methods are disclosed for the identification of a mimic of CD4 with possible broadspectrum activity. These methods can be used for drug screening and variant CD4 mimic production. Also, methods are provided for characterizing and evaluating protein structure, for designing candidate ligands, and for constructing CD4 mimetic antagonist or the interfacial cavity binding compounds. Finally, provided are methods for producing mono- and polyclonal antibodies for use in vaccines. Mimics binding to gp120 cause conformational change in the protein, thus exposing epitope regions for antibody recognition. The uses of the mimetics and also of a mimetic-based immunogen in inhibiting, reducing, or preventing HIV infection are also discussed.

NIH is pleased to announce as available for licensing technology related to HIV vaccines, which involves a vaccine candidate that is in phase I clinical trials. The subject technology is from a broad scientific program directed toward development of an HIV vaccine that will generate cellular and humoral immunity to HIV from different clades, which vary in regions throughout the world and which is a critical aspect to be addressed by an HIV vaccine to be administered worldwide. The vaccine candidate described herein is one of the first multiclade-component HIV vaccines to enter into clinical trials. This technology describes a candidate HIV vaccine comprising six DNA constructs, each expressing different HIV proteins, HIV Env from clades A, B, and C, and the Gag, Pol, and Nef proteins from clade B. Phase I clinical trials for this vaccine combination are currently underway. The DNA expression vectors described herein were designed to maximize protein expression levels. This technology offers a promising approach in the HIV vaccine field. Stephen Hewitt (NCI). U.S. Patent Application No. 10/928,656 filed 26 Aug 2004 (DHHS Ref. E–098– 2004–0–US–01). Licensing Contact: Cristina Thalhammer-Reyero; 301/435–4507; thalhamc@mail.nih.gov. Available for licensing and commercial development is a simple and inexpensive device and method for preparing tissue microarrays. The method includes placing a template defining an array of openings over a surface of the recipient block with receptacle holes, such that a needle or punch that contains a sample can be inserted through the openings of the template and the sample is then inserted into the receptacle hole in the recipient block. Tissue microarrays can include hundreds or even thousands of about 1mm discs of tissue specimens, fixed and arranged on a single microscope slide. Currently available tools provide means to generate hundreds of copies of this kind of slide. However, the equipment currently available can be quite complex and expensive, and thus it is often beyond the resources of many researchers. In addition to licensing, the technology is available for further development through collaborative research opportunities with the inventors. HIV Vaccine Immunogens and Immunization Strategies Chimeric HIV/SIV Polypeptide Trimers as HIV/AIDS Vaccine Candidates Gilad Ofek et al. (NIAID). U.S. Provisional Application No. 60/ 570,883 filed 14 May 2004 (DHHS Reference No. E–218–2004/0–US–01). Licensing Contact: Susan Ano; 301/435– 5515; anos@mail.nih.gov. This invention relates to novel immunogens that generate an immune response against HIV–1 gp41 in mammals. The immunogens bind to the broadly neutralizing 2F5 monoclonal antibody as well as to antibodies 4E10 and Z13. The immunogens were designed based on structural considerations from peptide-2F5 complexes. These complexes were characterized and found to have specific features, necessary to elicit an antibody response. It has been difficult to elicit broadly neutralizing antibodies against HIV–1, and this technology offers a potential solution. In addition to licensing, the technology is available for further Bernard Moss (NIAID). U.S. Provisional Application No. 60/ 510,952 filed 10 Oct 2003 (DHHS Reference No. E–356–2003/0–US–01); PCT Application filed 12 Oct 2004 (DHHS Reference No. E–356–2003/0– PCT–02). Licensing Contact: Susan Ano; 301/435– 5515; anos@mail.nih.gov. The technology describes recombinant chimeric polypeptides of HIV Env in which all or part of the Nterminal portion (85 amino acids) of gp41 is replaced with the corresponding region of SIV. These chimeric polypeptides may be potential HIV/ AIDS vaccine candidates. The substitution described above promotes efficient trimerization of the Env protein, which has been found in functional virions to have almost exclusively a trimeric structure. Therefore, by mimicking native HIV structure, the chimeric polypeptides PO 00000 Frm 00057 Fmt 4703 Sfmt 4703 E:\FR\FM\07APN1.SGM 07APN1 Federal Register / Vol. 70, No. 66 / Thursday, April 7, 2005 / Notices described in this technology could be used as immunogens for the generation of neutralizing antibodies that would bind to native HIV. The chimeric polypeptide that contains only the Nterminal portion of SIV in an HIV–1 background is particularly interesting, because several broadly neutralizing HIV–1 epitopes are present in the Cterminal segment of gp41. In addition to licensing, the technology is available for further development through collaborative research opportunities with the inventors. Antibodies Against the Amino Terminus Region of Circumsporozoite Protein Prevent the Onset of Malaria Dharmendar Rathore, Thomas McCutchan (NIAID). U.S. Provisional Application No. 60/ 532,676 filed 23 Dec 2003 (DHHS Reference No. E–176–2003/0–US–01); PCT filed. Licensing Contact: Robert Joynes; 301/ 594–6565; joynesr@mail.nih.gov. Malaria is one of the 5 major diseases of the world and a leading cause of childhood death in sub-Saharan Africa. Furthermore, the economic devastation of the disease is measured in the billions of dollars of lost wages and lowered productivity for the endemic areas of the world. In the U.S., it is a concern of travelers as well the military having to serve in those parts of the world. To date, there is no vaccine and one is not expected for another decade. The invention presented here focuses on the ability of the malarial sporozoite to infect liver cells. Previous vaccines have focused on the carboxyl end of the circumsporozoite (CSP) protein and have few successes to show. This invention utilizes the finding that the amino terminal portion of the CSP protein is required for hepatic entry. The invention includes several CSP polypeptides and constructs encoding such polypeptides that have been shown to be required for hepatic entry for vaccine development, prevention and treatment are also claimed. Methods and kit claims are included for the detection of the CSP protein in biological samples as well as for the detection of circulating antibodies of the CSP protein are also included. In addition to licensing, the technology is available for further development through collaborative research opportunities with the inventors. Determining Kinase Specificity J.S. Shaw and Y.

Licensing Contact: Cristina Thalhammer-Reyero; 301/435–4507; thalhamc@mail.nih.gov. Available for licensing and commercial development are methods, articles, software and kits for determining the spectrum of peptidyl sequences that are recognized and phosphorylated by a kinase, such as those sites on proteins involved in signal transduction pathways. More specifically, the following is disclosed: (a) Methods involving a degenerate library approaches to identify kinase specificity by identifying peptide sequences around such phosphorylation sites and ranking the peptides in preferential order after calculating a predictive score, such as the widely used position-specific scoring matrix (PSSM). The method also provides an informative graphical format for visually representing that information and software to output data in that format. The method provides significant improvements over other methods currently used for such purpose; (b) Peptide sequences identified by the method of the invention, such as: (i) The spectrum of peptidyl sequences that are recognized and phosphorylated by a kinase, (ii) peptides that include kinase recognition sites and (iii) binding entities that specifically distinguish phosphorylated versus nonphosphorylated peptidyl sequences; and (c) Kits for identifying kinase substrates including anti-peptide antibodies for research and diagnostic uses.

Licensing Contact: Peter Soukas; 301/ 435–4646; soukasp@mail.nih.gov. This invention claims Modified Vaccinia Ankara (MVA), a replicationdeficient strain of vaccinia virus, expressing Human Immunodeficiency Virus (HIV) env, gag, and pol genes, where the genes are isolated from Ugandan Clade D isolates, Kenyan Clade A isolates, and Tanzanian Clade C isolates. In a rhesus macaque SHIV model, DNA priming followed by a recombinant MVA (rMVA) booster controlled a highly pathogenic immunodeficiency challenge. Both the DNA and the rMVA components of the vaccine expressed multiple immunodeficiency virus proteins. Two DNA inoculations at zero (0) and eight (8) weeks and a single rMVA booster at twenty-four (24) weeks effectively controlled an intrarectal challenge administered seven (7) months after the booster. Additionally, the inventors have generated data showing that inoculations of rMVA induce good immune responses even without DNA priming. The inventors are continuing preclinical work on the vaccine, and have generated further data on the vaccine. Furthermore, the inventors are continuing to optimize the vaccine by genetically modifying the genes. This vaccine will be the subject of an upcoming Phase I clinical trial. These findings provide hope that a relatively simple multiprotein DNA/MVA vaccine can help to control the Acquired Immune Deficiency Syndrome (AIDS) epidemic.

Licensing Contact: Peter Soukas; 301/ 435–4646; soukasp@mail.nih.gov. Chemokine receptors are expressed by many cells, including lymphoid cells, and function to mediate cell trafficking and localization. CC chemokine receptor 5 (CCR5) is a seven-transmembrane, G protein-coupled receptor (GPCR) which regulates trafficking and effector functions of memory/effector Tlymphocytes, macrophages, and immature dendritic cells. Chemokine binding to CCR5 leads to cellular activation through pertussis toxinsensitive heterotrimeric G proteins as well as G protein-independent signalling pathways. Like many other GPCR, CCR5 is regulated by agonistdependent processes which involve G protein coupled receptor kinase (GRK)dependent phosphorylation, betaarrestin-mediated desensitization and internalization. Human CCR5 also functions as the main coreceptor for the fusion and entry of many strains of human immunodeficiency virus (HIV–1, HIV– 2). HIV-1 transmission almost invariably involves such CCR5-specific variants (designated R5); individuals lacking functional CCR5 (by virtue of homozygosity for a defective CCR5 allele) are almost completely resistant to HIV–1 infection. Specific blocking of CCR5 (e.g. with chemokine ligands, anti-CCR5 antibodies, CCR5-blocking low MW inhibitors, etc.) inhibits entry/ infection of target cells by R5 HIV strains. Cells expressing CCR5 and CD4 are useful for screening for agents that inhibit HIV by binding to CCR5. Such agents represent potential new approaches to block HIV transmission and to treat infected people. A small animal expressing both human CCR5 along with human CD4 supports entry of HIV into target cells, a necessary hurdle that must be overcome for development of a small animal model (e.g. transgenic mouse, rat, rabbit, mink) to study HIV infection and its inhibition. The invention embodies the CCR5 genetic sequence, cell lines and VerDate jul<14>2003 18:22 Apr 06, 2005 Jkt 205001 transgenic mice, the cells of which coexpress human CD4 and CCR5, and which may represent valuable tools for the study of HIV infection and for screening anti-HIV agents. The invention also embodies anti-CCR5 agents that block HIV env-mediated membrane fusion associated with HIV entry into human CD4-positive target cells or between HIV-infected cells and uninfected human CD4-positive target cells. This technology was reported in Alkhatib et al., ‘‘CC CKR5: a RANTES, MIP–1alpha, MIP–1beta receptor as a fusion cofactor for macrophage-tropic HIV–1,’’ Science 272:1955–1958 (1996).

Identification of Molecular Markers for Endometriosis in Blood Lymphocytes Using DNA Microarrays Idhaliz Flores (NHGRI), et al. PO 00000 Frm 00059 Fmt 4703 Sfmt 4703 U.S. Provisional Application filed 18 Feb 2005 (DHHS Reference No. E– 068–2005/0–US–01).

Endometriosis is a common, nonmalignant gynecological disease that affects up to 20% of women during their reproductive years. Endometriosis is characterized by the growth of endometrial tissue outside the uterus. This growth of tissue causes recurring severe pain and can lead to infertility. As the current procedure used for diagnosis is invasive and not entirely accurate, there is a need for a fast, accurate, and minimally invasive test to test for endometriosis. Using DNA microarray analysis of blood lymphocytes, the inventors have identified two gene markers expressed in blood that are able to discriminate between those women who have endometriosis and those that don’t. The two gene markers identified are interleukin-2 receptor gamma (IL–2RG, a component of cytokine receptors) and lysyl oxidase-like 1 (LOXL1, which plays an important role in collagen synthesis and has also been implicated as a growth regulatory gene). Other genes identified in the same manner and which also represent potential biomarkers for endometriosis await further validation studies. The test would be minimally invasive and quick using a blood sample from the patient. Currently, patients must undergo a laparoscopy with the diagnosis dependent upon the expertise of the surgeon performing the procedure. In addition to licensing, the technology is available for further development through collaborative research opportunities with the inventors. Increased Protein Production Drs.

There is a continuing market need to identify biological measures to enhance recombinant protein production for therapeutic inventions for the treatment of diseases. In general, the field of recombinant protein production, including inducement of protein production both by cloning and noncloning methods and incorporation of antibiotic resistance genes in vectors appeared to be relatively crowded.

which interact with gp120. CD4M33 has greater affinity than F23 for 
HIV-1 primary isolates, whereas F23 is a better mimic of CD4 and showed 
greater neutralization breadth than CD4M33 against diverse isolates 
from HIV-1, HIV-2, and SIVcpz. These results provide a basis for the 
development of anti-HIV antagonists with increased breadth of 
neutralization. Moreover, methods are disclosed for the identification 
of a mimic of CD4 with possible broad-spectrum activity. These methods 
can be used for drug screening and variant CD4 mimic production. Also, 
methods are provided for characterizing and evaluating protein 
structure, for designing candidate ligands, and for constructing CD4 
mimetic antagonist or the interfacial cavity binding compounds.
    Finally, provided are methods for producing mono- and polyclonal 
antibodies for use in vaccines. Mimics binding to gp120 cause 
conformational change in the protein, thus exposing epitope regions for 
antibody recognition. The uses of the mimetics and also of a mimetic-
based immunogen in inhibiting, reducing, or preventing HIV infection 
are also discussed. Suggestions are presented for therapeutic uses of 
the antibodies in preventing a decline in CD4 T cell levels in HIV-
positive patients.

    NIH is pleased to announce as available for licensing technology 
related to HIV vaccines, which involves a vaccine candidate that is in 
phase I clinical trials. The subject technology is from a broad 
scientific program directed toward development of an HIV vaccine that 
will generate cellular and humoral immunity to HIV from different 
clades, which vary in regions throughout the world and which is a 
critical aspect to be addressed by an HIV vaccine to be administered 
worldwide. The vaccine candidate described herein is one of the first 
multiclade-component HIV vaccines to enter into clinical trials. This 
technology describes a candidate HIV vaccine comprising six DNA 
constructs, each expressing different HIV proteins, HIV Env from clades 
A, B, and C, and the Gag, Pol, and Nef proteins from clade B. Phase I 
clinical trials for this vaccine combination are currently underway. 
The DNA expression vectors described herein were designed to maximize 
protein expression levels. This technology offers a promising approach 
in the HIV vaccine field.

HIV Vaccine Immunogens and Immunization Strategies

Gilad Ofek et al. (NIAID).
U.S. Provisional Application No. 60/570,883 filed 14 May 2004 (DHHS 
Reference No. E-218-2004/0-US-01).
Licensing Contact: Susan Ano; 301/435-5515; anos@mail.nih.gov.

    This invention relates to novel immunogens that generate an immune 
response against HIV-1 gp41 in mammals. The immunogens bind to the 
broadly neutralizing 2F5 monoclonal antibody as well as to antibodies 
4E10 and Z13. The immunogens were designed based on structural 
considerations from peptide-2F5 complexes. These complexes were 
characterized and found to have specific features, necessary to elicit 
an antibody response. It has been difficult to elicit broadly 
neutralizing antibodies against HIV-1, and this technology offers a 
potential solution.
    In addition to licensing, the technology is available for further 
development through collaborative research opportunities with the 
inventors.

Template Methods and Devices for Preparing Sample Arrays

Stephen Hewitt (NCI).
U.S. Patent Application No. 10/928,656 filed 26 Aug 2004 (DHHS Ref. E-
098-2004-0-US-01).
Licensing Contact: Cristina Thalhammer-Reyero; 301/435-4507; 
thalhamc@mail.nih.gov.

    Available for licensing and commercial development is a simple and 
inexpensive device and method for preparing tissue microarrays. The 
method includes placing a template defining an array of openings over a 
surface of the recipient block with receptacle holes, such that a 
needle or punch that contains a sample can be inserted through the 
openings of the template and the sample is then inserted into the 
receptacle hole in the recipient block. Tissue microarrays can include 
hundreds or even thousands of about 1mm discs of tissue specimens, 
fixed and arranged on a single microscope slide. Currently available 
tools provide means to generate hundreds of copies of this kind of 
slide. However, the equipment currently available can be quite complex 
and expensive, and thus it is often beyond the resources of many 
researchers.
    In addition to licensing, the technology is available for further 
development through collaborative research opportunities with the 
inventors.

Chimeric HIV/SIV Polypeptide Trimers as HIV/AIDS Vaccine Candidates

Bernard Moss (NIAID).
U.S. Provisional Application No. 60/510,952 filed 10 Oct 2003 (DHHS 
Reference No. E-356-2003/0-US-01); PCT Application filed 12 Oct 2004 
(DHHS Reference No. E-356-2003/0-PCT-02).
Licensing Contact: Susan Ano; 301/435-5515; anos@mail.nih.gov.

    The technology describes recombinant chimeric polypeptides of HIV 
Env in which all or part of the N-terminal portion (85 amino acids) of 
gp41 is replaced with the corresponding region of SIV. These chimeric 
polypeptides may be potential HIV/AIDS vaccine candidates. The 
substitution described above promotes efficient trimerization of the 
Env protein, which has been found in functional virions to have almost 
exclusively a trimeric structure. Therefore, by mimicking native HIV 
structure, the chimeric polypeptides

[[Page 17701]]

described in this technology could be used as immunogens for the 
generation of neutralizing antibodies that would bind to native HIV. 
The chimeric polypeptide that contains only the N-terminal portion of 
SIV in an HIV-1 background is particularly interesting, because several 
broadly neutralizing HIV-1 epitopes are present in the C-terminal 
segment of gp41.
    In addition to licensing, the technology is available for further 
development through collaborative research opportunities with the 
inventors.

Antibodies Against the Amino Terminus Region of Circumsporozoite 
Protein Prevent the Onset of Malaria

Dharmendar Rathore, Thomas McCutchan (NIAID).
U.S. Provisional Application No. 60/532,676 filed 23 Dec 2003 (DHHS 
Reference No. E-176-2003/0-US-01); PCT filed.
Licensing Contact: Robert Joynes; 301/594-6565; joynesr@mail.nih.gov.
    Malaria is one of the 5 major diseases of the world and a leading 
cause of childhood death in sub-Saharan Africa. Furthermore, the 
economic devastation of the disease is measured in the billions of 
dollars of lost wages and lowered productivity for the endemic areas of 
the world. In the U.S., it is a concern of travelers as well the 
military having to serve in those parts of the world. To date, there is 
no vaccine and one is not expected for another decade.
    The invention presented here focuses on the ability of the malarial 
sporozoite to infect liver cells. Previous vaccines have focused on the 
carboxyl end of the circumsporozoite (CSP) protein and have few 
successes to show. This invention utilizes the finding that the amino 
terminal portion of the CSP protein is required for hepatic entry. The 
invention includes several CSP polypeptides and constructs encoding 
such polypeptides that have been shown to be required for hepatic entry 
for vaccine development, prevention and treatment are also claimed. 
Methods and kit claims are included for the detection of the CSP 
protein in biological samples as well as for the detection of 
circulating antibodies of the CSP protein are also included.
    In addition to licensing, the technology is available for further 
development through collaborative research opportunities with the 
inventors.

    Available for licensing and commercial development are methods, 
articles, software and kits for determining the spectrum of peptidyl 
sequences that are recognized and phosphorylated by a kinase, such as 
those sites on proteins involved in signal transduction pathways. More 
specifically, the following is disclosed:
    (a) Methods involving a degenerate library approaches to identify 
kinase specificity by identifying peptide sequences around such 
phosphorylation sites and ranking the peptides in preferential order 
after calculating a predictive score, such as the widely used position-
specific scoring matrix (PSSM). The method also provides an informative 
graphical format for visually representing that information and 
software to output data in that format. The method provides significant 
improvements over other methods currently used for such purpose;
    (b) Peptide sequences identified by the method of the invention, 
such as: (i) The spectrum of peptidyl sequences that are recognized and 
phosphorylated by a kinase, (ii) peptides that include kinase 
recognition sites and (iii) binding entities that specifically 
distinguish phosphorylated versus non-phosphorylated peptidyl 
sequences; and
    (c) Kits for identifying kinase substrates including anti-peptide 
antibodies for research and diagnostic uses.
    The technology is further described in: Fujii K, Zhu G, Liu Y,

MVA Expressing Modified HIV Envelope, Gag, and Pol Genes

Bernard Moss (NIAID), Patricia Earl (NIAID), Linda Wyatt (NIAID), Leigh 
Anne Steinmeyer (EM), Thomas VanCott (EM), Matthew Harris (EM).
U.S. Provisional Application No. 60/459,175 filed 28 Mar 2003 (DHHS 
Reference No. E-023-2003/0-US-01); PCT Application filed 28 Mar 2004, 
which published as WO 2004/087201 on 14 Oct 2004 (DHHS Reference No. E-
023-2003/0-PCT-02).
Licensing Contact: Peter Soukas; 301/435-4646; soukasp@mail.nih.gov.

    This invention claims Modified Vaccinia Ankara (MVA), a 
replication-deficient strain of vaccinia virus, expressing Human 
Immunodeficiency Virus (HIV) env, gag, and pol genes, where the genes 
are isolated from Ugandan Clade D isolates, Kenyan Clade A isolates, 
and Tanzanian Clade C isolates. In a rhesus macaque SHIV model, DNA 
priming followed by a recombinant MVA (rMVA) booster controlled a 
highly pathogenic immunodeficiency challenge. Both the DNA and the rMVA 
components of the vaccine expressed multiple immunodeficiency virus 
proteins. Two DNA inoculations at zero (0) and eight (8) weeks and a 
single rMVA booster at twenty-four (24) weeks effectively controlled an 
intrarectal challenge administered seven (7) months after the booster. 
Additionally, the inventors have generated data showing that 
inoculations of rMVA induce good immune responses even without DNA 
priming.
    The inventors are continuing preclinical work on the vaccine, and 
have generated further data on the vaccine. Furthermore, the inventors 
are continuing to optimize the vaccine by genetically modifying the 
genes. This vaccine will be the subject of an upcoming Phase I clinical 
trial. These findings provide hope that a relatively simple 
multiprotein DNA/MVA vaccine can help to control the Acquired Immune 
Deficiency Syndrome (AIDS) epidemic.

    Chemokine receptors are expressed by many cells, including lymphoid 
cells, and function to mediate cell trafficking and localization. CC 
chemokine receptor 5 (CCR5) is a seven-transmembrane, G protein-coupled 
receptor (GPCR) which regulates trafficking and effector functions of 
memory/effector T-lymphocytes, macrophages, and immature dendritic 
cells. Chemokine binding to CCR5 leads to cellular activation through 
pertussis toxin-sensitive heterotrimeric G proteins as well as G 
protein-independent signalling pathways. Like many other GPCR, CCR5 is 
regulated by agonist-dependent processes which involve G protein 
coupled receptor kinase (GRK)-dependent phosphorylation, beta-arrestin-
mediated desensitization and internalization.
    Human CCR5 also functions as the main coreceptor for the fusion and 
entry of many strains of human immunodeficiency virus (HIV-1, HIV-2). 
HIV-1 transmission almost invariably involves such CCR5-specific 
variants (designated R5); individuals lacking functional CCR5 (by 
virtue of homozygosity for a defective CCR5 allele) are almost 
completely resistant to HIV-1 infection. Specific blocking of CCR5 
(e.g. with chemokine ligands, anti-CCR5 antibodies, CCR5-blocking low 
MW inhibitors, etc.) inhibits entry/infection of target cells by R5 HIV 
strains. Cells expressing CCR5 and CD4 are useful for screening for 
agents that inhibit HIV by binding to CCR5. Such agents represent 
potential new approaches to block HIV transmission and to treat 
infected people. A small animal expressing both human CCR5 along with 
human CD4 supports entry of HIV into target cells, a necessary hurdle 
that must be overcome for development of a small animal model (e.g. 
transgenic mouse, rat, rabbit, mink) to study HIV infection and its 
inhibition.
    The invention embodies the CCR5 genetic sequence, cell lines and 
transgenic mice, the cells of which coexpress human CD4 and CCR5, and 
which may represent valuable tools for the study of HIV infection and 
for screening anti-HIV agents. The invention also embodies anti-CCR5 
agents that block HIV env-mediated membrane fusion associated with HIV 
entry into human CD4-positive target cells or between HIV-infected 
cells and uninfected human CD4-positive target cells.
    This technology was reported in Alkhatib et al., ``CC CKR5: a 
RANTES, MIP-1alpha, MIP-1beta receptor as a fusion cofactor for 
macrophage-tropic HIV-1,'' Science 272:1955-1958 (1996). The technology 
is available for exclusive or nonexclusive licensing.
