KOHLBERG ---------------------- Isaac T. Kohlberg Title: Vice President for Industrial Liaison Date: August, 10th, 1993 CALYPTE BIOMEDICAL CORPORATION By: /s/ David J. Robison --------------------- Title: President and CEO Date: August 12, 1993 -23 - 27 APPENDIX I DETECTION OF INFECTIOUS HIV-I IN URINE OF SEROPOSITIVE INDIVIDUALS ABSTRACT We have previously described the high prevalence of antibodies to HIV-I in urine from HIV-I seropositive individuals. Recently, we reported the presence of HIV-I proviral DNA, HIV-I RNA and p24 core protein in urine cell pellets from AIDS patients. Our data suggest that HIV-I could be transmissible via urine from seropositive individuals. Urine cell pellets and cell-free sediments from twenty urine specimens of HIV positive patients will be collected. Part of the urine cell pellet from each specimen will be incubated with TNFa which has been previously shown to be, able to stimulate the expression of HIV-I. The cells and sediments will then be cultured with PBMC from HIV-I seronegative donors. The infectivity of urine will be determined by cytopathic effects (CPE), P24 antigen assay, Polyrmerase Chain Reaction (PCR) and by Electron Microscopy. This study should help to elucidate and confirm if urine may serve as a potential infectious body fluid for HIV-I. BACKGROUND Human immunodeficiency virus type I (HIV-I), the etiologic agent of the acquired immunodeficiency syndrome (AIDS) has been isolated from the peripheral blood mononuclear cells (PBMC), and serum from infected individuals; it has also been found in other body fluids including cerebrospinal fluid, saliva, tears, vaginal secretions, breast milk, semen, and alveolar fluid.(1-5) Our laboratory reported that antibodies against HIV-I proteins are found in urine of HIV seropositive individuals (7). With the rapidly increasing incidence of HIV-I infection, the question of whether infectious virons of HIV can be detected in the urine from HIV-I-infected individuals becomes increasingly important, since urine could serve as a means of HIV-I transmission. Levy et al., detected HIV-I in one of five urine specimens examined (8). However, Skolnik et al., were unable to detect HIV-I in the urine specimens from HIV-I seropositive individuals examined (9). Recently, we reported the presence of HIV-I proviral DNA sequences in centifuged fresh cell pellets from urine of HIV-I infected individuals (10). Furthermore, we detected HIV-I RNA and p24 core protein in these urine cell pellets as well (11). The question is raised whether the urine from HIV-I infected host could potentially serve as an infectious body fluid for transmission of AIDS. 1) Urine specimens in general frequently contains small numbers of mononuclear cells (<2 x 106/24 hours); these same cells when located in blood or lymph nodes are known to serve as reservoirs of HIV. 2) A variety of renal diseases have been described in HIV-I infected patients such as nephropathy associated with tubulointersitial mononuclear cells infiltrate (12). In addition, the incidence of urinary tract infections is increased in the HIV-I infected host (12). It is probable that the number of mononuclear cells found in urine of AIDS patients may be greater than that found in healthy subjects. 3) The structural cells and tissues of the genitourinary tract, other than the mononuclear cells may be susceptible to infectious HIV-I. It has been shown that g1omerular endothelial and mesangial cells can be infected by HIV-I in vitro (13). Hypothetically, the cellular components found in the urine of an HIV-infected host could contain infectious virus. As a matter of fact, we have shown that genomic fragments of HIV-I are present in the cells found in the centrifuged urine pellets from some HIV-I sempositive individuals (11). These data suggest that HIV-I could be transmissible via urine from HIV-I seropositive individuals which has not been previously examined in great detail. In the only previous report concerning the absence of infectious HIV-I in urine of seropositive patients. 36ml of ultracentifuged urine pellets were used as the source of 28 HIV-I for cell culture; in that study the mononuclear cells found in urine pellets were likely to have been disrupted during the ultracentrifugation procedure. The infectivity of HIV-I virions of HIV-I might be diminished in presence of concentrated various salts or crystals usually found in urine, such as oxylated and urates, which would be precipitated with the virus at 40C for 1.5 hours. It has been shown that tumor necrosis factor alpha (TNFa) is capable of inducing HIV-I expression in cells infected with HIV-I (14). The activity of HIV-I found in cells of urine might be enhanced by TNF-a and therefore be more easily detected. It is possible that HIV-I virions present in urine might prove to be infectious if the conventional method used for collection and detection are modified. PRELIMINARY STUDIES AND RESULTS See two previously published papers (attached). SPECIFIC AIMS To determine whether urine from HIV-I infected individuals is potentially an infectious body fluid for the transmission of HIV-I. EXPERIMENTAL DESIGN AND PROCEDURES A) Initially the urine samples from a group of about 100 HIV-I seropositive individual will be screened for the presence of HIV-I sequences in their fresh urine pellets by Polyrmerase Chain Reaction (PCR), Reverse Transcriptation-PCR (RTR-PCR), and in situ hybridization as we have described previously (10,11). B) We expect to find at least 20 HIV-I positive urine specimens to be used for the following studies (see schematic diagram). Urine specimens will be first centrifugated at 3000 rpm at 40C for 5 minutes to obtain the cell pellets and the urine supernants will then be ultracentrifuged at 30,000 rpm at 4O C for 1.5 hr to obtain cell-free virus, if present. The urine cell pellets will be washed X3 with HBSS containing Gentarmycin 50gg/ml, and Amphotericin B l5gg/ml. The ultracentifugated cell-free sediment will be resuspended in HBSS containing these antibiotics. Half of the urine cell pellets from each individual will then be resuspended in RPMI 1640 medium supplemented with 10% fetal calf serum and 100 units of TNF-a/ml (Genzyme) at 370C for 24 hours. The cells and sediments from urine will also be cultured with 5 x 106 PBMC from HIV-I seronegative donors in RPM2 1640 medium containing 2gg/ml polybrene (Sigma, St. Louis) and 10% interleukin-2 (Sigma), supplemented with Penicillin 25ORg/ml. Streptomycin 250gg/ml, herpes buffer (0.01M), L-glutamine (2mM) and 20% heat-inactivated fetal calf serum. The donor PMBC used will have been separated by ficoll-hypaque differential centrifugation and then stimulated for 3 to 4 days with 10% IL-2 and 10gg/ml of phytohemagglutinin-p (PHA-p: Sigma. St. Louis) in RPMI-1640 medium. The cultures will be incubated at 370C in 5% CO2 atmosphere for 6 weeks. Half the media of each culture will be changed twice a week. Fresh PBMC stimulated with PHA-p will be added to the cultures once each week for 6 weeks. C) The presence of infectious HIV in Urine will be determined by: 1) Cytopathic effect (CPE) including syncytia by microscopy examination, 29 2) Cultures will be tested twice weekly for the presence of HIV-I P24 antigen. by ELISA (Abbott Laboratories) 3) Aliquots of the cell cultures will be collected once weekly to detect H1V-I DNA and/or RNA by PCR and RT-PCR methods (11). 4) Electromicroscopy examination of the culture for possible detection of HIV-I infection will be performed (15). In summary, utilizing the modified methods proposed in this proposal, we hope to ascertain whether the fragments of HIV-I we have recently detected and described in the urine pellets of seropositive individuals could represent infectious virus.

If any Holder of Registrable Securities disapproves of the terms of the underwriting, such person may elect to withdraw therefrom by written notice to the Company, the managing underwriter and the Initiating Holders. The Registrable Securities and/or other securities so withdrawn shall also be withdrawn from registration, and such Registrable Securities shall not be transferred in a public distribution prior to 90 days after the effective date of such registration, or such other shorter period of time as the underwriters may require. If by the withdrawal of such Registrable Securities a greater number of Registrable Securities held by other Holders may be included in such registration (up to the maximum of any limitation imposed by the underwriters), then the Company shall offer to all Holders who have included Registrable Securities in such underwriting the right to include additional Registrable Securities in the same proportion and manner used in determining the underwriter limitation in this Section 9.6(b). If as a result of such withdrawals, the -16- 42 Holders whose Registrable Securities are to be registered do not own a majority of the outstanding Registrable Securities, then the request for such registration shall be deemed to have been withdrawn. If the managing underwriter has not limited the number of Registrable Securities to be underwritten, the Company may include securities for its own account or for the account of others in such registration if the underwriter so agrees and if the number of Registrable Securities which would otherwise have been included in such registration and underwriting will not thereby be limited. 9.7 Form S-3-Registration.
