A Pilot Study for Evaluation of the Safety and Efficacy of Humacyte's Human Acellular Vascular Graft as an Above-Knee Femoro-Popliteal Bypass Graft in Patients With Peripheral Arterial Disease
Humacyte, Inc.
The purpose of this study is to assess the safety and efficacy of a novel, tissue-engineered vascular prosthesis, the Human Acellular Vessel (HAV). The HAV is intended as an alternative to synthetic materials and to autologous grafts in the creation of an above-knee femoro-popliteal bypass graft in patients with peripheral arterial disease.
The HAV is a sterile, non-pyrogenic, acellular tubular graft composed of human collagens and other natural extra-cellular matrix proteins. Upon implantation, it is anticipated (based on pre-clinical studies) that the collagen-based matrix comprising the graft will be infiltrated with host cells and re-modeled by the host. This will result in a vascular structure more similar to the histological composition of the native vascular tissue that may improve graft longevity and be less likely to become infected.

A Phase 2 Study for the Evaluation of Safety and Efficacy of Humacyte's Human Acellular Vessel for Use as a Vascular Prosthesis for Femoro-Popliteal Bypass in Patients With Peripheral Arterial Disease
Humacyte, Inc.
This study will evaluate how well Humacyte's Human Acellular Vessel (HAV) works when surgically implanted into a leg to improve blood flow in patients with peripheral arterial disease (PAD). This study will also evaluate how safe it is to use the HAV in this manner.
This is a prospective, open label, single treatment arm, multicenter phase 2 study to evaluate the safety and efficacy of the HAV in patients with PAD undergoing femoro-popliteal bypass surgery. The primary objective of this study is to evaluate the safety and tolerability of the HAV in these patients and to determine the patency of the Humacyte HAV at 12 months post-implantation. The secondary objectives of this study are to further assess safety in terms of PRA response, and to determine the rates of HAV interventions required to keep the HAV patent. There is no formal hypothesis testing planned; the study involves only a single, open-label treatment group.

An Exploratory, Open Label, Single Center Study of [F-18]HX4
Siemens Molecular Imaging
[F-18]HX4 is being developed as a diagnostic radiopharmaceutical for PET imaging. This trial is looking at the safety of [F-18]HX4. The Sponsor is seeking to determine if [F-18]HX4 may serve as a clinically useful hypoxia marker in diagnostic imaging, allowing the rational application of hypoxia related therapies to those patients most likely to benefit from them. Tumor hypoxia, a situation where tumor cells have been deprived of oxygen, caused cancer cells to become more resistant to the effects of radiotherapy and chemotherapy. A non-invasive study characterizing tumor hypoxia would facilitate the development of targeted therapies. The population to be studied consists of a total of ten (10) adult subjects, including, four normal volunteers and six cancer subjects, the latter with a confirmed diagnosis of head and neck cancer, as defined by the protocol eligibility criteria. The objectives of this exploratory study are to: - Gain information on bio-distribution of [F-18]HX4, and to evaluate the PET images of [F-18]HX4 for resolution, signal to background ratio for both intermediate levels of oxygenation, and at extreme levels hypoxia - Use this eIND in order to obtain the necessary information to file an IND application with the FDA. The information collected under this exploratory study will not be used for diagnostic purposes, to assess the subject's response to therapy, or for clinical management of the subject. - Begin collection of baseline imaging data - Collect [F-18]HX4 metabolism data - Gain information to improve study design and the conduct of future trials This investigation will be conducted as an exploratory, open-label, non-randomized, uncontrolled, single center, safety study. The trial is expected to begin subject enrollment in early January 2008 and end subject participation in June 2008. The duration of an individual subject's participation includes a screening visit, followed by participation in the actual study starting with the day of dosing with imaging sessions lasting several hours, concluding with a next day safety follow-up visit. Individual doses of [F-18]HX4 shall not exceed 20 mCi. The IP will be administered through a previously placed suitably sized angiocatheter or a butterfly needle. Prior to injection, qualified site personnel will assay the dose. After IP administration several PET imaging series will be acquired. Also, in order to assess major organ function and electrolyte levels, a metabolites analysis will be performed for this study from predose to 90 minutes postdose. In order to determine the quantity of [F-18]HX4 and labeled metabolites excreted by the kidney,urine will be collected and pooled at the designated intervals after administration of the investigational product. This excretion data will provide supportive information for calculating human dosimetry estimates from PET imaging biodistribution data collected in human subjects. For cancer subjects, a tissue biopsy will have been taken or be scheduled to be performed. The biopsy sample will be examined for hypoxic biomarker(s) using immunohistochemistry methods.

Clinical Evaluation of the New Hypoxia Imaging Agent HX4
Siemens Molecular Imaging
Positron Emission Tomography (PET) with fluorine-18 fluoromisonidazole (FMISO) has been used for several years as a non invasive imaging technique to study tumor hypoxia. Several experimental and clinical studies have indicated that FMISO uptake of tissues is correlated with tissue oxygen tension and that FMSO PET allows non-invasive differentiation between hypoxic and normoxic tumors. Currently, FMISO-PET represents the best characterized and validated noninvasive hypoxia imaging technique. Nevertheless, clinical studies have also shown the limitations of FMISO PET. Accumulation of FMISO in hypoxic tumors is relatively low, resulting in a low contrast between hypoxic tumors and surrounding normal tissues. In addition, imaging needs to be started relatively late after tracer injection (about 3 hours post-injection), when a significant percentage of the fluorine-18 label has already decayed and the count statistics of the PET images are relatively low. Because of these limitations, FMISO PET is still only used at a few research centers, despite high clinical interest in hypoxia imaging.
Objective of the study The aim of this study is to: - evaluate a hypoxia imaging agent, HX4, in patients with solitary tumors (i.e., locally advanced head and neck cancer) - gain information on bio-distribution of [F-18]HX4 - compare the PET images of [F-18] FMISO to [F-18]HX4 for resolution, signal to background ratio, and tumor/blood ratio

A Pilot, Phase II , Open Label, Nonrandomized, Multi- Center Study of [F 18]HX4 Positron Emission Tomography (PET) to Detect Hypoxia in Tumors
Siemens Molecular Imaging
This pilot phase II study is designed as a test and retest study to investigate [F 18]HX4 as a reliable non-invasive PET imaging marker for detection of tumor hypoxia regions and to establish a threshold for [F 18]HX4 uptake in the tumor. The study will evaluate the relationship between hypoxia biomarkers (HIF1α and CA-IX) by immunohistochemistry (IHC) and tumor uptake of [F 18]HX4 by PET imaging.
A Pilot Phase II Study The primary objectives for this study are: - To test the reproducibility of [F-18] HX-4 uptake in tumors by imaging the same patient on sequential days in a test-retest protocol - To test and confirm the relationship between hypoxia in tumors measured by hypoxia related biomarkers (HIF1α and CA-IX) with immunohistochemistry (IHC) and regional [F-18 HX-4] uptake in tumors with PET/CT. The secondary objectives for this study are: - To continue safety evaluation by the collection of safety data from all patients - To establish the threshold for hypoxia uptake in [F- 18]HX4 PET imaging - To collect data to test [F-18]HX4 PET imaging as a predictor of response in a subgroup of patients receiving treatment - To gain experience with [F-18]HX4 PET/CT in order to improve the study design to conduct future studies Design: An open label, non-randomized, uncontrolled, single group assignment, pilot efficacy study Procedures: Informed consent, collection of demographic information, medical history, blood labs, physical examination, vital signs, ECGs, two or three sets of [F-18]HX4 dosing and imaging scans including two pretreatment, and one mid-treatment if [F-18]HX4 tumor/background ratio ≥ 1.3 from pre-treatment scans, one pre-treatment [F-18]FDG, one mid-treatment if [F- 18]HX4 tumor/background ratio ≥1.3 from pre-treatment scans, concomitant medication collection, adverse event monitoring, and assessment of tumor response to treatment Patients: Approximately forty (40) patients who have diagnosis confirmed by histopathological examination of tumor tissue from head/neck, lung, liver, rectal or cervical cancers and will receive chemotherapy, radiation therapy or chemoradiotherapy.

Non Invasive Imaging of [18F]HX4 With Positron-Emission-Tomography (PET) in Head and Neck Cancer.
Maastricht Radiation Oncology
The aim of this study is to (i) Determine if tumor hypoxia can be accurately visualised with [18F] HX4 PET imaging in head and neck tumors (ii) correlate the [18F] HX4 PET images with blood and tissue markers and (iii) investigate the quality and optimal timing of [18F] HX4 PET imaging (iv) compare [18F] HX4 PET uptake with [18F] FDG PET uptake before and after treatment.
Tumor hypoxia is the situation where tumor cells are or have been deprived of oxygen. Hypoxic tumor cells are usually more resistant to radiotherapy and chemotherapy and more likely to develop metastasis. In head and neck cancer, tumor hypoxia is known to be an important prognostic factor for long term survival. [18F]HX4 is being developed as a diagnostic radiopharmaceutical for PET imaging to find a marker for hypoxia that can be used in standard clinical practice. Current hypoxia tracers lack reliable image quality and kinetics. Because of the short half life and clearance, we expect that [18F]HX4 will have a higher tumor to background ratio than current nitro-imidazole hypoxia markers such as [18F]-misonidazole. The clinical use of a reliable, non-invasive and easy to use hypoxia imaging agent could allow selection of patients most likely to benefit from hypoxia modifying therapies. Included are eligible patients with head and neck squamous cell carcinoma (T2, T3, T4, any N, M0) with tumor diameter ≥ 2,5 cm of the oral cavity, oropharynx, hypopharynx or larynx, planned to be treated with curative primary radiation treatment (+/- concurrent chemotherapy). Before treatment a standard planning [18F]FDG PET-CT will be performed, a blood sample is drawn and baseline [18F]HX4 PET scans will be performed. 18F-HX4 scans will be repeated after radiotherapy treatment with 20 +/- 4 Gy (approximately two weeks). Three months after the end of treatment a [18F]FDG PET scan will be performed.

An Exploratory Study of Combination Therapy With 3BNC117 and 10-1074 in HIV-Infected Individuals
National Institute of Allergy and Infectious Diseases (NIAID)
Background: Human immunodeficiency virus (HIV) affects the immune system. The main function of the immune system is protect you from infections and other diseases such as cancer. HIV attacks and cripples the immune system making people more susceptible to a variety of infections and cancers. Currently, the standard treatment for HIV infection is a daily administration of anti-HIV drugs. These drugs are called combination antiretroviral therapy (ART). ART is very effective at suppressing HIV, but does not cure HIV infection. ART must be taken continuously for life to be effective. ART can stop being effective if not taken correctly and can cause permanent side effects. Researchers want to see if two new products can control HIV infection without the use of ART. The products are the antibodies 3BNC117 and 10-1074. Objective: To see if 3BNC117 and 10-1074 are safe and can control HIV levels in the blood of people who are not taking ART or people who stop taking their ART during the study. . Eligibility: Adults ages 18-65 with HIV who are: - on ART and willing to stop treatment for at least 28 weeks - OR not taking ART with low levels of HIV in the blood Design: Participants will be screened with a physical exam, medical history, and blood, heart, and urine tests. Participants will get the 2 study products or salt water (placebo). A thin tube will be placed in an arm vein. Each product will be given directly into the vein for about 1 hour. To help collect blood cells to study in the laboratory, participants may have a procedure known as leukapheresis in which blood will be removed through a needle in the arm. Some of the white blood cells will be separated from the blood and used for research studies to see how 3BNC117 and 10-1074 effects HIV and the immune system. The rest of the blood will be returned to the person through another needle in the arm. Participants will have 18 study visits over 28 weeks. They will repeat some screening tests. They may have leukapheresis again. At 8 study visits, participants will get the study products or placebo. All participants will be followed for at least 24 weeks after their last dose of the study infusions. Participants who are in the Group that stops ART will be monitored closely to make sure the levels of virus in their blood do not go to high. If at any time during this the study a person develops HIV-related symptoms, or if the viral levels go up to high levels for more than 4 weeks, ART will be restarted and no further infusions of 3BNC117 and 10-1074 will be given. ...
Recent advances in antibody cloning technologies have led to the discovery of a number of highly potent and HIV-specific broadly neutralizing monoclonal antibodies (bNAbs) from B cells of HIV-infected individuals. It has been shown that certain bNAbs can prevent acquisition of the virus, suppress viral replication, delay and/or prevent plasma viral rebound following treatment interruption in Simian Immunodeficiency virus (SIV)-infected animals and block cell-to-cell transmission of laboratory-adapted HIV in vitro. In light of these encouraging outcomes, a number of clinical trials have been conducted in recent years in order to explore the feasibility of achieving sustained virologic suppression using a single bNAb in HIV-infected individuals following analytical treatment interruption (ATI). Despite the fact that repeated administration of a single bNAb was safe and well-tolerated, the vast majority of study subjects experienced plasma viral rebound following ATI, clearly demonstrating that successful passive immunotherapy will require different approach, including the use of a combination of 2 or more bNAbs to achieve extended periods of virologic suppression. Given a major emphasis on current HIV research lies in the possibility of achieving ART-free virologic remission, it is of great interest to investigate whether a combination of potent HIV- specific bNAbs, such as 3BNC117 and 10-1074, can prevent plasma viral rebound in infected individuals upon discontinuation of ART or suppress viral replication in subjects who are not taking ART.

An Exploratory Study of Combination Therapy With VRC-HIVMAB060-00-AB (VRC01) and 10-1074 in HIVInfected Individuals Undergoing Sequential Treatment Interruptions
National Institute of Allergy and Infectious Diseases (NIAID)
Background: A daily drug combination can keep human immunodeficiency virus (HIV) levels low for a long time. But if this combination antiretroviral therapy (ART) stops, HIV levels go back up. People can also develop resistance or permanent side effects. Researchers want to see if 2 new drugs can help control HIV when a person is not on ART. Objective: To see if VRC01 and 10-1074 are safe and control HIV when a person is not on ART. Eligibility: Adults 18-65 with HIV Design: All participants must agree to practice safer sex. Those who can get pregnant will have a pregnancy test every visit. Participants will be screened with: Physical exam Medicine review Blood and urine tests Some participants may need to change their HIV medicine for a brief period of time during the study. A few weeks later, participants will repeat screening tests and stop taking their HIV medicines. Interruption phase 1: Participants will have blood tests every 2 weeks, and repeat screening tests every 4 weeks. Treatment phase: Once their HIV reaches a certain level in the blood, participants will get the 2 study drugs or a salt water placebo. They will not know which they get. Each substance will be given through a thin tube in an arm vein for about 1 hour. Participants will restart their HIV medicines and repeat screening tests every 4 weeks. Interruption phase 2: Once the level of HIV in the blood becomes undetectable for 3 months, participants will again stop taking their HIV medicines and have blood tests every 2 weeks to monitor the level of HIV in the blood. Participants will restart their medicines by week 24. They will start sooner if they have certain symptoms or blood levels of HIV become too high. They will repeat most screening tests 3 times over 24 weeks.
Recent advances in antibody cloning technologies have led to the development of a number of highly potent and human immunodeficiency virus (HIV)-specific broadly neutralizing monoclonal antibodies (bNAbs) from B cells of HIV-infected individuals. It has been shown that certain bNAbs can prevent acquisition of the virus, suppress viral replication, delay and/or prevent plasma viral rebound following treatment interruption in simian/human immunodeficiency virus (SHIV)-infected animals. Preliminary data from clinical trials indicates that bNAbs may delay plasma viral rebound following interruption of antiretroviral therapy (ART) and block cell-to-cell transmission of laboratory-adapted HIV in vitro. In the above studies, suppression of plasma viremia was dependent on maintaining neutralizing serum levels of bNAbs via repeated intravenous (IV) infusions. A recent pre-clinical study in an acute SHIV-macaque model suggests a limited course of passive immunotherapy with two bNAbs (10-1074 and 3BNC117) given shortly after infection, can result in prolonged suppression of plasma viremia that is not dependent on the continuous presence of the bNAbs18. Based on CD8+ T cell depletion studies, it appears that the prolonged suppression of plasma viremia observed in these animals resulted from the induction of potent antiviral CD8+ T cell immunity by the short course bNAb treatment. The mechanism by which bNAb therapy could induce such a response is unclear but could involve the early formation of unique bNAb-SHIV immune complexes that subsequently induce an effective and durable T cell response to the virus. In light of these encouraging preclinical outcomes, it is of considerable interest to investigate whether treatment with a single infusion of two bNAbs (VRC01 and 10-1074) which target different epitopes of HIV gp120 (CD4 binding site and V3 glycan, respectively), during transient plasma viremia can induce long-lasting anti-HIV immunity capable of controlling plasma viremia in the absence of ART.

28-Day Repeat-Dose, Dose Escalation Safety and Tolerability, Pharmacokinetics, and Pharmacodynamics Study of 11-β Methyl Nortestosterone Dodecylcarbonate (11β-MNTDC) in Healthy Men
Health Decisions
This is a Phase I multicenter, double-blind, repeat dose, dose-escalating study, in healthy men to evaluate the safety and tolerability, pharmacokinetics, and pharmacodynamics of 11-β Methyl Nortestosterone Dodecylcarbonate (11β-MNTDC).
This repeat dose, dose-ranging study will be conducted at two centers: the Los Angeles Biomedical Research Institute at Harbor-UCLA Medical Center and the University of Washington. Two doses of 11β-MNTDC (200 mg and 400 mg) were selected for a dose-escalating 28-day repeat dose study. Twenty subjects will complete this study at each of the 11β-MNTDC (15 on 11β-MNTDC and 5 on placebo) yielding a total of 40 completed subjects (30 on 11β-MNTDC and 10 on placebo) across both sites. Safety will be assessed in subjects receiving the lower dosage before additional men receive the higher dose for 28 days. In addition to safety and tolerability, suppression of serum T, calculated free T, E2, gonadotropins (LH & FSH), and SHBG will also be assessed as secondary pharmacodynamic (PD) endpoints. The 24-hour detailed PK of 11β-MNTDC will be assessed on Days 1 and 28. Trough levels of 11β-MNTDC will be obtained throughout the 28-day treatment period, at 48 and 72 hours (Days 30 and 31) after the last dose and at the End of Study visit (between Days 70-76).

Nova Laboratories Limited
An open label, randomised, multiple dose, cross-over relative bioavailability and pharmacokinetics trial of a novel oral liquid and capsule formulations of 13-CRA administered to patients from 0 months - < 21 years.
All patients requiring at least two cycles of 13-CRA therapy will be eligible for recruitment into the trial. 13-CRA will be prescribed to patients according to local treatment protocols at each clinical site. The dose administered will be 200mg/m2/day for both test and reference product. Patients with a body weight of ≤12kg will receive a dose of 160 mg/m2/day. The pharmacokinetics of 13-CRA liquid (test product) and extracted from capsule (reference product) will be evaluated over two months. Prior to the initiation of 13-CRA treatment as part of the trial, patients will be randomised to receive either liquid or capsule formulation in "My-CRA month 1". The patients will then cross-over to the alternative formulation in "My-CRA month 2". The patients on the trial who require further treatment will revert to standard therapy i.e. 13-CRA extracted from capsules according to local practice.

A Phase 1/2 Open-label, Multi-center, Dose-escalation Study of Safety, Tolerability, Pharmacokinetics, Dosimetry, and Response to Repeat Dosing of 177Lu-PSMA-R2 Radio-ligand Therapy in Patients With Prostate Specific Membrane Antigen (PSMA) Positive (68Ga-PSMA-R2) Progressive Metastatic Castration-resistant Prostate Cancer, Following Previous Systemic Treatment
Advanced Accelerator Applications
This Phase 1/2 study is intended to investigate the safety, tolerability, and radiation dosimetry of 177Lu-PSMA-R2 and further assess preliminary efficacy data in patients with metastatic castration-resistant prostate cancer (mCRPC). The Phase 1 portion of the study will determine the recommended dose of 177Lu-PSMA-R2 for radio-ligand therapy (RLT) of mCRPC, and the Phase 2 portion will expand into approximately 60 patients documenting the preliminary activity (anti-tumor response) of repeated treatments administered, continuing safety assessments and collecting QoL data.
Recruitment for PROter A206T-G01-001 (NCT03490838) was halted in Phase I by sponsor decision. Phase II expansion portion of the study was never initiated. Importantly, this recruitment halt was not a consequence of any safety concern. Ongoing patients at the time of recruitment halt continued per protocol and completed the 1 year safety follow-up prior to early study termination. The primary objective of the Phase I portion of the study to assess the safety and tolerability of 177Lu-PSMA-R2 and to assess Dose Limiting Toxicities (DLTs) and determine the maximum tolerated dose (MTD) (if reached) and the recommended Phase II dose was not reached due to early recruitment halt.

A Phase 1/2 Open-label, Multi-center, Safety and Tolerability Study of a Single Dose of 68Ga-PSMA-R2 in Patients With Biochemical Relapse (BR) and Metastatic Prostate Cancer (mPCa)
Advanced Accelerator Applications
This was an open-label, multicenter, single dose, Phase I/II study to evaluate the safety and tolerability of a single administration of 3 mega Becquerel (MBq)/kg, but not less than 150 MBq and not more than 250 MBq, of 68^Ga-PSMA-R2 in adult male patients with biochemical relapse (BR) and metastatic prostate cancer (mPCa).
This study consisted of 2 parts. - During the first part (Phase I) of the study, 6 subjects with biochemically recurrent prostate cancer (PCa) received the investigational product (IP) and remained at the site for approximately 6 hours post-administration in order to assess the PK, biodistribution versus time, and dosimetry for critical organs. Subjects received a single dose of 3 MBq/kg, (>=150 and =<250 MBq), of 68^Ga-PSMA-R2 intravenously. Serial blood and urine samples were collected for PK characterization and dosimetry and whole-body PET/CT were acquired at selected time points (0 to 4 hours) to determine organ and tumor absorbed doses. Safety assessments were conducted after IP administration on Day 1, and during follow-up on Days 7 and 28. - In the second part of the study (Phase II), 2 groups of 12 subjects were enrolled (subjects with PCa in biochemical recurrence [PCa-BR], and subjects with prostate cancer in the metastatic stage [mPCa]). Based on the preliminary data analysis from the Phase I part of the study provided sufficient dosimetry data, all subjects underwent the whole body PET/CT imaging optimized for time (up to 2 time points) according to the data analysis from the Phase I part of the study. This study was comprised of 4 clinical visits and conducted in 3 study periods: screening, administration/imaging, and safety follow-up period.

RMS patients: - Previous acute exacerbations, and/or corticosteroid treatment or ACTH < 1 month before present exacerbation, - Hypersensitivity to methylprednisolone. - Prior use of immunosuppressive treatments / disease-modifying drugs (DMDs) other than interferon-beta, glatiramer acetate, fingolimod, dimethylfumarate or teriflunomide within 12 months of the index episode. Shorter periods may be allowed at the discretion of the PI and after approval from the sponsor. Subjects may continue their current therapy with interferons, glatiramer acetate, fingolimod, or teriflunomide throughout the course of the study. - Non-steroidal anti-inflammatory agents, including salicylic acid, should be avoided during the administration of the steroid therapy. If absolutely necessary they are permitted for subjects to treat interferon side effects, when the patient is not responding to acetaminophen/paracetamol. - Current or recent (within 30 days of first study treatment) treatment with any other investigational drug or participation in any other investigational study - Evidence of psychiatric illness - History of any significant cardiac, gastrointestinal, hepatic, pulmonary, renal or active immunosuppressive disease. - Immune deficiency or any other medical conditions that would preclude corticosteroid therapy. - Any patient who is pregnant or breastfeeding. A urine pregnancy test should be performed in female subjects of childbearing potential (defined as < 2 years after last menstruation and not surgically sterile) prior to the start of the study treatment. - For female subjects of childbearing potential (defined as < 2 years after last menstruation and not surgically sterile) and male subjects who are not surgically sterile or with female partners of childbearing potential: absence of effective, non-hormonal means of contraception (intrauterine contraceptive device, barrier method of contraception in conjunction with spermicidal gel) will be a contraindication. - Physical examination results or laboratory findings that may interfere with the planned treatment, affect patient compliance or place the patient at a high risk of treatment-related complications. - Known hypersensitivity to any of the cyclodextrin or any excipients in 2B3-201 (e.g. PEG, Cholesterol, HSPC or GSH).
