Abstract
Hematological malignancy like lymphoma originates in lymph tissues and has a propensity to spread across other organs. Managing such tumors is challenging as conventional strategies like surgery and local treatment are not plausible options and there are high chances of relapse. The advent of novel targeted therapies and antibody-mediated treatments has proven revolutionary in the management of these tumors. Although these therapies have an added advantage of specificity in comparison to the traditional chemotherapy approach, such treatment alternatives suffer from the occurrence of drug resistance and dose-related toxicities. In past decades, nanomedicine has emerged as an excellent surrogate to increase the bioavailability of therapeutic moieties along with a reduction in toxicities of highly cytotoxic drugs. Nanotherapeutics achieve targeted delivery of the therapeutic agents into the malignant cells and also have the ability to carry genes and therapeutic proteins to the desired sites. Furthermore, nanomedicine has an edge in rendering personalized medicine as one type of lymphoma is pathologically different from others. In this review, we have highlighted various applications of nanotechnology-based delivery systems based on lipidic, polymeric and inorganic nanomaterials that address different targets for effectively tackling lymphomas. Moreover, we have discussed recent advances and therapies available exclusively for managing this malignancy.

Abstract
BACKGROUND The second most common malignant cancer of the uterus is cervical cancer, which is present worldwide, has a rising death rate and is predominant in developing countries. Different classes of anticancer agents are used to treat cervical carcinoma. The use of these agents results in severe untoward side-effects, toxicity, and multidrug resistance (MDR) with higher chances of recurrence and spread beyond the pelvic region. Moreover, the resulting clinical outcome remains very poor even after surgical procedures and treatment with conventional chemotherapy. Because of the nonspecificity of their use, the agents wipe out both cancerous and normal tissues. Colloidal nano dispersions have now been focusing on site-specific delivery for cervical cancer, and there has been much advancement. METHODS This review aims to highlight the problems in the current treatment of cervical cancer and explore the potential of colloidal nanocarriers for selective delivery of anticancer drugs using available literature. RESULTS In this study, we surveyed the role and potential of different colloidal nanocarriers in cervical cancer, such as nanoemulsion, nanodispersions, polymeric nanoparticles, and metallic nanoparticles and photothermal and photodynamic therapy. We found significant advancement in colloidal nanocarrier-based cervical cancer treatment. CONCLUSION Cervical cancer-targeted treatment with colloidal nanocarriers would hopefully result in minimal toxic side effects, reduced dosage frequency, and lower MDR incidence and enhance the patient survival rates. The future direction of the study should be focused more on the regulatory barrier of nanocarriers based on clinical outcomes for cervical cancer targeting with cost-effective analysis.

Abstract
Treatment of a variety of bowel diseases like Crohn's disease, ulcerative colitis, colonic cancers, colonic pathologies, and systemic delivery of drugs at the target sites can be done with the help of targeted drug delivery technique. Conventional colon specific drug delivery systems lack specificity and release significant amount of drug prior reaching the target site. Hence, efficient drug delivery system that ensures effective release of the drug at the colon is still a sought after research arena. Ligand anchored therapy is a strong and effective approach to execute drug delivery in selective target cells, for both, diagnostic, as well as therapeutic reasons. Compared to the regular drugs, such ligand anchored therapy provides added benefit of minimum toxicity and few side effects. Discovery of overexpressed receptors on diseased cells, as compared to healthy cells led to the emergence of active drug targeting. Further, drug resistance constitutes one of the major reasons of the failure of chemotherapy and presents a major obstacle for the effective treatment. The reason behind drug resistance is exposure of pathological cells/pathogens to sub-therapeutic levels of drugs due lack of specificity of therapeutics. Active targeting, specifically taken up by the target cells, can warrant exposure of pathological cells/pathogens to high drug load at the target and sparing non-target cells hence minimal damage to normal cells and least chance of drug resistance. Many ligands like antibodies, aptamers, peptides, folate, and transferrin have been discovered in the past few years. The design of nanocarriers can be incorporated with many different functions which enables functions like imaging and triggered intracellular drug release. The present review article focuses on advances in ligand anchored therapy and its significance on the progress of targeted nanocarriers. It will also establish novel concepts like multi-targeting and multi-functional nanocarriers for the treatment of colonic disorders.

Abstract
INTRODUCTION Lymphatic vessels are the preferential route of most solid tumors to spread their metastases in the body. The onset of metastatic nests in draining lymph nodes (LNs) are a significant indicator of cancer progression and a dismaying sign of worsen staging. Therefore, the individuation and elimination of cancer cells within the lymphatic system (LS) are an important goal. Nevertheless, the targeting of the LS with traditional contrast agents and/or chemotherapeutics is difficult, due to its anatomical structure. For this reason, many studies on new lymphatic delivery systems have been carried out, both to improve lymphatic imaging and to selectively carry chemotherapeutics to LNs, reducing the exposure of healthy tissues to the cytotoxic substances. This is an overview of the present situation in the field of detection and treatment strategies of lymphatic metastases, taking into account the use of nano-drug delivery systems. Nanocarriers, thanks to their small size and other physicochemical characteristics, are suitable vectors for imaging and chemotherapy of the LS. AREAS COVERED The role of the LS in tumor progression and importance of treatment and imaging strategies of lymphatic metastases. EXPERT OPINION The nanoparticles are a promising approach for treatment and detection of lymphatic metastases. However further studies are necessary in order to evaluate their efficacy in human clinical application.

Interaction between C18 fatty acids and DOPE PEG2000 in Langmuir monolayers: effect of degree of unsaturation. J Biol Phys 2017; 43:397-414.

Abstract
In this study, we address the effect of the cis-double bond in 1,2-dioleoyl-sn-glycero-3-phosphoethanolamide-N-[methoxy(polyethylene glycol)-2000, DOPE PEG2000 (DP), on the Langmuir monolayer of C18 fatty acids-namely, stearic acid (SA), oleic acid (L1), linoleic acid (L2), and linolenic acid (L3)-with the same head group but different degrees of saturation on their hydrocarbon chains. Negative values of Gibbs free energy of mixing (ΔG mix) were obtained throughout the investigated ranges of the unsaturated C18 fatty-acid (L1, L2 and L3) mixed systems, indicating that very strong attractions occurred between molecules in the monolayers. The bend and kink effects from the cis-double bond(s) in the hydrocarbon chain affected the membrane fluidity and molecular packing in the monolayers, which resulted in a greater interaction between unsaturated C18 fatty acids and DP. The most thermodynamically stable mole composition of unsaturated C18 fatty acids to DP was observed at 50:1; this ratio is suggested to be the best mole ratio and will be subsequently used to prepare DP-C18 fatty-acid nanoliposomes. The presence of cis-double bonds in both hydrocarbon chains of DOPE in DP also created an imperfection in the membrane structure of lipid-drug delivery systems, which is expected to enhance lipid-based systems for antibody conjugation and drug encapsulation.

Abstract
Cancer is a leading cause of death in many countries around the world. However, the efficacy of current standard treatments for a variety of cancers is suboptimal. First, most cancer treatments lack specificity, meaning that these treatments affect both cancer cells and their normal counterparts. Second, many anticancer agents are highly toxic, and thus, limit their use in treatment. Third, a number of cytotoxic chemotherapeutics are highly hydrophobic, which limits their utility in cancer therapy. Finally, many chemotherapeutic agents exhibit short half-lives that curtail their efficacy. As a result of these deficiencies, many current treatments lead to side effects, noncompliance, and patient inconvenience due to difficulties in administration. However, the application of nanotechnology has led to the development of effective nanosized drug delivery systems known commonly as nanoparticles. Among these delivery systems, lipid-based nanoparticles, particularly liposomes, have shown to be quite effective at exhibiting the ability to: 1) improve the selectivity of cancer chemotherapeutic agents; 2) lower the cytotoxicity of anticancer drugs to normal tissues, and thus, reduce their toxic side effects; 3) increase the solubility of hydrophobic drugs; and 4) offer a prolonged and controlled release of agents. This review will discuss the current state of lipid-based nanoparticle research, including the development of liposomes for cancer therapy, different strategies for tumor targeting, liposomal formulation of various anticancer drugs that are commercially available, recent progress in liposome technology for the treatment of cancer, and the next generation of lipid-based nanoparticles.

Abstract
Multiple myeloma is the second most common hematologic malignancy in the US. Treatments utilizing alkylating agents, corticosteroids, proteasome inhibitors, and immunomodulatory drugs have resulted in significant survival benefits, however, despite the advances, relapse is inevitable. Decreased depth and duration of response obtained with each successive relapse of disease is typical of the disease course, thereby highlighting a continuing need for new treatment options. With the introduction of monoclonal antibodies for multiple myeloma, new options for treatment in the relapsed setting are on the horizon. Among the new immunologic agents is daratumumab (DARA), a humanized antibody to CD38 with potent multifaceted antitumor activity. Phase I and II clinical trials have demonstrated significant reduction in serum M-protein and bone marrow plasma cell percentage in refractory patients, with an acceptable toxicity profile. Moreover, ex vivo studies have shown that DARA may be particularly useful in combination with currently used anti-myeloma agents. With a recent breakthrough drug designation by the US Food and Drug Administration, DARA shows promise as mono- and combination therapy for the treatment of relapsed/refractory multiple myeloma.

Abstract
Nanoparticulate systems have demonstrated significant potential for overcoming the limitations of non-specific adverse effects related to chemotherapy. The treatment of blood malignancies employing targeted particulate drug delivery systems presents unique challenges and considerable research has been focused towards the development of targeted liposomal formulations for B cell malignancies. These formulations are aimed at achieving selectivity towards the malignant cells by targeting several cell surface markers which are over-expressed in that specific malignancy. CD19, CD20, CD22 and CD74 are few of such markers of which CD19, CD22 and CD74 are internalizing and CD20 is non-internalizing. Systems which have been developed to target both types of these cell surface markers are discussed. Specifically, the efficacy and development of targeted liposomes is considered. A number of studies have demonstrated the advantages of targeted liposomal systems encapsulating doxorubicin or vincristine. However, liposomal encapsulation of newer anti-neoplastic agents such as AD 198 which are superior to doxorubicin should be considered.

Abstract
The fluid mosaic model of Singer and Nicolson in 1972 shows how proteins are embedded in membranes. To elucidate the interactions between proteins and the surrounding lipids, stearic acid (SA) and bovine serum albumin (BSA) were used as lipid-protein components to mimic the normal membrane bilayer environment using the Langmuir-Blodgett technique. Surface pressure (π)-molecular area (A) isotherms were recorded for the SA monolayer in the presence of BSA on water. The mixed monolayer was successfully transferred onto an oxidized silicon wafer and imaged by tapping mode atomic force microscopy (AFM). Miscibility, compressibility and thermodynamic stability of the mixed system were examined. A large negative deviation of A ex, together with the minimum value of ΔG ex, was observed when the mole fraction of BSA (X BSA) was 0.8, indicating this to be the most stable mixture. In a compressibility analysis, X BSA was observed at below 50 mN m(-1), denoting a liquid-expanded phase and showing the occurrence of a strong interaction of SA with BSA molecules in this phase. AFM observations supported the quantitative data indicating that BSA was strongly attracted onto the membrane surface as predicted.

Abstract
Recent innovations and developments in nanotechnology have revolutionized cancer therapeutics. Engineered nanomaterials are the current workhorses in the emerging field of cancer nano-therapeutics. Lipid vesicles bearing anti-tumor drugs have turned out to be a clinically feasible and promising nano-therapeutic approach to treat cancer. Efficient entrapment of therapeutics, biocompatibility, biodegradability, low systemic toxicity, low immunogenicity and ability to bypass multidrug resistance mechanisms has made liposomes a versatile drug/gene delivery system in cancer chemotherapy. The present review attempts to explore the recent key advances in liposomal research and the vast arsenal of liposomal formulations currently being utilized in treatment and diagnosis of cancer.

Abstract
PURPOSE Corticosteroids are widely used for the treatment of B-cell malignancies, including non-Hodgkin lymphoma, chronic lymphocytic leukemia (CLL), and acute lymphoblastic leukemia; however, this class of drug is associated with undesirable off-target effects. Herein, we developed novel milatuzumab-conjugated liposomes as a targeted dexamethasone carrier for therapeutic delivery in CD74(+) B-cell malignancies and explored its effect against the disease. EXPERIMENTAL DESIGN The targeting efficiency of milatuzumab-targeted liposomes to CD74(+) cells was evaluated in vitro. The effect of CD74-targeted liposomal dexamethasone was compared with free dexamethasone in primary CLL cells and cell lines in vitro. The therapeutic efficacy of CD74-targeted liposomal dexamethasone was evaluated in a Raji-severe combined immunodeficient (SCID) xenograft model in vivo. RESULTS Milatuzumab-targeted liposomes promoted selective incorporation of carrier molecules into transformed CD74-positive B cells as compared with CD74-negative T-cells. The CD74-dexamethasone-targeted liposomes (CD74-IL-DEX) promoted and increased killing in CD74-positive tumor cells and primary CLL cells. Furthermore, the targeted drug liposomes showed enhanced therapeutic efficacy against a CD74-positive B-cell model as compared with free, or non-targeted, liposomal dexamethasone in SCID mice engrafted with Raji cells in vivo. CONCLUSIONS These studies provide evidence and support for a potential use of CD74-targeted liposomal dexamethasone as a new therapy for B-cell malignancies.

Abstract
The current work focuses on the study of polymeric, biodegradable nanoparticles (NPs) for the encapsulation of doxorubicin and mitomycin C (anti-leishmanial drugs), and their efficient delivery to macrophages, the parasite's home. The biodegradable polymer methoxypoly-(ethylene glycol)-b-poly (lactic acid) (MPEG-PLA) was used to prepare polymeric NPs encapsulating doxorubicin and mitomycin C. The morphology, mean diameter, and surface area of spherical NPs were determined by transmission electron microscopy (TEM), field emission scanning electron microscopy (FESEM), and BET surface area analysis. X-ray diffraction was performed to validate drug encapsulation. An in vitro release profile of the drugs suggested a fairly slow release. These polymeric NPs were efficiently capable of releasing drug inside macrophages at a slower pace than the free drug, which was monitored by epi-fluorescence microscopy. Encapsulation of doxorubicin and mitomycin C into NPs also decreases cellular toxicity in mouse macrophages (J774.1A).

Abstract
INTRODUCTION CD74, also known as the invariant chain, participates in several key processes of the immune system, including antigen presentation, B-cell differentiation and inflammatory signaling. Despite being described more than 3 decades ago, new functions and novel interactions for this evolutionarily conserved molecule are still being unraveled. As a participant in several immunological processes and an indicator of disease in some conditions, it has potential as a therapeutic target. AREAS COVERED The relationship between the structure of CD74 variants and their physiological functions is detailed in this review. The function of CD74 in several cell lineages is examined with a focus on the interactions with cathepsins and, in an inflammatory milieu, the pro-inflammatory cytokine macrophage migratory inhibitory factor. The role of CD74 signaling in inflammatory and carcinogenic processes is outlined as is the use of CD74 as a therapeutic target (in cancer) and tool (as a vaccine). EXPERT OPINION CD74 has several roles within the cell and throughout the immune system. Most prominent amongst these are the complex relationships with MIF and cathepsins. Modulation of CD74 function shows promise for the effective amelioration of disease.

Abstract
BACKGROUND Non-Hodgkin's lymphoma and multiple myeloma are often incurable and respond to a limited set of treatment options. The selective expression of CD74, the invariant chain of the MHC class II molecule, in these malignancies provides an attractive target for antibody-based therapy. OBJECTIVE This review evaluates the preclinical data for milatuzumab, a humanized antibody targeting CD74, as a treatment for non-Hodgkin's lymphomas and multiple myeloma. METHODS A review of the literature was carried out using PubMed. Current Phase I protocols using milatuzumab are summarized. RESULTS/CONCLUSION Milatuzumab is cytotoxic to lymphoma and multiple myeloma cell lines and mouse-human xenografts. The efficacy dramatically increases when milatuzumab is attached to a toxin or a radioactive agent. Phase I trials of milatuzumab are now underway in human subjects with lymphoma and multiple myeloma.

Abstract
The purpose of our research was to evaluate in vitro therapeutic efficacy of doxorubicin (DXR)-loaded immunoliposomes with Fab' fragments of the anti-CD74 antibody LL1 attached to the surface. LL1 is well suited for targeting purposes because it is internalized very fast by B-lymphoma cells. However, at in vivo application whole antibodies show fast clearance in circulation. Taking this fact into consideration, this study was initiated to elucidate the prospects of using Fab' fragments of LL1 in stead of the whole antibody for future targeting in vivo of DXR-loaded liposomes. The Fab' fragments were covalently attached to the surface of sterically stabilized liposomes by use of a PEG-based heterobifunctinal coupling agent. LL1 Fab' conjugated sterically stabilized DXR liposomes showed approximately six times faster accumulation of the drug in Raji human B-lymphoma cells than nontargeted liposomes. In vitro cytotoxicity, quantitated by a tetrazolium assay, against Raji cells gave IC(50) values of 0.13, 0.45, and 0.11 microM for DXR-loaded immunoliposomes, DXR-loaded liposomes and free drug, respectively. The results from this study suggest that DXR-loaded immunoliposomes targeted with Fab' fragments from the anti-CD74 antibody LL1 could be a useful system for future in vivo experiments.

Abstract
Here, we identified a novel peptide specifically targeting a human B cell lymphoma, Raji, through a conventional phage display method. The amino acid sequence, 'CTLPHLKMC' was obtained with the highest frequency from a nonapeptide-expressing phage library. The phage clone encoding CTLPHLKMC peptide sequence avidly bound to Raji cells compared with control phage clones. Furthermore, flow-cytometric analysis on the biotinylated synthetic CTLPHLKMC peptide demonstrated the high binding affinity to Raji cells in a dose-dependent manner whereas it has binding activity to neither human peripheral blood mononuclear cells including normal B cell derived from healthy donors nor other leukemia cells including THP-1, HL-60, Jurkat and IM-9. MALDI-TOF mass spectrometry following immunoprecipitation assay showed that a potential host receptor for the peptide is a variable region of human immunoglobulin heavy chain which would be a specific phenotypic marker of Raji. In conclusion, these results suggest that the peptide, 'CTLPHLKMC', is a specific ligand to a Raji cell.

Abstract
The aim of this study was to design a new one step conjugation of monoclonal antibodies (MAbs) to surface activated pegylated polyester nanoparticles (NPs) and evaluate the pharmacokinetic profile and therapeutic effect of paclitaxel palmitate (pcpl) loaded anti-HER2 immunoNPs in mice as compared to pcpl solution and NPs following IV injection. The density of the antibody conjugated to the NPs was found to be around 35 MAbs/NP (70% coupling efficiency). In vitro cell culture studies showed good binding and uptake results when immunoNPs were incubated with PC-3 and CAPAN-1 cell lines. Both pcpl NPs and immunoNPs showed significant increased t1/2, C(max) and AUC values as compared to the values of pcpl solution in mice. There was no significant difference in the C(max) and AUC values between pcpl NPs and pcpl immunoNPs. However, the immunoNPs concentrated much less in the liver and spleen than NPs. The pharmacokinetic behavior of the immunoNPs was markedly different from the pharmacokinetic profile of the naked MAb showing that the MAb lost its intrinsic molecular pharmacokinetic properties following conjugation to the NPs. The immunoNPs elicited a significant anti-tumor activity as compared to the pcpl solution and NPs, although the tumor growth was not fully inhibited.

Abstract
A sterically stabilized paclitaxel-loaded liposome tailored to target human breast cancer cells was developed, thereby promoting the efficiency of intracellular delivery of paclitaxel through receptor-mediated endocytosis. Results indicated that the targeting moiety (thiolated Herceptin) was successfully coupled to the distal reactive maleimide terminus of the poly (ethylene glycol)-phospholipid conjugate as well as being incorporated in the liposomal bilayers. The particle size of the PEGylated immunoliposome was maintained at about 200 nm. Confocal microscopy studies showed that the PEGylated immunoliposome was uptaken into the interior of the tumor cell through the receptor-mediated endocytosis pathway. The PEGylated immunoliposome showed substantially higher cellular uptake than the PEGylated liposome in cancer cells (BT-474 and SK-BR-3) over-expressing human epidermal growth factor receptor 2 (HER2) at 37 degrees C, while no difference was found in low HER2 expressing cells (MDA-MB-231) nor at low temperature (4 degrees C). Pharmacokinetics of paclitaxel in the PEGylated immunoliposome was compared with that in Taxol and in the PEGylated liposome in rats. The circulating time of paclitaxel in the PEGylated immunoliposome was prolonged compared to Taxol while slightly shortened than that in the PEGylated liposome. Therefore, the paclitaxel-loaded PEGylated immunoliposome using Herceptin could serve as a promising model for future tumor specific cancer therapy of HER2 over-expressing breast cancers.

Abstract
Targeted drug delivery requires binding of (and subsequent uptake by) the carrier to target cells. The purpose of our present study is to compare the binding and uptake of emulsions with different electric surface properties to SK-BR3 cell line, which over-expresses the HER2 receptor. Cationic emulsion was prepared by incorporating 0.25% w/w of the cationic lipid, stearylamine in the formulation while the anionic emulsion formulation was identical but lacking stearylamine. Immunoemulsions were prepared by conjugating the 2-iminothiolane derivative of the monoclonal antibody trastuzumab (Herceptin) through the reactive maleimide group of the octadecyl-4-(maleimidomethyl)cyclohexane-carboxylic amide linker which was incorporated in the oil phase of the anionic and cationic emulsions. Cationic emulsion exhibited a droplet size of approximately 130 nm and a zeta potential of +50 mV compared to anionic emulsion with a droplet size of approximately 140 nm and a zeta potential of -30 mV which decreased to -5 mV following antibody coupling. There was no significant difference in the coupling efficiency of trastuzumab to anionic and cationic emulsions which was in the range of 60-70%. The cationic emulsion and immunoemulsion appeared to be physically stable over a long period of time, as indicated by particle-size measurements while the droplets of the anionic immunoemulsion coalesced with time resulting in phase separation within 20 days storage at 4 degrees C. The results of binding and uptake to cells showed that both cationic and anionic immunoemulsions bind and internalized to cells much more than the respective blank emulsions. The enhanced penetration of the probe coumarin-6 with both immunoemulsions clearly indicated that the internalization process was mainly controlled by a cell-receptor endocytosis mechanism mediated by the binding affinity of trastuzumab to the cell surface receptor since the uptake of the cationic immunoemulsion was not significantly different from the uptake of the anionic immunoemulsion. However, only the cationic immunoemulsion might be considered for further investigation in view of its long standing physical stability.

Abstract
Despite several advancements in chemotherapy, the real therapy of cancer still remains a challenge. The development of new anti-cancer drugs for the treatment of cancer has not kept pace with the progress in cancer therapy, because of the nonspecific drug distribution resulting in low tumour concentrations and systemic toxicity. The main hindrance for the distribution of anti-cancer agents to the tumour site is the highly disorganized tumour vasculature, high blood viscosity in the tumour, and high interstitial pressure within the tumour tissue. Recently, several approaches such as drug modifications and development of new carrier systems for anti-cancer agents have been attempted to enhance their tumour reach. Approaches such as drug delivery through enhanced permeability and retention (EPR) effect have resulted in a significant improvement in concentration in tumours, while approaches such as drug-carrier implants and microparticles have resulted in improvement in local chemotherapy of cancer. This review discusses different strategies employed for the delivery of anti-cancer agents to tumours, such as through EPR effect, local chemotherapeutic approaches using drug delivery systems, and special strategies such as receptor-mediated delivery, pH-based carriers, application of ultrasound and delivery to resistant tumour cells and brain using nanoparticles.

Abstract
PURPOSE IMMU-110 is a drug immunoconjugate composed of doxorubicin conjugated to the humanized anti-CD74 monoclonal antibody, hLL1, at a doxorubicin/monoclonal antibody ratio of approximately 8:1 (mol/mol). CD74 is a rapidly internalizing molecule associated with HLA-DR, which has high expression by several tumor types. Here, we describe safety evaluations of IMMU-110 in mice and monkeys as well as efficacy studies in a xenograft model of the human multiple myeloma cell line, MC/CAR. EXPERIMENTAL DESIGN In vitro binding of IMMU-110 was determined by a cell-based ELISA and cytotoxicity of IMMU-110 assayed with a tetrazolium assay. Pharmacokinetics and biodistribution of radiolabeled IMMU-110 were examined in tumor-free BALB/c mice, and the therapeutic effectiveness was evaluated in severe combined immunodeficient mice bearing MC/CAR cells. Acute toxicity of IMMU-110 was studied in CD74-positive cynomolgus monkeys (Macaca fascicularis). RESULTS In vitro, IMMU-110 specifically binds to CD74 and is cytotoxic against MC/CAR cells. In vivo, IMMU-110 displayed a pharmacokinetic and biodistribution profile identical to that of unconjugated hLL1 monoclonal antibody, except for higher kidney uptake. Treatment with a single dose of IMMU-110 as low as 50 microg antibody/mouse (or 1.4 microg doxorubicin/mouse), 5 days postinjection of the multiple myeloma cells, resulted in cure of most mice. In mice, no host toxicity of IMMU-110 was observed at the highest protein dose tested (125 mg/kg). In cynomolgus monkeys, bone marrow toxicity was observed at 30 and 90 mg/kg doses. CONCLUSIONS The excellent safety and efficacy profile of IMMU-110 supports clinical testing of this immunoconjugate in the treatment of CD74-positive B-cell malignancies.

Abstract
In an attempt to design a targeted drug delivery system to tumors' over-expressing H-ferritin specifically recognized by a monoclonal antibody, AMB8LK, a cationic emulsion - AMB8LK conjugate was prepared. A novel cross-linker molecule bearing maleimide group was synthesized and added to cationic emulsion formulation for AMB8LK Fab' fragment covalent coupling. NMR spectroscopy confirmed the cross-linker synthesis and the preservation of the active maleimide function. SDS gel-electrophoresis results corroborated the formation of the Fab' fragment. Different densities of Fab' fragments (10-200 Fab'/oil droplet) were conjugated to emulsion droplet interface and no changes in the physico-chemical properties were observed ( approximately 120 nm size and zeta potential of approximately +30 mV). The coupling efficiency ranged from 55% to 70% and was visualized by TEM showing gold particles attached to the droplet interface. Cell culture studies demonstrated specific binding to cells as confirmed by the occurrence of the marked reduction in binding when free AMB8LK Mab was incubated before adding the AMB8LK-emulsion conjugate to the cells. The coupling of AMB8LK Fab' fragment to the cationic emulsion increased the cells uptake by 50% as compared to non-conjugated respective cationic emulsion. Appropriate conditions were, thus, identified for coupling AMB8LK Fab' fragment to cationic emulsion without altering the specificity and affinity of the Mab fragment to the tumor antigen.
