EXPL Although anti-retroviral therapy (ART) is highly effective in suppressing HIV replication, it fails to eradicate the virus from HIV-infected individuals. Stable latent HIV reservoirs are rapidly established early after HIV infection. Therefore, effective strategies for eradication of the HIV reservoirs are urgently needed. We report that ingenol-3-angelate (PEP005), the only active component in a previously FDA approved drug (Picato) for the topical treatment of precancerous actinic keratosis, can effectively reactivate latent HIV in vitro and ex vivo with relatively low cellular toxicity. Biochemical analysis showed that PEP005 reactivated latent HIV through the induction of the pS643/S676-PKCdelta-8-1kappaBalpha/epsilon-NF-kappaB signaling pathway. Importantly, PEP005 alone was sufficient to induce expression of fully elongated and processed HIV RNAs in primary CD4+ T cells from HIV infected individuals receiving suppressive ART. Furthermore, PEP005 and the P-TEFb agonist, JQ1, exhibited synergism in reactivation of latent HIV with a combined effect that is 7.5-fold higher than the effect of PEP005 alone. Conversely, PEP005 suppressed HIV infection of primary CD4+ T cells through down-modulation of cell surface expression of HIV co-receptors. This anti-cancer compound is a potential candidate for advancing HIV eradication strategies.

EXPL /The purpose of this study was/ to evaluate the safety of two applications of PEP005 (ingenol mebutate) gel in superficial basal cell carcinoma. Efficacy was a secondary end-point. Randomized, vehicle-controlled, phase IIa study conducted at eight private dermatology clinics in Australia /evaluated/ a total of 60 patients with histologically confirmed superficial basal cell carcinoma (lesion size, 4-15 mm). /They/ were randomized to treatment on days 1 and 2 (Arm A) or days 1 and 8 (Arm B) and, within each arm, to ingenol mebutate gel, 0.0025%, 0.01% or 0.05%, or vehicle gel. The main outcome measures were the incidence and severity of adverse events and local skin responses in Arms A and B; lesion clearance at day 85 was a secondary measure. The incidence of adverse events was low. One patient treated with ingenol mebutate gel, 0.05% in Arm A experienced severe flaking/scaling/dryness extending beyond the application site. Non-severe, potentially treatment-related events included erythema extending beyond the application site, application-site pain and headache in two patients each. Six patients in Arm A had one or more severe local skin responses. Efficacy appeared to be dose-related and there was a trend towards higher clinical and histological lesion clearance rates in Arm A compared with Arm B. Histological clearance occurred in five of eight patients (63%) randomized to ingenol mebutate gel, 0.05% in Arm A. Two applications of ingenol mebutate gel, 0.05%, are safe and have efficacy in patients with superficial basal cell carcinoma.

Absorption
Since ingenol mebutate is a topical treatment, the systemic absorption is less than 0.1 ng/mL.
Route of Elimination
There is no route of elimination since ingenol mebutate is a topical treatment.
Volume of Distribution
There is no volume of distribution quantity since ingenol mebutate is a topical treatment.
Clearance
There is no clearance quantity since ingenol mebutate is a topical treatment.
Plasma clearance and volume of distribution (steady-state) in humans were estimated using a simple allometric correlation based on body weight. Using a one-compartment model with first-order absorption and elimination kinetics, it was estimated that dermal administration of the maximum intended clinical dose of 2 ug/kg/day would produce levels of ingenol mebutate in the blood below the LLOQ of 0.1 ng/mL. Blood clearance and volume of distribution at steady-state were predicted to range from approximately 0.22 to 1.01 L/hr/kg and approximately 0.61 L/kg, respectively. The absorption rate constant and topical bioavailability was projected to be 0.0277 hours-1 and 0.21%, respectively. A human blood Tmax of 2 hours and Cmax of 0.107 pg/mL were predicted for a 2 ug/kg/day topical dose. A minimum topical dose of 2000 ug/kg/day to humans would be required produce detectable blood levels.

After IV administration, a high to very high blood clearance, moderate to high volume of distribution at steady-state and short half-life were observed in rats, rabbits, dogs and minipigs. Following IV administration of 3(H)-ingenol mebutate to rats, drug-related radioactivity was well distributed to the tissues and there were no gender differences in the organs exposed but elimination was faster in females. In vitro, ingenol mebutate and its isomers were shown to have high plasma protein binding in rats, dogs, minipigs and humans (>99%). In rats, the majority of an intravenous dose of 3(H)-ingenol mebutate was excreted via the biliary route, with urinary excretion as a minor pathway.

After in vitro applications of 0.01%, 0.1% or 0.05% PEP005 Gels to rat, mini-pig and human skin preparations, the percutaneous absorption was generally low, with a range of 0.04% (mini-pig) to 8.68% (rat) across animal species and 0.16% to 1.93% in humans. The absorbed doses of 3(H)-ingenol mebutate were in the order of WI rat > SD rat > human > mini-pig. After topical administration of PEP005 Gel to mini-pigs, blood levels of ingenol mebutate were generally not detected, and when detected, ranged up to 0.1 ng/mL. After topical administration of ingenol mebutate to rats, blood levels were consistently quantifiable only at doses of 300 ug/kg or greater, in which case the absolute bioavailability was 2% to 4%.

The systemic exposure to Picato gel, 0.05% was assessed in two studies in a total of 16 subjects with AK, following application of approximately 1 g of Picato gel, 0.05% to an area of 100 cm2 of the dorsal forearm once daily for two consecutive days. In these studies, the blood levels of ingenol mebutate and two of its metabolites (acyl isomers of ingenol mebutate) were measured. Blood levels of ingenol mebutate and the two metabolites were below the lower limit of quantification (0.1 ng/mL) in all the blood samples of the subjects evaluated.

There is no metabolism of Picato since ingenol mebutate is a topical treatment, and ingenol mebutate does not inhibit or induce a majority of the cytochrome P450 (CYP) enzymes.
The in vitro metabolism of ingenol mebutate was qualitatively similar in blood, skin homogenates and hepatocytes of rats, dogs, minipigs and humans. Ingenol mebutate was found to be relatively stable in blood and skin homogenates, and to undergo extensive metabolism in cryopreserved hepatocytes. The major pathway in rat, dog and minipig hepatocytes was hydrolysis to ingenol, whereas the major pathway in humans was hydroxylation of ingenol mebutate. In the skin of rats, dogs, minipigs and humans, rearrangement of ingenol mebutate was predominantly to PEP015 (approximately 26% to approximately 31%) and, to a much lesser extent, PEP025 (approximately 1% to approximately 2%); hydrolysis to ingenol was minimal (0% to 0.81%). However, after topical or IV administration of ingenol mebutate to rats and minipigs, PEP025 was not detected and PEP015 was less than 10% of the corresponding ingenol mebutate concentration in the blood.

There is no half-life quantity since ingenol mebutate is a topical treatment.
The exact mechanism of action of ingenol mebutate in actinic keratosis is unknown. It is presumed to involve primary necrosis then neutrophil-mediated inflammation and antibody-dependent cell death of residual disease cells. Additionally in early studies, PEP005 was shown to be an effective activator of PKC-delta and PKC-delta translocation into nucleus and membranes. PEP005 also downregulates the expression and activity of PKC-alpha. PEP005 induced modulation of PKCs leads to Ras/Raf/MAPK and p38 activation and AKT/PKB inhibition.
We investigated the proposed necrotic mechanism of ingenol mebutate, a natural compound with anti-cancer properties in human keratinocytes, the human squamous cell carcinoma cell line HSC-5, and HeLa cervix carcinoma cells. Topical application of a clinical dose of ingenol mebutate 0.05% (1.15 mM) gel to human reconstituted full-thickness skin equivalents strongly reduced epidermal, but not dermal viability. Ingenol mebutate showed cytotoxic potency between 200-300 uM on normal and cancer cells. When keratinocytes were induced to differentiate, they became significantly less sensitive to ingenol mebutate and half-maximal induction of cell death required more than 300 uM ingenol mebutate. Cytotoxic concentrations of ingenol mebutate caused rupture of the mitochondrial network within minutes paralleled by cytosolic calcium release in all cells. Subsequently, plasma membrane integrity was lost as seen by propidium uptake into the cells. This was in sharp contrast to lysis of cells with low concentrations of the detergent Triton X-100 that permeabilized the plasma membrane within minutes without affecting organelle morphology. Buffering of intracellular calcium and inhibition of the mitochondrial permeability transition pore reduced the cytotoxic effect of ingenol mebutate in cancer cells, but not in normal keratinocytes. However, these inhibitors could not prevent cell death subsequent to prolonged incubation. Our findings reveal that ingenol mebutate does not mediate cytotoxicity by a simple lytic, necrotic mechanism, but activates distinct processes involving multiple cell organelles in a cell-type and differentiation-dependent manner. These data improve our understanding of ingenol mebutate-target cell interactions and offer new insights relevant to the removal of aberrant cells in human skin.

Squamous cell carcinoma (SCC) is the second most common human skin cancer and the second leading cause of skin cancer-related death. Recently, a new compound, ingenol mebutate, was approved for treatment of actinic keratosis, a precursor of SCC. As the mechanism of action is poorly understood, we have further investigated the mechanism of ingenol mebutate-induced cell death. We elucidate direct effects of ingenol mebutate on primary keratinocytes, patient-derived SCC cells, and a SCC cell line. Transcriptional profiling followed by pathway analysis was performed on ingenol mebutate-treated primary keratinocytes and patient-derived SCC cells to find key mediators and identify the mechanism of action. Activation of the resulting pathways was confirmed in cells and human skin explants and supported by a phosphorylation screen of treated primary cells. The necessity of these pathways was demonstrated by inhibition of certain pathway components. Ingenol mebutate inhibited viability and proliferation of all keratinocyte-derived cells in a biphasic manner. Transcriptional profiling identified the involvement of PKC/MEK/ERK signaling in the mechanism of action and inhibition of this signaling pathway rescued ingenol mebutate-induced cell death after treatment with 100 nmol/L ingenol mebutate, the optimal concentration for the first peak of response. We found the interleukin decoy receptors IL1R2 and IL13RA2 induced by ingenol mebutate in a PKC/MEK/ERK-dependent manner. Furthermore, siRNA knockdown of IL1R2 and IL13RA2 partially rescued ingenol mebutate-treated cells. In conclusion, we have shown that ingenol mebutate-induced cell death is mediated through the PKCd/MEK/ERK pathway, and we have functionally linked the downstream induction of IL1R2 and IL13RA2 expression to the reduced viability of ingenol mebutate-treated cells.

Members of the protein kinase C (PKC) family of serine-threonine kinases are important regulators of immune cell survival. Ingenol 3-angelate (PEP005) activates a broad range of PKC isoforms and induces apoptosis in acute myeloid leukemia cells by activating the PKC isoform PKCdelta. We show here that, in contrast to its effect on leukemic cells, PEP005 provides a strong survival signal to resting and activated human T cells. The antiapoptotic effect depends upon the activation of PKC. This PKC isoform is expressed in T cells but is absent in myeloid cells. Further studies of the mechanism involved in this process showed that PEP005 inhibited activated CD8(+) T cell apoptosis through the activation of NFkappaB downstream of PKC, leading to increased expression of the antiapoptotic proteins Mcl-1 and Bcl-x(L). Transfection of CD8(+) T cells with dominant-negative PKC diminished the prosurvival effect of PEP005 significantly. Ectopic expression of PKC in the acute myeloid leukemia cell line NB4 turned their response to PEP005 from an increased to decreased rate of apoptosis. Therefore, in contrast to myeloid leukemia cells, PEP005 provides a strong survival signal to T cells, and the expression of functional PKC influences whether PKC activation leads to an anti- or proapoptotic outcome in the cell types tested.
