  • Publication number: 20240082206
    Abstract: A method of treating a mammalian subject having hematologic, non-tumorous cancer cells is disclosed. The method comprises the steps of: (A) administering to such a mammalian subject a therapeutically effective amount of a halogenated xanthene, a pharmaceutically acceptable salt or a C1-C4 alkyl ester thereof as a first cancer cytotoxic agent dissolved or dispersed in a pharmaceutically acceptable aqueous medium. The mammalian subject is maintained for a period of time sufficient to induce death of hematologic, non-tumorous cancer cells. A contemplated administration is typically repeated. A contemplated treatment method can also be carried out in conjunction with administration to said mammalian subject of a second therapeutically effective amount of a second, differently-acting cancer cytotoxic agent dissolved or dispersed in a pharmaceutically acceptable medium. The second cancer cytotoxic agent can be a small molecule or an intact antibody or paratope-containing portion thereof.

  • Publication number: 20230270657
    Abstract: The present invention contemplates a topical ophthalmic system for treating a Gram-positive bacterially-infected mammalian eye. The system comprises an ophthalmic composition containing a halogenated fluorescein or a pharmaceutically acceptable salt or ester thereof dissolved or dispersed in an aqueous ophthalmic carrier and present in an anti-bacterial keratitis-treating effective concentration of about 0.2 µg/mL to about 50 µg/mL. The ophthalmic composition has a pH value of about 6.5 to about 7.6, a viscosity of about 10 to about 300 cps and an osmolality of about 270 mOsm/kg to about 340 mOsm/kg. The ophthalmic composition is present in a vessel opaque to actinic light. Also contemplated is a method of treating a mammal having a Gram-positive bacterial infection of an eye by administering the ophthalmic composition to the infected eye and maintaining the treated eye in the substantial absence of actinic light for about 3 hours to about 12 hours.

  • Publication number: 20230233515
    Abstract: This invention contemplates combined use of a rose bengal (RB) derivative with irradiation of bacteria with light to treat and kill the irradiated bacteria. In one aspect, Gram-positive bacteria are treated in a method in which the bacteria are contacted with an aqueous pharmaceutical composition containing a rose bengal (RB) compound of Formula I, discussed within, dissolved or dispersed therein at about 0.2 to about 3.1 µg/mL. Those contacted bacteria are contacted with light of the wavelength about 500 nm to about 600 nm for a time period of about 1 to about 10 minutes to provide a light dose of about 0.7 to about 7.2 J/cm2. A similar method is contemplated for treating Gram-negative bacteria that are one or more of Burkholderia, Salmonella, and Proteus using an aqueous pharmaceutical composition containing about 2 to about 15 µM concentration of the RB compound.

  • Patent number: 11426379
    Abstract: A treatment for inflammatory dermatoses, such as psoriasis and atopic dermatitis (eczema), is disclosed that utilizes topical administration of a halogenated xanthene, such as rose bengal, together with administration of one or more complementary targeted systemic dermatology therapies, preferably a therapy that addresses the inflammatory pathway and is other than an NSAID that is a COX-1 and/or COX-2 inhibitor. Examples of complementary targeted systemic therapeutic ingredients include: corticosteroids, including betamethasone dipropionate and fluocinonide; dithranol; vitamin D analogs, including calcipotriol; and retinoids, non-biologics including methotrexate, ciclosporin, hydroxycarbamide, and fumarates including dimethyl fumarate; as well as one or more biologics, including antibodies or paratope-containing antibody portions to TNF-?, antibodies to pro-inflammatory cytokines interleukin-12, interleukin-23 and interleukin-17, and TNF inhibitors.

  • Publication number: 20190030074
    Abstract: A cancer immunotherapy method is disclosed in which “induced immune anticancer agents” are isolated after being induced in an animal host by intralesional (IL) administration of a halogenated xanthene tumor-ablative compound into a solid cancerous tumor of that host animal. A sample of the induced immune anticancer agents is removed (collected) from the tumor-bearing host, banked if desired, cultured and preferentially expanded to form an immunologically-effective enriched tumor-specific immune anticancer agent composition. That composition is reintroduced in to the host from which the predecessor induced immune anticancer agents were taken, or into another immunologically suitable host in need.
