The present disclosure relates to a soluble microneedle and a filler composition with an excellent anti-wrinkle effect. Using the microneedle according to the present disclosure, crosslinked hyaluronic acid (hyaluronic acid filler material) can be intradermally or subcutaneously administered by a simple method, and a swelling property of the crosslinked hyaluronic acid is improved after administration, thereby exhibiting the excellent anti-wrinkle effect.

Provided are a manufacturing method of a plate precursor having a plurality of needle-like protrusions and a manufacturing method of a microneedle array, which make it possible to manufacture a plate precursor within a short period of time. A manufacturing method of a plate precursor having a needle-like protrusion includes: a preparation step of preparing a cutting tool including at least one blade conforming to an external shape of the needle-like protrusion, and a base material; and a cutting step of cutting the base material by rotating the cutting tool about a tool axis of the cutting tool and revolving the cutting tool around an axis of the needle-like protrusion to be formed on the base material to form the needle-like protrusion having a shape conforming to a shape of the cutting tool.

Compositions and methods for treating hair loss are provided. One embodiment provides a microneedle composition, which when administered to the skin of a subject promotes hair growth. The microneedle compositions include an effective amount of glucocorticoid-induced leucine zipper (GILZ) protein having an amino acid sequence that has 99 or 100% identity to SEQ ID NO: 1, or fragment thereof to promote hair growth when administered to the skin of the subject and a bioerodible, biodegradable, or biosorbable polymer, wherein the composition is formulated as bioerodible, biodegradable, or bioabsorbable microneedles. In one embodiment the GILZ protein or fragment thereof is conjugated to a cell penetrating peptide. The cell penetrating peptide can be TAT GRKKRRQRRRPQ (SEQ ID NO:4) or a variant thereof.

The present invention relates to a composition comprising a water-insoluble anti-cancer agent present as surface modified and unmodified drop particles in water, a method for producing such a composition, a lyophilizate of such a composition and such a composition for use in the treatment of cancer.

Featured are methods for the treatment or prevention of spinal muscular atrophy. Effective dosage regimens are specified. Biomarkers and kits are also provided.

A method for producing at least one microneedle containing a vaccine for transdermal delivery of the vaccine to a patient includes preparing microparticles or nanoparticles of encapsulated vaccine by preparing a solution comprising a vaccine antigen and a biocompatible polymer matrix; and spray drying the solution to form the microparticles or nanoparticles. The method includes the further steps of preparing a film composition including at least one pre-polymer solution; preparing a suspension comprising the microparticles or nanoparticles and the film composition; loading the suspension into a 3D printer; printing, via the 3D printer, at least one microneedle made from the suspension; and, converting the pre-polymer solution into a cross-linked biopolymer by exposing the at least one microneedle to UV light. Also disclosed are microneedles containing a vaccine for transdermal delivery.

Compositions, devices and methods employing therapeutic concentrations of a triptan for treatment of migraine are described. Also described are methods and apparatuses for delivery of zolmitriptan for achieving a T.sub.max as quick as 2 minutes and not later than 30 minutes in the majority of subjects.

Compositions, devices and methods employing therapeutic concentrations of a triptan for treatment of migraine are described. Also described are methods for treating migraine by administering zolmitriptan using an adhesive dermally-applied microarray (ADAM) resulting in rapid and durable pain relief, pain freedom and reduction in most bothersome migraine-associated symptoms (MBS), or a combination thereof.

Acute lymphoblastic leukemia (ALL) has not benefited from innovative immunotherapies, mainly because of the lack of actionable immune targets. Novel tumor-specific antigens (TSAs) specifically expressed by ALL cells are described herein. Most of the TSAs described herein derives from aberrantly expressed unmutated genomic sequences, such as intronic and intergenic sequences, which are not expressed in normal tissues. Nucleic acids, compositions, cells, antibodies and vaccines derived from these TSAs are described. The use of the TSAs, nucleic acids, compositions, antibodies, cells and vaccines for the treatment of leukemia such as ALL is also described.

Disclosed herein are compositions and methods related to megakaryocyte-derived extracellular vesicles derived from human pluripotent stem cells, where the megakaryocyte-derived extracellular vesicles may be utilized for drug delivery and treating various diseases.
