This invention relates generally to medicine, pharmaceutical formulations and medical devices. In alternative embodiments, provided are pharmaceutical compositions, formulations, kits and other products of manufacture, comprising a sterile hydrogel comprising a hydrogel material and active ingredients including one or a plurality of compositions or compounds, which may comprise: a biologic, a drug or an immunostimulating agent or reagent; an antigen or an immunogen, or a plurality of antigens or immunogens; an anticancer agent or reagent, or any combination thereof.
Therapeutic cancer vaccines have been approved by the FDA and a diverse range of therapeutic cancer vaccines directed against a spectrum of tumor-associated antigens are currently being evaluated in clinical trials. However, the tumor microenvironment and other immunosuppressive entities can potentially limit the efficacy of vaccines, and producing effective treatment vaccines has proven much more difficult and challenging than developing cancer preventive vaccines. To be effective, cancer treatment vaccines must achieve two goals. Like traditional vaccines and cancer preventive vaccines, cancer treatment vaccines must stimulate specific immune responses against the correct target. The immune responses must be powerful enough to overcome the barriers that cancer cells use to protect themselves from attack by B cells and killer T cells. A variety of approaches have been tried to counteract this, for example, vaccines combined with drugs or cancer therapies, e.g., as immune checkpoint inhibitors, chemotherapeutics and/or radiation, are being evaluated both in preclinical and clinical studies. New approaches in cancer immunotherapeutics are needed to address these challenges.
Chemotherapy also is important in cancer treatment, but chemotherapy drugs act by damaging high proliferating cells, and damage to normal cells results in chemotherapy toxicities and side effects. Chemotoxicity can be seen most in actively dividing tissues such bone marrow, hair follicles and gastrointestinal mucosa. New approaches in cancer chemotherapeutics are needed to address these challenges.

In alternative embodiments, the hydrogel or hydrogel material comprises a self-assembling peptide comprising: the sequence Ile-Glu-Ile-Lys-Ile-Glu-Ile-Lys-Ile-Glu-Ile-Lys-Ile (IEIK)3I (SEQ ID NO:3); or, the sequence Lys-Leu-Asp-Leu-Lys-Leu-Asp-Leu-Lys-Leu-Asp-Leu (KLDL)3 (SEQ ID NO:2); or, a 16-amino acid synthetic peptide (Ac-[RADA]4-CONH2), or SEQ ID NO:1, which optionally can be or comprise a PURAMATRIX™ (PuraMatrix™) (BD Biosciences, San Jose, Calif.), a PURASTAT™ (PuraStat™) (BD Biosciences, San Jose, Calif.), or a PURADERM™ (PuraDerm™) (3DMatrix, Ltd, Tokyo, Japan), or equivalents.
PURAMATRIX™ (PuraMatrix™) and PURASTAT™ (PuraStat™) comprise a laboratory-designed, 16-amino acid polypeptide with a repeating sequence of arginine, alanine, and aspartic acid, or RADARADARADARADA (termed RADA4 or [RADA]4) (SEQ ID NO:1). The alternating positively and negatively charged amino acids (arginine and aspartic acid), along with the non-polar alanines in-between the charged amino acids, create two distinct structural surfaces, one hydrophilic and the other hydrophobic (Zhang and Altman, 1999[5]). The RADA polypeptide monomer building blocks form β-sheet structures upon exposure to physiological concentrations of salt, i.e., tissue culture media or physiological fluids such as blood, via complementary ionic bond formation at the hydrophilic surface of the molecules (Hauser, et al. 2010 [3]).
With regard to fibril formation, the hydrophobic sides of the peptide form a double sheet inside of the fibers and the hydrophilic side forms the outside of the nanofibers that interact with water molecules, forming an extremely high water content hydrogel; for example, in one embodiment, a PURASTAT® (PuraStat®) or equivalent hydrogel comprising 2.5% RADA peptide or equivalent and 97.5% water is used to practice the invention.
PURASTAT® (PuraStat®), based on the self-assembling peptide platform technology of PURAMATRIX™ (PuraMatrix™), is a CE (Conformity Europeenne, meaning “European Conformity”) mark approved surgical hemostatic agent. PuraStat® is safe, synthetic, non-biogenic, biocompatible, resorbable peptide hydrogel with no risk of transmissible spongiform encephalopathy (TSE) transmission. PURASTAT® (PuraStat®), a fully transparent slightly viscous aqueous peptide (2.5%) solution, is sold in a pre-filled syringe and is currently available in 1 mL, 3 mL and 5 mL unit doses indicated for hemostasis in several surgical circumstances.
Provided are processes of making a hydrogel comprising a biologic, a drug or an immunostimulating agent or reagent, an antigen or an immunogen, or a plurality of antigens or immunogens, an anticancer agent or reagent, or any combination thereof, mixed with exemplary self-assembly hydrogels, e.g. self-assembling peptide hydrogels such as a PURAMATRIX™ (PuraMatrix™) (BD Biosciences, San Jose, Calif.), or a PURADERM™ (PuraDerm™) (3DMatrix, Ltd, Tokyo, Japan).
In alternative embodiments, antibiotics or other drugs are also used (e.g., are mixed) with a biologic, a drug or an immunostimulating agent or reagent, an antigen or an immunogen, or a plurality of antigens or immunogens, an anticancer agent or reagent, or any combination thereof, in the hydrogel.

Etodolac:
A suspension of 5 mg/mL dosing solution of Etodolac was prepared by mixing the continent of a capsule (300 mg) in corn oil (60 mL).
PURASTAT™/IL-2 Mixture:
250 μg/mL of IL-2 was prepared in 100 mM acetic acid. 50 μg/ml of IL-2 in 2% PURASTAT™ was prepared as followed: 0.8 mL of 2.5% PURASTAT™ was liquefy by passing through 30 gauge needle and injected into 3 mL luer lock syringe and 0.2 mL of 250 μg/mL IL-2 was loaded into 1 mL syringe. Air bubbles were removed from each syringe and both syringes were connected by female-to-female luer lock connector. The two solutions were mixed by pushing the PURASTAT™ and the IL-2 back and forth for 6 times until fully mixed. 50 μg/ml solution of IL-2 in 0.2% PURASTAT™ prepared by mixing 0.2 mL of PURASTAT™ and 0.8 mL of 62.5 μg/mL of IL-2 in a similar way as described above.
Thirty four (34) females C57BL/6N mice (Mus musculus, 18-21 g each, at the time of arrival), were received from Simonsen Laboratories (Gilroy, Calif.) on 16 May 2014 and acclimated for eleven days prior to entry onto the study. During the acclimation period, the animals were observed at least once daily for clinical signs of abnormality. The animals were group-housed (at up to 5 per cage) in plastic “shoe-box” mouse cages in a room dedicated to rodents.
Light Cycle: Twelve hours of light and twelve hours of dark were provided in the animal rooms. A fluorescent light source was used, with lights turned on at approximately 5:00 AM and turned off at approximately 05:00 PM each day.
Feed and Water: LABDIET® 5001 Rodent Diet (Purina Mills, Inc., St. Louis, Mo.) or other approved diet was provided ad libitum throughout the acclimation and treatment phases. Fresh tap water from the Sunnyvale Municipal Water Supply will be provided ad libitum to the animals via water bottles.
The study design is summarized in Table 1,
Starting on Day 7 at the light intensity HALO 6-10 and continuing for a total of twenty one consecutive days, mice of Group 3 will be dosed once daily (QD) by SC injection of 10 mg/kg (˜0.2 mg/mouse) etodolac (Eto) and single injection of a 0.5 mg propranolol pellet.
On Day 10, when tumor diameter had reached 3-5 mm in diameter, at HALO 6-10, the primary B16-F1 tumor was surgically removed. Under isoflurane anesthesia, animals of Groups 1-3 were subjected to aseptic tumor removal surgery using an electrocautery (leaving about 1 mm3 of the original tumor).
For animals of Groups 2 and 3 only, 10 mg/kg human IL-2 in 2% PURASTAT™ hydrogel applied immediately after the removal of the tumor to the dissected area. The incision was closed with steel staples. The animals were recovered and observed daily; appropriate post-surgical care provided.
Blood for serum was collected one day after surgery (Day 11), again on Days 28, 35, prior to morbid sacrifice and at necropsy; blood was collected via the facial vein, except for the final bleed, which was performed via terminal cardiocentesis. Resulted serum specimens kept frozen at −80® C. pending shipment to the analytical laboratory (Eve Technologies Corporation, Calgary, Alberta, Canada) for mouse cytokines bioanalysis.
During the in-life period clinical observations were recorded at least once daily, body weight and tumor size (dimensions) was measured once weekly and at necropsy; qualitative food consumption was measured twice weekly (BIW).
On Day 49 the mice are euthanized. At necropsy, animals were weighed; the tumor and the surrounding tissue and lungs will be harvested and weighed. The tumor and the lungs were fixed in 10% neutral buffered formalin (NBF) for histological processing and examination. NBF fixed tissues were evaluated microscopically by a board-certified veterinary pathologist. Remaining tissues were discarded without further examination.
Acclimation: There were no clinical signs of abnormality during the acclimation period. All animals were released for use in the study at the end of the acclimation period.
Clinical Observations: Clinical observations were recorded daily and are presented in Table 3 (
Body Weight: The mice were weighed prior to tumor implantation (Day 0), once weekly thereafter, and at sacrifice. Body weights are presented in Table 2,
Mortality and Survival Curve: Two mice (Animals No. 155 and 360) died on Day 10, immediately after tumor removal surgery. No significant observations were found during the post-mortem examination of these mice.
Following tumor removal, twenty one mice were sacrificed for humane reasons due to excessively large tumors (see Table 3,
Kaplan-Meier survival curve was generated for individual groups and plotted in
Tumor Size: During the course of the study, tumor dimensions were measured once weekly using a caliper. Tumor area was calculated and provided in Table 4 (see
No difference in tumor size was observed prior to tumor removal (Day 7), see
Necropsy: Necropsies were performed on all animals following death or moribund sacrifice. Major necropsy findings are provided in Table 5,
Histology: Tumors and lungs from all animals were examined histopathologically. Fixed tissues were gross trimmed, processed through a graded series of alcohols, oriented and embedded in paraffin, microtome-sectioned at 3- to 5-μm thicknesses, slide-mounted, stained with hematoxylin & eosin (H&E), and cover-slipped by standard methodology. A histology summary is provided in Table 6,
