Pipeline Previews brings to you information on the newest drugs and medical products as they become available to the dermatologic community. This department may include additional information from the manufacturers, plus reports from physicians who wish to share their clinical experience with these new products. In addition, we will inform our readers about the latest drugs receiving Food and Drug Administration (FDA) approval.
FDA Approval of CIP-ISOTRETINOIN
Cipher Pharmaceuticals Inc. has announced that the FDA has
approved AbsoricaTM, Cipher's novel, patented brand formulation
of the acne medication isotretinoin, for the treatment of
severe recalcitrant nodular acne. Absorica is expected to be
launched in the US in fourth quarter of 2012.
Stiefel receives FDA approval of FabiorTM Foam, 0.1%
Stiefel has announced that the FDA has approved the New Drug
Application for Fabior (tazarotene) Foam, 0.1%. It is the only
retinoid in a topical foam formulation for the treatment of acne
vulgaris in patients 12 years of age and older. The approval of
tazarotene foam was based on two multi-center, randomized,
double-blind, vehicle-controlled pivotal Phase 3 studies conducted
in the US and Canada.
Perrigo Receives FDA Approval
Perrigo Company has announced final approval from the FDA
for its abbreviated new drug application (ANDA) for butoconazole
nitrate 2% vaginal cream, the generic equivalent of
Gynazole·1®. Gynazole·1® (butoconazole nitrate) vaginal cream,
2%, is indicated for the local treatment of vulvovaginal candidiasis
(infections caused by Candida). Perrigo was the first
applicant to submit a substantially complete ANDA with a paragraph
IV certification and is entitled to 180 days of marketing
exclusivity. Perrigo is working exclusively with KV Pharmaceutical
Company on a collaboration to launch the product by the
end of calendar year 2012.
Anti-PD-1 Immunotherapy BMS-936558 and Phase 1 Trial
Bristol-Myers Squibb Company has announced interim results
from the expanded Phase 1 dose-ranging study 003 (n=296)
of its investigational anti-PD-1 immunotherapy (BMS-936558),
which showed clinical activity in patients with previously-treated
non-small cell lung cancer (NSCLC), metastatic melanoma,
and renal cell carcinoma (RCC). Anti-PD-1 is a fully-human
antibody that targets the inhibitory receptor expressed on activated
T-cells called PD-1 or programmed death-1. Objective
response rates (ORs) across dose cohorts, as measured by
standard RECIST criteria, ranged from 6% to 32% in NSCLC,
19% to 41% in metastatic melanoma, and 24% to 31% in RCC.
Most responses were durable.
Drug-related serious adverse events occurred in 11% of patients
who received BMS-936558. Drug-related adverse events of special interest, defined as those with potential immunerelated
etiology, were sometimes severe and life-threatening.
The data on anti-PD-1 were published in the New England
Journal of Medicine and presented at the 48th Annual Meeting
of the American Society of Clinical Oncology. Data on a
second investigational immunotherapy from Bristol-Myers
Squibb, anti-PD-L1 (BMS-936559), were also published in the
New England Journal of Medicine and presented at the 48th
Annual Meeting of the American Society of Clinical Oncology.
BMS-936559 is fully-human antibody that targets one of the
immunosuppressive ligands for PD-1, PD-L1, which is often expressed
on tumor, stromal and immune cells. Study 003 is a
dose-ranging Phase 1 study (n=296) evaluating the safety, antitumor
activity and pharmacokinetics of BMS-936558 in patients
with advanced melanoma (n=104), non-small cell lung cancer
(n=122), renal cell carcinoma (n=34), castration-resistant prostate
cancer (n=17) and colorectal cancer (n=19).
Eligible patients were administered BMS-936558 as an intravenous
infusion every 2 weeks of each 8-week treatment cycle.
Cohorts of three to six patients per dose level (0.1, 0.3, 1.0,
3.0, or 10 mg/kg) were enrolled sequentially. Patients continued
treatment less-than or equal to 2 years (12 cycles), unless
they experienced complete response, unacceptable toxicity,
progressive disease, or withdrew consent. In clinically stable
patients, treatment could be continued beyond apparent initial
disease progression until confirmed progression, as defined
by proposed immune response criteria. Patients with stable
disease (SD) or an ongoing OR at the completion of treatment
were followed for less-than or equal to 1 year and offered retreatment
for one additional year if their disease progressed.
Objective response was defined as complete response (CR) or
partial response (PR).
Objective responses, as measured by standard RECIST criteria,
were observed in patients treated with BMS-936558 across
dose cohorts and across the NSCLC (6% to 32%), metastatic
melanoma (19% to 41%), and RCC (6% to 32%) tumor types.
Most responses were durable with response durations greaterthan
or equal to 1 year in 65% of responders with greater-than
or equal to one year follow-up.
The spectrum, frequency, and severity of treatment-related
adverse events (AEs) were generally similar across tested
dose levels. Common drug-related AEs included fatigue, rash, diarrhea, decreased appetite and nausea, with Grade 3 to 4
AEs observed in 14% of patients.
